Title: Highly corrosion-resistant, rust-prevention coating material, highly corrosion-resistant steel, and steel structure

Description:
FIELD OF THE INVENTION 
     This invention relates to a highly corrosion-resistant, rust-prevention coating material and a highly corrosion-resistant steel, particularly to a highly corrosion-resistant, rust-prevention coating material that exhibits outstanding corrosion resistance and rust prevention when applied to the surface of various types of steel, to a highly corrosion-resistant steel coated with the coating material, and to a steel structure including the steel. 
     DESCRIPTION OF THE RELATED ART 
     Rust-prevention coating materials containing large amounts of Zn particles, specifically zinc-rich paints, are in general use as rust-prevention coating materials against combating steel rusting. The Zn particles used in a zinc-rich paint are usually produced by the mist process. Zn particles (grains) produced by the mist process are spherical particles with a grain diameter distribution wherein the average grain diameter has a single frequency peak in the region of from several to several tens of μm. 
     The Zn particles are used mainly in the undercoating of heavy-duty corrosion preventive coating. The rust-prevention mechanism is characterized in utilizing the sacrificial corrosion protection effect of the Zn particles contained in the coating. 
     The rust-prevention performance of a zinc-rich paint coating therefore depends heavily on the sacrificial corrosion protection effect of the Zn particles. In some use environments, the rate of Zn consumption is so high that the protective effect with respect to the steel does not last very long. 
     Countermeasures include that of reducing the average grain diameter of the Zn particles in the coating material and that of increasing the coating thickness. But these expedients may lead to a decline in adherence to the steel and ready occurrence of coat cracking and sagging. In other words, it has been difficult to achieve a coating that offers excellent rust prevention performance while also being good in physical properties and easy to apply. The aforesaid countermeasures thus leave much to be desired. 
     In view of this situation, a need has been felt for the development of a high-performance zinc-rich paint that preserves the current merits of such paints and further exhibits sacrificial corrosion protection over the long term. A number of proposals for this purpose have been reported. 
     For example, Japanese Patent Publication (A) No. H08-151538 (&#39;538) teaches an organic coating composition reduced in Zn particle and other metal content by addition of a bonding agent and metal powder of less than −750 mV potential. 
     Inventions aimed at improving corrosion resistance by combining new alloy particles have also been reported. 
     For example, Japanese Patent Publication (A) No. H01-3111178 (&#39;178) teaches a zinc-rich paint containing Zn alloy particles and Mn particles in addition to Zn particles. And Japanese Patent Publication (A) No. 2001-164194 (&#39;194) teaches a corrosion-resistant coating material containing Zn—Al—Mg alloy particles. 
     These inventions attempt to enhance corrosion resistance by combining Zn—Mg alloy particles and an organic resin such as epoxy resin or urethane resin. 
     In addition, Japanese Patent Publication (A) No. H02-73932 (&#39;932) teaches use of an inorganic binder. The technology of this publication exploits the long-life performance of inorganic Zn—Mg particles having a metal structure composed of Zn and MgZn 2 . 
     A number of other studies have approached the issue from the aspect of particle shape. For example, Japanese Patent Publication (A) No. 2002-285102 (&#39;102) and Japanese Patent Publication (A) No. 2005-336431 (&#39;431) teach inorganic corrosion resistant coating materials containing flaky particles of Zn—Mg alloy and corrosion-resistant steels coated with the coating materials. 
     SUMMARY OF THE INVENTION 
     Although &#39;538 achieves corrosion resistance superior to that of conventional zinc-rich paints by using a binding agent and controlling metal powder potential, it is an ordinary organic coating material readily degraded in an environment involving a combination of elements like ultraviolet rays, moisture and oxygen, so that it is vulnerable to secondary issues such the need for relatively frequent maintenance. 
     Another problem with &#39;538 that must be addressed is that it generates much toxic gas during baking. 
     &#39;178 and &#39;194 use mainly organic binders and &#39;932 uses mainly an inorganic binder. All three teach use of high-corrosion-resistance particles such as Mg, Al and the like as metal particles. 
     They improve corrosion resistance by forming MgZn 2  and Mg 2 Zn 11  intermetallic compounds. Specifically, the intermetallic compounds are present inside alloy particles whose surfaces are covered with an oxide layer or Zn and Mg solid solution phase. 
     The intermetallic compound phase having high corrosion resistance therefore cannot easily appear at the alloy particle surfaces. As a result, corrosion resistance is inadequate. 
     Moreover, when low-electrical-conductivity ZnCl 2 .4Zn(OH) 2 .H 2 O forms in the main rust component, the sacrificial corrosion protection effect is not thoroughly manifested. This is another issue that must be overcome. 
     The alloy particles are most often produced by ingot fragmentation, the atomization process or the mist process. Reliable production of the alloy particles on an industrial scale is therefore impossible. This is another point requiring attention. 
     Although &#39;102 and &#39;431 teach flaky alloy particles, spray-coating of flaky alloy particles is difficult. Flaky alloy particles cannot achieve adequate coating film adherence by conventional airless spraying, so that improvement is necessary in this regard. 
     The object of this invention is therefore to provide a highly corrosion-resistant, rust-prevention coating material and a highly corrosion-resistant steel that exhibit corrosion resistance and rust prevention markedly superior to that obtainable heretofore. It achieves this object by, unlike what has been possible heretofore, producing Zn metal particles or Zn alloy particles that have two different peak grain diameters or average grain diameters, particularly Zn metal particles or Zn alloy particles having two peaks including one added on the fine-grain side, and combining these particles with an inorganic or organic binder. 
     In the present invention, Zn metal particles comprised of Zn and unavoidable impurities are dispersed in the binder of the rust-prevention coating material in an amount of 30 mass % or greater based on the dry coating film. The inventors accomplished the invention by taking advantage of the following fundamental knowledge acquired in the course of a broad-ranging study. 
     Outstanding corrosion resistance, rust prevention and coating property are exhibited when the Zn metal particles used have a grain diameter distribution including two peaks, namely, when the Zn metal particles used include both (i) fine-grain Zn metal particles of 0.05 to 5 μm peak grain diameter or 0.01 to 5 μm average grain diameter and (ii) coarse-grain Zn metal particles of 6 to 100 μm peak grain diameter or average grain diameter, and the percentage of all Zn metal particles accounted for by fine-grain Zn metal particles of 0.05 to 5 μm grain diameter expressed in volume percent is 5% to 99%. 
     The inventors further conducted a detailed study regarding the possibility of further improving the corrosion resistance and rust prevention offered by the aforesaid particles having a grain diameter distribution including two peaks. 
     As a result, they learned that a rust-prevention coating material excellent rust prevention can be obtained by using as the fine-grain Zn metal particles or coarse-grain Zn metal particles Zn alloy particles containing, in mass %, 0.01 to 30% Mg and further that a rust-prevention coating material of still more excellent rust prevention performance can be obtained by incorporating in the Zn alloy particles, in mass %, one or both of Al: 0.01 to 30% and Si: 0.01 to 3%. 
     The inventors also conducted studies focused on the shape and state of the Zn alloy particles and the Zn—Mg—Al—Si alloy particles containing one or both of Al: 0.01 to 30 mass % and Si: 0.01 to 3 mass %. 
     As a result, they ascertained that rust prevention improves, probably owing to improved spontaneous dissolving property, when the fine-grain alloy particles or coarse-grain alloy particles are not spherical but are shaped bodies that are formed by fragmentation or the like to have multiple flat or curved surfaces each enclosed by a single contour line and that have physical fragmentation (fracture) faces or cracks on the surfaces thereof. 
     A particularly noteworthy finding was that rust prevention improves dramatically when cracks of 0.01 μm or greater length and 0.01 μm or greater depth are present. The inventors further found that in this case a notable additional improvement in rust prevention is observed when one or more of the intermetallic compounds MgZn 2 , Mg 2 Zn 11 , MgZn and Mg 2 Zn 3  are present on the fragmentation surfaces. 
     The inventors further made an in-depth study with regard to a method for producing Zn metal particles having two grain-diameter frequency peaks in the grain-diameter distribution. 
     As a result, they discovered that Zn alloy particles that have not only a grain-diameter frequency peak like the conventional one but also a grain-diameter frequency peak farther to the fine-grain side than the conventional one and that exhibit even better corrosion resistance and rust prevention can be formed by producing primary particles by an ordinary method like the mist process or gas-atomization process and thereafter causing the particles to collide with one another or collide with another solid body. 
     The Zn alloy particles having the two grain-diameter frequency peaks exhibit excellent corrosion resistance and rust prevention when used as coating material pigment without modification. However, a further investigation revealed that when used as mixed with conventional, widely-employed Zn particle pigment produced by an ordinary method like the mist process or gas-atomization process, there is realized corrosion resistance and rust prevention far superior to that when conventional Zn particles are used alone. 
     The inventors further found that an organic coating material using the invention Zn metal particles or Zn alloy particles as pigment exhibits excellent corrosion resistance and rust prevention not heretofore achievable, even in a severe environment including a combination of organic coating material degrading factors like ultraviolet rays, moisture and oxygen. 
     The inventors further carried out a thorough study regarding the distribution of the Zn metal particles in the dry coating film and learned that an additional improvement in corrosion resistance and rust prevention can be achieved by concentrating the fine-grain Zn alloy particles in the film surface layer.

     DETAILED DESCRIPTION OF THE INVENTION 
     The requirements specified by the present invention will be explained in detail. 
     The invention does not particularly specify the method of producing the Zn metal particles and Zn alloy particles used. The coarse-grain Zn metal particles and coarse-grain Zn alloy particles of the invention can, for example, be produced by general-purpose powder production methods such as the mist process or the atomization process. 
     The fine-grain Zn metal particles and fine-grain Zn alloy particles can be produced by the mist process or the atomization process. They can also be produced by a physical fragmentation method that causes Zn metal particles or Zn alloy particles produced by one of the foregoing processes to collide directly or indirectly with one another. 
     As specific physical fracture methods can be mentioned, for instance, that of adding Zn metal particles or Zn alloy particles obtained by the mist process or atomization process to toluene or xylene and jetting the so-obtained slurry so as to bring counterflows into collision with one another, and that of causing a jetted stream of the slurry to collide perpendicularly with a separate flat solid body. 
     The Zn metal particles or Zn alloy particles contained in the highly corrosion-resistant, rust-prevention coating material according to the invention must be composed of (i-1) fine-grain Zn metal particles or fine-grain Zn alloy particles of 0.05 to 5 μm peak grain diameter or 0.01 to 5 μm average diameter whose grain-diameter distribution has a grain-diameter frequency distribution with a single peak and a tail on either side of the peak and (i-2) coarse-grain Zn metal particles or coarse-grain Zn alloy particles of 6 to 100 μm peak grain diameter or average grain diameter whose grain-diameter distribution has a grain-diameter frequency distribution with another single peak and a tail on either side of the peak. 
     Although Zn metal particles that have a single grain-diameter frequency distribution peak, like those contained in conventional rust-prevention coating materials, can be produced at low cost, they are limited with regard to improvement of the metal particle filling factor because, on average, particles of the same size come to be evenly distributed in the coating film. 
     Although the approach to corrosion resistance improvement has been to reduce the peak grain diameter or average grain diameter of the metal particle grain-diameter distribution, thereby increasing the filling factor, or to increase film thickness, adequate corrosion resistance improvement has not been achieved because these measures cause film cracking and sagging. 
     In contrast, the present invention imparts two grain-diameter frequency peaks to the grain-diameter distribution of the Zn metal particles or Zn alloy particles, thus increasing the filling factor and making it possible to markedly improve corrosion resistance without application of a thick coat. 
     The grain-diameter distribution of the Zn metal particles and Zn alloy particles can be determined by dispersing the Zn metal particles or Zn alloy particles in an organic solvent such as toluene or xylene having a moisture content of 0.8% or less and conducting laser scattering particle distribution analysis in this state. 
     When the moisture content is high, caution is required because the grain diameters change owing to a reaction between the Zn metal particles or Zn alloy particles and water. 
     In accordance with the principle of laser scattering analysis, the grain-diameter distribution is determined from the equivalent spherical diameters of the Zn metal particle or Zn alloy particle grain diameters. 
     The grain-diameter distribution can be represented as a histogram by representing the grain diameter d (μm) logarithmically on the horizontal axis, defining 25 to 27 d segments on the logarithmic representation for the individual orders of magnitude change in d, and linearly representing the frequency (vol %) detected for every d segment on the vertical axis. 
     In this invention, fragmenting the Zn alloy particles so as to form physical fragmentation (fracture) facets or cracks on the surfaces thereof produces an improvement in corrosion resistance exceeding the improvement in corrosion resistance that can be realized by increasing the filling factor. 
     A “physical fragmentation (fracture) face” as termed with respect to the present invention means a face shaped by a portion of a spherical particle breaking away. As explained further later, the fact of the Zn alloy particles having physical fragmentation faces makes it possible to realize a considerable improvement in corrosion resistance and rust prevention. 
     A “crack” as termed with respect to the present invention means a fissure present at the spherical particle surface of a length of 0.01 μm or greater or a depth from the surface of 0.01 μm or greater. When the length or depth of the cracks is less than 0.01 μm, an adequate improvement in corrosion resistance cannot be obtained. A length or depth of 0.01 μm or greater is therefore necessary. 
     The cracks are often formed as a byproduct of the fragmentation for obtaining the physical fragmentation faces. Regarding the abundance of cracks, it is preferable for 1 or more cracks of 0.01 μm or greater length or depth to be seen in 20% or greater of the number of Zn alloy particles per field of observation when the Zn alloy particles are observed with a scanning electron microscope or the like. 
     When the peak grain diameter of the grain-diameter distribution of the fine-grain Zn metal particles or fine-grain Zn alloy particles is less than 0.05 μm, or when the average grain diameter thereof is less than 0.01 μm, loss from the surfaces tends to occur owing to mechanical removal or chemical extraction, so that adequate sacrificial corrosion protection cannot be obtained. Therefore, the lower limit of the peak grain diameter was defined as 0.05 μm and the lower limit of the average grain diameter as 0.01 μm. 
     Two grain diameter frequency peaks cannot be obtained when the peak grain diameter or average grain diameter of the fine-grain Zn metal particles or fine-grain Zn alloy particles exceeds 5 μm, so 5 μm was defined as the upper limit. 
     The peak grain diameter or average grain diameter of the grain-diameter distribution of the coarse-grain Zn metal particles or coarse-grain Zn alloy particles was defined as 6 μm or greater because when it is less than 6 μm, the corrosion resistance and rust prevention saturate and, in addition, it becomes impossible to obtain two grain diameter frequency peaks. 
     When the peak grain diameter or average grain diameter of the grain-diameter distribution of the coarse-grain Zn metal particles or coarse-grain Zn alloy particles exceeds 100 μm, stable spray coating or brush coating cannot be achieved. The upper limit was therefore defined as 100 μm. 
     When coating property and adherence are a concern in addition to corrosion resistance, it is preferable to define the peak grain diameter or average grain diameter of the grain-diameter distribution of the fine-grain Zn metal particles or fine-grain Zn alloy particles as 1 to 4 μm and the peak grain diameter or average grain diameter of the grain-diameter distribution of the coarse-grain Zn metal particles or coarse-grain Zn alloy particles as 6 to 20 μm. 
     Further, from the viewpoint of achieving stable spray coating, it is preferable to define the peak grain diameter or average grain diameter of the grain-diameter distribution of the fine-grain Zn metal particles or fine-grain Zn alloy particles as 1.5 to 2.5 μm and the peak grain diameter or average grain diameter of the grain-diameter distribution of the coarse-grain Zn metal particles or coarse-grain Zn alloy particles as 8.5 to 11.5 μm. 
     Insofar as the particle diameters are within the foregoing ranges, no limit is placed on the width ratios of the two different grain diameter frequency peaks. However, sharper grain diameter frequency peaks are preferable from the viewpoint of maximizing rust prevention performance. 
     Among all of the particles contained in the invention highly corrosion-resistant, rust-prevention coating material, i.e., among the combined total of the fine-grain Zn metal particles or fine-grain Zn alloy particles whose peak grain diameter or average grain diameter of the grain-diameter distribution is 0.05 to 5 μm and the coarse-grain Zn metal particles or coarse-grain Zn alloy particles whose peak grain diameter or average grain diameter of the grain-diameter distribution is 6 to 100 μm, the percentage of the particles accounted for by particles of 0.05 to 5 μm diameter, expressed in volume percentage, must be 5% or greater. 
     When the percentage is less than 5%, no pronounced improvement of corrosion resistance and rust prevention is observed. 
     The maximum percentage accounted for by particles of 0.05 to 5 μm diameter contained in the invention highly corrosion-resistant, rust-prevention coating material, expressed in volume percentage, is defined as 99% because corrosion resistance improves in proportion as the percentage of fine-grain Zn metal particles or fine-grain Zn alloy particles increases. 
     At greater than 99%, however, the excessive fine-grain Zn metal particles do not contribute to, but may detract from, the effect of improving corrosion resistance. The upper limit is therefore defined as 99%. 
     Insofar as the percentage of all Zn metal particles having two grain diameter frequency peaks accounted for by Zn metal particles of 0.05 to 5 μm diameter, expressed in volume percentage, is 5 to 99%, a dramatic improvement in corrosion resistance and rust prevention can be achieved even if Zn metal particles produced by the mist process or gas atomization process are combined. 
     From the viewpoint of the applied film, it is necessary for the fine-grain Zn metal particles or fine-grain Zn alloy particles and the coarse-grain Zn metal particles or coarse-grain Zn alloy particles to be present in a total amount of 30 mass % or greater based on the dry coating film. Excellent corrosion resistance and rust prevention cannot be realized when the content is less than 30 mass %. 
     In the present invention, the presence of the two grain diameter frequency peaks enables marked improvement of corrosion resistance and rust prevention even when Zn alloy particles obtained by adding Mg, Al, Si or the like to Zn are combined with conventional Zn metal particles. 
     The corrosion resistance and rust prevention improving effect produced by the Zn alloy particles or the mixed Zn metal particles and Zn alloy particles having two grain diameter frequency peaks is more pronounced than the corrosion resistance and rust prevention improving effect produced by the Zn alloy particles having two grain diameter frequency peak. 
     Reasons for this stronger corrosion resistance improvement include, among others, an increase in the grain-diameter frequency distribution on the fine-grain side attributable to Mg addition and exposure of physical fracture facets and cracks. 
     No substantial improvement in rust prevention performance is obtained when the Mg content of the Zn alloy particles is less than 0.01 mass % and rust prevention performance declines when the Mg content exceeds 30 mass %. Mg content is therefore defined as 0.01 to 30 mass %. 
     In order to enhance physical fragmentation property and crack occurrence by adding Mg to the Zn alloy, Mg is preferably added to a content of 0.5 to 15 mass %. As Mg is more expensive than Zn, an Mg content of 0.5 to 10 mass % is economically preferable. 
     The mixing ratio of the Zn metal particles and Zn alloy particles need not be defined insofar as the aforesaid composition limits are observed. However, Mg addition produces no substantial improvement in rust prevention at an Mg content of less than 0.01 mass %, while Mg addition has a reverse effect at a content exceeding 30 mass %. The total Mg content is therefore preferably 0.01 to 30 mass %. 
     Although corrosion resistance improves with increasing Mg content, Mg is a more expensive material than Zn. Since overall material cost is therefore increased by Mg addition, the total Mg content is preferably 0.01 to 10 mass % for optimum balance between corrosion resistance and economy. 
     Moreover, the inventors discovered that addition of general-purpose Zn metal particles of 2 to 20 μm average grain diameter to Zn alloy particles having two grain diameter frequency peaks in the grain-diameter distribution enables a major improvement in economy without loss of steel corrosion resistance enhancing effect. 
     However, in this case too, it is necessary for the volume percentage of the total of the Zn alloy particles and Zn metal particles accounted for by Zn alloy particles of 0.05 to 5 μm diameter to be 5 to 99% and for the Zn alloy particles and Zn metal particles to be dispersed in a total amount of 30 mass % or greater based on the dry coating film. 
     Further, as regards the mixing of the Zn alloy particles and Zn metal particles, it is preferable from the viewpoint of improving corrosion resistance and rust prevention to conduct the mixing under a condition whereby the ratio, in mass %, of (Zn alloy particle content %): (Zn metal particle content %) is, when expressed as 1/x, such that x is 300.0 or less. 
     When x exceeds 300.0, the effect of Zn alloy particle addition toward improvement of corrosion resistance and rust prevention ceases to be observed and x must therefore be made 300.0 or less. 
     When top priority is placed on corrosion resistance, it is preferable to increase the percentage of Zn alloy particles without limit so that the percentage of Zn metal particles approaches zero. However, in the interest of striking a practical balance between corrosion resistance and economy, the ratio (Zn alloy particle content %):(Zn metal particle content %) is preferably between 1:1 and 1:120. From the aspect of mixing stability, the ratio is preferably between 1:1 and 1:30. 
     In the present invention, the average grain diameter in the grain-diameter distribution of the Zn metal particles used in the mixture is, from the standpoint of optimizing economy and filling factor, preferably 2 to 50 μm, which is an intermediate grain diameter range in the grain-diameter distribution having two grain diameter frequency peaks. 
     It is worth noting that addition of general-purpose Zn metal particles of 2 to 50 μm average grain diameter to Zn metal particles having two grain diameter frequency peaks in the grain-diameter distribution makes it possible to achieve better economy while retaining the effect of steel corrosion resistance improvement. 
     In the present invention, corrosion resistance can be increased by adding one or both of Al and Si to the Zn alloy. 
     No effect of improving rust prevention performance is obtained when the Al content of the Zn alloy particles is less than 0.01 mass %. When Al is present at content exceeding 30 mass %, it impairs the physical fragmentation property by incorporating Mg in solid solution. Al content is therefore defined as 0.01 to 30 mass %. 
     From the aspects of rust prevention performance and ease of occurrence of physical fracture facets and/or cracks, Al content is preferably 0.01 to 10 mass %, and when physical fragmentation property is a primary concern, it is preferably 0.01 to 2 mass % 
     No effect of improving coating film adherence or physical fragmentation property is obtained when the Si content of the Zn alloy particles is less than 0.01 mass %. When Si is present at a content exceeding 3 mass %, corrosion resistance declines. Si content is therefore defined as 0.01 to 3 mass %. In order to maximize coating film adherence and corrosion resistance, Si content is preferably 0.1 to 1 mass %. 
     The mixing ratio of Al and Si in the coating film need not be defined insofar as the Al and Si contents are within the aforesaid ranges. From the viewpoint of corrosion resistance, the contents are preferably Al: 0.01 to 1.0 mass % and Si: 0.01 to 1.0 mass %. 
     The Zn alloy particles containing Mg contain intermetallic compounds and can be provided with physical fragmentation faces and/or cracks on their outer surface during the fine alloy particle production process. 
     The intermetallic compounds are compounds of Mg and Zn combined in simple whole-number ratios. Examples include MgZn 2 , Mg 2 Zn 11 , MgZn, Mg 2 Zn 3 , and Mg 7 Zn 3 . Among these intermetallic compound, MgZn 2  and Mg 2 Zn 11  are particularly preferable from the viewpoint of fragmentation property and corrosion resistance. 
     Corrosion resistance and rust prevention improve further when the metal particles are not spherical but are physically fragmented into the shape of sphere-like polyhedrons. The sphere-like polyhedrons are quasi-spheres formed by physical fragmentation of spherical particles. Polyhedrons having 2 or more faces are preferable for optimizing the balance among coating film adherence, economy and corrosion resistance. Polyhedrons having 6 or more faces are preferable for corrosion resistance improvement. 
     Such Zn metal particles and Zn alloy particles are dispersed in a vehicle (liquid binder) to obtain the highly corrosion-resistant, rust-prevention coating material of this invention. Usable vehicles include, for example, inorganic binders such as alkyl silicate and alkali silicate, and organic binders such as epoxy resin, urethane resin, phenoxy resin and polyester resin. 
     Other liquid binders are also usable, including any of the liquid binders used in zinc-rich paints. The coating material can be either of the emulsion type or the solvent type. 
     Other ordinary additives can be incorporated within ranges not impairing corrosion resistance For example, when the coating material is to be used to form a corrosion preventive primer coat, a third component such as boron can be added to enhance adherence with the topcoat. 
     In order to achieve rust prevention capability, the mixing of the Zn metal particles and Zn alloy particles with the binder must be conducted so that the total of fine Zn metal particles or fine-grain Zn alloy particles and coarse-grain Zn metal particles or coarse-grain Zn alloy particles are evenly dispersed in an amount of 30 mass % or greater based on the dry coating film. From the viewpoint of good balance among the three properties of corrosion resistance, workability and cuttablility, the amount dispersed is preferably 40 to 65 mass %. 
     By keeping the moisture content of the produced coating material at 0.8% or less, it is possible to ensure that the fine-grain and coarse-grain Zn metal particles and the fine-grain and coarse-grain Zn alloy particles maintain their suitable stability and reactivity performance, thereby enabling production of a corrosion preventive coating material excellent in rust prevention. 
     When the highly corrosion-resistant, rust-prevention coating material according to the present invention is prepared using an inorganic binder such as alkali silicate or alkyl silicate, it is preferable at the time of applying it to a steel plate or other steel material to pretreat the base material to some degree so as to ensure strong adherence. 
     Although application following treatment with a hand tool or power tool is acceptable, application after blasting is desirable for obtaining high bonding strength. 
     When an organic binder such as epoxy resin, urethane resin, phenoxy resin or polyester resin is used, good results can be obtained by direct application to the steel plate or material. However, a coated steel plate or the like having still more excellent corrosion resistance can be obtained by subjecting the surface to blasting, phosphating or chromating beforehand. 
     The reason for defining the lower limit of coating thickness as 2 μm is that a coated material of adequate corrosion resistance and rust prevention cannot be obtained when the coating is thinner than 2 μm. Although rust prevention improves with increasing coat thickness, the upper limit of coating thickness must be set at 700 μm from the viewpoint of adherence performance and for preventing coat cracking after drying and coating material sagging during application. 
     For optimum coat performance and economy, the preferred range of coat thickness is 5 to 50 μm in combination with an inorganic binder and 5 to 100 μm in combination with an organic binder. 
     Moreover, with regard to the distribution of 0.05 to 5 μm grain diameter Zn alloy particles in the coating, corrosion resistance and rust prevention tend to improve when the content ratio of Zn alloy particles of a grain diameter of 0.05 to 5 μm in an outermost 10% thickness surface layer region of the dry film is high. In order to secure this corrosion resistance and rust prevention improving effect without fail, the content ratio of Zn alloy particles of a grain diameter of 0.05 to 5 μm in the outermost 10% thickness surface layer region of the dry film should be made twice or greater the content ratio of the Zn alloy particles of a grain diameter of 0.05 to 5 μm in the whole dry film. This markedly increases the high corrosion resistance and rust prevention effect of the coating film when it is applied to a steel. 
     EXAMPLES 
     Concrete embodiments of the present invention are explained in the following. 
     First Set of Examples 
     The grain-diameter distribution and average diameter of the Zn metal particles and Zn alloy particles, and the total volume percentage of particles in the 0.05 to 5 μm grain-diameter range were determined by laser scattering particle distribution analysis. 
     Therefore, grain diameter was evaluated as equivalent spherical diameter and volume percentage was evaluated as the equivalent spherical volume of the particles. 
     A histogram for evaluating grain diameter-distribution was drawn by representing grain diameters of 0.05 μm and greater on the horizontal axis and representing the proportion of the number of particles whose grain diameters fell in grain-diameter intervals d n  to d n+1  (μm) of 0.05 μm and greater diameter on the vertical axis. Here, d n +1=(1+α) d n , where n is a natural number and α is for convenience defined as 0.09 to 0.1. 
     The peak value was determined from this grain-diameter histogram. In the case where grain diameter is represented as equivalent spherical diameter and grain diameter is represented logarithmically, this method makes possible to draw a histogram that, for instance, has the 1 to 10 μm range divided into 25 to 27 equal grain diameter segments. 
     Specifically, the histogram was created by logarithmically representing grain diameter on the horizontal axis as equivalent spherical diameter, linearly representing in every equivalent spherical diameter segment of d n  to less than d n+1  on the vertical axis the frequency f n  of the particles contained in the segment as the equivalent spherical volume percentage (%) of the total equivalent spherical volume of all measured particles, plotting f n  for every (d n  d n+1 ) 1/2 , and connecting neighboring plots. 
     The peak value is therefore the grain diameter (d n  d n+1 ) 1/2  at which frequency f n  exhibits maximum value. 
     The grain-diameter distribution and average grain diameter of particles of 0.01 to 0.05 μm average diameter were determined by laser scattering particle distribution analysis using an analyzer equipped with an ultraviolet semiconductor laser. 
     As termed with respect to the present invention, “fine grains” means grains that, as determined by grain-diameter distribution measurement using laser scattering particle distribution analysis, are Zn metal particles or Zn alloy particles of 0.05 to 5 μm peak grain diameter or 0.01 to 5 μm average diameter having a grain-diameter frequency distribution with a single peak and a tail on either side of the peak. The term “coarse grains” means grains that are Zn metal particles or Zn alloy particles of 6 to 100 μm peak grain diameter or 6 to 100 μm average grain diameter having a grain-diameter frequency distribution with another single peak and a tail on either side of the peak. 
     Grain diameter distributions obtained in Examples are shown in Tables 1 to 172 as expressed in either peak grain diameter or average grain diameter. 
     The state of Zn metal particles and Zn alloy particles was determined by observing 50 to 100 randomly extracted particles using a scanning electron microscope equipped with a field emission electron gun. 
     Particle fragmentation (fracture) facets and cracked surfaces were observed with a scanning electron microscope. Zn alloy particles in particular were examined for Zn and Mg distribution state and the atomic concentration ratios of the elements by mapping analysis using an energy-dispersive X-ray analyzer attached to a scanning electron microscope. It was checked whether Zn—Mg intermetallic compounds were present and the element ratios of those found were examined. 
     Presence of Zn—Mg intermetallic compounds and their types were determined based on the shape of the secondary electron image, color and shape of the backscattered electron image, the mapping analysis image, the result of Zn and Mg atomic concentration ratio measurement, and result of Zn alloy particle X-ray diffraction analysis. 
     Specifically, Zn alloy particles for which presence of MgZn 2 , Mg 2 Zn 11  or Mg 2 Zn 3  was ascertained from the X-ray diffraction analysis results were measured with an energy-dispersive X-ray analyzer for physical fragmentation (fracture) facets on the surfaces of particles of 5 μm or greater grain diameter, MgZn 2 , Mg 2 Zn 11 , or Mg 2 Zn 3  was identified from the results of the Zn and Mg atomic concentration ratio measurement, and the shape and color thereof was ascertained from the secondary electron image and backscattered electron image of the surface thereof. 
     In the case of the surface of a fine particle of less than 5 μm grain diameter which, because of its small size, could not be accurately measured for element ratio with an energy-dispersive X-ray analyzer, presence of MgZn 2 , Mg 2 Zn 11  or Mg 2 Zn 3  was inferred by comparing the secondary electron image and backscattered electron image with the secondary electron image and backscattered electron image of a region other than a physical fragmentation face. 
     On the other hand, in the case of Zn alloy particles having an Mg concentration of 20 to 30 mass %, MgZn and Mg 7 Zn 3  were determined from the results of the atomic concentration ratio measurement. 
       FIG. 1  shows the grain-diameter distribution of Zn metal particles contained in a conventional zinc-rich primer, which can be considered to be typical of the Comparative Examples.  FIG. 2  shows the grain-diameter distribution of Zn metal particles contained in a highly corrosion-resistant, rust-prevention coating material typical of the present invention. 
     The grain-diameter distribution of the conventional zinc-rich primer shown in  FIG. 1  has a grain-diameter frequency peak at around 10 μm. In contrast, the grain-diameter distribution of the Invention Example shown in  FIG. 2 , while also having one grain-diameter frequency peak similar to that of the Comparative Example at around 10 μm, further has another grain-diameter frequency peak located 2 to 3 μm toward the fine-grain side from that of the Comparative Example. 
     In Comparative Examples 1 to 18 shown in Table 1, almost all of the particles are accounted for by spherical Zn metal particles of around 5 to 10 μm grain diameter produced by the mist processes. On the other hand, in all of the Invention Examples shown in Tables 2 to 5 and in Comparative Examples 19 to 49 shown in Tables 2 and 3, it can be seen that, with respect to the Zn metal particles and Zn alloy particles, the particles exhibiting two grain-diameter distributions had fragmentation (fracture) facets or cracks and were non-spherical, generally granular polyhedral particles of nearly spherical shape. 
     When the fragmentation (fracture) facets and cracked faces of the Zn alloy particles of the Invention Examples were observed as backscattered electron images, they were found to be divided into black regions with high Mg and white regions with low Mg content. An analysis of the black regions at the fragmentation faces and cracks of the particles of 5 μm or greater grain diameter revealed the presence of intermetallic compounds, chiefly of MgZn 2  and Mg 2 Zn 11  but in some cases Mg 2 Zn 3 , MgZn and Mg 7 Zn 3 . 
     Second Set of Examples 
     Coated test pieces were prepared as Comparative Examples and Invention Examples under the conditions indicated in Tables 1 to 172. The Comparative Examples are shown in Tables 1 to 5 and the Invention Examples in Tables 6 to 172. The coating materials of the respective examples were prepared by ordinary methods. In all Comparative Examples and Invention Examples of Tables 1 to 3, Tables 6 to 22, Tables 43 and 44, and Tables 79 and 80, two types were separately prepared using either a commercially available ethylene silicate resin inorganic binder or a commercially available urethane resin organic binder. 
     In the Examples of Tables 4 and 5, Tables 23 to 42, Tables 45 to 78, Tables 81 to 98, and Tables 99 to 172, various resins were used as binders and the type of resin used in each Example is indicated. 
     All coating materials had a moisture content of 0.8 mass % or less. The thicknesses of the dried coats are given in the Tables. 
     Corrosion resistance was assessed by conducting the salt spray test of JIS K 5600 (5% NaCl spray; 35° C.). Coating test pieces measuring 150×70×3.2 mm were used. The bottom of each test piece was formed with an X-cut using a cutter. The evaluation adopted in the corrosion test was time to occurrence of red rust from the test piece surface. The test results are shown in the tables. 
     When time to red rusting was less than 900 hours, corrosion resistance was rated Poor and designated by the symbol P in the tables. When time to red rusting was 900 hours to less than 2,000 hours, corrosion resistance was rated acceptable (Good) and designated by the symbol G in the tables. When time to red rusting was 2,000 hours or greater, corrosion resistance was rated particularly good within the acceptable range (Excellent) and designated by the symbol E in the tables. 
     In comparison with the Comparative Examples 1 to 30, the Invention Examples exhibited outstanding corrosion resistance as evidenced by marked suppression of red rusting. 
     Tables 43 to 78 show corrosion test results with presence/absence on the particle surfaces of Mg solid solution phase and Zn intermetallic compounds, and presence/absence of MgZn 2  or Mg 2 Zn 11 . 
     It can be seen from Tables 43 to 78 that presence of Mg solid solution phase and Zn—Mg intermetallic compounds on the particle surfaces inhibited red rusting and that red rusting was markedly inhibited when the intermetallic compounds were MgZn 2  and/or Mg 2 Zn 11  and in some cases MgZn 2 , Mg 2 Zn 11 , Mg 2 Zn 3 , MgZn and/or Mg 7 Zn 3 . 
     Tables 79 to 98 show the corrosion test results obtained when the ratio of all particles accounted for by Zn alloy particles of a grain diameter of 0.05 to 5 μm in an outermost 10% thickness surface layer region of the dry film was varied. 
     The ratio of Zn alloy particles of a grain diameter of 0.05 to 5 μm in the outermost 10% thickness surface layer region was varied by applying coating materials varied in the ratio of Zn alloy particles of a grain diameter of 0.05 to 5 μm at the final stage of the coating. 
     It can be seen from Tables 79 to 98 that red rusting was markedly inhibited when the ratio of all particles accounted for by Zn alloy particles of a grain diameter of 0.05 to 5 μm in the outermost 10% thickness surface layer region was twice or greater the ratio in the whole dry film. 
     Tables 99 to 172 relate to Invention Examples in which Zn metal particles comprising Zn and unavoidable impurities and having a grain-diameter distribution whose peak grain diameter or average grain diameter was 2 to 50 μm were later added to and mixed with fine-grain Zn metal particles and coarse-grain Zn metal particles, or fine-grain Zn alloy particles and coarse-grain Zn alloy particles of Invention Examples, the mixed particles were used to prepare highly corrosion-resistant, rust-prevention coating materials, and the prepared coating materials were applied to steels and dried. The tables show the results of corrosion tests conducted on the so-prepared coated steels. 
     The results of the evaluation are shown in the Corrosion Test Results column. When time to red rusting was less than 900 hours, corrosion resistance was rated Poor and designated by the symbol P. When time to red rusting was 900 hours to less than 2,000 hours, corrosion resistance was rated acceptable (Good) and designated by the symbol G in the tables. When time to red rusting was 2,000 hours or greater, corrosion resistance was rated particularly good within the acceptable range (Excellent) and designated by the symbol E in the tables. 
     It can be seen from Tables 99 to 172 that when the coating material was prepared from Zn alloy particles having a grain-diameter distribution with two (fine particle and coarse particle) peaks and Zn metal particles having a grain-diameter distribution with only one peak falling between those of the fine particles and coarse particles, excellent corrosion resistance was exhibited in the case where the ratio, in mass % based on the dry coating film, of (Zn alloy particle content %):(Zn metal particle content %) was, expressed as 1/x, such that x was 300.0 or less. 
     It can also be seen that corrosion resistance was excellent even when Zn metal particles of 2 to 50 μm average grain diameter were later added to the fine-grain Zn metal particles and coarse-grain Zn metal particles.

     INDUSTRIAL APPLICABILITY 
     As explained in the foregoing, the present invention enables provision of highly corrosion-resistant coating material and highly corrosion-resistant steel that exhibit excellent corrosion-resistance and rust prevention unattainable using the metal particles added to conventional rust-prevention coating materials. It achieves this improvement over the prior art by producing Zn metal particles or Zn alloy particles having two grain-diameter frequency peaks in the grain-diameter frequency distribution and combining the particles with an inorganic or organic binder. 
     The present invention therefore can therefore be advantageously applied for primary rust proofing or combating corrosion of steel materials used in industrial machinery, vehicles, ships, chemical industry facilities, buildings, bridges and the like. As such, it has considerable industrial applicability.
