Title: Coating structure and method thereof of radiation-resistant adhesive

Description:
(a) TECHNICAL FIELD OF THE INVENTION 
     The present invention provides a coating structure and the method thereof of the radiation-resistant adhesive having radiation-resistant, bonding, waterproof, crack resistance, and good elasticity. 
     (b) DESCRIPTION OF THE PRIOR ART 
     Lead has many negative effects on the human body, but there are many things in life that will add lead as a raw material for manufacturing. For example, in the manufacture of paint, many unscrupulous manufacturers add lead as a manufacturing material for paint, so there are many countries control and limit the amount of lead in the paint; and the earlier gasoline also contained a lot of lead, so after discovering the damage of lead to the human body in modern times, it gradually changed to unleaded gasoline. However, some places still use lead-containing items, such as the radiology room of the hospital. The radiology room of the hospital uses the lead-containing wall surface as a radiation-preventing faceplate to achieve the anti-radiation effect. However, due to the progress of the times, people pay more and more attention to health, so the lead-free wall surface of the radiology room also has an alternative item, that is, using a Barium-plate as a wall surface to block radiation. However, although the Barium-plate is harmless to the human body and can block radiation; it is necessary to use an adhesive with the radiation-blocking effect between the Barium-plates in order to have a complete anti-radiation function. 
     SUMMARY OF THE INVENTION 
     The main objectives of the invention is lied in that: The effects of bonding, waterproof, crack resistance, and good elasticity are produced via the colloid, and the radiation-resistant function is achieved by using the Barium sulfate at the same time. 
     In order to achieve the above objectives, the main structure of the present invention comprises: a radiation-resistant adhesive mixed with at least one colloid and at least one Barium sulfate defined at the side of the colloid, at least one Polydimethyloxane defined in the colloid, at least one Decane coupling agent defined in the colloid and located at the side of the Polydimethyloxane, and at least one gas-phase Silicon dioxide defined in the colloid and located at the side of the Decane coupling agent. 
     With the above structure, the user can use the radiation-resistant adhesive to bond the Barium-plates with each other and fill the gaps between the Barium-plates; and since the colloid is composed of Polydimethyloxane, Decane coupling agent, and gas-phase Silicon dioxide; it can produce the effects of bonding, waterproof, crack resistance, and good elasticity; and it can generate the function of radiation blocking via the Barium sulfate to achieve the anti-radiation effect. 
     With the above techniques, the present invention can break through the problem that the adhesive between the Barium-plates needs to have anti-radiation function; and so as to achieve the practicality and progressiveness with the above advantages.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following detailed description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. 
     The foregoing and other aspects, features, and utilities of the present invention will be best understood from the following detailed description of the preferred embodiments when read in conjunction with the accompanying drawings. 
     Please refer to  FIG. 1  to  FIG. 5 , which are the schematic block diagram of the structure to the schematic diagram of the wall surface of the preferred embodiment of the present invention; it will be apparent from the figures that the present invention comprises: a radiation-resistant adhesive  1  which is obtained by mixing a colloid  11  and a Barium sulfate  12  defined at the side of the colloid  11 , wherein the colloid  11  is a composed by a Polydimethyloxane  111 , a Decane coupling agent  112  defined at a side of the Polydimethyloxane  111 , and a gas-phase Silicon dioxide  113  defined at a side of the Decane coupling agent  112 ; thereby, the colloid  11  has a function similar to that of the Silicone; wherein the Barium sulfate  12  accounts for 65% to 75% by weight of the radiation-resistant adhesive  1 , the Polydimethyloxane  111  accounts for 24% to 34% by weight of the radiation-resistant adhesive  1 , the Decane coupling agent  112  accounts for 0.5% to 1% by weight of the radiation-resistant adhesive  1 , and the gas-phase Silicon dioxide  113  accounts for 0.5% to 1% by weight of the radiation-resistant adhesive  1 . 
     The method for using the radiation-resistant adhesive  1  of the present invention comprises the following steps:
         (a) Taking a plurality of Barium-plates;   (b) Bonding each of the Barium-plates with a radiation-resistant adhesive mixed by the colloid and the Barium sulfate to adhere with each other and fill the gaps between the Barium-plates;   (c) Each of the Barium-plats is bonded to each other by a bonding effect formed by the combination of the Polydimethyloxane, the Decane coupling agent, and the gas-phase Silicon dioxide in the colloid; and   (d) Cooperating with the Barium sulfate to form an anti-radiation faceplate after each of the Barium-plates is bonded.       

     As the steps described above, the user can use the radiation-resistant adhesive  1  to adhere the Barium-plates with each other and fill the gaps between the Barium-plates; and the colloid  11  is composed by mixing the Polydimethyloxane  111 , Decane coupling agent  112 , and the gas-phase Silicon dioxide  113 ; therefore, it can have a similar effect to the Silicone (Silicone is a paste having a bonding effect when stored, but after drying; it will form a state similar to the plastic having elasticity; so it can be used to bond many items; and it will have the effects of having elasticity, crack resistance, and waterproof after bonding.); therefore, the colloid  11  can also have the advantages of bonding, waterproof, crack resistance, and good elasticity at the same time; and by bonding each of the Barium-plates  2 , it can cooperate with the Barium sulfate  12  to achieve the function of blocking radiation, thereby having the anti-radiation function; therefore, the Barium-plate  2  can be combined with the radiation-resistant adhesive  1  to form a blocking faceplate in the radiology room. 
     Therefore, the technical key of the coating structure and the method thereof of the radiation-resistant adhesive of the present invention for improving the conventional technology is:
         1. Producing the advantages of bonding, waterproof, crack resistance, and good elasticity by the Polydimethyloxane  111 , the Decane coupling agent  112 , and the gas-phase Silicon dioxide  113  in the colloid  11 ; thereby sewing as the bonding agent between the Barium-plates  2 .   2. Producing the anti-radiation effect by the Barium sulfate  12 ; thereby cooperating with the Barium-plate to serve as an anti-radiation faceplate.
