有机树脂在后述的热熔合过程中形成热熔合层，其夹在电工钢板之间，从而在电工钢板之间赋予粘合力。
The organic resin forms a thermally-bonded layer in thermosetting, and is disposed between electrical steel sheets to apply adherence between the electrical steel sheets.
热熔合层在电工钢板之间不能赋予适当的粘合力时，精确地层压的多个电工钢板在工艺进行过程中会发生错位。
When the thermally-bonded layer does not sufficiently apply adherence between the electrical steel sheets, a plurality of electrical steel sheets that are precisely stacked are misaligned during the process.
如果层压位置发生错位，则会影响最终电工钢板产品的质量。
When the lamination position is shifted, the quality of the final manufactured electrical steel sheet product is adversely affected.
对有机树脂进行热熔合之后能够确保粘合力，从而层压的电工钢板的位置不会发生错位。
Since adherence is assured after the thermosetting by the organic resin, the misalignment of the stacked electrical steel sheets can be prevented.
在后述的消除应力退火步骤中，有机树脂部分分解或部分残留，从而在电工钢板之间赋予粘合力。
The organic resin is partially decomposed in a stress relief annealing process, which will be described later, but partially remains thereby applying adherence between the electrical steel sheets.
此时，有机树脂可包括芳烃。
In this case, the organic resin may include an aromatic hydrocarbon.
此时，芳烃在高温下也不分解，因此在消除应力退火工艺之后仍能够保持粘合力。
In this case, the aromatic hydrocarbon is not pyrolyzed even at a high temperature, and thus maintains adherence even after the stress relief annealing process.
包含芳烃的有机树脂是指主链和/或侧链上包含芳烃的树脂。
The organic resin containing aromatic hydrocarbon implies a resin that contains an aromatic hydrocarbon in the main chain and/or side chain.
具体地，芳烃可包含选自苯、甲苯、二甲苯、萘、蒽及苯并芘中至少一种的官能团。
Specifically, the aromatic hydrocarbon may include at least one selected from benzene, toluene, xylene, naphthalene, anthracene, and benzopyrene as a functional group.
有机树脂具体可包括选自环氧类树脂、酯类树脂、丙烯酸酯类树脂、苯乙烯类树脂、聚氨酯类树脂及乙烯类树脂中的至少一种。
Specifically, the organic resin may include at least one selected from an epoxy resin, an ester resin, an acryl-based resin, a styrene resin, a urethane-based resin, and an ethylene resin.
此时，可选择前面例举的树脂中至少一种或者至少两种的混合物，从而改善热熔合层、粘合层的耐热性。
In this case, by selecting one or more mixtures among the resins exemplified above, it is possible to improve heat resistance of the thermally-bonded layer and the adhesive layer.
换而言之，有机树脂有助于热熔合层、粘合层的绝缘性、耐热性、表面特性等。
That is, the organic resin contributes to improving insulating properties, heat resistance, and surface characteristics of the thermally-bonded layer and the adhesive layer.
有机树脂的重量平均分子量可以为1000至100000，数均分子量可以为1000至40000。
The organic resin may have a weight-average molecular weight of 1000 to 100,000 and a number average molecular weight of 1000 to 40,000.
对于重量平均分子量和数均分子量而言，如果小于各下限，则固化性、强度等粘合涂层的物性会下降，如果大于各上限，则有机树脂内会发生相(phase)分离，从而使与金属磷酸盐的相溶性下降。
When each of the weight-average molecular weight and the number average molecular weight is below the lower limit, properties of the adhesive coating layer, such as curability and strength, may be deteriorated, and when the upper limit is exceeded, phase separation in the organic resin may occur and compatibility with a metal phosphate may be deteriorated.
更为具体地，有机树脂可具有5000至30000的重量平均分子量。
More specifically, the organic resin may have a weight-average molecular weight of 5000 to 30,000.
此外，水溶性树脂的软化点(Tg)可为30至150℃，固体分数(固体成分的含量)可为10至50重量％。
In addition, a softening point (Tg) of a water soluble resin may be 30 to 150 °C, and a solid fraction (contents of solid) may be 10 to 50 wt%.
只是，当水溶性树脂的软化点(Tg)超过120℃时，组合物的粘度过高，会导致涂覆操作性变差。
When the softening point (Tg) of the water soluble resin exceeds 120 °C, viscosity of the composition becomes too high and thus coating workability may be deteriorated.
第一组合物中可包含10至80重量％的有机树脂。
The organic resin may be included at 10 to 80 wt% of the first composition.
当有机树脂的含量过少时，无法确保适当的热熔合层的粘合力。
When the amount of the organic resin is too small, adherence of the thermally-bonded layer cannot be sufficiently assured.
当有机树脂的含量过多时，由于在消除应力退火步骤中部分有机树脂发生分解，因此无法确保适当的粘合层的粘合力。
When the amount of the organic resin is too large, adherence of the adhesive layer cannot be sufficiently assured because the organic resin is partially pyrolyzed during the stress relief annealing process.
更具体地，第一组合物中可包含20至70重量％的有机树脂。
More specifically, the organic resin may be included at 20 to 70 wt% of the first composition.
第一组合物包含有无机纳米粒子被取代到的有机树脂中的有/无机复合体。
The first composition includes an organic/inorganic composite in which inorganic nanoparticles are substituted for an organic resin.
如上所述，由于在消除应力退火步骤中部分有机树脂发生分解，因此仅靠有机树脂很难确保适当的粘合层的粘合力。
As previously described, in the stress relief annealing process, the organic resin is partially pyrolyzed, and thus it is difficult to assure sufficient adherence of the adhesive layer only with the organic resin.
为了赋予适当的粘合层的粘合力，应包含有无机纳米粒子被取代到有机树脂中的有/无机复合体。
In order to provide appropriate adherence of the adhesive layer, an organic/inorganic composite in which inorganic nanoparticles are substituted for an organic resin is included.
无机纳米粒子在消除应力退火步骤之后将赋予粘合层的粘合力。
After the stress relief annealing process, the inorganic nanoparticles provide adherence to the adhesive layer.
另外，可防止金属磷酸盐的沉淀(precipitation)或者粘结(agglomeration)现象，并且有助于消除应力退火(Stress relief Annealing)之后更好地显现出表面特性。
In addition, precipitation or agglomeration of the metal phosphate can be prevented, and surface characteristics after the stress relief annealing can be excellently exhibited.
有/无机复合体中对有机树脂的说明与前面所述的有机树脂的说明相同，因此省略其详细说明。
In the organic/inorganic compound, the organic resin is the same as the above-described organic resin, so duplicated descriptions will be omitted.
前面所述的第一组合物的有机树脂与有/无机复合体中的有机树脂可为相同的种类。
The organic resin of the above-stated first composition and the organic resin of the organic/inorganic compound may be the same type.
当单独添加无机纳米粒子而不是被取代到有机树脂中时，无机纳米粒子间将发生凝聚而不能分散。
When the inorganic nanoparticles are not replaced with an organic resin, and are added alone, the inorganic nano particles aggregate with each other and dispersion does not occur.
具体地，无机纳米粒子可包含SiO2、Al2O3、TiO2、MgO、ZnO、CaO、及ZrO2中至少一种。
Specifically, the inorganic nanoparticles may include at least one of SiO2, Al2O3, TiO2, MgO, ZnO, CaO, and ZrO2.
无机纳米粒子的平均粒子尺寸可为5至100nm。
The inorganic nanoparticles may have an average particle size of 5 to 100 nm.
当无机纳米粒子的尺寸过小时，很难制成有/无机复合体，当过大时，会降低相溶性。
When the size of the inorganic nanoparticles is too small, it is difficult to manufacture an organic/inorganic compound, and when it is too large, compatibility may decrease.
有/无机复合体内5至60重量％会被无机纳米粒子取代。
The inorganic nanoparticles may be substituted in an amount of 5 to 60 wt% in the organic/inorganic compound.
即，有/无机复合体100重量％内可包含5至60重量％的无机纳米粒子及40至95重量％的有机树脂。
That is, the inorganic nanoparticles at 5 to 60 wt% and the organic resin at 40 to 95 wt% may be included with respect to 100 wt% of the organic/inorganic compound.
当无机纳米粒子的含量过少时，在消除应力退火之后将很难确保适当的粘合层的粘合力。
When the amount of the inorganic nanoparticles is too small, appropriate adherence of the adhesive layer after the stress relief annealing cannot be assured.
当无机纳米粒子的含量过多时，会引发无机纳米粒子凝聚的问题。
When the amount of the inorganic nanoparticles is too large, agglomeration of the inorganic nanoparticles may occur.
第一组合物中可包含20至90重量％的有/无机复合体。
The organic/inorganic compound at 20 to 90 wt% may be included in the first composition.
当有/无机复合体含量过少时，消除应力退火之后会很难确保适当的粘合层的粘合力。
When the amount of the organic/inorganic nano compound is too small, appropriate adherence of the adhesive layer after the stress relief annealing cannot be assured.
此外，会引发金属磷酸盐的沉淀(precipitation)或者粘结(agglomeration)现象。
In addition, precipitation or agglomeration of the metal phosphate may occur.
当有/无机复合体含量过多时，有机树脂的含量相对下降，从而很难确保适当的热熔合层的粘合力。
When the amount of the organic/inorganic compound is too large, the content of the organic resin is relatively reduced such that it is difficult to assure appropriate adherence of the thermally-bonded layer.
更具体地，第一组合物中可包含30至80重量％的有机树脂。
More specifically, the organic resin at 30 to 80 wt% may be contained in the first composition.
电工钢板粘合涂覆组合物以总固体100重量％为基准，可包含15至70重量％的第一组合物。
15 to 70 wt% of the first composition may be included on the basis of 100 wt% of the total solids of the electrical steel sheet adhesive coating composition.
当第一组合物的含量过少时，很难确保适当的热熔合层及消除应力退火之后的粘合层的粘合力。
When the content of the first composition is too small, appropriate adherence of the thermally-bonded layer and the adhesive layer after the stress relief annealing cannot be assured.
当第一组合物的含量过多时，第二组合物的含量相对减少，会引发无法适当地确保粘合层的粘合力的问题。
When the amount of the first composition is too large, the content of the second composition is relatively reduced such that it is difficult to assure appropriate adherence of the adhesive layer.
更具体地，可包含20至60重量％的第一组合物。
More specifically, the first composition at 20 to 60 wt% may be included.
第二组合物可包含金属磷酸盐和磷酸。
The second composition includes a metal phosphate and phosphoric acid.
本发明的一实施例中使用的金属磷酸盐可通过磷酸(H3PO4)与金属氢氧化物(Mx(OH)y)或者金属氧化物(MxO)的反应来制备，具体示例为后述实施例中使用的第一磷酸铝(Al(H3PO4)3)、第一磷酸钴(Co(H3PO4)2)、第一磷酸钙(Ca(H3PO4)2)、第一磷酸锌(Zn(H3PO4)2)、第一磷酸镁(Mg(H3PO4)2)等。
The metal phosphate used in the exemplary embodiment of the present invention may be prepared by using a reaction of phosphoric acid (H3PO4) and a metal hydroxide (Mx(OH)y) or a metal oxide (MxO), and specifically, aluminum phosphate monobasic (Al(H3PO4)3), cobalt phosphate monobasic (Co(H3PO4)2), calcium phosphate monobasic (Ca(H3PO4)2), zinc phosphate monobasic (Zn(H3PO4)2), magnesium phosphate monobasic (Mg(H3PO4)2), and the like.
复合金属磷酸盐有助于基于热熔合的热熔合层的高温粘合性、高温耐油性以及消除应力退火之后的粘合特性。
The metal phosphate contributes to the adhesive characteristics of the adhesive layer after high temperature adhesion, high temperature oil resistance, and stress relief annealing of the thermally-bonded layer by heat fusion.
由于与前述的包括烃的树脂及有机/无机复合体气体一起包含，所以粘合涂覆组合物成为有机/无机混合组分物。
Since it is included together with the above-described resin containing hydrocarbons and the organic/inorganic compound, the adhesive coating composition becomes an organic/inorganic mixed composition.
前面虽简单提及过，但是金属磷酸盐由Mx(H3PO4)y的化学式表示，所述第二成分中可包含至少一种或者两种该金属磷酸盐的混合物。
As briefly mentioned above, the metal phosphate is represented by a chemical formula of Mx(H3PO4)y, and a mixture of one or more metal phosphates may be included in the second component.
前面虽简单提及过，但是第二组合物中包含的金属磷酸盐可通过金属氢氧化物(Mx(OH)y)或者金属氧化物(MxO)与磷酸(H3PO4)的反应来制备。
As briefly mentioned above, the metal phosphate included in the second composition may be prepared by a reaction of a metal hydroxide (Mx(OH)y) or metal oxide (MxO) and phosphoric acid (H3PO4).
例如，将以包含85重量％的自由磷酸磷酸(H3PO4)的磷酸水溶液100重量份为基准，分别投入金属氢氧化物(Mx(OH)y)或者金属氧化物(MxO)，在80至90℃下反应6至10小时，即可获得各金属磷酸盐。
For example, based on 100 parts by weight of a phosphoric acid aqueous solution containing 85 wt% phosphoric acid (H3PO4), a metal hydroxide (Mx(OH)y) or metal oxide (MxO) was respectively added and reacted at 80 to 90 °C for 6 to 10 hours, such that each metal phosphate can be obtained.
此时，金属氢氧化物(Mx(OH)y)或者金属氧化物(MxO)的投入量分别以所述磷酸水溶液100重量份为基准，氢氧化铝(Al(OH)3)为1至40重量份，氢氧化钴(Co(OH)2)为1至10重量份，氧化钙(CaO)为1至15重量份，氧化锌(ZnO)为1至20重量份，氧化镁(MgO)为1至10重量份。
In this case, the amount of input of the metal hydroxide (Mx(OH)y) or metal oxide (MxO) is 1 to 40 parts by weight for aluminum hydroxide (Al(OH)3), 1 to 10 parts by weight for cobalt hydroxide (Co(OH)2), 1 to 15 parts by weight for calcium oxide (CaO), 1 to 20 parts by weight parts for zinc oxide (ZnO), and 1 to 10 parts by weight for magnesium oxide (MgO), respectively, on the basis of 100 parts by weight of the phosphoric acid aqueous solution.
当分别满足所述范围时，能够保持耐热性和/或粘合性的均衡。
When such a range is satisfied, heat resistance and/or adherence can be balanced.
以第二组合物100重量％为基准，可包含10至80重量％的金属磷酸盐。
The metal phosphate may be included at 10 to 80 wt% based on 100 wt% of the second composition.
当金属磷酸盐含量过少时，消除应力退火之后会很难确保适当的粘合层的粘合力。
When the content of the metal phosphate is too small, adherence of the adhesive layer after stress relief annealing cannot be sufficiently assured.
当金属磷酸盐的含量过多时，由于金属磷酸盐之间发生凝聚，粘合层的粘合力反而会变差。
When the content of the metal phosphate is too large, adherence of the adhesive layer may be deteriorated due to agglomeration of the metal phosphate.
磷酸与前述金属磷酸盐一起有助于基于热熔合的热熔合层的高温粘合性、高温耐油性及消除应力退火(Stress Relief Annealing)之后粘合层的粘合特性。
The phosphoric acid together with the metal phosphate described above contributes to the adhesive characteristic of the adhesive layer after high temperature adhesion, and high temperature oil resistance and stress relief annealing of the thermally-bonded layer by heat fusion.
以第二组合物100重量％为基准，可包含20至90重量％的磷酸。
Phosphoric acid may be included at 20 to 90 wt% based on 100 wt% of the second composition.
当磷酸的含量过少时，消除应力退火之后会很难确保适当的粘合层的粘合力。
When too little of the phosphoric acid is included, it may be difficult to properly secure adherence of the adhesive layer after stress relief annealing.
磷酸具有吸水性质，因此当磷酸的含量过多时，将吸收粘合涂覆组合物中的水分，从而使粘合涂覆组合物凝聚。
Since phosphoric acid has the property of absorbing moisture, when too much of the phosphoric acid is contained, it can absorb moisture in the adhesive coating composition, thereby causing agglomeration of the adhesive coating composition.
因此，粘合层的粘合力反而会变差。
Due to this, adherence of the adhesive layer may be deteriorated.
更具体地，以第二组合物100重量％为基准，可包含30至70重量％的磷酸。
More specifically, the phosphoric acid may be included at 30 to 70 wt% based on 100 wt% of the second composition.
以电工钢板粘合涂覆组合物总固体100重量％为基准，可包含20至80重量％的第二组合物。
The second composition may be included at 20 to 80 wt% based on 100 wt% of total solids of the electrical steel sheet adhesive coating composition.
当第二组合物的含量过少时，会发生消除应力退火之后很难适当地确保粘合层的粘合力的问题。
When the content of the second composition is too small, after stress relief annealing, a problem in which adherence of the adhesive layer cannot be sufficiently secured may occur.
