Description of the invention: [Technical field to which the invention belongs] The present invention relates to a matte anion electroplating coating which is excellent in low temperature hardenability, coating film hardness, and mold impression concealment. [Prior art] Aluminum has so-called light weight, easy workability, and excellent corrosion resistance. It can be used in most materials, especially building materials, because of its properties. • The method of extruding aluminum is usually a method of heating and melting a cylindrical aluminum ingot, and then putting the molten material into an extruder to press it onto a mold having a hole with a predetermined cross-sectional shape. A method of sequentially passing through holes to obtain a profile with a predetermined formation. In addition, the corrosion resistance, abrasion resistance, and chemical resistance of aluminum materials are generally poor. Therefore, after the aluminum is anodized, a matte coating film is generally coated with the matte anion plating coating. However, in the case where the above-mentioned matte anion plating coating is electroplated on the aluminum profile after the anodizing treatment, the stamp of the aluminum profile of the material is easy to be displayed, so that there is a problem that the price of the product is low and deteriorated. In the past, in order to make it difficult to make such imprints obvious, there has been an invention of an anionic electroplating coating; it is a type of acrylic resin that has two different solubility parameters, and honey that is not compatible with their acrylic resins. Amine resin is formed by water dispersion. [Patent Literature 彳]. Another invention is a matte coating film containing a water-dispersible resin and a melamine resin, and obtained by the difference of the resin's SPS. [Patent Document 2]. 200536903 Since these inventions require firing above 1 70 ° C, not only the anodic oxide film is prone to cracks, the finishing and coating performance are reduced, and the energy consumption is increased, so it is also economically problematic. In other respects, when a coating material containing a hydroxyl group and a carboxyl group containing a resin and a blocked polyisocyanate compound is used, it is possible to obtain a hardenability with a gel fraction of 90% or more even if it is fired at 140 ° C, and High coating film hardness (pencil hardness of 4H or more), but low gloss (60 ° gloss of 10 or less), and the concealment of the impression is not sufficient [Patent Document 3]. φ In addition, regarding a part of the free isocyanate group of an ethylene-based copolymer having two or more free isocyanate groups in one molecule, the hydroxyl group in an acrylic resin having two or more hydroxyl groups in one molecule A part of the resin was reacted, and then all the remaining free isocyanate groups were reacted with a blocking agent to form an invention of a resin having a blocked isocyanate group and a hydroxyl group in one molecule [Patent Document 4]. When this invention is used only for a matte anion plating coating, a matte coating film having excellent low-temperature hardenability, coating film hardness, and mold impression concealability cannot be obtained. In addition, the mold of the matte coating film is excellent in the concealment of the imprint. [Patent Document 1] Japanese Patent Application Laid-Open No. 0-46065 [Patent Literature 2] Japanese Patent Application Laid-Open No. 2001-1-1 494 [Patent Literature 3] Japanese Patent Application Laid-Open No. 8-41 380 [Patent Literature 4] Japanese Patent Laid-Open No. 5-2471 [Disclosure of the Invention] [Summary of the Invention] [Problems to be Solved by the Invention] The problem to be solved is to find a matting anionic electroplating coating with excellent low-temperature hardenability, hard coating film 200536903 degrees, and excellent impression concealment. [Means to solve the problem] In order to solve the above-mentioned problems, the inventors deliberately and repeatedly conducted research, and found that by using one kind of ethylene having two or more free isocyanate groups in one molecule, A part of the free isocyanate group of the copolymer (a 1) reacts with a part of the hydroxyl group of the ethylene-based copolymer (a2) having a hydroxyl group, a carboxyl group, and an alkoxysilyl group, and then all the remaining Matte anion electroplating coating formed by the reaction of free isocyanate groups with a blocking agent and having a block isocyanate group and a hydroxyl group in the molecule (A) and a hardening catalyst (B). That is, the present invention has been completed. That is, the present invention is: 1. A matte anion plating coating characterized by using the free isocyanate group of an ethylene-based copolymer (a 1) having two or more free isocyanate groups in one molecule. Partly reacts with a part of the hydroxyl group of the ethylene-based copolymer (a2) having a hydroxyl group, a carboxyl group, and an alkoxysilyl group, and then reacts all the remaining free isocyanate groups with a blocking agent.

For forming a coating film using the matte anion plating coating of the present invention, the anion plating coating obtained as described above can be made into a bath, and the aluminum material is immersed in the bath, and a colored or uncolored anodized aluminum material is used as the bath. The object to be coated is anion-plated so that the thickness of the dry film formed is about 5 to 30 microns. Non-rinse or rinse is performed, and then set at room temperature. Bake at 150 ° C, preferably 80 ~ 14CTC-20-20200536903 for about 20 ~ 40 minutes, and dry to form a coating film. The coating film hardness of the coating material obtained by the application of the matte anion plating coating is a high coating film showing a pencil hardness of 4 Η or more (Note 3) and a TUKON hardness of 4 or more (Note 4). hardness. (Note 3) The hardness of the pencil is based on JIS KK 5600-5-4. Make the pencil lead touch the test coated surface at an angle of about 45 °. While pressing the test coated surface with a strength that will not damage the lead, the uniformity is uniform. At a speed of about 10 mm. This operation was repeated 5 times while changing the test location. The hardest pencil hardness mark was used as the pencil hardness. (Note 4) TUKON hardness: The coated plate was placed in a 2CTC constant temperature room for 4 hours, and then measured with a TUKON microhardness tester made by American Chain & Cable Co., Ltd. In addition, the matte anion plating coating can be easily adjusted in the degree of matting by using at least two types of emulsions in combination. For example, an ethylene-based copolymer (a 1) / ethylene-based copolymer (a2) containing 100 parts by weight based on the total amount of the ethylene-based copolymer (a 1) and the ethylene-based copolymer (a2) can be used. = 30 to 90 parts by weight / 10 to 70 parts by weight of the blending ratio, and the ethylene-based copolymer (a 1) / ethylene-based copolymer (a2) constituted by water dispersion = 30 to 90 parts by weight / 10 to 70 Anionic plating coating of emulsion (2) in the range of parts by weight. For example, in the case of a coating line, when it is desired to obtain a coating article with a varying degree of matting, the supply of anions can be adjusted in a timely manner by changing the blending ratio of the emulsion (1) / emulsion (2).
