Problems solved by technology

The existing metal coatings are mainly solvent-based baking coatings, which have the advantages of good adhesion, good flexibility, high temperature resistance and no yellowing, etc. However, the solvent-based baking coatings contain a large amount of organic solvents. After these organic solvents volatilize and enter the atmosphere, they not only cause harm to human health, but also cause serious environmental pollution. Moreover, this type of solvent coatin

Abstract

The invention discloses metal coating and a preparation process thereof. The metal coating is prepared from acrylic resin, amino resin, propylene glycol methyl ether acetate, polysiloxane, polyxyethylated alkylphenol, polydimethylsiloxane, ethylene bistearic amide, pigments, filler, potassium hydroxide, benzotriazole, melamine, 12-oxystearic acid, methyl methacrylate, lauryl sodium sulfate, tert-amylphenol, tetraethylammonium tetrafluoroborate, benzyltriphenyl phosphonium chloride, trifluoroacetylacetone, dibromomethane, aluminum powder, zinc powder, deionized water, cosolvent and additives. The preparation process includes aluminum powder and zinc powder preparation, composition A preparation, composition B preparation and composition compounding. The metal coating is stable in using effect, high in corrosion resistance, safe and nontoxic to human bodies, energy efficient and environmental friendly. The preparation method is simple and feasible in operation, and environmental friendliness and low consumption in preparation and low cost are realized.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a metal coating and a preparation process thereof. Background technique [0002] In recent years, with the continuous application of metal products in new industries, in order to enhance the weather resistance and corrosion resistance of metal products, prolong the service life of metal products and increase their aesthetics, it is necessary to process the surface of metal materials Treatment, such as electroplating, electroless plating, coating technology, etc. Metal aluminum, especially aluminum foil or aluminum film deposited on plastic or paper is soft in texture and poor in wear resistance and scratch resistance. Aluminum alloy profiles also have similar problems and need to be protected by coating. Similar to traditional paint painting, before metal painting, most of the metal surfaces need to be pretreated in some form to improve the surface condition, so as to improve t...
