Abstract

The invention discloses anodic oxidation simulation coating and a method for preparing the same. The anodic oxidation simulation coating comprises, by weight, 75 parts of polyurethane acrylic resin, 80 parts of fluorocarbon resin, 1.5 parts of leveling agents, 4 parts of curing accelerators, 18 parts of electroplating silver paste, 3.7 parts of scratch-resistant auxiliaries and 28 parts of nanometer color paste. The method includes steps of stirring the polyurethane acrylic resin, leveling agent solvents and the electroplating silver paste according to preset proportions until the polyurethane acrylic resin, the leveling agent solvents and the electroplating silver paste are completely dissolved to obtain first mixtures; adding the fluorocarbon resin, the curing accelerators, the scratch-resistant auxiliaries and the nanometer color paste into the first mixtures and sufficiently stirring the fluorocarbon resin, the curing accelerators, the scratch-resistant auxiliaries, the nanometer color paste and the first mixtures to obtain second mixtures; spraying the second mixtures by the aid of spray guns, drying the second mixtures and the forming paint films on the surfaces of products. Anodic oxidation effects can be equivalently realized by the paint films. The anodic oxidation simulation coating and the method have the advantages that the anodic oxidation simulation coating is equivalent to coating with anodic oxidation texture and performance, the products are short in coloring time, the anodic oxidation simulation coating is stable in color difference between lots and is easy to operate, and the like.

Description

technical field [0001] The invention relates to a coating, in particular to an imitation anodic oxidation coating and a preparation method thereof. Background technique [0002] The existing anodic oxidation is to use metal or alloy parts as the anode, and use electrolysis to form an oxide film on the surface. The film layer has a large number of micropores with great adsorption capacity, which can absorb dyes and thus carry out coloring. , the technology has good corrosion resistance, wear resistance and texture. [0003] However, this method takes a long time, often tens of minutes, and the color of the coloring is affected by the coloring mechanism, the thickness of the oxide film, and the speed of electrolytic coloring, so it is difficult to control the batch consistency. Contents of the invention [0004] Aiming at the defects existing in the prior art, the present invention now provides an imitation anodic oxidation coating and its preparation method, which has the ...
