Abstract

The invention relates to an environment-friendly water-based imitating electrosilvering coating. The coating is prepared from, by weight, 4 to 5 parts of a water-based aluminum paste, 4 to 8 parts ofa coalescing agent, 30 to 50 parts of resin, 3 to 5 parts of a dispersing agent, 3 to 5 parts of an anti-settling agent, 2 to 3 parts of a thickening agent, 0.5 to 1 part of a pH regulator and 30 to 40 parts of deionized water. The preparation method comprises the steps of stirring, standing and dispersing. Compared with coatings in the prior art, the coating of the invention has the advantages oflow cost, strong metal feeling, excellent adhesion to plastic parts, good water resistance, excellent film coating performance, reduction of VOC emission and the like.

Description

technical field [0001] The invention relates to the field of interior and exterior coatings for automobiles, in particular to an environment-friendly water-based imitation electroplating silver coating and a preparation method thereof. Background technique [0002] At present, due to the poor weather resistance, short service life and mediocre decorative effect of plastic parts, most of the plastic products of interior and exterior parts of automobiles need surface treatment, while traditional electroplating parts are costly and pollute seriously. [0003] At present, there are solvent-based imitation electroplating silver coatings using organic solvents to replace the electroplating process, which have low cost and good performance. For example, patent CN 103319966A discloses an environment-friendly electroplating silver paint. It is composed of modified acrylic resin, aluminum silver paste, ethyl acetate, butyl acetate, propylene glycol methyl ether acetate and leveling a...
