Abstract

The invention provides waterborne UV (ultraviolet)-cure vacuum electroplating primer paint and a preparation method for the same, and belongs to the field of chemical coating. The waterborne UV-cure vacuum electroplating primer paint which is coating mainly comprises, by weight, 30-70 parts of waterborne polyurethane dispersion, 30-70 parts of waterborne UV dispersion, 2-15 parts of cosolvents, 0.2-1.5 parts of wetting agents, 1-6 parts of photoinitiators, 2-20 parts of water and an appropriate quantity of pigment. The waterborne UV-cure vacuum electroplating primer paint and the preparation method have the advantages that the difficult problem of poor adhesion between existing primer paint and existing finish paint can be solved by the aid of the waterborne UV-cure vacuum electroplating primer paint which is intermediate coat prepared by the aid of the preparation method; plating is colored and is ultimately protected by finish paint, and accordingly durable metal decoration effects can be realized; paint films formed by the aid of a method are excellent in adhesion, abrasion resistance, alcohol resistance, perspiration resistance and storage stability.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and in particular relates to a water-based UV-curable vacuum electroplating color-adding intermediate paint; in addition, the invention also relates to a preparation method and an electroplating method of the water-based UV-curable vacuum electroplating color-adding intermediate paint. Background technique [0002] UV vacuum electroplating coating is a new type of ultraviolet curing coating developed on the basis of UV plastic coating. The metal vacuum plating process is a process in which the coating material is vaporized by a specific heating source in a high vacuum environment, and then deposited on the surface of the workpiece to achieve a metal effect. According to the form of the heating source, it is divided into vacuum evaporation plating and vacuum magnetron sputtering. shot coating. Due to the lack of smoothness of the surface of general engineering plastics, a primer is needed to coat...
