Ultraviolet-curing gradient color electroplating intermediate paint

Abstract

The invention belongs to the field of coatings, and concretely relates to an ultraviolet-curing gradient color electroplating intermediate paint. The ultraviolet-curing gradient color electroplating intermediate paint comprises, by weight, 6-36 parts of solvent-type polyurethane acrylate, 3-29 parts of thermoplastic acrylate, 0.8-12 parts of a reactive diluent, 0.5-8 parts of a nanometer color paste, 0.2-5.5 parts of an initiator, 0.1-0.6 part of an assistant and 35-90 parts of a diluent. The ultraviolet-curing gradient color electroplating intermediate paint effectively improves the dyeing defect, color spots and metal texture of a metal coating layer and different gradient color effects of the same metal coating surface; a free radical photoinitiator and a cationic photoinitiator are compounded to ensure the curing speed by the free radical photoinitiator and ensure deep curing by the cationic photoinitiator; and thiol acrylate cooperates with polyether polyurethane acrylate, and thesynergistic action of the two components ensures the sufficient curing of a film and reduce the sensitivity of the surface of the film to gases, water steam and outside impurities, so the prepared film has good aging resistance.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an ultraviolet light-cured gradient color electroplating intermediate paint. Background technique [0002] With the development of plastic decoration technology, the metallized decoration technology of plastic products is produced. It uses the plastic substrate to coat the primer, vacuum electroplating, coats a layer of metal film, and then coats a layer with a gradient. The colored medium paint is formed by applying a layer of top coat. The painted plastic surface is completely shimmering with metallic luster, showing a noble and magnificent metal quality, and it cannot be seen as a plastic product at all. Metallized plastic decoration can not only save a lot of precious metal materials, but also greatly reduce the quality of products. In recent years, it has been widely used in the manufacture of cosmetic packaging bottles and boxes, automobile lights, mobile phone plastic ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the incomplete curing of the deep layer of the photocuring intermediate paint leads to the decline of the coating film performance, the invention discloses an ultraviolet light curing gradient color electroplating intermediate paint, which uses a compound of a free radical photoinitiator and a cationic photoinitiator as a photoinitiator. agent to solve the problem of deep curing of light-curing intermediate paint
