Abstract

A vacuum plating UV composite coating for TPU materials comprises primer paint and finish paint. The primer paint comprises modified epoxy acrylate, two-functionality aliphatic polyurethane acrylate, cellulose acetate butyrate, 1-hydroxycyclohexyl phenyl ketone, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, polydimethylsiloxane, ethyl ester, butyl ester and propylene glycol monomethyl ether by weight percentage; the finish paint comprises modified epoxy acrylate, two-functionality aliphatic polyurethane acrylate, cellulose acetate butyrate, 2-hydroxy ethyl methacrylate phosphate, 1-hydroxycyclohexyl phenyl ketone, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, 2,2-dimethoxy-2-phenylacetophenone, polydimethylsiloxane, ethyl ester and butyl ester. According to the vacuum plating UV composite coating for the TPU materials, excellent flex resistance property is achieved, after folding is conducted, the phenomena of cracking and coloring of a paint film and a coating do not occur, and the good recuperability is achieved.

Description

technical field [0001] The invention relates to a UV coating, in particular to a UV composite coating used for vacuum electroplating on a TPU material. Background technique [0002] UV curing coating is an energy-saving and environment-friendly coating. It has no or low VOC emission, energy saving, fast curing rate, high production efficiency, suitable for assembly line production, low curing temperature, suitable for coating heat-sensitive substrates, good friction resistance, solvent resistance and stain resistance And other excellent performance, can also be tailored according to the requirements of users to meet the diverse individual needs of the market. Light-curing vacuum coating is a new type of UV coating developed on the basis of light-curing plastic coatings. It combines two technologies of UV coating and vacuum coating to obtain a new surface decoration effect. The treated plastic surface is completely shimmering with metallic luster, showing noble metal quali...
