Abstract

The invention discloses anti-fingerprint ultraviolet curing high-gloss varnish. The high-gloss varnish is prepared from, by weight, 8-13% of nine-degree-of-functionality urethane acrylate, 3-16% of organic silicon modified acrylate polymer, 6-13% of epoxy acrylate resin, 3-18% of trimethylolpropane acrylate, 2-5% of dipropylene glycol 2-propenyl ester or hexanediol diacrylate, 1-5% of 2-phenoxyethyl acrylate, 1-5% of photoinitiator, 1-2% of an anti-fouling auxiliary, 0.1-0.15% of an anti-shrinkage-cavity auxiliary, 15-25% of ethyl acetate and the balance propylene glycol methyl ether acetate. The high-gloss varnish can further enrich selections of ultraviolet curing painting in coating of automobiles or mobile phones or other plastic shells, anti-fingerprint performance and dirt resistance of similar products are greatly improved, requirements of high-grade automobiles or electronic product shells are met, and good economic benefits can be generated.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anti-fingerprint ultraviolet light curing high-gloss varnish. Background technique [0002] UV-curable coatings have the advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good coating performance after curing, and are suitable for high-speed automatic production. Therefore, in recent years, the output of UV-cured coatings With rapid growth, the application rate and amount of coating on the surface of plastic products, such as automotive interiors, mobile phones, computers and other consumer goods, are also increasing. [0003] However, with the development of society and the higher and higher requirements of consumers, the performance and appearance requirements of coatings are also increasing. For a long time, the anti-fingerprint effect of UV paint has been the quality goal pursued by the industry, and UV The anti-fing...
