Abstract

The invention discloses low-energy UV gloss oil for plastics. The UV gloss oil is prepared from the following components in percentage by weight: 50-60 percent of bifunctional urethane acrylate, 10-20 percent of tetra-functional urethane acrylate, 0.5-1 percent of a flatting agent, 2-4 percent of methyl benzoylformate, 0.5-1.5 percent of Irgacure 784, 1-3 percent of 184, 15-25 percent of tri-functional acrylate monomer and 8-15 percent of hexa-functional acrylate monomer. The invention further discloses a method for preparing the low-energy UV gloss oil for plastics. The UV gloss oil is used for plastic products; compared with existing UV gloss oil, the gloss oil has the advantages that energy for curing is relatively low, the gloss oil can be completely cured by 100-200mj / cm<2>, energy can be saved, and production cost can be reduced.

Description

technical field [0001] The invention relates to the UV field, in particular to a low-energy UV varnish for plastics and a preparation method thereof. Background technique [0002] UV varnish is a kind of transparent coating, also known as UV varnish. Its function is that after spraying or rolling coating on the surface of the substrate, it is irradiated by UV lamps to convert it from liquid to solid, and then achieve surface hardening, which has the effect of scratch resistance and scratch resistance, and the surface looks bright, beautiful and textured. mellow. At present, the energy required for curing the existing UV varnish is relatively high, generally 400~800mj / cm 2 , UV ultraviolet light irradiation time up to 4~5s, resulting in a waste of resources and an increase in cost. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a low-energy UV varnish for plastics. The UV varnish is u...
