Abstract

The invention discloses frosted ultraviolet curing coating with high abrasion resistance. The frosted ultraviolet curing coating comprises, by weight, 20-30 parts of six-functionality urethane acrylate, 20-30 parts of four-functionality urethane acrylate, 8-15 parts of six-function acrylate monomers, 2-4 parts of auxiliaries, 1-5 parts of frosting powder, 20-30 parts of solvents and 2.0-3.0 parts of photoinitiators. The frosted ultraviolet curing coating has the advantages that the scratching resistance of the frosted ultraviolet curing coating can be greatly improved, and sand pattern results are uniformly distributed and are elegant and attractive; the performance of the traditional ultraviolet curing coating can be guaranteed, and the frosted ultraviolet curing coating has touch sense and textures of the sand pattern results.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high wear-resistant frosted ultraviolet light curing coating. Background technique [0002] Frosted UV-cured paint is a new type of paint. Its products are beautiful, elegant and generous, so it is popularized very quickly. In just a few years, it has occupied a considerable proportion in the fields of cigarette bags, wine bags, cosmetics, mobile phones, computers and other electronic products. However, since there is no unified detection and judgment standard for matte UV-curable coatings in China or even internationally, the products on the market generally have poor scratch resistance and are easy to bruise; the effect of sanding is not uniform, and the grain texture is poor. [0003] With the improvement of the level of UV curing coatings, the scratch resistance and wear resistance of frosted UV curing coatings are also increasing. The scratch resistance and wear resistance of the ...
