[0038] Difunctional acrylate monomer (SR368): 15%

[0039] UV initiator (1104): 3%

[0040] Organosiloxane type leveling agent (DEUCHEM-432): 3%

[0041] Degussa (LTW): 1%

[0042] Nano silica: 1.5%

[0043] Ethyl acetate: 10%

[0044] After mixing the above-mentioned components except ethyl acetate in a closed container, add ethyl acetate and mix evenly, spray on a 0.188mm PET film, dry in an oven at 50 degrees for 3 minutes, and Test after curing by high-pressure mercury lamp: the pencil hardness of the coated biaxially oriented PET film is 3H, and when observed with the naked eye under a yellow monochromatic light source, the rainbow pattern is significantly lower than that of the sample of the comparative example. The coated sample was wiped 20 times ...

Abstract

The invention provides an anti-light reflection ultraviolet light curing coating for plastic surfaces, which comprises urethane acrylate containing vinyl unsaturated groups, acrylate activated monomers containing vinyl unsaturated groups, UV initiators, additives and solvents and is characterized by also being added with nano-scale magnesium fluoride, silicon dioxide or titanium dioxide. The nano-scale magnesium fluoride, silicon dioxide or titanium dioxide is added into the curing coating component of the product of the invention, so that the prepared product has obvious effect on preventing light reflection of ultraviolet light. Compared with the product which is not added with nano-scale magnesium fluoride, silicon dioxide or titanium dioxide, by observation under a yellow monochromatic source by naked eyes, the rainbow patterns of the product of the invention are obviously reduced.

Description

technical field [0001] The invention relates to a coating composition for plastics, in particular to an anti-reflection ultraviolet curing coating composition for plastic surfaces, and belongs to the field of coatings for plastics. Background technique [0002] With the rapid development of plastic film products in the world, companies are actively committed to the research and development and promotion of special performance plastic films, and new functional plastic films are constantly being applied to various fields of production, life and consumption. Japan's Sumitomo Bakelite, Toray, Dongshan, General Electric (GE) in the United States, and SKC (Sunkyong) in South Korea all have some unique functional plastic film products. The development of special plastic films with independent intellectual property rights according to special purposes has become the only way for the development of the plastics industry. The coating on the surface of plastic film is an important way...
