Problems solved by technology

However, the hardness of the existing scratch-resistant coatings on the market is generally lower than 2H
Some scratch-resistant coatings have a hardness higher than 2H, but their transparency is not high, and they do not have the function of anti-ultraviolet rays, so they are not suitable for the requirements of window films and protective films for optical display products.

Abstract

The invention discloses a scratch-resistant ultraviolet coating for screen protection films. The coating is prepared by using the following raw materials, by weight, 0.7-1.5 parts of acrylate, 3.5-5 parts of saturated polyester resin, 2.3-4.4 parts of a platinum complex solution, 2-5 parts of isocyanato ethyl methacrylate, 3.4-6.6 parts of titanium dioxide, 2.6-3.8 parts of methylisobutylketone, 1.5-2.5 parts of vinyl chloride, 5.8-7.8 parts of water and 0.12-0.55 parts of a surfactant. The scratch-resistant ultraviolet coating for screen protection films is a good scratch-resistant ultraviolet-curable coating for window films and protection films, raw materials are convenient to draw, and the raw materials and the coating respectively have excellent stability, so the industrial popularization and application of the coating are convenient; the coating also has the characteristics of fast curing speed, simple preparation technology, and substantially reduced production cost; and a coat made by using the coating has the characteristics of moderate hardness, good transmittance and the like.

Description

technical field [0001] The invention relates to a coating, in particular to an ultraviolet scratch-resistant coating for a screen protective film, which belongs to the field of coatings. Background technique [0002] Scratch-resistant coating is a kind of thin-film coating, which has the characteristics of high hardness, wear resistance, and good light transmission. Film forming operation. Among them, the ultraviolet light curing method has the advantages of environmental protection, energy saving, and high efficiency. Scratch-resistant coatings are widely used in automotive solar film, automotive explosion-proof film, LCD display protective film, camera lens protective film, etc. However, the hardness of existing scratch-resistant coatings on the market is generally lower than 2H. Some scratch-resistant coatings have a hardness higher than 2H, but their transparency is not high, and they do not have the function of anti-ultraviolet rays, so they are not suitable for the ...
