High-wear-resistance and low-flash-point anti-glare film and preparation method thereof

Abstract

The invention discloses a high-wear-resistance and low-flash-point anti-glare film and a preparation method thereof. The preparation method comprises the steps that S1, mixing the following componentsby weight percentage: 15%-70% of an acrylate prepolymer, 5%-40% of an acrylate monomer, 0.5%-10% of anti-glare particles, 1%-6% of a photoinitiator, 0.1%-0.5% of a dispersing agent, 0.1%-0.5% of a leveling agent, 0.1%-0.6% of a fluorine-containing auxiliary agent, and 20%-75% of a solvent; and S2, coating a base material with the anti-dazzle coating liquid, baking and drying, and carrying out UVcuring to obtain the anti-glare film with high wear resistance and low flash point. The anti-glare film provided by the invention has excellent properties of low flash point and high definition, and also has excellent wear resistance.

Description

technical field [0001] The invention relates to the technical field of anti-glare films, in particular to an anti-glare film with high wear resistance and low flash point and a preparation method thereof. Background technique [0002] With the rapid development of the electronic information industry, various portable electronic terminals and electronic products, such as mobile phones, computers, conference electronic tablets, etc., have become extremely popular, bringing great convenience to people's work and life. But in the process of actually using electronic products, people are often affected by "glare". "Glare" refers to the visual condition that causes visual discomfort and reduces the visibility of objects due to unsuitable brightness distribution or extreme brightness contrast in space or time in the field of vision. Strong glare can also cause problems such as vision loss, depression, and irritability. "Anti-glare" means that when light passes through the screen ...

AI Technical Summary

Problems solved by technology

Although these methods can all realize the anti-glare effect, there are defects: some methods are complicated in technology, high in cost, and the wear resistance of the obtained anti-glare film is not good, or can not take into account both wear resistance and flash point problems; To improve the sharpness and visual effects of display devices, the problem of flash point must also be taken seriously

[0004] The patent with the publication number CN109810555A discloses a high-hardness, anti-glare hardened layer coating solution and a hardened film, which are prepared by adding silica particles to the combination system of acrylic resin and acrylic monomer to prepare high wear-resistant anti-glare film, but the flash point of the prepared anti-glare film is poor

The patent with the publication number CN104817951A discloses an anti-glare coating and an anti-glare hardened film. By adding two kinds of inorganic particles with different particle sizes to the combination system of acrylic resin and acrylic monomer, an anti-glare coating with excellent flash point is prepared. film, but the prepared anti-glare film has poor abrasion resistance

The patent publication No. CN102762644A discloses a coating for an anti-glare film and an anti-glare film comprising the coating, the coating for an anti-glare film includes a binder resin, organic particles and inorganic particles, and the The difference in the refractive index of the binder resin and the organic particles and the difference in the refractive index of the binder resin and the inorganic particles are each 0.3 or less, and the prepared anti-glare film has excellent anti-glare properties , image clarity and contrast, but there is no essential improvement in wear resistance

[0005] For this reason, it is necessary to design a low-flash point, high wear-resistant anti-glare film, which can overcome the problem that the existing wear-resistant and flash point cannot be taken into account.
