[0003] Patent CN102124048A discloses a method for preparing an anti-glare hardened film, by dissolving at least two mutually incompatible resins in at least one solvent, the particles migrate to the air-liquid interface of the coating, so that it is centrifugally Positioned on the surface of the coating to prepare an anti-glare hardened film; however, the prepared anti-glare hardened film has poor clarity and flash point
Patent CN101679825A discloses a composition for anti-glare cured film and the anti-glare cured film prepared by using the composition. By adding a certain amount of organic particles with a particle size of 1-10um to the binder resin, the coating surface Form a concave-convex height of 0.01-2μm to achieve the anti-glare effect, but the disadvantage is that the flash point is heavy and the clarity is not enough
[0004] At present, most anti-glare hardened film products have heavy flash points, poor clarity, and blurred images, which can no longer meet the requirements of high-definition display devices.

Abstract

The invention provides an anti-dazzle coating and an anti-dazzle hardening film. The anti-dazzle coating comprises the following components in parts by weight: 60-80 parts of polyurethane acrylate polymer with six degrees of functionality or above, 20-40 parts of acrylate monomer with six degrees of functionality or above, 10-15 parts of anti-dazzle particles with particle size of less than or equal to 500nm, 5-10 parts of anti-dazzle particles with particle size of 1-3mu m, 4-8 parts of a photoinitiator, 0.1-1 part of an organosilicone levelling agent, 0.5-1 part of an acrylic acid levelling agent and 40-80 parts of an organic solvent. The anti-dazzle coating provided by the invention is used for preparing an anti-dazzle hard coating film; two types of anti-dazzle particles different in particle size are used together so that the prepared anti-dazzle hard coating film has excellent properties of low flash point and high definition; in addition, the anti-dazzle hard coating film further has excellent levelling property so that the flash point of the anti-dazzle hardening film can be lowered further.

Description

technical field [0001] The invention relates to the technical field of anti-glare hardened films, in particular to an anti-glare coating and an anti-glare hardened film. Background technique [0002] When mobile phones, laptops, PADs and other displays are exposed to external light such as natural light, the glare pollution caused by the reflected light on the surface often makes people's eyes tired and affects the clarity of the picture. Therefore, there are more and more anti-glare hardened film products on the market to reduce the interference of reflected light on people's sight. [0003] Patent CN102124048A discloses a method for preparing an anti-glare hardened film, by dissolving at least two mutually incompatible resins in at least one solvent, the particles migrate to the air-liquid interface of the coating, so that it is centrifugally Positioned on the surface of the coating to prepare an anti-glare hardened film; but the prepared anti-glare hardened film has poor...
