Abstract

The invention provides a preparation method of a high-strength anti-dazzling coating layer. A formula comprises a shells, methyl methacrylate, gamma-methacyloxypropyltrimethoxylsilane, an ethanol solvent, benzyl peroxide and nano titanium oxide; the preparation method of the coating layer comprises the steps that the shells are placed into a ball milling machine to be milled; the methyl methacrylate, the gamma-methacyloxypropyltrimethoxylsilane, the ethanol solvent, the benzyl peroxide and a tetraethoxysilane solution are added to a reactor to perform reaction; shell powder and a mixed solution are mixed, aerated and stirred; other components are added to an icy water bath; spraying and roasting are conducted to obtain the high-strength anti-dazzling coating layer. The high-strength anti-dazzling coating layer has the advantages of better hardness and substrate adhesion force, the service life of the coating layer is prolonged which the protecting effect on a substrate can be enhancedby the powerful wear resistance and anti-impacting performance of the coating layer, the anti-dazzling effect is strong, the permeable rate of a visible light is high, and the quality of a product isimproved.

Description

technical field [0001] The invention relates to the technical field of anti-glare coatings, in particular to a preparation method of a high-strength anti-glare coating. Background technique [0002] Glare is an undesirable lighting phenomenon. When the brightness of the light source is extremely high or the brightness difference between the background and the center of the field of view is large, glare will occur. The glare phenomenon not only affects viewing, but also has an impact on vision health. At present, the method of preparing an anti-glare coating on the surface of the substrate is often used to reduce the glare phenomenon. The adhesion between the anti-glare coating and the substrate prepared by the existing technology is reduced and the hardness is poor. After a period of use, it is prone to scratches and peeling off. In addition, it also has the defects of poor anti-glare effect and low visible light transmittance. The service life and product quality of the co...
