Problems solved by technology

[0003] Anti-glare glass, referred to as AG glass, is a kind of glass with special treatment on the surface of the glass. The principle is to process high-quality glass on one or both sides to make it have a lower reflectance than ordinary glass Reduce the interference of ambient light, improve the clarity of the picture, reduce the reflection of the screen, make the image clearer and more realistic, and let the viewer enjoy better visual effects. It is suitable for all kinds of monitors and protective screens. At present, the following types are more common Anti-glare glass can be prepared by advanced technology: 1. Mechanical grinding (frosting, sandblasting) directly on the glass surface or etching of the glass surface with an acidic solution mainly based on hydrofluoric acid to further form a rough surface, but this One type of method has the risk of corrosive drug operation and subsequent wastewater pollution, which is likely to cause environmental and ecological damage; 2. The surface wet coating method, the main process is to spray the solution containing silicate or Coating methods such as roll coating, the liquid medicine is evenly covered on the glass surface to form a nano-inorganic oxide film with uneven surface roughness, and subsequent heating (> 300 degrees) curing molding operation, this method has low light transmittance (<91%), not wear-resistant and low yield rate and other issues

Abstract

The invention discloses nano anti-dazzle glass for a display screen. The nano anti-dazzle glass comprises a glass substrate and an anti-dazzle coating layer, the nano anti-dazzle glass for the display screen is prepared by the following steps: 1, preparing an anti-dazzle coating material liquid; and 2, coating one side of the glass substrate with an anti-dazzle coating material liquid, compressing the anti-dazzle coating layer by using a clamp, and curing at the temperature of 60 DEG C for 5-10 min to obtain the nano anti-dazzle glass for the display screen. According to the invention, the common glass substrate is coated with the anti-dazzle coating layer, and the coating layer is extruded by using bulges on the clamp, an uneven rough surface is formed, the coating layer is endowed with tight and fine roughness by combining the characteristic of small particle size of nano-microspheres, light is changed from mirror reflection to diffuse reflection, interference on eyes is weakened, 4,4'-diaminodiphenyl disulfide has a rigid group benzene ring and a reversible self-repairing disulfide bond, so that the scratch resistance and the wear resistance of the anti-dazzle coating layer are improved.

Description

technical field [0001] The invention belongs to the technical field of anti-glare glass preparation, and in particular relates to a nano anti-glare glass for a display screen. 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 affects vision health. [0003] Anti-glare glass, referred to as AG glass, is a kind of glass with special treatment on the glass surface. The principle is to process high-quality glass on one or both sides to make it have a lower reflectance than ordinary glass, so that Reduce the interference of ambient light, improve the clarity of the picture, reduce the reflection of the screen, make the image clearer and more realistic, and let the viewer enjoy better visual effects. It is suitable for all ...
