Abstract

The invention provides a method for preparing high-tenacity high-hardness anti-dazzle glass. The method comprises the steps that firstly, raw materials needed for manufacturing the glass are prepared, then the raw materials are evenly mixed and ground to obtain a mixture, the mixture is placed in a smelting furnace, and then composite clarifying agents are added for clarifying; the mixture is cooled to room temperature, a material a is obtained, the material a is formed, then annealing treatment is carried out, and a material b is obtained; after coring treatment and crystallization treatment are carried out on the material b, a material c is obtained; the material c is preheated, preheating temperature ranges from 720 DEG C to 820 DEG C, and heat preservation is carried out for 1-2 h; then the material c is placed in frosting liquid to be soaked for 60-80 s, a polishing solution is sprayed to the material c for 3-10 min, then the material is taken out to be washed, dried and air-cooled to room temperature, and the high-tenacity high-hardness anti-dazzle glass is obtained.

Description

technical field [0001] The invention relates to a method for preparing glass, in particular to a method for preparing antiglare glass with high toughness and high hardness. Background technique [0002] Anti-glare glass is also called anti-reflective glass or non-reflective glass. Anti-glare glass reduces the reflectivity of the glass surface, so that the reflectivity is ≤2%, the light transmittance is ≥80%, and the glossiness is ≥60%. Anti-glare 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 and reduce the reflectance of light. To less than 1%, thereby reducing the interference of ambient light, improving the clarity of the picture, reducing the reflection of the screen, making the image clearer and more realistic, allowing viewers to enjoy better visual effects. [0003] The toughness and hardness of the anti-glare glass in th...
