Abstract

The invention proposes a preparation method of high-toughness and high-hardness anti-glare glass. Firstly, the raw materials required for making glass are prepared, and then the raw materials are mixed evenly, and the mixture is ground to obtain the mixture, which is placed in a melting furnace, and then a compound clarifier is added for clarification. , cooled to room temperature to obtain material a, then material a is molded, and then annealed to obtain material b, and then material b is subjected to nucleation and crystallization treatment to obtain material c, then preheated, preheated The temperature is 720-820°C, keep warm for 1-2 hours, then soak in the frosting solution for 60-80s, then spray with polishing solution for 3-10 minutes, take it out, wash, dry, and air-cool to room temperature to obtain high toughness, high hardness and anti-glare Glass.

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...
