Abstract

The invention discloses high anti-dazzle glass and a preparing technology. An etchant layer with the depth of 0.10 micron to 0.20 micron is arranged on the surface of glass, and comprises compact, regular and honeycomb hexagon etched patterns. The preparing technology includes the following steps of 1, cleaning , wherein the surface of the glass is cleaned with water or deionized water; 2, etching, wherein etching liquid is sprayed to the surface of the glass with the spraying method, and comprises, by weight, 35-45 parts of ammonium bifluoride, 4-15 parts of ammonium sulfate, 5-10 parts of ammonium nitrate, 5-10 parts of barium sulfate, 4-8 parts of potassium sulfate, 60-100 parts of hydrochloric acid and 20-40 parts of water; 4, polishing, wherein the etched surface of the glass is polished through mixed acid liquid of hydrofluoric acid and sulfuric acid. The reflective rate of the high anti-dazzle glass prepared with the technology is smaller than or equal to 3%, the light transmittance is larger than or equal to 90%, the roughness degree is as low as 0.15 micron or below.

Description

technical field [0001] The invention relates to the field of glass, in particular to a high anti-glare glass and a preparation process thereof. Background technique [0002] Various display terminals on the current market, such as LCD monitors and LCD TVs, are affected by external light sources, especially in strong light environments, the glass on the screen will reflect strong light, and the imaging effect and clarity of the display terminal will be affected. It will be significantly reduced, causing the user to be unable to look at the screen normally and perform related operations; it will cause great inconvenience to the user; at the same time, the user experience will be greatly reduced. In response to this problem, people have proposed the method of using anti-reflective glass in front of the display terminal to reduce the impact of external light sources on the display terminal, and at the same time expand the application fields of the display terminal, such as indoo...
