Problems solved by technology

[0006] The glass processed in these two different ways has its own advantages and disadvantages. AG glass has better anti-reflection ability, but relatively low transmittance; AR glass has high transmittance, but poor anti-reflection ability.
This shortcoming has led to the fact that the single-process anti-reflective glass cannot meet the requirements of some practical applications in the current market: high anti-glare and high light transmission
At the same time, the current AR coating process of glass is mainly produced by magnetron sputtering, which has high cost and low efficiency, which is not conducive to large-scale industrial production

Abstract

The invention discloses glass with high anti-dazzle property and high light transmittance and a preparation process thereof. The surface of the glass is coated with an etching layer with the thickness of 0.10 to 0.20 [mu]m, a SiO2 thin film with the thickness of 0.05 to 0.15 [mu]m and a TiO2 thin film with the thickness of 0.02 to 0.10 [mu]m. The preparation process of the glass comprises the following steps: (1) cleaning: cleaning the glass with water or ethyl alcohol; (2) etching: etching the surface of the cleaned glass with an etching solution; (3) polishing: polishing the etched glass surface with a mixed acidic solution with hydrofluoric acid and sulfuric acid; (4) film plating: plating the SiO2 thin film and the TiO2 thin film on the polished glass surface in sequence. The light transmittance of the glass disclosed by the invention is not less than 93 percent, and the light reflection rate is not greater than 0.5 percent. The preparation process disclosed by the invention is low in cost and easy to operate.

Description

technical field [0001] The invention relates to glass, in particular to a high anti-glare and high light transmission glass and a preparation process thereof. Background technique [0002] Various display terminals currently on the market, such as liquid crystal displays and liquid crystal televisions, are affected by external light sources, and the imaging effect and definition of the display terminals will be significantly reduced. [0003] In response to this problem, people have proposed the method of using anti-reflective glass in the 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 field of the display terminal, such as outdoor advertising machines. [0004] The anti-reflection glass currently on the market can be divided into two categories according to different anti-reflection principles: one is that it forms a granular surface on the surface of the glass panel through a...
