preparation example Construction

[0031] A preparation method of anti-glare glass, comprising the following steps:

[0032] Step S110, removing dirt on the surface of the aluminosilicate glass.

[0033] The aluminosilicate glass contains silicon dioxide, aluminum oxide and an alkali metal oxide, and the alkali metal oxide is at least one selected from sodium oxide and potassium oxide.

[0034] Further, the aluminosilicate glass includes the following components in terms of molar percentage:

[0035] 60%~75% silicon dioxide, 5%~10% aluminum oxide, 5%~8% sodium oxide, 0%~3% potassium oxide, 1%~5% calcium oxide, 1%~ 5% magnesium oxide, 2%-5% boron trioxide and 0%-4% zirconium dioxide.

[0036] Silicon dioxide (SiO 2 ) is a necessary component to form aluminosilicate glass, and can improve the strength and chemical stability of aluminosilicate glass, but when its content is too high, aluminosilicate glass is difficult to melt, so its content is selected as 60 %~75%.

[0037] Aluminum oxide (Al 2 o 3 ) can i...

Embodiment 1～5

[0097] The preparation method of the antiglare glass of embodiment 1~5 is as follows:

[0098] To provide aluminosilicate glass, first use a disc brush with detergent to clean the aluminosilicate glass to remove the dirt on the surface of the aluminosilicate glass, and then use a disc brush with cerium oxide polishing powder to polish, the polished aluminosilicate The surface flatness of the glass is at least 0.01mm. After polishing, use a roller brush with deionized water to clean the aluminosilicate glass and dry it; preheat the aluminosilicate glass; then use a spray gun to spray the crystallization treatment agent on the aluminum The surface of the silicate glass is ion-exchanged to obtain anti-glare glass, the crystallization treatment agent on the glass surface is removed and the surface of the anti-glare glass is cleaned.

[0099] The spray gun used is the spray gun described in step S150 in the preparation method of the anti-glare glass.

[0100]Among them, the compos...

Abstract

A preparing method of anti-dazzle glass is disclosed. The preparing method includes steps of: preheating aluminosilicate glass, spraying a crystallization treating agent onto the surfaces of the aluminosilicate glass with a spraying gun, and subjecting the crystallization treating agent and the aluminosilicate glass to ion exchange for 3-15 min so as to form a crystallization layer with non-uniform thickness on each surface of the aluminosilicate glass, wherein the crystallization treating agent comprises fused salts, the fused salts comprise 70-100% by mass of a lithium salt and 0-30% by mass of a sodium salt, the lithium salt is a mixture of lithium chloride and at least one of lithium nitrate and lithium sulfate or is lithium chloride, and the sodium salt is selected from at least one of sodium chloride, sodium nitrate and sodium sulfate. The preparing method has characteristics of few environment pollution and simple process.

Description

technical field [0001] The invention relates to a preparation method of antiglare glass. Background technique [0002] In recent years, a large number of high-rise buildings have been built all over the world, and their exteriors are increasingly decorated with glass curtain walls. The problem of light pollution caused by them has become increasingly prominent, and people have paid more and more attention to their serious consequences. At the same time, the glass of LCD screens, LCD touch screens and showcase windows often reflect light so that people can't see the content clearly. Since light pollution is difficult to eliminate or reduce through decomposition, conversion and dilution like other pollution, prevention should be the main priority. In this context, people started the development of anti-glare glass. [0003] At present, the preparation technology of anti-glare glass is mainly divided into mechanical method and chemical method. The methods of mechanical proce...
