High-alumina glass frosting liquid and preparation method thereof

Abstract

The invention discloses a high-alumina glass frosting liquid and a preparation method thereof. The high-alumina glass frosting liquid comprises the following components in parts by weight: 30-45 partsof ammonium bifluoride, 5-15 parts of citric acid, 2-5 parts of barium sulfate, 4-10 parts of starch, 2-6 parts of bentonite, 10-20 parts of ferric trichloride, 5-15 parts of potassium fluoride, 6-13parts of potassium nitrate, 2-6 parts of hydrofluoric acid and 10-30 parts of water. The frosting liquid is low in manufacturing cost and high in production yield; and anti-dazzle glass prepared fromthe frosting liquid has the characteristics of high glossiness, low flash point, low roughness and good anti-dazzle effect.

Description

technical field [0001] The invention belongs to the technical field of glass surface processing, and in particular relates to a high-alumina glass frosting liquid and a preparation method thereof. Background technique [0002] AG (Anti-glare glass) glass is also called anti-glare glass. It has a special treatment on the surface of the glass, so that it has a lower reflectance than ordinary glass, reduces the reflection of the screen, and makes the display screen clearer and more realistic. The manufacture of AG glass is generally divided into three processes: spraying, coating and etching. Spraying AG glass is to apply a layer of chemical substances on the surface of the glass to form concave-convex particles to achieve anti-glare effect by means of evaporation coating; coated AG glass is to deposit a film on the surface of the glass, so that the surface can resist light reflection Substance; Etching AG glass is to etch the glass surface by chemical etching to form an uneve...

Problems solved by technology

In the prior art, patent publication numbers CN101215097A, CN1154951A and CN1400184A all use highly volatile components of hydrochloric acid, poor stability of etching solution, large changes in industrial production process, resulting in low production yield

In the patent application documents whose patent publication numbers are CN101654330A and CN103030301A, the Arabic resin used as the raw material, because the raw material is expensive, the cost of manufacturing the frosting liquid is relatively high

Compared with soda-lime glass, high-alumina glass has the advantages of good chemical stability and high mechanical strength, and the demand for high-alumina glass in the field of display covers is gradually increasing, because Al in high-alumina glass 2 o 3 The content is greater than 12%, and the hardness is relatively high. The frosting solution that can be used for soda-lime glass is not suitable for high-alumina glass. The etching stability is poor, and the production yield cannot be guaranteed.
