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...
