Abstract

The invention belongs to the technical field of glass chemical etching, and particularly relates to a glass etching solution, a high alumina-silica glass etching method and high alumina-silica glass with textures on the surface. The glass etching liquid comprises the following raw materials in percentage by mass: 5-15 wt% of ammonium fluoride; 10-22 wt% of ammonium bifluoride; 8-18 wt% of potassium bifluoride, 5-15 wt% of hydrochloric acid, 15-30 wt% of nitric acid, 3-8 wt% of potassium chloride, 1.5-6 wt% of copper sulfate, 3-8 wt% of NaNO3, 3-8 wt% of NaH2PO4, 2-5 wt% of FeCl3 and 10-30 wt%of H2O. The glass etching solution can be used for etching high alumina-silica glass to form snowflake-like concave-convex textures on the surface of the high alumina-silica glass.

Description

technical field [0001] The invention belongs to the technical field of glass chemical etching, and in particular relates to a glass etching solution, a high-alumina-silicate glass etching method and a high-alumina-silicate glass with texture on the surface. Background technique [0002] With the advent of the 5G information age, in order to prevent the blocking and shielding of smartphone signals, the material selection of the back cover of the mobile phone is mainly concentrated in glass and ceramics. The field of glass back cover has been promoted and applied. If the 3D glass casing of mobile phones and other electronic devices can have snowflakes or other patterns that are popular with consumers, it will greatly enrich the decoration grade and connotation of the back cover of mobile phones and other electronic devices, and it will be easier Be favored by consumers. [0003] At present, the snowflake effect is only realized by acid etching technology on the surface of ord...
