Abstract

The invention discloses a manufacturing process of a high alumina-silica glass square flash point effect, which comprises the following steps of: (1) preparing a high alumina-silica glass square flashpoint effect etching solution, and putting the etching solution into an etching sand spraying device; (2) carrying out silk-screen covering protection on one surface, which does not need to be etched, of a mobile phone rear shell original sheet made of a high alumina-silica glass material by using anti-etching ink; (3) cleaning and air-drying one surface, which needs to be etched, of the mobile phone rear shell original sheet made of the high alumina-silica glass material, and putting the original sheet into the etching sand spraying device in a dry state to carry out sand spraying etching treatment; and (4) taking out the etched mobile phone rear shell original sheet made of the high alumina-silica glass material from the etching sand spraying device, polishing the mobile phone rear shell original sheet with a polishing solution, cleaning the mobile phone rear shell original sheet, and finally air-drying or drying the mobile phone rear shell original sheet. According to the invention, frosting etching treatment is carried out on the mobile phone rear shell made of the high alumina-silica glass material, a layer of square columnar microcrystalline particles with micron-sized thickness is formed on the surface of the glass, and the surface of the glass has a starlight flickering effect under the condition of facing light.

Description

technical field [0001] The invention belongs to the technical field of etching glass, and in particular relates to a manufacturing process of high-alumina-silicate glass square flash point effect. Background technique [0002] With the popularization and promotion of 5G smartphones, the diversified demands of mobile phone models have also emerged. The frosting decoration of the glass back shell of the mobile phone is more and more popular among people. Frosted etching can make the glass substrate have a hazy appearance and improve the appearance and visual effect of the rear case of the mobile phone. However, at present, the frosting liquid, frosted glass and its processing method for frosting and etching the glass substrate, as well as the special etching effects produced still need to be improved. Different special etching effects require different frosting liquid formulations and different etching methods. process method. Contents of the invention [0003] The purpose...
