Preparation method of ground glass cover plate with gradual change effect

Abstract

The invention discloses a preparation method of a ground glass cover plate with a gradual change effect. The preparation method comprises the following steps: S1, sand blasting: manufacturing a frosted layer on the surface of a glass substrate by utilizing a sand blasting technology and achieving a gradual change effect of the frosted layer by changing an included angle between the spraying direction of a nozzle and a surface normal of the glass substrate and changing a spraying velocity of the nozzle; S2, etching: etching the sand blasted glass substrate to reduce the surface roughness of theglass substrate. According to the preparation method disclosed by the invention, a glass substrate sand blasting effect is changed by changing an angle and a spraying velocity of the nozzle, so thata gradual change frosted effect of glass is achieved; the sand blasted glass substrate is etched to reduce the surface roughness of the glass substrate, and the gradual change effect is more attractive. The preparation method disclosed by the invention has the advantages of simpleness and high product yield; in actual use, fingerprints are not prone to appearing, appearance attractiveness of a product is higher, and competitiveness of the product on market is further improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment accessories, in particular to a method for preparing a frosted glass cover plate with a gradient effect. Background technique [0002] With the continuous improvement of people's living standards, electronic products such as mobile phones, tablet computers, cameras, and notebook computers have gradually become popular. At present, the cover plates of electronic products are mostly plastic or metal. This single style cannot satisfy people's pursuit of fashion and individuality. Plastic cover and metal cover have many disadvantages. Among them, the homogeneity of plastic cover is serious, and it is easy to fade after long-term use, which affects the appearance of use; although the metal cover is beautiful in appearance, metal has strong interference to signals and is easy to Defects such as scratches. In order to avoid the interference of metal on the signal, most metal cover products...
