Etching solution with satin-like silky effect and process for manufacturing mobile phone glass rear cabinet with etching solution

Abstract

The invention discloses an etching solution giving glass a satin-like silky effect and a process for manufacturing a process for manufacturing a mobile phone glass rear cabinet with the etching solution. The etching solution is prepared from the following raw materials in percentage by mass: 8-12 percent of NH4HF2, 3-6 percent of KHF2, 5-8 percent of HF, 15-25 percent of H3PO4, 8-12 percent of C6H8O7, 1-1.5 percent of K2HPO4, 5-10 percent of K2SO4, 0.8-1.5 percent of ZnCl2, 0.2-0.8 percent of sodium alkyl benzene sulfonate, 0.2-0.5 percent of polyacrylamide, 3-8 percent of polyvinyl alcohol, 3-6 percent of glycerinum and 25-40 percent of H2O. The process comprises the following steps: performing acid etching treatment on a mobile phone rear cabinet made of a high-aluminum high-silicon glass material and forming a corrugated concavo-convex etching layer with micro-level thickness, so that a silky fine texture and smooth hand-feeling touch effect is generated on the mobile phone rear cabinet glass surface, and the mobile phone rear cabinet glass has excellent characteristics of silky smoothness, scratch resistance, fingerprint resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of etching glass, and in particular relates to an etching solution with a velvet silky effect and a manufacturing process for a mobile phone glass rear case. Background technique [0002] With the popularization and promotion of smart phones, the diversified and differentiated decoration needs 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. At present, the commonly used frosting technology is through frosting liquid Frosting etching on the glass substrate can make the glass substrate obtain a hazy appearance effect and improve the visual effect of the appearance of the mobile phone rear case; however, the current conventional etching formula and etching process produce The delicate and silky etching effect does not reach the silky tactile effect of velvet satin.
