Embodiment 1

[0037] A high-strength tempered glass cover plate chemical polishing agent, which includes the following raw materials in parts by weight:

[0038]

[0039] The anionic surfactant is sodium dodecylsulfonate; the nonionic surfactant is AEO-9.

[0040] The preparation method of the above-mentioned chemical polishing reagent is as follows: according to the parts by weight of each raw material, first mix each raw material, then raise the temperature of the mixed solution to 40°C, and finally stir at a speed of 200r / min for 17.5min to obtain the chemical polishing reagent. Polishing reagent.

[0041] The method for chemically polishing the high-strength tempered glass cover includes the following preparation steps:

[0042] A. Cutting, cut a large piece of glass into small pieces of glass; then carry out CNC edge grinding and drilling on the glass, laminate and polish the CNC processed glass, so that the rough surface produced by CNC on the edge of the glass is polished, The s...

Embodiment 2

[0048] A high-strength tempered glass cover plate chemical polishing reagent, the difference between embodiment 2 and embodiment 1 is that the anionic surfactant is sodium dodecylsulfonate, sodium dodecylbenzenesulfonate by weight ratio of 1:1 composition mixture.

[0049] The nonionic surfactant is a mixture of AEO-9 and glycerol polyoxyethylene polyoxypropylene ether in a weight ratio of 1:1.

[0050] The preparation method of the chemical polishing reagent for the high-strength tempered glass cover plate and the chemical polishing method for the high-strength tempered glass cover plate in Example 2 are the same as those in Example 1, and will not be repeated here.

Embodiment 3

[0052] A high-strength tempered glass cover plate chemical polishing reagent, the difference between embodiment 3 and embodiment 1 is that the anionic surfactant is sodium dodecylsulfonate, sodium dodecylbenzenesulfonate, isooctyl alcohol A mixture of ether phosphates in a weight ratio of 1:1:1.

[0053] The nonionic surfactant is a mixture of AEO-9, glycerol polyoxyethylene polyoxypropylene ether, and alkylphenol polyoxyethylene ether in a weight ratio of 1:1:1.

Abstract

The invention relates to the technical field of chemical polishing, in particular to a high-strength tempered glass cover plate chemical polishing reagent and a polishing method. The high-strength tempered glass cover plate chemical polishing reagent is prepared from the following raw materials in parts by weight: 10-30 parts of sodium hydroxide, 5-20 parts of an anionic surfactant, 10-20 parts ofa nonionic surfactant, 1-5 parts of sodium citrate and 25-50 parts of deionized water. Glass is polished by the chemical reagent, the microscopic smoothness of the glass surface and the strength of the glass are improved advantageously, and pollution to the environment is low.

Description

technical field [0001] The invention relates to the technical field of chemical polishing, in particular to a chemical polishing reagent and a polishing method for a high-strength tempered glass cover plate. Background technique [0002] With the rapid development of the smart touch industry, consumers' mobile phones accidentally drop to the ground and the screen is broken. Faced with such problems, the strength of the glass cover must be strengthened. In order to improve the strength, not only the strength of chemical tempering must be improved, but also the glass must be treated before and after chemical tempering. At present, the glass cover plates on the market are mainly mechanically polished to reduce the defects of the glass and improve the strength of the glass after tempering. However, the output of mechanical polishing is low, and a large amount of equipment needs to be invested. The efficiency is low, and the reduction of defects on the glass surface is limited, r...
