Embodiment 1

[0040] The present embodiment provides a kind of preparation method of glass pretreatment liquid, and its step comprises:

[0041] S100, taking sulfuric acid according to a certain volume ratio and adding an appropriate amount of deionized water to mix evenly to obtain a mixed solution A; wherein the mass fraction of sulfuric acid is 98%;

[0042] S200. Weigh ammonium bifluoride and sodium fluoride according to a certain weight ratio and add them to the mixed solution A, and mix evenly to obtain the mixed solution B;

[0043] S300. Measure nitric acid according to a certain volume ratio and add it to the mixed solution B and mix evenly to obtain the mixed solution C;

[0044] S400. Measure benzalkonium bromide according to a certain volume ratio and add it to the mixed solution C and mix evenly to obtain the glass pretreatment solution.

[0045] The above steps are carried out at a temperature above 45°C, and the pretreatment liquid prepared by the above steps includes 5% nitri...

Embodiment 2

[0048] The preparation steps of this embodiment are basically the same as those of Example 1, except that the glass pretreatment solution prepared in this embodiment includes the following components: 8% nitric acid, 15% sulfuric acid, 9% ammonium bifluoride, 3.5% sodium fluoride, 2% benzalkonium bromide and appropriate amount of deionized water; wherein, the temperature of the solution is controlled above 45° C. to obtain a finished product. By using nitric acid, sulfuric acid, ammonium bifluoride, sodium fluoride, benzalkonium bromide and deionized water as raw materials to prepare glass pretreatment liquid, it is not only cheap, but also has a good cleaning effect, and does not need to be cleaned many times, reducing work strength. At the same time, the glass pretreatment solution prepared in this embodiment is used to treat the glass to be etched, and the treatment effect is basically the same as that in embodiment 1.

Embodiment 3

[0050] The preparation steps of this embodiment are basically the same as those of Example 1, except that the glass pretreatment solution prepared in this embodiment includes the following components: 10% nitric acid, 15% sulfuric acid, 8% ammonium bifluoride, 3.5% sodium fluoride, 2% benzalkonium bromide, and an appropriate amount of deionized water; wherein, the temperature of the solution is controlled above 45°C to obtain a finished product; by using nitric acid, sulfuric acid, ammonium bifluoride, sodium fluoride, Benzalkonium bromide and deionized water are used as raw materials to prepare the glass pretreatment solution, which is not only cheap, but also has a good cleaning effect, without the need for multiple cleanings, which reduces the work intensity. At the same time, the glass pretreatment solution prepared in this embodiment is used to treat the glass to be etched, and the treatment effect is basically the same as that in embodiment 1.

Abstract

The invention belongs to the field of glass treatment, and particularly relates to glass pretreatment liquid, and a preparation method and application thereof. According to the glass pretreatment liquid, water serves as a solvent, and solutes comprise villiaumite and benzalkonium bromide with the mass ratio not lower than 1%; meanwhile, in the preparation process of the pretreatment liquid, the preparation temperature needs to be controlled to be 45 DEG C or above; and when the glass pretreatment liquid is used, an ideal treatment effect can be achieved only by soaking glass in the pretreatment liquid for about 1-10 min. The glass pretreatment liquid has the effect of powerfully removing an oxide layer on the surface of glass, can remove mildew, dark scratches and the like on the surface of the glass, has the characteristics of being high in effect, low in cost, environmentally friendly and the like due to the fact that the villiaumite accounts for a low mass ratio, has comprehensive functions and can remove tin spots, dirt, dark scratches, fingerprints, mildew spots and the like, and therefore the cleaning cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of glass treatment, and more specifically relates to a glass pretreatment liquid, its preparation method and its application. Background technique [0002] There may be mildew, anti-mildew powder adhesion, tin point adhesion, dark scratches and other hard-to-find and difficult-to-handle substances on the glass surface. These substances will cause permanent defects in the glass during the etching process, thus affecting the product. yield. The glass pretreatment liquid itself has the ability to treat the oxides on the glass surface. At present, the glass pretreatment liquid used in the market is mainly a mixed solution of hydrofluoric acid and water. It has no effect on tin spots, dark scratches, and anti-mildew powder. Direct removal can only remove oil stains and dirt that may exist on the glass surface. [0003] For example, in Patent Document 1, a method for surface treatment of liquid crystal display panel glass...
