Glassware etching liquid and etching method thereof

Abstract

The invention discloses a glassware etching liquid and an etching method thereof. The etching liquid comprises, by weight, 10-20 parts of ammonium sulfate, 10-20 parts of ammonium bifluoride, 6-12 parts of potassium sulfate, 5-15 parts of trifluoromethanesulfonic acid, 3-12 parts of sodium ethylenediamine tetramethylenephosphonate, 2-10 parts of 1,2-ethanedisulfonic acid, 1-8 parts of ceric ammonium nitrate, 6-12 parts of oxalic acid, 4-10 parts of sodium benzoate, 2-6 parts of triethanolamine, 2-8 parts of methylbenzotriazole, 1-5 parts of an oxidant, 1-5 parts of a surfactant, 1-3 parts of a complexing agent and 30-50 parts of water. The etching method comprises the following steps: uniformly mixing and ageing the above raw materials to form the etching liquid, cleaning and drying glassware with an organic solvent, shielding one side, not needing etching, of the glassware, immersing the glassware in the etching liquid, taking out and cleaning the glassware, and drying the cleaned glassware. The etching liquid has the advantages of simplicity in preparation, excellent stability, recycling and low cost, and the etching method can make the finally obtained glassware have a good anti-dazzle effect and have the advantages of good reliability and good durability.

Description

technical field [0001] The invention belongs to the field of glass product processing, and in particular relates to a glass product etching solution and an etching method thereof. Background technique [0002] At present, the anti-glare glass sold in the domestic and foreign markets is generally realized by two methods, one is to coat the glass surface, and the other is to etch the glass surface with acid. The anti-glare effect of coated anti-glare glass is better, but the production cost is high, and the coating film is easy to fall off, and the surface is easy to leave scratches, etc., which affects the transparency. Generally, the acid-etched anti-glare glass first frosts the glass surface, and then polishes the frosted surface of the glass. Although it can overcome the defects that the coating film is easy to fall off and the surface is easy to be scratched, the production process is relatively complicated and the production cycle is long. , The yield is low.

The anti-glare effect of coated anti-glare glass is better, but the production cost is high, and the coating is easy to fall off, and the surface is easy to leave scratches, etc., which affects the transparency

Generally, the acid-etched anti-glare glass first frosts the glass surface, and then polishes the frosted surface of the glass. Although it can overcome the defects that the coating film is easy to fall off and the surface is easy to be scratched, the production process is relatively complicated and the production cycle is long. , low yield

[0003] In order to improve the production process of acid-etched anti-glare glass, the Chinese patent with the patent publication number CN101654330 describes processing anti-glare with glass anti-glare etching solution consisting of hydrofluoric acid, hydrochloric acid, ammonium bifluoride, gum arabic powder and polyethylene glycol The production process of glass, although this production process is simple, easy to operate, but gum arabic powder is expensive, and cost is higher, and because hydrochloric acid volatility is strong, etching solution stability is poor, is difficult for recycling; Patent publication number is CN101215097 China The patent describes the process of preparing anti-glare glass with an anti-glare glass etching solution consisting of hydrochloric acid or sulfuric acid, ammonium bifluoride, ammonium sulfate, calcium fluoride and potassium sulfate. Also due to the strong volatility of hydrochloric acid, the etching solution has poor stability and is not easy to be recycled use
