Water-soluble solid etching reagent for anti-dazzle high-aluminum glass, and etching process for high-aluminum glass

Abstract

The invention provides a water-soluble solid etching reagent for anti-dazzle high-aluminum glass, and an etching process for the high-aluminum glass. The solid etching reagent comprises the followingraw materials by weight: 15-45 parts of ammonium bifluoride, 20-60 parts of citric acid, 6-15 parts of ammonium sulfate, 2-14 parts of potassium bifluoride or potassium sulfate, 1-10 parts of titaniumdioxide, and 5-50 parts of a thickener. The solid etching reagent disclosed by the invention can be dissolved in water, so strong acid and toxic organic solvents are not used; the high-alumina glasscan be well etched under the condition of normal temperature; and the prepared finished anti-dazzle high-alumina glass product can generate a good anti-dazzle effect.

Description

technical field [0001] The invention relates to the technical field of functional glass products, in particular to a water-soluble antiglare high-alumina glass etching solid reagent and a high-alumina glass etching process. Background technique [0002] At present, the anti-glare glass sold in domestic and foreign markets is generally achieved by coating the glass surface or corroding the glass surface by using hydrofluoric acid. The anti-glare glass prepared by coating method has better effect, but the process is complicated, and it is generally required to be carried out under vacuum conditions, the cost is high, and the film layer is easy to fall off when used outdoors, with poor weather resistance and abrasion resistance. Appearance, transmittance, etc. have an impact. The traditional glass etching technology uses hydrofluoric acid and concentrated sulfuric acid under elevated temperature conditions. The glass surface is corroded by hydrofluoric acid to form a frosted s...

Problems solved by technology

Although the production method of this invention is simple, easy to operate, and saves manpower, it still needs to add reagents such as hydrochloric acid and sulfuric acid, which belong to the anti-glare reagent formula that needs to add acid solvents. Using these strong acids will pollute the environment, and hydrochloric acid is highly volatile. , resulting in poor stability of the etchant, making it difficult to be recycled
