Abstract

The invention discloses an aqueous glass frosting powder chemical composition containing a mixed material of an inorganic fluorine compound capable of generating fluorine ions in water, a solid acid compound capable of dissolving in water, an assistant and a filling agent, wherein the mixed material is doped with at least one surfactant; the adding amount of the inorganic fluorine compound is 20 to 90 percent of the total weight percentage of the frosting powder; the adding amount of the solid acid compound is 10 to 60 percent of the total weight percentage of the frosting powder; the adding amount of the filling agent is 1 to 30 percent of the total weight percentage of the frosting powder; the adding amount of the surfactant is 0.1 to 10 percent of the total weight percentage of the frosting powder; and during use, the water is 20 to 100 percent of the total weight percentage of the frosting powder to prepare frosting powder liquid. The technical scheme can avoid acid pollution of the production environment and natural environment because of the inevitable strong acid medium such as sulphuric acid and hydrochloric acid when frosting a glass product by using the prior glass frosting liquid.

Description

technical field [0001] The invention relates to the chemical composition of glass frosting powder, in particular to a water-based chemical composition of glass frosting powder and a preparation method thereof, belonging to the glass frosting production technology category. Background of the invention [0002] Glass frosting can make glass have a hazy and beautiful appearance, and has been widely used in daily life and industrial production. For a long time, the glass frosting processing industry has been using the method of sandblasting and chemical reaction on the glass surface to make glass frosting products. Common chemical glass etching is performed by fluoride ions in solution and silicon atoms in the glass surface structure. Chinese patents ZL96122275.1, ZL00110528.0, and ZL01126383.0 all describe technical methods involving frosting treatment of glass products. The above-mentioned technologies all use hydrofluoric acid or various fluorides as the main means of etchi...
