Problems solved by technology

[0003] However, the use of this acid washing method can only wash away the surface scum, and the surface defects caused by mildew have not been fundamentally treated, and the depth of such surface defects is mostly located in the nanometer scale that matches the wavelength of visible light, which is easy to be compared with Rainbows or stripes appear due to light interference, which has a great impact on the later deep processing of glass, and cannot meet certain glass surface flatness and smoothness requirements

Abstract

The invention discloses a novel glass after-mildew restoration agent. The novel glass after-mildew restoration agent comprises the following components in percentage by weight: 1 to 20 percent of active silicate ester polymer, and 80 to 99 percent of gradient volatilization combined solvent. Scum on the surface of glass is removed by the conventional acid washing method, and a faintly acid environment of a surface defect microenvironment is caused; and after the after-mildew restoration agent is applied, the active silicate ester polymer in a formula is catalyzed by the faintly acid environment of the surface defect microenvironment, and then a nano thin layer is formed by hydrolysis, condensation reaction, and self-assembly molecular crosslinking and covalence to ensure that the surface defects of the glass are restored. The glass after-mildew restoration agent has high mobility, is convenient to use, and contributes to deep processing of glass, and the formed film is uniform and high in cleanliness.

Description

technical field [0001] The invention belongs to the field of silicate and fine chemical industry, and in particular relates to a novel repairing agent for glass mildew. Background technique [0002] In the flat glass manufacturing industry, in order to avoid the huge loss caused by the erosion and roughening of the glass surface, acid solution washing is mainly used at present. Usable acids include sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, hydrofluoric acid, fluorosilicic acid, citric acid, oxalic acid, tartaric acid and the like. Acid pool Soak the single piece of glass for 5-30 minutes or wipe it, wash it with clean water, and the mildew will be removed after it dries. [0003] However, the use of this acid washing method can only wash away the surface scum, and the surface defects caused by mildew have not been fundamentally treated, and the depth of such surface defects is mostly located in the nanometer scale that matches the wavelength of visible...
