Process for mfg. self-cleaning antifog glass

Abstract

A self-cleaning antifog glass is prepared through preparing sol from butyl titanate, absolute alcohol and triethanolamine, pretreating glass, coating the sol on the glass, drying the film, washing with the alcohol solution of water and butanol, and calcining.

Description

technical field [0001] The invention relates to a method for manufacturing self-cleaning anti-fog glass, especially refers to the use of nano-TiO 2 The method of manufacturing self-cleaning glass by sol method as main material belongs to the method of preparing glass surface film. Background technique [0002] With the rapid development of the economy, the improvement of people's living standards and the increasing level of urbanization, the rapid accumulation of automobiles, urban public buildings, especially urban high-end curtain wall buildings, there will be a large number of these facilities The use of decorative glass for lighting. Although the glass in daily use can bring us a dazzling living environment, it also brings us troubles in use: that is, how to solve the problems of surface dirt and atomization encountered in use. [0003] Since the discovery of TiO by Japanese scientists in the 1970s 2 Since it has photocatalytic properties, TiO 2 The obvious removal e...

Problems solved by technology

[0005] However, most of the TiO 2 Self-cleaning anti-fog glass, due to the remaining unhydrolyzed titanate residues in the titanium sol, iridescent spots often appear on the coated glass in use, which significantly reduces the transparency of the glass, resulting in a decline in the product qualification rate. reduce
