Preparation method of coated toughened glass

Abstract

The invention relates to the technical field of glass deep-processing in photovoltaic industry and discloses a preparation method of coated toughened glass. The preparation method includes providing aglass substrate and coating one side of the glass substrate with a titanium dioxide film layer; the preparation method is characterized by further coating the titanium dioxide film layer with an anti-reflective film layer and a diamond film layer sequentially; the anti-reflective film layer is prepared from a coating solution comprising isopropyl alcohol, silica solution, aluminium oxide, adhesion promoter, coupling agent of zirconium and organosilicon leveling agent. The light transmission rate of the coated toughened glass is increased by 3.5%; the coating solution refers to aqueous coatingsolution, is free of odor during use, and accordingly, physical health of users can be protected effectively; as a nano-scale silicon dioxide is taken as a basic system to prepare the inorganic hybrid film layer having porous structure, and nano-scale silicon dioxide has good binding performance with photovoltaic glass, the prepared coated toughened glass has high light-transmission rate and goodacid and alkali resistance, salt fog corrosion resistance and constant-temperature resistance performance.

Description

technical field [0001] The invention relates to the technical field of glass deep processing in the photovoltaic industry, in particular to a preparation method of coated tempered glass. Background technique [0002] Solar energy is a kind of renewable resources. With the drying up of non-renewable resources, its application has attracted more and more attention. In the process of developing and utilizing solar energy technology, solar photovoltaic power generation is the most researched and most widely used , A technology with the highest technical maturity, solar photovoltaic cell technology, as one of the most direct means of utilizing sunlight, has been widely promoted around the world, because crystalline silicon solar panels cannot be exposed to the external environment for a long time Among them, photovoltaic glass is currently one of the best packaging materials for protecting crystalline silicon cells and having high light transmittance. Among the factors that deter...
