Problems solved by technology

One of the current technologies is to cover the glass surface with a high-hydrophilic film at high temperature, which is costly
Another method is to spray a hydrophilic nano-layer on the surface. For example, CN201510064039.4 coats a SiO2/TiO2 nano-layer on the glass surface to form a convex-concave structure to form a hydrophobic surface; CN102219391A uses octa

Abstract

The invention discloses a liquid dhydrophilic glass film, a hydrophilic glass, and a preparation method of the liquid hydrophilic glass and the hydrophilic glass. The method comprises the following steps: mixing trimethoxymercaptopropyl silane with alkyl orthosilicate, uniformly stirring trimethoxymercaptopropyl silane and alkyl orthosilicate, adding ethanol, continuously stirring above materials for at least 2d to obtain a transparent solution, adding water to the transparent solution, continuously stirring above materials to completely hydrolyze trimethoxymercaptopropylsilane and alkyl orthosilicate to obtain the liquid hydrophilic glass film, coating the surface of glass with the liquid hydrophilic film, and drying the coated glass to obtain the hydrophilic glass. The method is carried out at room temperature, and has a simple process, and the glass film is firmly combined with glass, and has good hydrophilicity and long service life; and compared with present methods, the method disclosed in the invention has the advantages of simple technology, low cost and convenience in industrial production, and can be widely applied to the fields of glass curtain walls, window glasses and solar power stations.

Description

technical field [0001] The invention relates to a preparation method of a liquid hydrophilic glass film and the obtained liquid hydrophilic glass film, and also relates to a hydrophilic glass and a preparation method thereof, belonging to the technical field of nano-coating self-cleaning. Background technique [0002] Industrial development has led to the greenhouse effect, and pollution is becoming more and more serious. The living environment is facing many challenges. There are a large number of pollutants floating in the air. These pollutants will be adsorbed on the surfaces of building curtain walls, cars, etc., seriously affecting people's lives. Quality, increasing the self-cleaning function of materials has become one of the main tasks of material workers. At present, there are mainly two types of self-cleaning surfaces: highly hydrophilic and highly hydrophobic. Among them, highly hydrophilic film materials are widely used. For example, coating a layer of highly hyd...
