Problems solved by technology

[0004] Heat insulation films are usually obtained by spraying and coating heat insulation coatings. Heat insulation coatings often use resin as a film-forming substance, and heat insulation fillers are added to the coating. Therefore, the use of heat insulation films will be reduced to a certain extent. The light transmittance of the glass, it is difficult to achieve the unity of good heat insulation effect and high light transmittance for the prepared heat insulating glass

Abstract

The invention relates to the technical field of heat insulation materials, and provides a transparent heat insulation film for building glass and a preparation method of the film. The method includesrespectively preparing a methyl ethyl ketone dispersion of indium tin oxide and lanthanum molybdate; then mixing the methyl ethyl ketone dispersion with polyvinylidene fluoride / polyvinyl butyral composite sol to prepare a heat insulation coating material; and forming a transparent heat insulation film on the surface of glass by dipping and pulling. Compared with the traditional method, the transparent heat insulation film not only has a good heat insulation effect and is beneficial to building energy conservation and emission reduction, but also has high visible light transmittance and littleinfluence on the light transmittance of glass.

Description

technical field [0001] The invention belongs to the technical field of heat insulation materials, and provides a transparent heat insulation film used for building glass and a preparation method. Background technique [0002] Energy is an important material basis for human survival and development. In modern society, construction, industry, and transportation form three major "energy-consuming households". Among them, the total energy consumption of buildings accounts for about 30% of the total energy consumption in my country, and the resources and energy consumed in the whole process of construction account for about half of the total energy consumption in the world. The production, mining and transportation of building materials to the construction, operation and The whole process of building demolition and disposal not only consumes a lot of resources, but also produces a lot of pollution. And along with the increasingly prominent problem of energy shortage, saving energ...
