Abstract

The invention belongs to the technical field of energy-saving building materials, and relates to special glass, in particular to a double-layer infrared film glass with the functions of anti-reflection, self-cleaning and radiation cooling. The glass is used as the base and the core-shell structure of silicon dioxide is coated with titanium dioxide. As the upper film, a single-layer zinc oxide coating is used as the lower film, and the two films are combined by spin coating deposition method, wherein the upper film is a single-layer titanium dioxide-coated silicon dioxide core-shell structure with a thickness of 500-600 nm; The lower film is a single-layer zinc oxide coating with a thickness of 1000-3000 nm. The invention also discloses a preparation method of the glass. The double-layer infrared film glass with anti-reflection, self-cleaning and radiation cooling functions disclosed by the present invention has high transmittance in the visible light band and high reflectivity in the infrared band, and has anti-reflection, self-cleaning and radiation cooling functions. Cooling and other properties, the preparation method is simple and efficient, green and environmentally friendly, can be applied to infrared energy-saving windows, and is expected to be industrialized.

Description

technical field [0001] The invention belongs to the technical field of energy-saving building materials and relates to special glass, in particular to a double-layer infrared film glass with anti-reflection, self-cleaning and radiation cooling functions and a preparation method thereof. Background technique [0002] Due to the rapid growth of energy demand and the deterioration of environmental conditions, the development of energy-saving materials and renewable resources is attracting widespread attention. Windows, as building components, can effectively regulate the solar radiation passing through the building, and are regarded as effective components in regulating solar energy among energy-efficient building materials. Energy-efficient windows can control the amount of heat delivered by sunlight by changing the home's solar factor and radiative transmission across the solar spectrum. However, some energy-saving windows sacrifice the light transmittance in the visible lig...
