A kind of nano-ultraviolet-proof heat-insulating coating glass and its production method

Abstract

The invention relates to a nano anti-ultraviolet heat insulation coated glass which comprises a glass plate and a layer of tin antimony oxide film on the surface of the glass plate, wherein the thickness of the tin antimony oxide film is in the range of 7-10Mu m, a plurality of tin antimony oxide particles are distributed in the tin antimony oxide film, and the diameter of any one of the tin antimony oxide particles is in the range of 1-100 nm. The production method for the nano anti-ultraviolet heat insulation coated glass comprises the following steps: cleaning the glass plate by a glass washing machine, drying the clean glass plate, filtering and heating a water body containing tin antimony oxide particles by a liquid cycle filtering and heating device, making the water body form a liquid curtain by a surface spraying device and coating the glass plate with the liquid curtain, carrying out infrared radiation on the glass plate by a temperature control infrared radiation box, and cooling the glass plate. The nano anti-ultraviolet heat insulation coated glass is easy to produce and can achieve the heat insulation effect, does not influence indoor lighting and does not pollute environment.

Description

Technical field: [0001] The invention relates to the technical field of separation and mixing, in particular to the technology of coating film processing on glass, in particular to a nano-ultraviolet-resistant heat-insulating coated glass and a production method thereof. Background technique: [0002] In the prior art, heat-insulating glass such as coated glass, Low-E online glass and Low-E offline glass are widely used in energy-saving and heat-insulation measures for buildings and vehicles. Insulating glass includes glass, dielectric layer, protective layer and silver layer, among which the silver layer can reflect the infrared rays in sunlight and play the main role of heat insulation. However, the silver layer will cause light pollution, reduce the transmission rate of visible light, and affect lighting, and the material is expensive and easily oxidized and corroded in the air, with a short lifespan. Although a layer of titanium oxide can be sputtered on the surface to ...
