Problems solved by technology

This method results in a very low solid content of the coating. Since the optically transparent coating can only be applied once, two coats of coating have a great impact on the optical properties. Therefore, the wet film needs to be very thick to achieve the effect.
Provided in CN1903958A is the nano-slurry method of material prep...

Abstract

The invention provides a transparent thermal insulation anti-ultraviolet coating and a preparation method thereof, belongs to the technical field chemical industry, materials and environmental protection and relates to the transparent thermal insulation anti-ultraviolet coating which can reduce the transmission of solar energy and ultraviolet and the preparation method thereof. The coating comprises nano-slurry with the thermal insulation anti-ultraviolet function and a film-forming substance, and is combined with the synergistic effects of a wetting dispersant and a hyper-dispersant for preparing the nano-slurry with high solid content and stable dispersion. The preparation process of the coating is simple and can greatly improve the solid content of the coating, ensure the optical effect of a paint film after coating, simultaneously organically combined powder with different functions and obtain the thermal insulation anti-ultraviolet functional coating with satisfactory effects. The coating has the characteristics of low transmission of ultraviolet and near infrared light of solar rays, high transmission of visible light and the like, and can be coated on glass, polycarbonate or organic glass and other transparent materials, and achieve the purposes of energy conservation and protection.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, material and environmental protection. Background technique [0002] In order to reduce solar radiation and achieve the purpose of saving energy, people use various methods to change the light transmission performance of glass. Automobile glass film can block sunlight radiation, reduce the temperature of the surfaces and air in the car, improve the riding environment of the passengers, and reduce the fuel consumption of the car. Similarly, some building energy-saving glass is coated with metal film (aluminum, silver, etc.) ) also achieves the purpose of blocking sunlight radiation and reducing air-conditioning energy consumption. In recent years, it has been found that some metal oxides have good optical barrier properties, such as antimony tin oxide (ATO) has good barrier properties to near-infrared wavelengths of 1400-2500nm, and indium tin oxide (ITO) has good barrier properties to ...
