Abstract

The invention relates to a transparent heat insulation coating material, the preparation method and the application thereof. The material is made from the raw material of lanthanum hexaboride / tin indium oxide or lanthanum hexaboride / tin antimony oxide, by the steps of pretreating by ultrasonic dispersion, and grinding to prepare nanometer slurry with heat insulation function, wherein the nanometer slurry has particle sizes mainly between 10nm and 200nm, the average particle size between 50nm and 120nm, and superior dispersion stability; mixing the nanometer slurry with film forming substance, auxiliary agent and solvent, to obtain the transparent heat insulation coating material. The coating material can obstruct more than 80% of infrared light, has a visible light transmittance above 60%, achieves excellent transparency and sunshine energy shielding effect; can be directly coated on transparent glass, polycarbonate, synthetic glass and polyester; and achieves the aims of energy conservation and heat insulation.

Description

technical field

[0001] The invention belongs to the technical fields of chemical industry and paint, and in particular relates to a transparent heat-insulating coating material and its preparation method and application. 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.

[0003] 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...
