Violet tungsten oxide for preparing near infrared shielding material is an environmentally friendly water-based coating with unique properties. It not only has good light transmission, but also has ideal selectivity for solar spectrum. The heat insulation material of violet tungsten oxide nanopowder can effectively isolate solar heat radiation with excellent resistance to aging. And it also has the properties of stain resistance, self-cleaning, anti-static, anti-glare, and anti-radiation.
The kind of heat insulation material made of violet tungsten oxide nano powder is the best material for solving the problem of heat insulation in semiconductor materials. It only needs to be painted with a thickness of several micrometers to make the indoor and outdoor temperature difference reach about 10°C, the shielding rate of infrared rays reaches 70%, the visible light transmittance reaches 80%, and the ultraviolet blocking rate reaches 99%. Even if the air conditioner is not turned on, it can achieve the effect of "warm winter and cool summer", and therefore it can be widely used in automobiles and various buildings.
