Nano transparent thermal insulation coating of yellow tungsten oxide powder has a good shielding effect on ultraviolet rays and near-infrared rays. Especially in the near-infrared region, the IR shielding performance of tungsten trioxide is better than ATO and ITO.

Certainly, first of all, the yellow tungsten oxide nano powder should be made into a building glass heat-insulating medium with high transparency and high heat insulation - water-based tungsten oxide nano slurry, that is, water-based tungsten oxide heat insulating nano dispersion. And then the tungsten trioxide heat insulating dispersion is used in various resins, such as an acrylic resin, a polyurethane resin, a silicone resin or a UV resin to obtain a heat insulating coating to achieve dings such as high heat insulation, as heat preservation, and ultraviolet protection. Specifically, the obtained thermal insulating coating has a visible light transmittance of more than 70%. The near infrared ray shielding rate is greater than 90%. And the UV shielding rate is greater than 99%.
