The heat insulation coating of tungsten trioxide nano particles has excellent compatibility with the glass substrate, and has good spreading and leveling properties. Also, such coating has strong and long-lasting adhesion so that it is not easy to fall off. Such thin, highly transparent thermal insulation coating shields near-infrared rays and UV light. Moreover, the chemical properties of the raw material tungsten trioxide nanoparticles are stable, and the physical changes caused by the external environment such as heat and humidity are small so that the infrared radiation and the ultraviolet radiation can be prevented effectively for a long time. More specifically, the infrared shielding rate is 95%, and the ultraviolet shielding rate is up to 99%.
