The obtained heat insulating materials have excellent ultraviolet shielding property, and the ultraviolet shielding rate is equal or greater than 97%. Also, it has good infrared shielding performance, and the infrared blocking rate is equal or greater than 95%, in which the infrared wavelength range is in the range of 780-1800nm. In addition, it has good daylighting, and the visible light transmittance is equal or greater than 85%, wherein the visible light wavelength is in the range of 380-780nm.

The raw material of tungsten trioxide nanopowder used is also called tungsten trioxide nanoparticles, generally referred to as ultrafine particles of particle size between 1 and 100nm. Its scale is larger than the atomic cluster and smaller than common particle. Calculated according to its grain size, assuming that each atom is 1 angstrom in size, it contains between 1000 and 100 million atoms. It is smaller than the average biological cell and is comparable in size to the virus. The shape of the nanoparticles is spherical, plate-shaped, rod-shaped, angular, sponge-like, and the like.
