Violet Tungsten Oxide Applied for Nano Transparent Thermal Insulation Coating

Violet tungsten oxide may be applied for producing a new type of environmentally-friendly nano transparent thermal insulation coating. Specifically, firstly, the violet tungsten oxide heat-insulating nano particles are prepared into aqueous functional nano slurry. And then the thermal insulating slurry is combined with an aqueous resin to prepare thermal insulating coating.

More specifically, the nano functional slurry - aqueous thermal insulating slurry is mixed with violet tungsten oxide nano powder and deionized water, and then added with a wetting and dispersing agent, a coupling agent and the like, and dispersed in a high speed mixer or a nano ball mill. The dispersion effect of the dispersion machine on the nano slurry is: ball milling > shear dispersion > ultrasonic dispersion. Finally, under the stirring condition of the high-speed shearing disperser, the aqueous resin, deionized water and various additives are gradually added to the nano functional slurry, and after fully stirring and dispersing uniformly, the aqueous tungsten oxide transparent heat-insulating glass coating can be obtained.
