Nano Tungsten Oxide Applied for Heat Insulation Glass Coating

Nano tungsten oxide may be used to produce a new type of heat insulation glass coating with advantages of excellent heat insulation, high transparency, good anti-UV effect, simple construction and high cost performance. And such a smart heat insulating coating may be applied for architectural glass windows or glass doors.

So, how to prepare nano tungsten oxide heat insulation glass coating? The heat-insulating anti-UV coating can be composed of mixed slurry of nano tungsten oxide and antimony tin oxide with a particle diameter of 5-10 nm, a resin and a diluent. Wherein, the weight percentage of the mixed slurry of the nano tungsten oxide and the antimony tin oxide, the resin and the diluent are 14%-18%, 1%-3% and 79%-85%, respectively. A suitable nano tungsten oxide is an alcohol solution or an aqueous solution with a solid content of 30%, and the antimony tin oxide is an aqueous solution or an alcohol solution with a solid content of 30%. And the alcohol is n-butanol or ethanol. The resin is a silicone resin, a modified silicone resin, and an acrylic resin. The diluent is selected from alcohols and water. And the alcohols are n-butanol or ethanol.
