Tungsten oxide may be used to prepare a new type of environmentally friendly heat insulation glass coating. Some experts weighed the mixed slurry of nano tungsten oxide and antimony tin oxide, resin and diluent by weight percentage, and then the slurry was mixed and dissolved by conventional techniques to obtain tungsten oxide heat insulation glass coating.

Such coating is composed of mixed slurry of nano tungsten oxide and antimony tin oxide with a particle diameter of 5 to 10 nm, a resin and a diluent. Among them, the nano WO3 is an alcohol solution or an aqueous solution with a solid content of 30%. And the nano antimony tin oxide is also an aqueous solution or an alcohol solution with a solid content of 30%. The alcohol is n-butanol or ethanol. While do you know how to prepare nano tungsten oxide alcohol (aqueous) solution? The processes are as follows:
Mix nano tungsten oxide powder of a particle size of 300-500 nm and a weight fraction of 5-30 parts, n-butanol or ethanol with a weight fraction of 40-70 parts, and a polymer type ion dispersant of a part by weight of 1-2 parts together with other aids agent. By dispersing for a certain period of time on a high-speed disperser and a ball mill, nano tungsten oxide alcohol (aqueous) solution with a particle diameter of 5 to 10 nm and a solid content of 30% can be obtained.
