Nano Tungsten Trioxide Applied for French Window Thermal Insulating Glass Coating

Nano tungsten trioxide for French window thermal insulating glass coating is a new type of high-tech environmentally-friendly nano material with excellent heat insulation and high visible light transmittance. Among them, the raw material nano tungsten trioxide needs to be made into a transparent heat insulating dispersion before being used to produce the French window thermal insulating glass coating.

Wherein, the preparation process of nano WO3 dispersion is shown as follows: butyl acetate 40%, PMA 32%, dispersant 3%, dispersant 5%, and nano WO3 powder 20%. Add the formula amount of solvent, dispersant and stir evenly, and then slowly add the tungsten trioxide nano powder while stirring. After the powder is added, disperse it for 30 minutes at high speed. Turn on the nano grinder and perform circular grinding. Finally, the nano WO3 dispersion with a median particle diameter of about 75 nm and a solid content of 20% was obtained.
