Tungsten trioxide can be made into tungsten trioxide nano slurry first, and then used together with other components to produce bathroom thermal insulating film. Some experts have prepared a high-performance PVB thermal insulation film, whose composition and mass percentage are: tungsten trioxide nano slurry of 0.1?0.5%, wherein tungsten trioxide particle diameter in the slurry is less than 20nm; PVB resin powder of 50?50.80%; plasticizer of 18?45%; antioxidant of 0.1?1%; UV absorber of 0.05?1%.
