Tungsten acid may be applied for the preparation of nano-ceramic color master so that the color master may has the advantages of high transparency, high heat insulation and low haze value. The infrared ray blocking rate of this type of nano-ceramic color master is 60~99%. The visible light transmittance is 50~80% and the haze value is less than 1. The nano-ceramic color master is widely applied in transparent plastic sheet, transparent heat-insulating film, transparent sunshade products and other products that…
