Titanium dioxide is a kind of inorganic semiconductor material which has a large energy gap, meanwhile, has high visible and near infrared spectral reflection. The heat treatment, ball milling and other treatment are used to increase the particle size and the dispersibility of filler particles in the resin system. Within the different treatment of the powder, the reflectivity of the powder in 400~2 500 nm wavelength has increased for 7%. When the coating is placed in the sun, its temperatures at different times are recorded, indicating that the coating based on the treated powders is 2 ℃ lower than that based on the untreated powders.
Key words: titanium dioxide; spectral reflection; heat treatment; ball milling; dispersibility
