摘要 金红石型二氧化钛是一种宽禁带的无机半导体材料,在可见-近红外波段有很高的光谱反射率。本文通过热处理、球磨等处理手段增大填料粒径及填料粒子在树脂体系中的分散度来提高涂层对太阳光的反射率。不同手段处理后的粉体在400~2 500 nm波长范围内的平均反射率提高了7%,将涂层置于阳光下照射,记录不同时间下的温度,处理过的粉体的涂层的温度比未处理过的粉体的涂层低2 ℃。

Abstract: 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
