  • Based on the morphology and particle size analyses of nano-TiO2 by transmission electron microscopy (TEM), the nano-TiO2 was respectively made into latex paint, automobile paint, furniture paint and anti-corrosion paint to investigate the weather resistance and optically variable property. The results show that the rutile nano-TiO2 can greatly improve the weather resistance, water resistance, alkali resistance and washing resistance of latex paint, and can also improve the weather resistance of furniture paint and anticorrosive paint. The automobile paint containing nano-TiO2 and aluminum powder has optically variable property, and the particle size of TiO2 has a great influence on the optically variable property. The aluminum paint modified by the ordinary TiO2 with an average particle size of 280 nm has no optically variable effect, while it has significant optically variable property with 35 nm TiO2 as the modifier. And the color difference from various angles increases with increase in the addition of the nano-TiO2.
