The Antibacterial Property of La3+/ZnO Rare Earth Compound Antibacterial Imitation Porcelain Paint

La3+/ZnO composite antibacterial agent is made by the combination of Nano-ZnO and Rare Earth LaCl3 whose antibacterial properties are better than Nano-ZnO and Rare Earth LaCl3 themselves, that is, Nano-ZnO whose photocatalysis can be significantly improved by doping La3+,with the obvious coordination function. In this Paper, antibacterial agent was used to prepare the La3+/ZnO Rare Earth compound antibacterial imitation porcelain paint. At the same time, the influence of the antibacterial agent with different amounts and the major component in imitation porcelain paint to antibacterial property are discussed respectively. It shows that, when the antibacterial agent is mixed in the range of 8-9%,the antibacterial property of coating is very satisfactory, the major component of the imitation porcelain paint not only cause no influence on the antibacterial property of the compound antibacterial coating, but also enhances its water resistance and alkali resistance .
