陶瓷釉面砖上制备TiO_2杀菌薄膜

TiO_2 Anti-bacteria Film Coated on the Glazed Tile Surface

采用溶胶—凝胶法 ,以钛酸四丁酯为先驱体 ,无水乙醇为溶剂 ,乙酰丙酮为稳定剂 ,Ag+ 为辅助杀菌剂 ,在陶质釉面砖上制备出TiO2 薄膜。经生物检测 ,其 8h杀菌率在 90 %以上。

TiO 2 anti bacteria film with aid anti bacteria agent Ag+ coated on the surface of glazed tile is prepared by sol gel method from precursor tetrabutyl titanate and with the solvent alcohol and stabilized agent acctyl acetone. The result of biology test shows that bacteria killed factor in 8hour is above 90%.
