摘　　要：采用四氯化钛为原料合成TiO2纯水性溶胶,将TiO2溶胶和硅丙乳液通过加热、温度控制等制备了水性光催化自洁涂层液。在TiO2溶胶质量分数为10%～20%时,该液体在基板上形成的涂层具有很好的超亲水特性,在UV光照射30～60min或阳光照射2～5h后,亲水角可低至4°左右,涂层表面呈现自洁特性。Titanium oxide sol was prepared by using titanium tetra-chlorid e.Water-photocatalysis self-cleaning coating was prepared with TiO 2 sol and silicopropane emulsion by heating and temperature control.When weig ht percentage of TiO 2 sol was10%-20%,the coating showed a good hydrophilicity after UV irr adiation for30～60min or sunlight irradiation for2～5hours.The hydrophil ic angle lowered to about 4degree and the surface of coated layer had the featu re of self-cleaning.
