纳米TiO_2改性外墙涂料的研究

Research of NanoTiO_2-modified Exterior Wall Coatings

采用表面活性剂、机械分散和超声波分散等工艺,将纳米TiO2分散到传统外墙涂料中,并对其性能进行了研究。结果表明,在传统涂料中添加涂料总质量0.5%的纳米TiO2,可明显提高涂料的综合性能。讨论了纳米TiO2的用量及其与乳液的适应性问题。

The nano -TiO2 power is dispersed into traditional exterior wall coatings by surface -active agent, super shear instruments and ultrasonic dispersions, the properties of the coatings are studied. The experiments show that the overall properties of the coatings are evidently improved with addition of 0.5% wt dispersed nano - TiO2 powders. This paper discussed the suitable dosage of nano - TiO2 and its adaptability to the latex.
