二氧化钛颜料表面包覆及光活性评价研究进展
Research progress on the surface coating and photo-activity evaluation of titanium dioxide pigment
摘要
Abstract
Titanium dioxide(TiO2)is an important white pigment,which is widely used in paint, plastic,paper and rubber industries. However,TiO2 is able to catalyze the degradation of organic matrix under UV light,which causes unfavorable results in properties,such as discoloration,cracking, and chalking. This photo-catalytic behavior seriously limits the utilization of titanium dioxide in organic coatings. Hence,the surface coating and photo-activtiy evaluation of TiO2 is necessary and important. In this paper,surface treatment of inorganic or organic on TiO2 was reviewed. In detail,the evaluation methods of photo-activity of titanium dioxide pigment were also introduced,and the advantages and disadvantages of the methods were summarized. The realization of the controllable, efficient and targeted coating on TiO2surface,and the development of the reliable,applicable and rapid method to assess the photo-activity of TiO2 pigment will be main research directions in this field.关键词
