Research on self-cleaning organic Ti-Si compound material

This study applies the principle of silane coupling agent (SG-Si900) of alkane chain steric hindrance effect,using SG-Si900, tetrabutyl titanate and TEOS as the main raw materials synthesizes self-cleaning organic Ti-Si compound materials by hydrolysis, constant temperature polycondensation and distillation. To improve the comprehensive performance, we can adjust the synthesis temperature and some main reaction parameters, such as H2O/Si, SG-Si900/TEOS, Si/Ti. The experiment proves that the best preparation conditions of compound materials is at the synthesis temperature of 80 degrees C, the ratio of H2O/Si is 8, the ratio of Si/Ti is 9, the ratio of SG-Si900/TEOS is 1. The viscosity of the compound materials which were mutually soluble with water at any ratio is 40.9 S and the contact angle of water against composite films based glass which are made by pulling method is less than 5 degrees.
