摘要:
以正硅酸乙酯(TEOS)为主要原料,乙醇为溶剂,盐酸或氨水等为催化剂可制得硅酸凝胶.探讨了溶胶凝胶反应的机理及催化剂、水、溶剂及反应温度等对胶凝时间、凝胶的黏度、结构等的影响.采用先酸性后碱性的两步Sol-Gel法可大大缩短胶凝时间.
Abstract:
Ethyl orthosilicate (TEOS) is used as the main raw material, ethanol as solvent, hydrochloric acid or ammonia as catalyst to prepare silicate gel. The mechanism of sol-gel reaction and the effects of catalyst, water, solvent and reaction temperature on gelling time, viscosity and structure of gel were discussed. The two-step Sol-Gel method of first acidic and then alkaline can greatly shorten the gelling time.
