In order to improve the high temperature resistant performance of traditional silicate inorganic adhesive,the new-type compound high temperature adhesive was prepared by sol-gel method with tetraethyl orthosilicate and zirconium oxychloride.Its thermal stability and bonding performance were studied by characterizing the structure,phase composition,heat change and appearance.The results showed that pH was of great influence on the sol-gel reaction process,and the optimal pH was 3.The preparation methods had ...
