摘　　要：介绍了缩合型室温硫化(RTV)硅橡胶的热老化机理,综述了提高缩合型RTV硅橡胶耐热性的主要方法:改变主链和侧基结构、使用新型硫化交联体系、加入添加剂以及其它方法,并指出了提高缩合型RTV硅橡胶耐热性的研究发展方向。The high temperature aging mechanism of condensed room temperature vulcanized （RTV） sili- cone rubber was summarized. Various modification methods, such as modifying the structure of main chain and side group, designing and developing a new type of vulcanized crosslinking system, adding new additives, among others for improving the thermal stability of the condensed RTV silicone rubber were reviewed. The pa- per also discussed the development trend for improving the thermal stability of condensed RTV silicone rubber.
