摘要
聚硅氮烷(PSN)与羟基封端的聚二甲基硅氧烷反应,可制备硫化硅橡胶.在空气和氮气中,利用热重分析法和动力学分析方法,对硫化胶的热稳定性进行了研究.结果表明,PSN既可改进硅橡胶的热氧化性能,又可提高其在氮气中的耐热性能.
The silicone rubber vulcanizate was prepared by the reaction of polysilazane and terminal hydroxyl polydimethylsiloxane . The thermal stability of the vulcanizate in air and nitrogen was studied by thermogravimetry and kinetic analysis . The result showed that polysilazane could effectively improve the thermal stability of silicone rubber vulcanizate in air and nitrogen .
