摘要
综述了硅橡胶的热氧老化机理,金属化合物对聚硅氧烷侧链氧化的抑制作用。讨论了金属氧化物、金属羧酸盐、含金属的有机硅聚合物对硅橡胶耐热性能的影响,指出了各类金属化合物的应用范围及发展方向。
The mechanism of the thermo-oxidative aging of silicone rubber and the inhibition of metallic compounds on the oxidation degradation and the crosslinking of side chains of polysiloxane were summarized in this paper. The effect of metal oxides,metal carboxyiate and polysilicone containing metal ions on the heat-resistance of silicone rubber was discussed. The range of application and the direction of development of metallic compounds were also pointed out.
