摘　　要：通过共聚氟硅橡胶与PS树脂共混对混炼胶性能的影响进行尝试性研究。分析了PS树脂的添加量和共混工艺对混炼胶性能的影响,得出结论:PS树脂对共聚氟硅橡胶有增强作用,尤其是加入少量硫化剂进行动态硫化,可以提高共混物的拉伸强度,达到对共聚氟硅橡胶增强的效果。动态硫化温度对共混物的性能影响较大。In this paper, the influence of the amount of polystyrene （PS） and the arts and crafts of blending on the properties of methyl （3,3,3-trifluoropropyl） siloxane-dimethyl siloxane copolymer （SKTFT-25） was explored. The reinforcement of SKTFT-25 by the blending of PS and SKTFT-25 was investigated. The experiment showed that the PS can reinforce the SKTFT-25 and the tensile strength can be reinforced by dynamically vulcanizing with a few sulfidizer. The influence of the temperature of dynamically vulcanizing on the properties of SKTFT-25/PS blending was also discovered.
