摘　　要：采用氟橡胶接枝乙烯基三乙氧基硅烷(FKM-g-VTEO)作为增容剂,制备性能良好的氟橡胶(FKM)/硅橡胶(MVQ)共混物。研究增容剂用量对FKM/MVQ共混物力学性能、高温压缩永久变形和耐油性能的影响,并采用动态机械热分析仪(DMA)对共混物进行表征。结果表明,随着增容剂用量的增加,共混物的力学性能提高,高温压缩永久变形降低,耐油性能改善。DMA分析结果表明,增容剂对FKM/MVQ共混物具有明显的增容作用。The fluororubber（FKM） and silicone rubber（MVQ） blends were prepared using fluororubber graft vinyltriethoxysilane（FKM-g-VTEO） as a compatibilizer.The effects of FKM-g-VTEO amount on the mechanical properties,the compression set and the oil-resistant properties of FKM/MVQ blends were studied.FKM/MVQ blends were characterized by dynamic mechanical thermal analyser（DMA）.The results show that the mechanical properties of the blends are enhanced,the compression set decreases and the oil-resistant properties are improved with the increase of FKM-g-VTEO amount.The DMA results indicate that FKM-g-VTEO amount has distinct compatibilization effect on FKM/MVQ blends.
