| 摘 要： | 研究了动态硫化工艺条件和共混比对氟橡胶（ＦＫＭ）／ＥＰＤＭ共混物拉伸性能拉、热油老化性能和应力松弛性能的影响。结果表明：与直接静态硫化相比，动态硫化可避免两种硫化体系的相互影响；静态硫化共混物拉伸强度只有２ＭＰａ，而动态硫化共混物可达１０ＭＰａ以上；工艺条件对动态硫化共混物性能的影响不大；随共混物中ＥＰＤＭ用量的增大，共混物的热空气老化和热油老化性能均有所下降

| Abstract: | The influence of the dynamic vulcanizing conditions and blending ratio on the tensile strength,hot oil resistance and compression stress relaxation of the fluoro rubber/EPDM blends was investigated.The results showed that the interference of two curing systems in the static vulcanization of fluoro rubber/EPDM blend was eliminated by using dynamic vulcanization;the tensile strength of the statically vulcanized blend was only about 2 MPa,while that of the dynamically vulcanized blend could reach over 10 MPa;the vulcanizing conditions had little influence on the physical properties of blends;and the hot air and hot oil aging properties of blends decreased as the EPDM proportion in the blends increased. |
