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。
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.
