摘要
比较了不同硫化体系(双酚硫化体系和过氧化物硫化体系)对氟橡胶FKM性能的影响,结果表明:过氧化物硫化体系硫化速度快,交联度大;老化前后,过氧化物硫化体系力学性能好,双酚硫化体系拉伸永久变形量优于过氧化物硫化体系的;双酚硫化体系起始外延分解温度、最大热分解温度、终止外延分解温度高于过氧化物硫化体系的。
The effects of different vulcanization systems(bisphenol vulcanization system and peroxide vulcanization system)on the performance of fluororubber FKM were compared.The results showed that the peroxide vulcanization system exhibited faster vulcanization rate and higher crosslinking degree.Before and after aging,the peroxide vulcanization system exhibited good mechanical performance,while the bisphenol vulcanization system demonstrated better tensile permanent deformation than the peroxide vulcanization system.The bisphenol vulcanization system exhibited higher initial epitaxial decomposition temperature,maximum thermal decomposition temperature and terminal epitaxial decomposition temperature than the peroxide vulcanization system.
