中文摘要:
      研究了白炭黑用量对环氧化天然橡胶(ENR)流变性能、弹性记忆、硫化特性、平衡应力-应变及动态力学性能的影响。试验结果表明：白炭黑填充的ENR属非牛顿型流体；随着白炭黑用量增加，挤出膨胀减小，硫化速度加快，滞后增大；随着剪切速率增大，挤出膨胀增大。透射电镜照片表明硅烷偶联剂使白炭黑在ENR中的分散性明显提高。
英文摘要:
      The influence of silica level on the rheology，elastic memory，curing behaviour，equilibrium stress-strain and dynamic mechanical properties of siliea-reinforced ENR was studied.The test result showed that silica-reinforced ENR was a non-Newtonian fluid；the extrusion swelling decreased，the vulcanization rate and the hysteresis 1oss increased as the level of silica increased；the extrusion swelling increased as the shear rate increased.It was indicated with TEM that the dispersion of sillca in ENR compound improved significantly when a silane coupling agent was added into the compound.
