中文摘要:
      研究预处理芳纶浆粕对丁腈橡胶（NBR）性能的影响。结果表明：随着芳纶浆粕用量的增大，NBR胶料的焦烧时间呈缩短趋势，MH逐渐增大，硫化胶的硬度和50%定伸应力增大，拉断伸长率减小，撕裂强度先增大后减小，耐油性能提高，剪切储能模量增大；加入芳纶浆粕的硫化胶热稳定性优于未加芳纶浆粕的硫化胶；预处理芳纶浆粕在NBR中分散均匀。
英文摘要:
      The influence of pre-treated PPTA-pulp on the properties of NBR compound was investigated.The results showed that，as the addition level of PPTA-pulp increased，the scorch time of NBR compound tended to shorten，the MH increased gradually，the hardness and modulus at 50% elongation of the vulcanizates increased，the elongation at break decreased，the tear strength increased at first and then decreased，the oil resistance was improved，and the shear storage modulus increased.The thermal stability of the vulcanizates with PPTA-pulp was better than that without PPTA-pulp.The pre-treated PPTA-pulp was uniformly dispersed in NBR.
