中文摘要:
      研究天然橡胶（NR）/三元乙丙橡胶（EPDM）体系并用比与粘度比的变化对其物理性能、耐老化性能及相态结构的影响。结果表明：分别调整NR和EPDM的硫化特性并使之保持一致时，可以改善NR/EPDM并用胶的共硫化性能；NR/EPDM体系粘度比不变，NR含量越大，呈连续相态，并用胶的耐老化性能越差；NR/EPDM体系并用比不变，EPDM粘度越低，容易成为连续相态，并用胶的耐老化性能明显提升。
英文摘要:
      The effects of blend ratio and viscosity ratio of NR/EPDM on the physical property，aging resistance and phase structure of the blend were investigated.The results showed that，the co-vulcanization of NR/EPDM blend could be improved by adjusting the curing characteristics of EPDM and NR.When the viscosity ratio of NR/EPDM blend was unchanged，with the addition level of NR increasing，NR formed the continuous phase and the aging resistance of the blend was reduced.When the blend ratio of NR/EPDM was unchanged，with the viscosity of EPDM decreasing，EPDM formed the continuous phase and the aging resistance of the blend was improved.
