中文摘要:
      研究橡胶并用比及相容剂离子化热塑性弹性体对三元乙丙橡胶（EPDM）/丁腈橡胶（NBR）并用胶性能的影响。结果表明：未加入相容剂时，随着EPDM/NBR并用比减小，并用胶的100%定伸应力和拉伸强度呈增大趋势，耐热氧老化和耐臭氧老化性能下降，耐油性能提高，EPDM与NBR的相容性较差；加入相容剂离子化热塑性弹性体后，并用胶的硬度、拉伸强度、撕裂强度和弹性能提高，EPDM与NBR的相容性显著改善。
英文摘要:
      The effects of rubber blending ratio and compatibilizer ionic thermoplastic elastomer on properties of EPDM/NBR blends were studied.The results showed that，when the compatibilizer was not added，the modulus at 100% elongation and tensile strength of blends increased with EPDM/NBR blending ratio decreasing，and the heat oxygen aging resistance and ozone aging resistance decreased，the oil resistance was improved，and the compatibility between EPDM and NBR was poor.After adding the ionic thermoplastic elastomer，the hardness，tensile strength，tear strength and elasticity of EPDM/NBR blends increased，and the compatibility between EPDM and NBR was improved significantly.
