【摘要】 系统总结了天然橡胶和三元乙丙橡胶相容性和共硫化性差的原因，从调节生胶共混比、增加增容剂用量、优选交联剂、改进共混工艺、对生胶进行化学改性和辐射硫化改性等角度较为全面地介绍了近年来在天然橡胶/三元乙丙橡胶并用胶共混改性方面的技术进展，并对天然橡胶和三元乙丙橡胶共混改性领域内未来的发展趋势进行了展望。更多还原

【Abstract】 The reason for poor compatibility and poor covulcanization of natural rubber and ethylenepropylene diene monomer was systematically summarized, and the technological development in blending modification of natural rubber/ethylene-propylene diene monomer blending rubber in recent years was comprehensively introduced from the perspective of the adjustment of the blending ratio of each raw rubber, the increase in compatibilizer dosage, the optimal selection of cross-linking agent,the improvement of blending process, and the che-mical modification and radiation vulcanization modification of raw rubber with 63 references. Finally, the future developing trend of blending modification of natural rubber/ethylene-propylene diene monomer was prospected.更多还原
