Abstract

This study investigates the effects of different types of curatives at polypropylene (PP) and ethylene propylene diene monomer (EPDM) blend ratios (100 : 40 phr) in dynamically vulcanized products. The thermoplastic vulcanizates are prepared by batch melt mixing of PP with EPDM, using pheolic resin, dicumyl peroxide, hydrosilyation, and complex systems as curatives. Observed changes in curing characteristics and mechanical properties of blends have been correlated with phase morphology, as attested by scanning electron micrographs. On the basis of the obtained results, different curative systems control final vulcanizing characteristics, mechanical properties, morphology, intermolecular interaction, and thermal properties of EPDM/PP blends.

复合硫化剂对乙丙橡胶/聚丙烯共混物性能的影响

研究了不同类型的硫化剂对聚丙烯(PP)和乙丙二烯单体(EPDM)共混比(100:40 phr)下动态硫化产物的影响。采用酚醛树脂、过氧化二氨基、氢化硅油和复合体系作为硫化剂，将PP与三元乙丙橡胶分批熔融混合制备热塑性硫化胶。观察到的共混物的固化特性和力学性能的变化与相形态有关，扫描电子显微图证实了这一点。在得到的结果的基础上，不同的硫化体系控制EPDM/PP共混物的最终硫化特性、力学性能、形态、分子间相互作用和热性能。
