中文摘要:
      分别采用酚醛树脂(PF)、硫磺(S)与双“2, 5”硫化剂(DBPH)作交联剂,研究了甲基丙烯酸缩水甘油酯接枝三元乙丙橡胶(EPDM-g-GMA)的动态硫化对聚对苯二甲酸乙二醇酯(PET)性能的影响。结果表明,采用PF硫化体系且其用量为0.6%、PET和EPDM-g-GMA质量比为70/30的合金的综合性能较好,其冲击强度较PET、未硫化PET/EPDM-g-GMA合金分别提高了594%和66%,拉伸强度较未硫化的PET/EPDM-g-GMA提高了19%。动态硫化还提高了PET/EPDM-g-GMA合金的热稳定性、PET的结晶温度和结晶速率。
英文摘要:
      Using phenolic resin (PF), sulfur (S) and 2,5-dimethyl-2,5-di(tert-butylperoxy) hexane (DBPH) as crosslinking agent, the effects of dynamic vulcanization of glyceryl methacrylate grafted ethylene-propylene-diene rubber (EPDM-g-GMA) on properties of polyethylene terephthalate (PET) were studied. The results show that the dynamically vulcanized PET/EPDM-g-GMA (70/30) blend with PF curing system and curing agent content of 0.6% possesses superior properties. Its notched impact strength is higher than those of neat PET and unvulcanized PET/EPDM-g-GMA (70/30) blend by 594% and 66%, respectively, and its tensile strength is higher than that of unvulcanized PET/EPDM-g-GMA by 19%, which is due to the improved compatibility between PET and EPDM-g-GMA via dynamic vulcanization. Moreover, thermal stability of PET/EPDM-g-GMA blends, crystallization temperature and crystallization rate of PET are also improved because of dynamic vulcanization.
