有机过氧化物动态硫化HPVC/SBR共混体系力学性能的研究

Study on Mechanical Properties of Dynamically Cured HPVC/SBR Blend with DCP

采用有机过氧化物硫化体系，通过动态硫化方法制备高聚合度聚氯乙烯（ＨＰＶＣ）／ＳＢＲ共混型热塑性弹性体，测试共混物硫化胶的力学性能。结果表明，当ＨＰＶＣ／ＳＢＲ并用比为８０／２０，过氧化二异丙苯（硫化剂ＤＣＰ）用量为１５份时，加入１～３份不同种类的相容剂，可改善共混物的力学性能，其中以氯化聚乙烯（ＣＰＥ）的作用效果最好；

The HPVC/SBR blends were prepared by dynamic vulcanization with DCP.The mechanical properties of the blend vulcanizates were determined.The results showed that the improved mechanical properties of blends were obtained when HPVC(80)/SBR(20),1.5 phr of DCP,and 1～3 phr of different kinds of compatibilizers were used,and the best result was obtained when CPE was used as compatibilizer;and the remilling number didnt have significant effect on the mechanical properties of blends.
