再生橡胶基热塑性弹性体的制备

摘要

研究制备再生橡胶基热塑性弹性体.结果表明,以聚苯乙烯-乙烯-丁烯-苯乙烯(SEBS)为连续相、再生橡胶为分散相,选择配方:SEBS 70,再生橡胶 30,炭黑N330 10,氧化锌 3,硬脂酸 l,防老剂4010NA l.5,促进剂ZDC 0.5,促进剂TMTD 0.5,硫黄 0.5,可制得综合物理性能较好的再生橡胶基SEBS热塑性弹性体.%In this study,thermoplastic elastomer was prepared by using reclaimed rubber as dispersed phase and polystyrene-ethylene-butadiene-styrene (SEBS) as continuous phase.The optimized compositions were as follows:SEBS 70,reclaimed rubber 30,carbon black N330 10,zinc oxide 3,stearic acid 1,antioxidant 4010NA 1.5,accelerator ZDC 0.5,accelerator TMTD 0.5,and sulfur 0.5.
