摘要
采用动态硫化法制备SBR／高抗冲聚苯乙烯（HIPS）热塑性硫化胶（TPV），并对其性能进行研究。结果表明，当SBR／HIPS共混比大于60／40时，SBR／HIPSTPV呈现出典型的弹性体应力-应变行为；当SBR／HIPS共混比为60／40-70／30时，SBR／HIPSTPV的硬度适中，综合物理性能良好。扫描电子显微镜分析表明，SBR以带状形貌均匀分散在HIPS基体中，两相界面结合良好。
A SBR/high impact polystyrene （HIPS） thermoplastic vulcanizate （TPV） was prepared by dynamic vulcanization, and its properties were investigated. The results showed that, when the blending ratio of SBR/HIPS was higher than 60/40, the SBR/HIPS TPV displayed typical stressstrain behavior of an elastomer;when the blending ratio of SBR/HIPS was 60/40-70/30, the hardness of SBR/HIPS TPV was suitable, and the comprehensive physical properties were good. It was found by SEM that the strip-like SBR was uniformly dispersed in the HIPS matrix,and the interracial adhesion between SBR and HIPS was good.
