摘要
本文通过冲击实验，拉伸实验，动态力学分析（ＤＭＡ）及扫描电镜（ＳＥＭ）的观察，研究了ＥＶＡ增容的ＰＶＣ／ＳＢＳ共混体系的性能与形态结构的关系。研究结果表明，ＥＶＡ对ＰＶＣ／ＳＢＳ有良好的增容作用，并且与ＳＢＳ一起对ＰＶＣ有协同增韧效果。
The properties and morphology of PVC/EVA-SBS blend were studied by impact testing,stress-strain behavior, dynamic mechanical analysis (DMA), scanning electron microscopy (SEM). The relationships between properties and morphology of PVC/EVA-SRS blends were discussed. Experimental results indicate that EVA is a good compatibilizer for PVC/SBS blends and the impact strength of the blends is obviously improved due to the synergitic toughening of EVA and SBS.
