SBR/PE/PVC多元共混体性能的研究 Ⅰ制备条件对共混体性能的影响

Study of SBR/PE/PVC Multi-component Blends Part Ⅰ.Effect of Prepartion Conditions on Mechanical Properties

介绍了开炼法制备SBR/PE/PVC多元共混体的共混温度、共混时间、交联体系及共混体高温返炼对材料力学性能的影响。实验结果表明,在适宜的条件下,共混体具有较好的力学性能,共混体经高温返炼后仍为性能较好的弹性体。

The effects of mixing temperature, mixing time, crosslinking agent systems and high temperature repeated mixing on the mechanical properties of SBR/PE/PVC blends were studied. The experimental results showed that the blends had good mechanical properties and that the blends remained elastomers after they had been repeatedly mixed at high temperature.
