| 中文摘要: |
| 以氯化胶粉（CGRT）和聚氯乙烯（PVC）为主要原料制备CGRT/PVC共混物，并通过试验研究CGRT用量和氯质量分数、增塑剂DOP用量以及氯化聚丙烯改性CGRT对其物理性能的影响。结果表明：CGRT用量为20份且氯质量分数为0.08左右、增塑剂DOP用量为30～40份时，CGRT/PVC共混物的物理性能较佳；与CGRT/PVC共混物相比，改性CGRT/PVC共混物的拉伸强度、拉断伸长率、撕裂强度和冲击强度均有提高。 |
| 英文摘要: |
| The chlorinated ground rubber tire（CGRT）/polyvinyl chloride（PVC） blend was prepared，and the effect of some factors on the physical properties of CGRT/PVC blend was investigated experimentally，such as the addition level of CGRT and the mass fraction of chlorine，addition level of plasticizer DOP and modification of CGRT by chlorinated polypropylene.The results showed that，when the addition level of CGRT was 20 phr，the mass fraction of chlorine was around 0.08，and the addition level of plasticizer DOP was 40 phr，the physical properties of CGRT/PVC blend was better.With modification on CGRT，the tensile strength，elongation at break，tear strength and impact strength of blend could be increased. |
