| 中文摘要: |
| 讨论了橡塑共混比、填料用量等因素对乙烯-醋酸乙烯共聚物（EVA）改性PE共混物力学性能和流变性能的影响。试验结果表明，EVA弹性体的加入降低了共混物的拉伸强度，提高了扯断伸长率及共混物熔体的流动性；活性碳酸钙的加入使共混物的拉伸强度、扯断伸长率和流动性下降；HDPE的加入提高了共混物的拉伸强度，但扯断伸长率和流动性下降。 |
| 英文摘要: |
| The influence of the blend ratio and the filler level on the mechanical and rheological properties of PE/EVA blend was investigated. The results showed that the tensile strength decreased，and the elongation at break and the melt flow property improved by the addition of EVA to the blend；the tensile strength，the elongation at break and the flow property decreased by the addition of active calcium carbonate；the tensile strength increased，and the elongation at break and the flow property decreased by the additon of HDPE. |
