摘　　要：利用开放式塑炼机和平板硫化机制备了聚乙烯/废天然橡胶的共混物。研究了聚乙烯/废天然橡胶(60/40)中硫磺加入量对共混物的拉伸强度、伸长率、熔体流速性能的影响。试验结果表明:当聚乙烯/废天然橡胶(60/40)时,硫磺加入1.0份时其综合性能最佳,共混物的拉伸强度达到9.3MPa,断裂伸长率为344%,熔体流动速率为0.25g/10min。Polyethylene（PE）/waste natural rubber（WNR）（60/40）blends were prepared by using a two-roll mill and a hydraulic press.The influences of different amount of sulfur on tensile strength,elongation and melt flow rate of PE/WNR blend were investigated.The experimental results showed that tensile strength reached the 9.3MPa,elongation at break was 344% and melt flow rate was 0.25g/10 min when added sulfur was 1.0phr（per hundred）in PE/WNR blend.
