摘　　要：采用模压化学发泡法制备不同共混比橡胶型氯化聚乙烯(CM)/聚乙烯-辛烯弹性体(POE)发泡材料,研究其泡孔结构和物理性能。结果表明:不同共混比CM/POE发泡材料均具有闭孔结构;随着POE用量增大,共混发泡材料的泡孔直径先减小后增大,泡孔由扁平塌陷不均匀分布变为富有立体感的均匀分布,泡孔壁增厚,邵尔C型硬度和压缩强度增大,拉断伸长率减小,100%定伸应力和拉伸强度先增大后减小,回弹值轻微波动。The CM/POE blend foaming materials with different blending ratios were prepared by molded chemical foaming,and the cell structure and physical properties were investigated. The results showed that,the CM/POE blend foaming materials with different blending ratios all had a closed-cell structure. With the increase of the addition level of POE,the cell diameter of foaming material decreased first and then increased,the cell structure changed from flat and nonuniform distribution to uniform three-dimensional distribution,the cell wall became thick,the Shore C hardness and compression strength were increased,elongation at break was decreased,modulus at 100% elongation and tensile strength were increased first and then decreased,and the resilience value fluctuated slightly.
