| 摘 要： | 为改善聚氯乙烯(PVC)防水卷材的性能,用不同组分的氯化聚乙烯(PE-C)与PVC共混,并用邻苯二甲酸二辛酯(DOP)作为增塑剂进行改性.结果表明,随着PE-C、DOP含量的增加,PVC防水卷材的拉伸强度、硬度单调减小,其中拉伸强度最低减小47.6%,硬度最低减小9.8%;断裂伸长率和熔体流动速率单调增加,最大增加值分别为62%、644%.比较不同组分试样的拉伸曲线发现,DOP含量为20 g,PVC、PE-C配比为70/30时,其拉伸曲线有屈服现象产生;但PE-C含量对拉伸曲线的形态无影响,无屈服现象.扫描电子显微镜照片从微观形态上验证了实验结果的合理性.

| Abstract: | Chlorinated polyethylene (PE-C) was blended with polyvinyl chloride(PVC) at the different ratios to improve the performance of the traditional PVC waterproof rolled sheet,while 2-dioctyl phthalate(DOP) was used as a plasticizer. The properties of the modified PVC waterproof rolled sheet,including tensile strength,elongation at break,melt flow rate(MFR) and shore hardness number,were experimentally studied. It was found that when the contents of PE-C and DOP increased,the tensile strength and hardness decrea... |
