| 摘 要： | 在过氧化二异丙苯(DCP)引发下,研究三烯丙基异氰脲酸酯(TAIC)对聚丙烯(PP)的交联改性,比较单纯DCP和DCP/TAIC交联体系对PP熔体强度及其发泡性能的影响。加入TAIC前后,分别对PP的抗熔垂能力和熔体流动速率、PP发泡材料的凝胶率和力学性能进行测定。结果表明,与单纯DCP相比,DCP/TAIC交联体系对PP熔体强度的改善效果较好,而且相应的发泡材料具有较高的拉伸强度和直角撕裂强度,同时,偏光显微镜观察结果表明,经DCP/TAIC交联后的PP发泡材料表面更为光滑、泡孔细密且均匀一致。

| Abstract: | The polypropylene(PP) foamed material was prepared by the compression molding method using dicumyl peroxide (DCP) as initiator and triallyl-isocyanurate (TAIC) as coagent,and all ingredients were adequately plasticized in the mixing chamber. In the absence and presence of TAIC,the anti-sagging ability and melt flow rate of polypropylene,the mechanical properties and the gel percentage of foamed PP were measured,respectively. The results indicate that the degree of crosslinking and the melt strength of PP ar... |
