摘要:
利用动态交联技术制备了动态交联聚丙烯/乙烯\|辛烯共混物（PP/POE）.采用哈克转矩流变仪研究了动态交联对PP/POE共混物扭矩的影响；研究了交联剂的种类和POE用量对共混物力学性能的影响；考察了动态交联共混物的流变性能.结果表明，加入过氧化二异丙苯（DCP）后，PP/POE共混物的扭矩先升后降至平衡状态； 随着POE用量的增加，PP/POE共混物的冲击强度明显提高，但拉伸强度有所降低，PP/POE共混物合适配比为100∶40，DCP的添加量为POE含量的2％为优；PP/POE共混物熔体流变行为属于假塑性流体，且高温下（220 ℃）降解反应程度高于交联反应程度.
Abstract:
Dynamic crosslinked polypropylene/ethylene\|octene copolymer (PP/POE) blends were prepared by using dynamic crosslinked method.The torque of PP/POE blends was studied using a Hakke Rheometer. Effect of the amount of DCP and POE on mechanical properties and rheological properties of dynamic crosslinked PP/POE blends was investigated. The results show that the torque of PP/POE blends increases firstly with increasing DCP and then decreases to the balance;the impact strength of the blends increases obviously, but tensile strength decreases slightly with increasing POE content;the suitable proportion of PP/POE is 100∶40, and the optimal amount of DCP is 2% of POE content; the rheological behavior of dynamic crosslinked PP/POE blends belongs to pseudoplastic fluid, the degree of degradation reaction is higher than that of crosslinking reaction at high temperature of 220 ℃.
