摘要
研究了两种交联工艺、交联剂用量及助增韧剂PE的引入对PP/POE共混体系材料力学性能的影响。实验结果表明:聚丙烯的交联改性宜采用两步法工艺,PP/POE共混体系加入交联剂能进一步提高韧性和刚性;助增韧剂PE与POE配合使用具有协同增韧效应。
The effect of two cross-linking process, cross-linking agent amount and the adding of PE plasticizing agent promoter on material mechanics of PP/POE blending system were studied. Experiment result indicated that the two- step process should be taken for cross-linking modification and adding cross-linking agent to PP/POE blending system could improve toughness and rigidity further. Use of PE plasticizing agent promoter together with POE could have coherent effect to plasticize.
