摘要
首先研究了不同含量的纳米SiO2对聚丙烯(PP)力学性能的影响,通过综合分析选出最佳配方。还比较了马来酸酐接枝PP(PP-g-MAH)、马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)、马来酸酐接枝PE(PE-g-MAH)对SiO2/PP共混体系力学性能和流动性的影响;最后研究了未接枝POE和POE-g-MAH的配比对SiO2/PP共混体系力学性能的影响。结果表明,SiO2质量分数为8%时混合体系性能较佳;单纯添加接枝POE比添加POE/POE-g-MAH的增韧效果更好,当POE和POE-g-MAH同时使用时,控制一定比例能使二者在增韧上具有协同作用。
The effects of different nano-SiO2 contents on mechanical properties of polypropylene were studied, a comprehensive analysis on the best formula was found out; Comparison of effect of MAH grafted PE, PP and POE on mechanical properties and fluidity of SiO JPP blends was studied ; Effect of non-grafted POE and graft POE-g-MAH ratio on mechanical properties of SiO 2/PP blends was researched. Studies showed that： 8% SiO2 hybrid had a better system performance; than adding POE/POE-g-MAH. When non-grafted POE adding grafted POE had a better toughening effect and grafted POE were used at the same time, a certain percentage could make both in the perspective way of toughening and synergy.
