摘要
通过熔融共混制备聚丙烯(PP)/马来酸酐接枝聚丙烯(PP-g-MAH)/滑石粉(Talc)/环氧树脂(EP)复合材料,研究了E-51/504/554(55.6/42.4/2,E1)、E-51/EDA/554(92.2/7.8/0.01,E2)、E-20/2E4MZ(100/4,E3)三种EP体系及其含量对复合材料力学性能的影响,结果表明,E-1对复合材料的弯曲模量改善最显著,当加入4%的E1时,复合材料的弯曲模量达到最大值,提高了29.1%。傅里叶红外光谱(FT-IR)分析表明,EP与PP-g-MAH发生了酯化反应。观察复合材料的微观结构,发现EP阻止Talc的凝聚,加强了两相界面作用力。
Polypropylene （ PP ）/maleie anhydride-grafted polypropylene （ PP-g-MAH ）/talc/epoxy （ EP ） composites were prepared in a eorotating twin-screw extruder. The effects of epoxy systems including E-51/504/554 （55.6/42.4/2, El）, E-51/EDA/554 （92.2/7.8/0.01, E2） and E-20/2FAMZ （100/4, E3）, and their epoxy contents on the mechanical properties of the composite were investigated. The results show that the most significant improvement of the bending modulus of the composites is obtained when E1 is added. When the E1 content is 4 %, the bending modulus of the composites is the largest among all investigated cases, and it is improved by 29.1%. The Fourier transform infrared spectrum （FT-IR） reveals that the esterification reaction between the epoxy group and MAH group in PP-g-MAH has taken place. The morphological study of composites by scanning electron microscopy （SEM） shows that the agglomeration of tale is prevented, and the interracial force is enhanced by epoxy resin.
