【摘要】 制备了硅烷接枝聚丙烯(PP-g-Si),研究了PP-g-Si作为PP/GF体系的界面相容剂对界面结合和力学性能的影响,并与马来酸酐接枝聚丙烯(PP-g-MAH)的增容效果进行了比较。结果表明,PP-g-Si对PP/GF体系有增容作用,PP-g-Si不仅可以改善PP/GF复合体系的拉伸强度,而且可以改善PP/GF复合体系的韧性;PP-g-Si的增容效果优于PP-g-MAH。更多还原

【Abstract】 Silane-grafted polypropylene(PP-g-Si)was prepared by means of reactive grafting process and used as the coupling agent for polypropylene/glass-fiber(PP/GF)composites.The effect of PP-g-Si on the interaction and mechanical properties of the composite was studied and compared with that of maleic anhydride grafted polypropylene(PP-g-MAH0.The results showed PP-g-Si had compatibilization effect on PP/GF and the effect was better than that of PP-g-MAH.更多还原
