摘　　要： 为了获得高刚性和高韧性的玻璃纤维毡增强聚丙烯(GMT-PP),首先制备了硅烷接枝聚丙烯(PP-g-Si),研究了PP-g-Si对GMT-PP的增容作用及增容机理。结果表明质量分数低于20％的PP-g-Si,可以提高GMT-PP的拉伸和弯曲性能,而冲击强度几乎没有变化;PP-g-Si对GMT-PP的增容机理为PP-g-Si的甲硅烷基氧与结合在玻璃纤维上的氨基硅烷的氨基相互吸附形成了氢键。 For the balance between stiffness and toughness of polypropylene composites which filled by glass fiber mat, the compatibilizing mechanism and effect of silane grafted polypropylene on GMT-PP performed were studied. The results show that silane grafted polypropylene can improve the tensile and flexural properties of the composites with the mass content less than 20%, while the Izod impact strength almost remains the same. The compatibilizing mechanism of silane grafted polypropylene for GMT-PP lies in hydrogen bond between silane grafted polypropylene and amino silane.
