| 摘 要： | 以马来酸酐接枝改性聚丙烯(PP-g-MA)作为界面改性剂制备了PP/PP-g-MA/纳米氢氧化镁(MH)复合材料。采用扫描电子显微镜(SEM)和毛细管流变仪研究了PP-g-MA对复合材料微观结构和流动性能的影响。结果表明:PP-g-MA的加入充当了MH粒子与PP基体的界面层,改善了两者的界面相互作用,提高了纳米MH粒子在PP中的均匀分散性,从而显著改善PP/MH复合体系的流动性能。

| Abstract: | Polypropylene/nano-magnesium hydroxide(PP/MH) composites with maleic anhydride grafted polypropylene(PP-g-MA) as an interfacial compatilizer were prepared by melt extrusion compounding and injection molding.The morphological structure and rheological behaviours were characterized by SEM and apillary rheometer.The results of SEM showed that the introduction of PP-g-MA could get more even distribution of the nano-MH in PP matrix.Compared to the PP/MH composites,the unnotched impact strength of PP/PP-g-MA/MH c... |
