摘要:
采用固相接枝方法合成了马来酸酐接枝改性聚丙烯（PPgMA），以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SEM、电子拉力机和氧指数测定仪等研究了PPgMA对复合材料的微观结构、力学性能和阻燃行为的影响.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，从而提高了复合材料的冲击性能和阻燃性能.
Abstract:
Polypropylene (PP) grafted with maieic anhydride was performed via solidstate modication method. PP/nanomagnesium hydroxide (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, mechanical properties and flame retarding behaviours were characterized by SEM, tensile measurements and limiting oxygen index. 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 unnotched impact strength of PP/PPgMA/MH composites were significantly enhanced by introduction of PPgMA. The flame retardant of PP/PPgMA/MH and PP/MH composites can also be improved at 40 wt% loading of MH.
