| 摘 要： | 以麦秸纤维为增强材料、聚丙烯为基体物质、马来酸酐接枝聚丙烯（MAPP）为改性剂，制备麦秸纤维-聚丙烯复合材料。利用DMA、DSC、TG和SEM，探讨了MAPP的添加量（质量百分比1%、2%、5%、10%）和麦秸纤维形态（9、9～28、28～35、35目）对麦秸纤维 聚丙烯复合材料的热力学性能和结晶性能的影响。结果表明:①当MAPP的添加量为2%时，麦秸纤维-聚丙烯复合材料的储能弹性模量减小；当MAPP的添加量增加到5%、10%时，复合材料的储能弹性模量增加。②在麦秸纤维-聚丙烯体系内添加MAPP后，麦秸纤维 聚丙烯复合材料的结晶温度提高约1℃，结晶度增加了4%～8%；麦秸纤维以28～35目的形态作为聚丙烯基体的增强材料时，其复合材料的结晶温度为122.7℃，结晶率达到45.8%。③麦秸纤维-聚丙烯复合材料的热分解峰温分别为355和460℃。④麦秸纤维以纤维束的形态分布在基体聚丙烯中起增强作用，在整个体系内，麦秸纤维局部团聚且断裂明显。添加MAPP后，有利于基体物质在麦秸纤维表面的均匀覆盖。

| Abstract: | Composites of polypropylene (PP) and wheat straw fiber (9,28,35 mesh) modified by maleic anhydride polypropylene (MAPP,1%,2%,5%,10%,weight percentage) were prepared,and the dynamic flexural mechanical,thermal properties and surface morphology of wheat straw fiber-PP composites were investigated by dynamic mechanical analysis (DMA),differential scanning calorimeters (DSC),thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). With incorporation of 2% MAPP,wheat straw fiber-PP composites s... |
