摘要
为了充分利用农业剩余物资源、降低材料的成本,本文将麦秸纤维与聚丙烯复合制备绿色环保型材料,研究了硅烷偶联剂种类、麦秸纤维含量以及相容剂MAPP含量对材料力学性能的影响,采用扫描电镜、体视显微镜观察麦秸纤维的分散性以及材料的冲击断口形貌。结果表明:KH550或A151表面处理明显降低了麦秸纤维的极性,改善其与聚丙烯的相容性,提高了材料的力学性能;当麦秸纤维质量分数为25%左右时,在聚丙烯基体保持均匀分散,增强效果最佳;当MAPP质量分数为8%左右时,材料的拉伸、弯曲以及冲击强度均达到最大值。
To fully utilize the abundant agricultural residues and reduce the cost of material,environmentally friendly composite materials were prepared by compounding of wheat straw fiber and polypropylene.The effects of the kinds of coupling agent,the amount of wheat straw fibers and MAPP compatibilizer on the mechanical properties of material were studied.Dispersion of wheat straw fibers and surface morphology of impact fracture were observed by SEM and stereomicroscope.The results show that after wheat straw fibe...
