摘要:
为比较不同改性剂对填充聚丙烯用玻璃纤维表面改性的优劣及改性剂的最佳用量,使用熔融共混法研究了两种硅烷偶联剂、钛酸酯偶联剂以及马来酸酐接枝聚丙烯改性玻璃纤维对玻璃纤维填充聚丙烯复合材料的力学性能的影响.并用扫描电子显微镜观察了几种不同的表面处理对聚丙烯/玻璃纤维复合材料断面形貌影响.结果表明,所使用的几种改性剂都能改善聚丙烯的力学强度和模量.扫描电镜照片显示聚丙烯与玻璃纤维间的界面相互作用的强弱与聚丙烯/玻璃纤维复合材料的力学性能之间有着紧密的关系.此外,力学数据结果表明,使用8% 的马来酸酐接枝聚丙烯相容剂对聚丙烯/玻璃纤维复合材料的增强效果最佳,硅烷偶联剂的效果次于马来酸酐接枝聚丙烯,钛酸酯偶联剂的改性效果最差.
Abstract:
Melt blending method were used for preparing polypropylene/glass fiber blends. Four kinds of modifiers such as silane coupling agent KH-550 and KH-580, aluminate coupling agent and maleic anhydride grafted polypropylene(MAPP) were used to modify the surface of glass fiber. The best modifier and its optimum dosage were obtained by testing the mechanical properties. The effect of different surface treatment on the fractured surfaces morphologies of polypropylene/glass fiber composites was observed by scanning electron microscope. The results show that the surface treatment of glass fiber improves the mechanical strength properties of polypropylene/glass fiber composites. Scanning electron microscopy photos reveal that the interfacial interaction of glass fiber and polypropylene is closely related with the final mechanical properties of polypropylene/glass fiber composites. In addition, the mechanical properties of the composites indicate that when 8% MAPP is used as compatibilizer, the reinforcing effect on polypropylene matrix is best, followed by the silane coupling agent and the aluminate coupling agent.
