PP-g-MAH改性SGF+POE/FPP复合材料的制备及性能
Praparation and Properties of SGF+POE/FPP Composites Modified by PP-g-MAH
摘 要
采用型内二次发泡工艺制备了马来酸酐接枝聚丙烯(PP-g-MAH)共混改性短玻璃纤维+聚烯烃弹性体/发泡聚丙烯(SGF+POE/FPP)复合材料,考察了PP-g-MAH的含量对复合材料的泡孔形貌、微观结构和力学性能的影响.结果表明:PP-g-MAH的加入没有改变复合材料中的泡孔形貌,但改善了发泡效果,泡孔密度的增幅超过60%,且孔径分布均匀;SGF与基体间的界面结合得到增强,该复合材料的抗弯和抗压强度分别在PP-g-MAH的质量分数为5%和8%时达到最大值,而冲击韧度则随PP-g-MAH含量的增加逐步下降.

Abstract
The short glass fiber(SGF)+polyolefin elastomer(POE)/foamed polypropylene(FPP) composites co-modified with maleic anhydride grafted PP (PP-g-MAH) were prepared through post-foaming process.The effect of PP-g-MAH content on the cell morphology,microstructure and mechanical properties of composites was investigated.The results show that there was no obvious change on the cell morphology of the composites,but improvement in foaming effect was realized by the addition of PP-g-MAH with a 60% increase in cell density and the diameter uniform distributed.The interfacial bonding between SGF and matrix was enhanced.The flexural strength and compressive strength of the composites of the peak values could be obtained with 5wt% and 8wt% PP-g-MAH,respectively.The impact toughness declined gradually with the increase of the PP-g-MAH content.
