玻纤增强茂金属聚乙烯弹性体改性聚丙烯的研究

摘要

采用短玻纤(SGF)对PP/茂金属聚乙烯弹性体(mPE)共混物进行增强，制得Pp/mPE/SGF三元共混复合材料，分别对Pp/mPE二元共混物和pp/mPE/SGF三元共混复合材料的力学性能进行了研究。探讨了弹性体用量、SGF的用量和表面处理对共混物和复合材料拉伸性能、低温冲击韧性和蠕变性能的影响。结果表明，Pp/mPE/SGF三元共混复合材料同时具有良好的刚性和韧性。%PP/mPE blend was reinforced with short glass fiber (SGF) to get PP/mPE/SGF temary composites. The tensile proper-ties, low temperature impact toughness and creep behavior of PP/mPE binary blends and PP/mPE/SGF temary composites were examined.The result shows that PP/mPE/SGF ternary composites have very high stiffness and toughness.
