摘要 采用二元乙丙橡胶接枝马来酸酐(EPM-g-MAH)及玻璃纤维(GF)对聚酰胺6(PA6)进行共混改性,并对复合材料的力学性能和微观结构进行了表征。结果表明:PA6/EPM/EPM-g-MAH复合材料的形态结构得到明显改善,弹性体分散相粒径细化且分布均匀;增韧PA6所用的EPM-g-MAH适宜的粒径范围是0.2~0.7μm;当PA6/EPM/EPM-g-MAH/GF为80/10/10/(30~40)时,复合材料的缺口冲击强度可达到25.4 kJ/m2,拉伸强度可达到73 MPa。 PA6 was modified with ethylene propylene rubber grafted maleic anhydride (EPM-g-MAH) and glass fiber (GF). The mechanical properties and micromorphology of the composite were characterized. The results show that EPM-g-MAH can improve the miscibility between PA6 and EPM obviously, decrease the particle size of dispersion phase and make the dispersion of the dispersion phase more uniform. The optimal size range of elastomer particles is 0.2-0.7 μm when PA6 is toughened by EPM-g-MAH. When PA6/EPMIEPM.g-MAHIGF=80110/IO/(30-40), the impact strength and tensile strength of the composite are 25.4 kJ/m^2 and 73 MPa respectively.
