| 摘 要： | 采用反应挤出技术制备了尼龙66/弹性体/玻璃纤维三元复合材料。对三元复合材料的冲击强度、熔体流动速率、吸水率等性能进行了测试,并对其微观形貌作了表征。结果表明:在加工过程中,弹性体发生了接枝反应,生成了马来酸酐(MAH)-g-弹性体反应型增容剂,该增容剂进一步与尼龙66和玻璃纤维发生化学反应,强化了三元复合材料的界面作用。当弹性体乙烯-1-辛烯共聚物(POE)、三元乙丙橡胶(EPDM)或乙烯-乙酸乙烯酯(EVA)的加入量为15份(质量)时,相应三元复合材料的缺口冲击强度分别为尼龙66的5.8,6.7,4.7倍;拉伸强度分别为109.32,99.30,85.46 MPa。

| Abstract: | Nylon 66/elastomer/glassfiber ternary composite was prepared by reactive extrusion technology.The properties of the compound such as microstructure,impact strength,melt flow rate and water absorption were measured,and the micromorphology of it was also observed.The results showed that during the extrusion graft reaction between elastomer and maleic anhydride (MAH) took place.Then the graft product reacted with nylon 66 or fiber glass strengthening the interfacial bond of the ternary composite.When the mass fraction of elastomer such as ethylene-1-octene copolymer(POE),ethylene-propylene-diene copolymer(EPDM) or ethylene-vinyl acetate(EVA) was 15%,the notched impact strength of composite were 5.8,6.7,4.7 times of that of nylon 66 correspondingly,and the tensile strength of compounds were 109.32,99.30,85.46MPa respectively. |
