高阻隔性可吹塑尼龙6复合材料的研究

STUDY ON THE BLOW-MOULDABLE NYLON 6 COMPOSITE WITH HIGH BARRIER

通过(聚烯烃热塑性弹性体/丙烯酸酯类)共聚物(MST)与尼龙6进行反应共混,研究了不同MST含量对复合材料的熔体流动速率、流变性能、吸油率、拉伸强度、断裂伸长率和冲击强度等的影响。研究结果表明,MST含量约为10％时,可以得到综合性能优于尼龙6的可吹塑高阻隔性的材料,该材料可以用作汽车燃油箱、农药瓶、药品瓶等有高阻隔性要求的包装材料的专用料,具有广阔的应用前景。

The nylon 6/MST composites possessing high barrier and being blow-mouldable are studied. The barrier property, mechanical property, melt flow rate ( MFR) , rheological property of the materials are investigated in detail. The barrier property of the container made by the blow molding is excellent.
