摘要
利用动态硫化法制备尼龙(PA)6/溴化丁基橡胶(BⅡR)合金,通过对其拉伸强度、冲击强度及熔体流动速率(MFR)等性能进行测试,讨论了马来酸酐(MAH)对合金力学性能和流动性能的影响,通过扫描电子显微镜观察合金冲击断面的形貌。结果表明,当MAH的含量为0.5份时,合金的力学性能和流动性能最好,此时的拉伸强度为19.8 MPa,断裂伸长率为15%,缺口冲击强度为26.1 kJ/m2,MFR为0.15 g/(10 min)。该合金可以作为阻气材料的衬里使用。
PA6/BⅡR alloy was prepared by dynamic vulcanizing method.The effects of MAH on mechanical properties and flow properties of PA6/BⅡR alloy were discussed through the tests of tensile strength,impact strength and melt flow rate（MFR）,and the impact fracture surface morphology of the alloy was observed by SEM.The results indicated that the mechanical properties and flow properties of PA6/BⅡR alloy were best when the content of MAH was 0.5 phr,and tensile strength,elongation at break,notched impact strength and MFR of the alloy was 19.8 MPa,15%,26.1 kJ/m2,and 0.15 g/（10 min） respectively.The alloy could be used as the lining of gas-barrier material.
