摘　　要：以聚磷酸酯三聚氰胺(MPP)、改性烷基苯酚甲醛树脂(MAR)为阻燃剂,通过二者之间的协同效应改善尼龙6/玻璃纤维(PA6/GF)复合材料的阻燃性能。采用熔融共混法制备了添加不同MPP/MAR用量的PA6/GF复合材料,通过测定极限氧指数(LOI)、垂直燃烧等级、炭层形貌研究了二者的协同阻燃机理,并测试了PA6/GF复合材料的力学性能。结果表明:当MPP/MAR用量比为10/10时,LOI达到最大值29.3%,垂直燃烧等级为V-0级,热释放速率最低,仅为116.3 kW/m2;添加MPP及MAR对于提高PA6/GF复合材料的力学性能具有一定作用。The flame retardancy of nylon 6/glass fiber(PA6/GF)composites was improved by synergistic effect of melamine polyphomarhate(MPP)and modified alkylphenol formaldehyde resin(MAR).PA6/GF composites with different MPP/MAR content were prepared by melt blending method.The flame retardant mechanism of PA6/GF composites was studied by limiting oxygen index(LOI),vertical combustion grade and morphology of carbon layer.The mechanical properties of the material were further tested.The results show that when the ratio of MPP/MAR is 10/10,the LOI reaches 29.3%,the vertical combustion level is V-0,and the heat release rate is the lowest,only 116.3 kW/m^2.The addition of MPP and MAR can improve the mechanical properties of PA6/GF composites.
