采用双螺杆挤出加工工艺，通过添加不同组分制得超韧无卤阻燃尼龙(PA)6材料，比较了不同黏度PA6、增韧剂、阻燃剂及加工工艺对材料性能的影响。结果表明，中黏搭配低黏PA6材料可获得最佳的冲击性能和加工性能；在添加15份马来酸酐接枝乙烯–辛烯共聚物增韧剂时增韧效果最好；小粒径、高含量(红磷)红磷母粒的阻燃效果较好且对体系的力学性能影响较小；Mg(OH)2具有很好的协效阻燃和消烟作用，在添加量为3份时效果最佳；适当的螺杆组合可提高体系的阻燃稳定性。

Super toughened halogen-free flame retardant nylon(PA) 6 flame was prepared by adding different components using twin-screw extrusion process. The effects of different viscosity nylon 6,toughening agents,flame retardants and processing technology on the material properties were studied. The results show that the material can obtain optimum impact resistance and processability by mixxing middle viscosity PA6 with low viscosity PA6;the toughening effect is the best when adding 15 parts POE-g-MAH;red phosphorus masterbatch of small size and high phosphorus content has good flame retardancy and less impact on the mechanical properties of the system;Mg(OH)2 has a good synergistic effect of flame and smoke,and the optimal content is three parts;appropriate screw combination can improve flame stability of the system.
