摘　　要：选用有机插层剂对蒙脱土(MMT)进行有机化处理后,使用熔融插层法制备了无卤阻燃尼龙66/有机蒙脱土(OMMT)纳米复合材料,测试了其力学性能及阻燃性能。结果表明,有机蒙脱土和少量纳米SiO2的加入能够提高材料的力学性能,当SiO2加入量为2%、蒙脱土含量为3%时,材料的冲击性能相对提高了19%,拉伸与弯曲性能也有所提高;当OMMT∶SiO2为3∶2,APP∶MA为5∶4,ZnO∶APP比值为1·5∶10时,材料的极限氧指数较纯聚合物提高了33·3%。We using organic layer inserted agents modified montmorillonite （OMMT）. PA66/OMMT nanocomposires combined with Halogen-free fire retardants have been prepared by melt intercalation technique used to explore the mechanical properties and flammability. The results showed that the notched izod impact strength of the composite was 19% higher than that of PA66 matrix when the content of the nano-meter silica was 2% and OMMT content 3%, the tensile strength and flexural strength of the composite was higher also. When the ratio of OMMT/SiO2 was 3 ： 2, APP/MA was 5 ： 4, ZnO/APP was 1.5 ： 10,comparing pure polymer its oxygen index of the materials improved 33.3%.
