采用X射线衍射仪研究了纳米蒙脱土(MMT)和EP/纳米MMT复合材料中纳米MMT的层间距变化。结果表明，纳米MMT与EP/纳米MMT复合材料中纳米MMT的层间距相差不大，说明纳米MMT在EP中只是物理混合，没有发生插层反应。研究了纳米MMT用量对EP/纳米MMT以及EP/聚磷酸铵(APP)/三聚氰胺氰尿酸盐(MCA)复合材料性能的影响。结果表明，纳米MMT的加入不能提高EP/纳米MMT的极限氧指数(LOI)，可以提高EP/纳米MMT复合材料的拉伸强度。纳米MMT与APP和MCA复配作为复合阻燃剂，可以产生明显的阻燃协同效应，当APP和MCA质量比为3∶1，纳米MMT在复合阻燃剂中的质量分数为20%且复合阻燃剂在复合材料中的质量分数为20%时，EP/APP/MCA/纳米MMT复合材料的综合性能最佳，LOI为29.6%，垂直燃烧等级达到UL94 V-0级，拉伸强度和冲击强度分别为45.9 MPa和8.6 kJ/m2。

The distances between layers of nano montmorillonite(MMT) and epoxy resin(EP)/nano MMT composites were studied by X ray diffraction,the results show that nano MMT and nano MMT in EP/nano MMT composites have no difference in the layer distance,which show that nano MMT is just physically mixed with the EP,there are no intercalative polymerization reaction. The influence of nano MMT contents on EP/nano MMT and EP/ammonium polyphosphate(APP)/melamine cyanurate(MCA) composites were also studied,the results show that the addition of nano MMT can not improve the limited oxygen index(LOI) of EP/nano MMT composites,while it can improve the tensile strength of the composites. Nano MMT play prominent synergetic flame retardant effect when used together with flame retardant APP and MCA,EP/APP/MCA/nano MMT composite has a best combination performance when the mass ratio of APP and MCA is 3∶1,the mass fraction of nano MMT in composite flame retardants is 20%and the mass fraction of the composite flame retardants is 20%in the composite,the LOI is 29.6%,the vertical burning rating reach UL94 V-0 level,the tensile and impact strength is 45.9 MPa and 8.6 kJ/m2 respectively.
