摘　　要：采用熔融插层法制备了不同有机蒙脱土(OMMT)及无机蒙脱土(MMT)含量的HIPS/OMMT和HIPS/MMT复合材料,并通过锥形量热仪评价了复合材料的阻燃性能;采用数码相机、扫描电镜(SEM)观察了燃烧残余物结构。结果表明,OMMT的加入显著提高了HIPS/OMMT复合材料阻燃性,而MMT的加入,HIPS/MMT复合材料的阻燃性能提高不明显。HIPS/OMMT复合材料燃烧结束形成了皮层-蜂窝层复合的炭渣结构,对其阻燃性有重要的影响。HIPS/OMMT and HIPS/MMT composites with the different organic montmorillonite （OMMT） and inorganic montmorillonite （MMT） content were prepared through the melting intercalated method. The flame retardancy was evaluated by the cone calorimeter. The structure of burnt residues was observed by digital camera and scanning electron microscope （SEM）. The results show that flame retardaney of HIPS/ OMMT composites is significantly improved in comparison with the pure HIPS, while flame retardancy propertiy of HIPS/MMT composites is improved very few. The burnt residue of HIPS/OMMT is composed of skin layer and cellular layer after burning. The structure of char residues has a great effect on the flame retardancy of the composites.
