摘　　要：根据蒙脱土(MMT)特殊的片层结构,采用熔融插层法制备了HIPS/MMT及HIPS/OMMT复合材料,并用锥形量热仪对材料的燃烧性能进行测试。结果表明,材料中蒙脱土片层的取向影响材料的阻燃性;与竖直取向的HIPS/OMMT复合材料相比,水平取向的HIPS/OMMT复合材料有更低的热释放速率和质量损失速率,具有较高的阻燃性。用扫描电镜表征了不同取向材料燃烧后炭层的形貌,表明形成的炭层也具有横、竖取向。此现象解释了插层复合材料的取向影响材料的阻燃性,为聚合物/层状硅酸盐纳米复合材料阻燃机理的研究提供了依据。HIPS/OMMT composites with different layer orientations of intercalated structure were prepared by the melt intercalation approach. The cone calorimeter was used to assess the flammability of HIPS/MMT as well as HIPS/OMMT composites. The results that the MMT orientation within the HIPS/OMMT demonstrate layer composite affects the flammability of the composites . The HIPS/OMMT composites with horizontal layer orientation gave less heat release rate and less mass loss than the HIPS/ OMMT composites with vertical layer orientation. The detailed structure of layer orientation in the composites has been observeded using the SEM technique, which provides some fundamental explanation for flame retardancy of polymers by intercalation approach.
