摘要:

通过原位聚合法制备了本质阻燃聚苯乙烯[P(St-co-AEPPA)]/有机改性蒙脱土(OMMT)纳米复合物[P(St-co-AEPPA)/OMMT], 并用普通聚苯乙烯/有机改性蒙脱土(PS/OMMT)复合物作为对比实验, 研究了含磷、氮单体丙烯酸羟乙基-苯氧基-二乙基磷酰胺(AEPPA)和OMMT等添加物对本质阻燃聚苯乙烯性能的影响.用X射线衍射仪(XRD)和透射电子显微镜(TEM)分析了复合材料的结构与形貌, 并对OMMT在基体中的分散机理进行了讨论.用差示扫描量热仪(DSC)、热重分析(TGA)和微型量热仪(MCC)研究了材料的热性能和燃烧性能.结果表明, AEPPA和OMMT能够显著提高基体的热稳定性和阻燃性.

Abstract:

Inherent flame retardant styrenic copolymer/organic modified montmorillonite(OMMT) nanocomposites[P(St-co-AEPPA)/OMMT] were prepared by in situ bulk copolymerization. Ordinary polystyrene/organic modified montmorillonite nanocomposites(PS/OMMT) were prepared as comparative experiments. Effect of phosphorus-nitrogen containing monomer(AEPPA) and OMMT on styrenic copolymer was studied. The structure and morphology of nanocomposites were characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM), and the dispersion mechanism of OMMT in matrix was discussed. Differential scanning calorimetry(DSC), thermogravimetric analysis(TGA) and microscale combustion calorimeter(MCC) were used to research the thermal properties and flammability of composites. The results showed that the incorporation of AEPPA monomer and OMMT could significantly improve the thermal stability and flame retardancy of matrix.
