摘　　要：采用烯丙基三苯基氯化磷对蒙脱土(MMT)进行有机化处理,并采用熔融插层法制备了聚氨酯丙烯酸酯(PUA)/MMT纳米复合材料,探讨了改性MMT用量对PUA/MMT纳米复合材料性能的影响。结果表明,改性MMT的加入可提高复合材料的耐热性与断裂伸长率,当改性MMT的质量分数为3%时复合材料的综合性能最佳,其起始分解温度和断裂伸长率分别达到了321.8℃和96.03%。The montmorillontie （MMT） was organically modified by allyhriphenylphosphonium chloride, and the polyure- thane acrylate （PUA）/MMT nanocomposite was prepared by intercalation polymerization. The influence of MMT content on the proper- ties of nanocomposite was studied. The results showed that the thermal performance and the enlongation at break of the nanoeomposite were improved by adding MMT. When the mass content of MMT was about 3%, the integrated property of the composite was the best. The initial degradation temperature and the enlongation at break of the nanocomposite reached 321.8℃ and 96.03%.
