摘　　要：用烷基胺盐对钠基蒙脱土(MMT)进行有机处理,采用插层聚合法制备了聚甲基丙烯酸甲酯(PMMA)/MMT及聚(甲基丙烯酸甲酯/丙烯酸丁酯)[P(MMA/BA)]/MMT纳米复合材料,探讨了MMT含量、MMA/BA配比对复合材料性能的影响。结果表明,MMT可提高复合材料的冲击强度和耐热性,MMT含量为2%时复合材料的综合性能最佳,BA可明显提高复合材料的冲击强度,MMA/BA配比为10/1时复合材料的综合性能较好。The Na type montmorillontie(MMT) was organically modified by alkylam monium, PMMA/MMT and P(MMA/BA)/MMT nanocomposite was prepared by intercalation polymerization. The influence of MMT content and the compounding ratio of MMA/BA on the properties of nanocomposite was studied.The results showed that the impact strength and thermal performance of the nanocomposite were improved by adding MMT. When the mass content of MMT was about 2%, the integrated property of the composite was the best. The impact strength of the composite was improved markedly by adding BA. The integrated property was good when the mass ratio of MMA/BA was 10/1.
