摘　　要：以有机改性凹凸棒粘土为填料,采用原位聚合法制备了聚甲基丙烯酸甲酯(PMMA)/凹凸棒粘土(ATP)复合材料,通过红外光谱(FTIR)、扫描电镜(SEM)、热重(TG)、力学性能测试等方法对复合材料进行分析和表征。结果表明,改性凹凸棒粘土与PMMA的相容性良好,在PMMA中分散均匀。而其独特的一维纤维棒状结构也可以对PMMA在一定程度上起到补强、增韧作用,当凹凸棒粘土的加入量在1.5%时,其综合力学性能较佳。With organic modified attapulgite clay as filler, poly （ methyl methacrylate） （ PMMA ）/attapulg- ite composite material was prepared by in-situ polymerization. Infrared spectroscopy （FTIR） ,scanning e- lectron microscopy （SEM）, thermo-gravimetry （TG） and other methods were used to characterize the composite material and the mechanical properties of composite material was investigated. The results indi- cated that organic modified attapulgite clay has good compatibility with PMMA and the modified attapulg- ite clay is more evenly dispersed in PMMA. Its one-dimensional fiber structure has reinforcement, toughe- ning effect on PMMA, when the added amount of attapulgite clay at I. 5% ,the better comprehensive me- chanical properties are obtained.
