摘　　要：以福建省武平县蒙脱土作原料,经过提纯和钠化后用十八烷基三甲基溴化铵(TMSAB,Trimethyl stearyl ammonium Bromide)作有机改性剂对蒙脱土进行有机化改性处理,得到有机蒙脱土(TMSAB蒙脱土)。以自制界面改性剂PP-g-MMA为增容剂,改变有机蒙脱土含量,经挤出造粒、注塑成型,制成PP/PP-g-MMA/OMMT复合材料的标准试样。通过测试复合材料的力学性能,并用XRD、DSC、DMA、TG进行表征,当有机蒙脱土含量低于2%时,在复合材料的抗拉强度和冲击强度不下降的情况下,拉伸模量得到较大的提高,达33.3%。The organic montmorillonite was prepared by the Wuping bentonite purified and modified by the octadecyl Trimethyl ammonium Bromide （TMSAB, Trimethyl stearyl ammonium Bromide） in this paper.Then the nanocomposite materials of PP/PP-g-MMA/MMT were prepared by extruding and injecting with the interfacial modifiers preprared by Our laboratory group. It is shown that the elasticity modulus of the composite materials with organic montmorillonite less than 2 % are improved to 33.3 % without the tensile strength and impact strength of the composite materials degradation,by testing the mechanical properties of the composit materials and characterized with the XRD, DSC, DMA and TG.
