首先用有机胺通过离子交换反应对层状粘土进行改性，然后将已改性的有机粘土作 为增强介质与通用型不饱和聚酯树脂合成了有机／无机纳米复合材料．利用ＦＴ－ＩＲ、ＸＲＤ、 Ｉｎｓｔｒｏｎ等测试手段对其结构和性能进行了表征，并对影响材料形成的各种因素进行了讨论． 结果表明，经有机胺处理的粘土晶层间距得到了膨胀，而且复合材料的 ＸＲＤ曲线中布拉 格衍射峰消失，说明粘土晶层已基本被聚合物撑开，形成层离型纳米复合材料．复合材料 的力学性能明显增强，仅含有３％（质量分数）处理土的复合材料，其抗冲击强度提高３倍．
Firstly, the layered clay was modified by ion exchange reaction with organic amine, and then the organic / inorganic nanocomposites were synthesized by using the modified organoclay as reinforcing medium and general-purpose unsaturated polyester resin. The structure and properties of the materials were characterized by FT-IR, XRD and Instron. The factors affecting the formation of materials were also discussed. The results show that the distance between the organic amine-treated clay grains expands, and the X-ray diffraction (XRD) of the composites disappears in the Bragg diffraction peaks, indicating that the clay layer has been basically opened by the polymer to form a delaminated nanocomposite. The mechanical properties of the composites were significantly enhanced. The composites containing only 3% (mass fraction) treated soil showed a threefold improvement in impact strength.
