利用溶液插层方法对蒙脱土进行了有机化插层处理,通过对蒙脱土进行酸化和有机化两步处理,发现酸化处理不仅能有效地扩大蒙脱土的片层间距,还能有效地增强有机蒙脱土在甲苯、二甲苯等有机溶剂里的相容性。利用TGA、XRD、FT-IR等手段对有机化的蒙脱土内部结构进行了表征,并对酸化机理进行了探究。

Montmorillonite(MMT) is treated by the intercalation of organic using the method of solution intercalation.It included acidification and organization treatment.The results showed that the acidification can not only expand the interlayer spacing of MMT,but also effectively improve the compatibility of organic montmorillonite in toluene,xylene and other organic solvents.The microstructure and morphology of organic montmorillonite were investigated by TGA,XRD and FT-IR.Furthermore,the acidification mechanism was also studied.
