| 摘 要： | 利用阴离子表面活性剂十二烷基磺酸钠(SDS)改性天然蒙脱土，研究了反应介质的酸碱性对插层效果的影响。X射线粉未衍射（XRD）、红外光谱（FT-IR）、热重分析（TGA）表明SDS已插层到蒙脱土片层间，沉降实验和流变学性质研究表明改性后蒙脱土在有机介质中表现出很好的分散性、溶胀性和高触变性。这种改性效果优于目前常用的十六烷基三甲基溴化铵(CTAB)处理效果。解释了阴离子表面活性剂对蒙脱土的插层机理。

| Abstract: | Na-Montomorillonite(Na-MMT) is modified with anion surfactants sodium laurylsulfonate and the effects of pH value on the intercalation are studied. The results of XRD, FT-IR and TGA indicate that the sodium laurylsulfonate has intercalated into the galleries of MMT. Sedimentation experiment and rheology property show that the MMT modified with sodium laurylsulfonate have better dispersibility, swelling and thixotropic property than the MMT modified with Cetyltrimethylammonium bromide. The intercalation mechanism of anion surfactants is also explained. |
