摘要
本文用十八烷基胺聚氧乙烯醚双季铵盐和溴化十六烷基吡啶为复合改性剂,改性Ca基膨润土,用X射线衍射分析、红外光谱、热失重分析对改性前后膨润土的结构进行表征,并探讨了在其他条件不变下,改变改性剂的比例对插层效果的影响。
In this paper, the Ca - bentonite was modified by the Composite modifier which was composed of Gemini surfactant and Hexadecylpyridinium bromide. The structure of the modified bentonite before and after was characterized by X - ray diffractometer （XRD）, fourier transform infrared spectrosco - py （FTIR）, and differential thermal analysis and thermogravim etric analysis （DTA - TGA）, and discussed change the proportion of modifier in the other conditions remain unchanged, the effects on the intercalation.
