摘要
将湖南修梅膨润土钠化,对该钠化膨润土的阳离子交换容量和吸蓝量进行了测定,确定了修梅膨润土中蒙脱石的百分含量;将钠化膨润土用十六烷基三甲基溴化铵作覆盖剂对其进行有机改性,探讨了反应温度、反应时间等因素对改性反应影响,确定了较佳的工艺条件;粘度测试、红外及热重—差热分析表明,湖南修梅膨润土的有机改性是有效的.
The bentonite from Xiu-Mei has been modified by hexadecyl trimethyl ammonium bromide after it was treated by sodium carbonate.The cation-exchange capacity and the amount of methylene blue absorption of the bentonite treated by sodium carbonate were determined.Some influence factors on modified reactions such as reaction temperature and reaction time and so on were discussed. The quality of organobentonite was investigated by means of IR and TG-DTA and determination of viscosity. The results show that the bentonite from Xiu-Mei can be made to organo-bentonite.
