蒙脱土有机插层改性及其插层性能

摘要

以十六烷基溴化铵（CTAB）和十八烷基胺（ODA）为有机改性剂制备了有机蒙脱土,研究了反应时间、反应温度、改性剂的用量对蒙托土插层性能的影响,通过傅里叶变换红外光谱图仪（FTIR）、X-射线衍射仪（XRD）和综合热分析（TG-DTA）对其结构和形貌进行表征。结果表明,以十六烷基三甲基溴化铵为改性剂,反应温度为80℃,反应时间为60 min,改性剂用量为115 mmol/100 gMMT制备的有机蒙脱土层间距最大d001=2.206 nm。%In the study organic montmorillonite clay were respectively prepared by using CTAB and ODA.The effects on montmorillonite intercalated of the reaction temperature,time and the dosage of modified agents were researched.The structure and morphology characterized by FTIR,XRD and TG.The results indicated that the CTAB as modifier,the reaction temperature was 80 ℃,the reaction time was 30 minutes,the amount of modifier was 115 mmol/100 g MMT,the interlamellar spacing of organic montmorillonite is the most biggest,his spacing d001=2.206 nm.
