中文摘要：

采用氧化-离子交换法将黑云母制成蛭石型水钡云母,以十八烷基三甲基氯化铵作为柱撑剂对水钡云母插层改性.控制柱撑剂浓度不变,研究反应温度和反应时间对柱撑效果的影响.用X-射线衍射图谱和傅里叶红外检测对样品进行物相和微观结构表征.结果表明,当柱撑剂浓度不变时,反应时间和反应温度均不会影响改性剂在云母中的排列方式.反应温度影响插层速度,当反应温度为80℃时,插层速度快且低耗能;反应时间影响插层量,反应时间越长插层量越多,最终达到最大值.

英文摘要：

Vermiculite-type barium-mica was prepared by oxidation and ion-exchange methods using biotite asraw material, and then it was modified by using stearyl trimethyl ammoium chloride as pillared-reagent. Theeffects of reaction temperature and time on modification were studied at kepting the concentration of pillared-reagent constant. The phase and microscopic structure of modified biotite were characterized by X-ray diffractionspectrometry and Infrared spectroscopy. The results show that both the reaction temperature and reaction timehave a little impact on the arrangement of pillared-reagent in biotite when the concentration of pillared-reagentremains unchanged. The reaction temperature mainly influences the intercalated speed, and the intercalatedspeed is high with lower energy comsumption when the temperature is 80 ℃. The reaction time significantlyinfluences the amount of inserted pillared-reagent, the longer the reaction time, the higher the amount of insertedpillared-reagent, and finally reaching the maximum values.
