【摘要】 以吉林省九台天然钙基膨润土和改性的钠基膨润土为原料 ,用丙烯酰胺和溴代十六烷基三甲基胺进行有机覆盖 ,对制得的有机膨润土进行了X射线衍射 (XRD)分析 ,并结合差热热重 (DTA—TG)分析。结果表明 ,该方法不仅可以制备有机长链季铵盐有机膨润土和小分子有机膨润土 ;而且作为直接原料的天然钙基膨润土也可以制得较好的有机膨润土。更多还原

【Abstract】 In this paper, natrual Ca-bentonite and modified Na-betonite of Jiutai, in Jilin province are covered with acrylamide and cetyltrimethy lemmonium bromide to syntheis organophilic bentonites. The products are analysed by XRD,DTA-TG. The results show that this way can produce organophilic bentonite of long carbon chain quaternary ammonium salt and gain organophilic bentoaite with polymerizable small molecule, and natural Ca-bentonite may also make better organophilic bentonite as direct raw material.更多还原
