| 摘 要： | 活性白土是膨润土经硫酸活化处理而得。酸处理条件明显地影响了活性白土的化学组成和结构状态。对其控制并制备化学组成和结构都适宜的活性白土,能与有机胺类化合物和硅烷偶联剂及结晶紫内脂等有机分子作用,发生层间吸附、键合、吸电子等作用。应用这些性质,可将粘土矿物制备成橡胶、环氧树脂补强填料及无碳复写纸显色剂。

| Abstract: | Atlapulgite is obtained by activating betonite with sulfuric acid. The chemical composition and structural form of atlapulgite are evidently affected by the acid treatment conditions in activation. The atlapulgite with proper chemi- cal composition and structure can thus be prepared by controlling acid treatment conditions. It is able to act on the organic molecules, such as organic aminates and silane coupling agent and crystal violet lactone, and brings forth interlami- nal adsorption as well as bonding or electron attraction. All these properties are useful in preparing rubber and epoxy resin strengthening filler and developer of non-carbon copying paper from clay minerals. |
