采用超声波法,以二甲亚砜作为插层中间体,将1,2-丙二醇插入高岭土层间,制得丙二醇插层复合物。通过XRD检测表明,1,2-丙二醇能够插入高岭土层间,随着插层时间延长,硅酸盐片层发生了剥离,形成粒径为纳米级颗粒,并且分散均匀。与传统方法相比,插层时间大大缩短,插层工艺简单、插层效率高,便于进一步实现工业应用。 Using ultrasonic method, with dimethyl sulfoxide as an intercalated intermediate, 1,2-propanediol was inserted into the kaolin layer to prepare a propylene glycol intercalation compound. The results of XRD showed that 1, 2-propanediol could be inserted into the kaolinite layer. With the prolongation of the intercalation time, the silicate layer peeled off to form nano-sized particles with uniform dispersion. Compared with the traditional method, the intercalation time is greatly shortened, the intercalation process is simple, and the intercalation efficiency is high, which is convenient for further industrial application.
