description The invention relates to a method for preparing a kaolinite intercalation complex. The method for preparing the stearic acid(sodium stearate)/kaolinite intercalation complex comprises the following steps: 1, comminuting raw kaolin ore to 200-325 meshes, and purifying to remove impurities; 2, mixing kaolin with an intercalator solution according to a mass ratio of kaolin/intercalator of 1:2, and carrying out liquid direct intercalation at normal temperature; 3, grinding a kaolin intercalation complex obtained after direct intercalation and stearic acid(sodium stearate) for uniform mixing, mixing the obtained mixture with an aqueous solution of liquid alcohol according to a mass ratio of 1:10-1:30, placing the obtained solution in a laboratory microwave oven, reacting for 3-48h, repeatedly washing the obtained product by using the aqueous solution of alcohol several times to remove stearic acid(sodium stearate) molecules adhered to the surface in order to prepare the stearic acid(sodium stearate) intercalation compound. The interlamellar spacing of the stearic acid/kaolinite intercalation complex is greatly improved to about 4.2nm, the interlamellar spacing of the sodium stearate/kaolinite intercalation complex is improved to 5.17nm, and a transmission electron microscopy analysis result shows that parts of kaolinite lamellas are curled.
