Abstract

The invention relates to a preparation method of kaolin organic and intercalation composite, in particular to a preparation method for octadecyl amine (ODA) / kaolin intercalation composite, which is characterized in that: the preparation method comprises the steps that: 1) producing hydrazine / kaolin intercalation composite: coal-series kaolin is selected as raw material, hydrazine hydrate solution with 17 mol / L of molar concentration is added, and the mass of the added solution is 30 to 60 percent of that of coal-series kaolin; 2) preparing ammonium acetate / kaolin intercalation composite: ammonium acetate saturated solution is added, the mass of which is 30 to 100 percent of the hydrazine / kaolin intercalation composite; 3) making octadecyl amine (ODA) / kaolin intercalation composite: octadecyl amine (ODA), the mass of which is 5 to 40 percent of the ammonium acetate / kaolin intercalation composite, is added into an oil bath pot and stirred for 1 to 2 hours at the temperature of 60 -80 DEG C, and then is sent into a baking oven to keep constant temperature for 12 to 24 hours, the temperature within the oven is 50 to 75 DEG C, a cooled composite is obtained after being taken out and cooled; mixed solution of ethanol having the volume ratio of 1:1 of the cooled composite and water is washed and filtrated, and then the obtained material is dried in a baking oven for 12 to 24 hours, and the temperature in the oven is 50 to 65 DEG C; the octadecyl amine (ODA) / kaolin intercalation composite is finally made. The method of the invention has simple technique; raw material is easily obtained; spacing of layers of kaolin structure lamellar is effectively enlarged with stable performance.

Description

technical field

[0001] The invention belongs to the field of deep processing and modification of non-metallic mineral materials. Specifically, it relates to a method for preparing a kaolin organic intercalation compound. Background technique

[0002] Kaolin is a common clay mineral that is widely used in papermaking, coatings, plastics, rubber, ceramics, refractories, glass fibers, building materials, chemicals, automobiles and aerospace. Kaolin in nature is mainly composed of kaolinite, which is also commonly known as kaolinite.

[0003] Kaolin in nature generally needs to be processed and modified before it can be used. Using the layered structure of kaolin to carry out organic intercalation is an important method for modification. The reactions between clay minerals and organic compounds can occur through mechanisms such as adsorption, intercalation, and ion exchange. Intercalation refers to inserting a layer of other molecules or compound guests into the inorganic ho...
