Abstract

The invention relates to a method for stripping a laminated inorganic material, which comprises the following steps of: firstly preparing a laminated inorganic material organic intercalation compound, then decomposing the organic substance at the interlayer of the solid of the laminated inorganic material organic intercalation compound or the laminated inorganic material organic intercalation compound added into a proper solution within short time under the condition of ultrasonic waves or microwaves, escaping from the interlayer of the laminated inorganic material so as to rapidly strip the laminated inorganic material, and finally separating, washing, drying and grinding to obtain a product. By using the method, not only the laminated inorganic material can be stripped within short time, but also the good crystal structure of the laminated inorganic material can be kept, so that the traditional application of the laminated inorganic material is qualitatively improved, and the value is doubled and redoubled.

Description

Technical field:

[0001] The invention relates to a method for peeling off layered inorganic materials, which belongs to the field of preparation of inorganic ultrafine sheet materials. Background technique:

[0002] Layered inorganic materials (kaolin, montmorillonite and anionic clay, etc.) are very important non-metallic mineral materials. Among them, kaolin is mainly used in industries such as papermaking, rubber, ceramics, pigments, cement, building materials, and refractories; montmorillonite is a natural nano-powder with high colloidal properties, plasticity, and cohesive force. Its water absorption is very strong, and it expands with water, and its volume can increase several times to ten times. It is the main component of bentonite. It can be used as drilling mud, binder for foundry sand and iron ore pellets, filler for papermaking, rubber, cosmetics, raw material for absorbents, petroleum decolorization and cracking catalysts in textile and petroleum industries; an...
