Method for efficiently-stripped laminar inorganic material

Abstract

The invention relates to a method for efficiently-stripped laminar inorganic material. The method comprises the following steps of: firstly, stripping the laminar inorganic material by using organic micro-molecules; and secondly, completely stripping the stripped laminar inorganic material under the ultrasonic wave condition. The method can ensure that the laminar inorganic material is completely stripped and also can keep a good crystal structure of the laminar inorganic material, so that the use of the laminar inorganic material is radically improved and the value of the laminar inorganic material is multiplied.

Description

Technical field: [0001] The invention relates to a method for efficiently stripping layered inorganic materials, which belongs to the field of preparation of inorganic ultrafine sheet materials. Background technique: [0002] Layered inorganic materials (layered phosphate, kaolin, montmorillonite and anionic clay, etc.) are very important non-metallic mineral materials. Among them, phosphate is mainly used in optics, acoustics, catalysis, molecular recognition, biology and other fields. It is also used to develop materials for adsorbing and sensing gases. Kaolin is mainly used in papermaking, rubber, ceramics, pigments, cement, building materials, refractory materials and other industries; 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 drilli...

Problems solved by technology

[0003] The peeling technology of layered inorganic materials includes mechanical grinding peeling method and chemical peeling method. The disadvantage of relying on mechanical grinding method alone is that excessive grinding will destroy the crystal structure of inorganic materials, resulting in poor product performance. At the same time, the mechanical method consumes more energy. Large; the principle of chemical exfoliation is to use intercalation to expand the interlayer of layered inorganic materials, and the bonding force is greatly weakened. Inorganic materials to achieve the purpose of natural peeling

Xu Jinsuo et al. used the α-ZrP-organic molecule exfoliation method to exfoliate kaolin. Although the exfoliated mother was achieved, the particles were larger and the thickness of the sheet was thicker.
