Description

technical field

[0001] The invention relates to a method for preparing exfoliated nano-montmorillonite, in particular to a method for preparing nano-montmorillonite by a mechanical method, and provides a method for preparing nano-montmorillonite in the fields of nanocomposite material preparation and fine chemical industry. A new approach that is efficient and easy to industrialize. Background technique

[0002] Montmorillonite, also known as bentonite and microcrystalline kaolin, is named after it was first produced in Montmorillonite, France. It is a silicate clay mineral with layered structure and flaky crystals. Because of its excellent cation exchange, dispersibility, expansion, adsorption, rheology, fire resistance, etc., it is widely used in chemical, pharmaceutical, environmental protection, construction, mining, food and other fields. However, the current application is mostly limited to ordinary fillers. In fact, montmorillonite is still a mineral with a nanostruc...
