Abstract

The invention discloses a preparation method of natural montmorillonite mineral inorganic gel. The preparation method comprises the following steps: S101: material preparation: taking a natural montmorillonite raw material, water, hydrogen ion exchange resin, sodium chloride crystal and electrolyte for later use; S102, purification: crushing the natural montmorillonite raw material subjected to winnowing and impurity removal by using a crusher, then feeding the crushed raw material into a pulping tank for pulping and dilution by using wet purification, and feeding the raw material into a filter press for dehydration after sediment impurity sedimentation so as to obtain a montmorillonite semi-finished product; S103, adding water into the montmorillonite semi-finished product for pulping; S104, adding hydrogen ion exchange resin into the montmorillonite slurry; S105, adding sodium chloride crystals into the montmorillonite slurry; S106, introducing the slurry obtained by the reaction into ultrafine stripping equipment for ultrafine stripping; and S107, adding electrolyte into the slurry subjected to superfine stripping, and uniformly stirring to obtain the montmorillonite inorganic gel. The water dispersibility, the suspension stability and the thickening property of montmorillonite are effectively improved, the cost is low, and the preparation method is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of preparation of montmorillonite inorganic gel, and in particular relates to a preparation method of natural montmorillonite mineral inorganic gel. Background technique [0002] Montmorillonite is a layered mineral composed of extremely fine particles of hydrous aluminosilicate, also known as jiaolingite and microcrystalline kaolinite. It is the main component of bentonite formed by the alteration of igneous rocks such as volcanic condensation rocks in an alkaline environment. It is composed of two layers of silicon-oxygen tetrahedral sheets and a layer of aluminum-oxygen octahedral sheets sandwiched between them. It can be observed under a scanning electron microscope that the thickness of the sheet is only about tens of nanometers. It is a natural nano-mineral Material. The montmorillonite inorganic gel is a high-purity, high-white, ultra-dispersible, high-density natural montmorillonite inorganic gel p...
