Abstract

The invention discloses a production method of organobentonite. The method comprises the following steps: step 1, taking 55-65 parts of N,N-dimethyl octadecyl amine in weight and 10-15 parts of absolute alcohol in weight into a reaction vessel, enabling the inner side temperature of the reaction vessel to be 20 DEG C, starting stirring for 1.5 hours, stirring while adding 25-30 parts of liquid chloromethane in weight, and keeping the temperature at 20-60 DEG C for 60 minutes after the stirring is completed to prepare octadecyl ammonium chloride; step 2, taking 50 parts of bentonite, adding water to dilute the bentonite to be a suspending liquid, starting stirring for 40 minutes, stirring while adding 2 parts of prepared octadecyl ammonium chloride, and keeping the temperature at 20-60 DEG C for 60 minutes after the stirring is completed to produce the organobentonite. According to the organobentonite produced by the method, the whiteness is increased, the viscosity is enhanced, and the combustion amount is improved.

Description

technical field [0001] The invention relates to the field of light industry and chemical industry, in particular to a method for preparing organic bentonite. Background technique [0002] Organobentonite is an inorganic mineral / organic ammonium compound, using bentonite as raw material, using the lamellar structure of montmorillonite in bentonite and its ability to swell and disperse into colloidal clay particles in water or organic solvents, through ion exchange technology inserts organic mulch. Organobentonite can form gels in various organic solvents, oils, and liquid resins, and has good thickening properties, thixotropy, suspension stability, high temperature stability, lubricity, film-forming properties, water resistance and chemical stability. , has important application value in the paint industry, and is also widely used in paint ink, aviation, metallurgy, chemical fiber, petroleum and other industries. However, the organic bentonite produced by the existing metho...
