Organobentonite is a kind of inorganic mineral/organic ammonium compound. Using bentonite as raw material, the layered structure of montmorillonite in bentonite and its ability to swell and disperse in water or organic solvents to form colloidal clay particles are utilized.

 

Made of organic covering agent by ion exchange technology. Organic bentonite can form gelatin in various organic solvents, Oils and liquid resins, and has good thickening, thixotropy and suspension stability.

 

High temperature stability, lubricity, film forming, water resistance and chemical stability have important application value in coating industry. It also has wide applications in paints, ink, aviation, metallurgy, chemical fiber, petroleum and other industries.

 

English name [1]: Organic Bentonite

 

Chinese Name: organic montmorillonite, organic clay, OMMT

 

Relative density: 1.7~1.8 g/cm3

 

Appearance: white or grayish white powder.

 

Smell: tasteless.

 

Solubility: Soluble in hydrocarbon solvents, with a small amount of polar solvents such as methanol, ethanol, acetone, etc., can make the quaternary ammonium hydrocarbon chain between layers of montmorillonite through hydrogen bond bridging, to obtain effective solvation, thus causing interlayer expansion.

 

Disperse and form thixotropic gel of card roof structure to prevent precipitation of inorganic filler.

 

Toxicity: non-toxic

 

Application: Used as thickener, thixotropic agent and stabilizer of solvent adhesive and sealant, the reference dosage is 5-10 phr. Directly add organic bentonite, stir 1H, add a small amount (2%~3%) polar solvent (methanol or ethanol, etc.).

 

Organic bentonite is a compound of organic quaternary ammonium salt and natural bentonite, which is a fine chemical product developed in recent years. The main characteristics of organo bentonite are swelling, high dispersion and thixotropy in organic media.

 

Organobentonite is generally used as an anti-sedimentation agent and thickener for metal anticorrosive coatings. It has the characteristics of corrosion resistance, wear resistance, salt water corrosion resistance, impact resistance, and not easy to wet.

 

Organic bentonite is the main dyeing aids for synthetic fiber fabrics. In high-speed printing ink, the consistency, viscosity and permeability of the ink can be adjusted according to needs. In drilling, organic bentonite can be used as a latex stabilizer.

 

In the field of high temperature grease, organobentonite is especially used to prepare high temperature grease suitable for high temperature and long time continuous operation.
