organoclay bentonite

organoclay bentonite | Organophilic Clay CP-2 also named amine treated Bentonite.

In diesel oil based fluids,organophilic clay viscosifier CP-2 are used to increase carrying capacity and suspension properties, providing support for weight materials and improved cutting removal. Organophilic bentonite also aids in filter-cake formation and filtration control.

organoclay bentonite

The advantages of quaternary ammonium modified bentonite include improved adsorption properties, improved dispersion properties, and improved thixotropy and rheology.

Currently, the main preparation methods include dry and wet methods.

In terms of application areas, organoclay bentonite is used in paints and coatings, inks, greases, cosmetics, oilfield drilling fluids, sealants, and so on. Bentonite has a layered structure with exchangeable cations between the layers.

The modification of organoclay bentonite can be realized through the exchange of quaternary ammonium salt cations with the cations between the layers of bentonite.

Bentonite containing 20% to 30% water and organic modifiers (quaternary ammonium salt) directly mixed, heated, mixed and extruded to produce organic bentonite directly. Or further drying, crushing into powdered products.

Dry preparation process is simple, but usually need to be carried out under high pressure or surfactant melting temperature, energy consumption, and the homogeneity and stability of the resulting product may be affected. This is the dry preparation of organic bentonite.

Bentonite minerals are crushed and dispersed in water to make a slurry, and then organic modifiers (quaternary ammonium salts) are added, and the reaction is carried out under sufficiently stirred conditions to achieve the purpose of organicization.

Wet synthesis of equipment and operation requirements are relatively low, and the preparation process is easier to control, so it is currently the preparation of organoclay bentonite commonly used methods, which is the wet preparation of bentonite.

The amount of quaternary ammonium modified bentonite has an important relationship with the specific application area, the desired effect, and the quality of the modified bentonite. Therefore, the specific dosage standard can be obtained through experiments.

In cosmetics, detergents and other daily chemical field, quaternary ammonium salt modified bentonite as a rheological additives or thickeners, its dosage will usually be based on the product formulation and performance requirements to determine the recommended amount of 1% to 3%, can be adjusted according to actual needs.

In the field of paints and coatings, quaternary ammonium salt modified bentonite as a paint improver, its dosage will also be determined according to the type of paint and coating, the system and the requirements to be achieved and other factors.

Generally speaking, it is recommended to conduct a test before use to determine the optimal dosage, and we generally recommend a dosage of 2%-5%.
The dosage of quaternary ammonium modified bentonite depends not only on its own quality, but is also influenced by factors such as the rectification chemical formulation.

Different types of formulations and modification processes may result in different properties of modified bentonite, thus affecting its dosage.
