synthesis of organoclay

synthesis of organoclay | 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.

synthesis of organoclay

Synthesis of organobentonite is achieved primarily by reacting bentonite (which may be calcium-based bentonite or sodium-based bentonite) with an organic modifier, such as a surfactant.

Organic bentonite synthesis methods include wet and dry synthesis, as well as pregelation and assisted synthesis. Dry synthesis is a relatively simple method of organic bentonite preparation, including raw material preparation, mixing and heating and drying and crushing.

Wet synthesis is a common method of organic bentonite preparation, mainly including crushing and dispersion, purification and modification, organic cover and filtration, drying and crushing.

We mentioned the crushing and dispersion is the bentonite raw materials are crushed and dispersed in water to make a slurry.

And purification and reforming is the bentonite slurry purification process, and may be modified by adding modifier sodium salt, from calcium-based bentonite into sodium-based bentonite.

In the purified and reformed bentonite slurry by adding organic modifiers (such as long carbon chain quaternary ammonium salts), through the ion exchange reaction, so that the cations of the organic modifiers to replace the cations between the layers of bentonite, thereby expanding the spacing between the layers and the formation of hydrophobic organic bentonite, which is the organic cover.

The whole process of filtration, drying and crushing is filtered to remove excess water, and then drying process, and finally the dried product is crushed and sieved to obtain organic bentonite products. These steps whether wet or dry processing means are similar.

At present, the market, the synthesis of organoclay a variety of methods, each method has its unique advantages and scope of application. In practice, according to the specific needs and conditions to choose the appropriate synthesis method.

The main use of organic bentonite is in the paint industry has an important application value, but also widely used in paint and ink, aviation, metallurgy, chemical fiber, petroleum and other industrial fields.

And calcium bentonite: mainly used for regulating in drilling mud, fire-fighting additives, textile industry, water-based waterproof materials and other fields also have important applications.

Synthesis of organoclay has a good gel ability, especially in organic solvents, oils, liquid resins can form a gel, to achieve good thickening, thixotropy, suspension stability, high temperature stability, lubricity, film-forming properties, water resistance and chemical stability.

We suggest that you need to choose the right type of bentonite when choosing the use of bentonite, according to the specific application scenarios and needs to choose the right type of bentonite.
