Abstract

The invention discloses a nanosheet layered carbon black emulsion and its preparation method and application. The powdery carbon black is ground in the presence of abrasives and water, and then dried to obtain block carbon black, block carbon black and dispersant , mixed with water and then ground to obtain a nano-sheet carbon black emulsion, so as to obtain a nano-carbon black emulsion with a carbon black particle size not higher than 100nm; It has better application performance, and avoids dust pollution in the preparation process; the processing equipment of the present invention is conventional equipment, which is a green manufacturing technology.

Description

Technical field [0001] The present invention relates to a preparation technique of a carbon-based material, and more particularly to a nano sheet-like carbon black emulsion prepared to solve the dust pollution of existing powdered carbon black and significantly improve the performance of carbon black materials. Background technique [0002] Carbon black particles are a statistical binding of the carbon-level, which is arranged in concentric graphite. Carbon black In the production process, the incomplete cleavage of hydrocarbon substances will still contain a small amount of hydrocarbons in the product, especially polycyclic aromatic substances. These materials are wrapped in the surface of the carbon black particles such that the surface of the carbon black particles exhibits non-polar, and the specific surface area is large, resulting in the presence of carbon black particles, usually in the context, under the action of shear external force, aggregate It can be reissued and can...
