Abstract

The invention discloses a nano lamellar carbon black emulsion as well as a preparation method and application thereof. The preparation method comprises the steps that powdery carbon black is ground in the presence of a grinding agent and water and then dried, blocky carbon black is obtained, the blocky carbon black is mixed with a dispersing agent and water and then ground, and then the nano carbon black emulsion with the carbon black particle size not larger than 100 nm is prepared. The nano carbon black is converted into a lamellar structure from a spherical structure and has more excellent application performance than one-time grinding or cleavage, and dust pollution is avoided in the preparation process; and the processing equipment is conventional equipment, and a green manufacturing technology is provided.

Description

technical field [0001] The invention relates to a preparation technology of a carbon-based material, in particular to the preparation of a nanosheet layered carbon black emulsion, so as to solve the dust pollution of the existing powdery carbon black and obviously improve the performance of the carbon black material. Background technique [0002] Carbon black particles are a statistical combination of carbon layers arranged in concentric graphite layers. In the production process of carbon black, due to the incomplete cracking of hydrocarbons, the product still contains a small amount of hydrocarbons, especially polycyclic aromatic hydrocarbons. These substances are wrapped on the surface of carbon black particles, so that the surface of carbon black particles is non-polar and has a large specific surface area, which makes carbon black particles very easy to aggregate, usually in the form of aggregates. Can be re-dispersed, and can be re-gathered. The surface coating of ca...
