Abstract

The invention provides a nano-carbon material. The nano-carbon material comprises crystalline flake graphite serving as a raw material. The preparation method comprises the following steps: S1, carrying out grinding operation on the raw material crystalline flake graphite through grinding equipment, wherein the rotating speed of the grinding equipment is set to range from 3000 r / min to 4000 r / min,and the temperature in the grinding equipment is set to range from 25 DEG C to 30 DEG C, and obtaining particles uniform in size; and S2, soaking the particles in the step S1 in a mixed solution of aromatic hydrocarbon, alcohol and ether for 30-60 minutes, and carrying out over-temperature drying on the soaked particles in drying equipment at 800-900 DEG C to obtain soaked particles. The preparednano carbon material is uniform in size and dispersion; and different from common nano carbon materials, the material has a certain lamellar structure while having a part of graphene structure, but the lamellar structure has weak binding, so that the material has lager apparent density than that of the common nano carbon materials, and is convenient to store and transport and easy for polymer compounding.
