Abstract
The invention belongs to the field of dispersing and grinding and particularly provides a dispersing and grinding device for graphene slurry. The dispersing and grinding device comprises a grinding tank, a grinding body and a seal cover, wherein the grinding body is mounted in the grinding tank and can rotate around an axis in the grinding tank under driving of a power mechanism; the grinding body and the grinding tank are both electrically conductive and are connected to different electrodes of a power supply unit respectively; the seal cover is used for sealing the grinding tank and comprises a cover body and a liner plate fixed on the lower surface of the cover body; a liquid inlet and a mounting through hole allowing the grinding body to be connected with the external power mechanism are formed in the upper surface of the cover body; and a plurality of uniformly distributed liquid outlet holes are formed in the liner plate. The dispersing and grinding device can realize efficient dispersion of the graphene slurry and effectively guarantees complete flake structure of graphene.
Description
technical field [0001] The invention belongs to the field of dispersion grinding, in particular to a dispersion grinding device for graphene slurry. Background technique [0002] Graphene is a two-dimensional crystal that is exfoliated from graphite and composed of carbon atoms with only one atomic thickness. Graphene is not only the thinnest material, but also the strongest material, with a breaking strength 200 times higher than the best steel; at the same time, it has good elasticity, and its stretching range can reach 20% of its own size. Due to its own characteristics, graphene has been widely used in many fields such as new energy, new materials, energy chemical industry, electronic information, aerospace and national defense. [0003] Since graphene has a lamellar structure, in order to enable graphene to preserve its better characteristics in the specific application process, it is necessary to maintain the graphene sheet structure during the preparation of graphene...
