A kind of preparation method of graphene composite heat-dissipating coating and centrifuge thereof

Abstract

The embodiment of the invention discloses a preparation method of graphene composite heat-dissipating paint and its centrifuge. The graphene injection pipe on the main body of the centrifuge is connected to the inside of the drum through the stock solution separation cylinder, and the stock solution The separation cylinder cooperates with the drum to separate the injected graphene stock solution and the separated graphene supernatant; the outer side of the stock solution separation cylinder is equipped with a plurality of solid slag and graphene supernatant that cooperate with the drum to separate graphene A plurality of centrifuge discs cooperate with the fast equidistant installation to form a plurality of separation chambers for separating the graphene stock solution; by setting a height-limiting groove group outside the stock liquid separation cylinder, the centrifuge Separate the discs, and quickly limit the height of the inserted multiple centrifugal separation discs through multiple disc height-limiting slots with increasing lengths, so that the adjacent spacing of multiple centrifugal separation discs after installation in sequence is the same, no need Manual additional debugging.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of heat-dissipating paint preparation, in particular to a method for preparing a graphene composite heat-dissipating paint and a centrifuge thereof. Background technique [0002] With the development of science and technology, people focus on the development of materials with high thermal conductivity and good heat dissipation effect.
