The invention discloses high-temperature-resistant heat-dissipating graphene-carbon nanotube coating. The high-temperature-resistant heat-dissipating graphene-carbon nanotube coating comprises the following components in parts by weight: 30-40 parts of a graphene-carbon nanotube composite slurry, 28-45 parts of waterborne fluorocarbon resin or a fluorocarbon resin emulsion, 15-30 parts of water, 0.1-0.3 part of a defoaming agent, 0.1-0.3 part of a leveling agent, 0.1-0.3 part of a thickening agent and 2-5 parts of dipropylene glycol methyl ether. A preparation method of the high-temperature-resistant heat-dissipating graphene-carbon nanotube coating comprises the following steps: grinding the graphene-carbon nanotube composite slurry till the fineness is lower than or equal to 30 microns; then performing magnetic field induction; then sequentially adding water, the defoaming agent, the waterborne fluorocarbon resin or fluorocarbon resin emulsion, the leveling agent, the thickening agent and the dipropylene glycol methyl ether, and stirring at a low speed. By improving the orientation of the tube diameter of carbon nanotubes and then by doping a proper amount of graphene through chemical means, the heat conductivity and the heat emission of the carbon nanotubes and the graphene are further improved, so that the heat-dissipating effect is more ideal; in addition, by replacing a film-forming base material with the waterborne fluorocarbon resin or fluorocarbon resin emulsion with better weather resistance and high temperature resistance, the application field of the heat-dissipating coating is widened.
