NOVELTY - Preparing radiating coating comprises (a) mixing an organic resin and a diluting agent to obtain a mixed solution, mixing carbon nanotube and graphene, ball-milling, adding graphite ball milling to obtain nano carbon powder, (b) mixing a part of the mixed solution with aluminum oxide and ball-milling to obtain a first mixture, mixing another part of the mixture with nano- carbon powder and ball-milling to obtain a second mixture and (c) performing ball milling twice after mixing the first mixture and the second mixture and the time and rotation speed of the second ball milling are both greater than those of the first ball milling to obtain the radiating coating. USE - The method is useful for preparing radiating coating. ADVANTAGE - The method: is easy to operate and can improve the radiating performance of coating containing graphene.
