NOVELTY - A heat-dissipating coating comprises 35-55 %mass water-soluble resin, 5-15 %mass graphene oxide, 2-4 %mass nano-boron nitride, 1-3 %mass carbon nanotubes, 3-7 %mass filler, 0.6-2.2 %mass graphene dispersant, 0.5-1.5 %mass aqueous leveling agent, 0.6-1.2 %mass water-based defoamer, and remaining water. USE - Heat-dissipating coating is used for coating electronic appliance. ADVANTAGE - The coating is economical by containing water as solvent, and environmentally-friendly, and has rapid curing property even without adding curing agent, and excellent thermal conductivity and heat dissipating property due to the presence of graphene, weather resistance, adhesiveness, strength, high-temperature resistance, and electrical insulation performance, and can be prepared with reduced energy consumption.
