NOVELTY - Heat dissipation coating comprises 25-35 pts. wt. graphene, 25-35 pts. wt. acrylic resin, 10-15 pts. wt. amino resin, 8-12 pts. wt. polyacrylamide, 8-12 pts. wt. polyvinyl butyral, 5-8 pts. wt. titanium nitride particles, 5-8 pts. wt. heat conductive metal powder, 5-8 pts. wt. carbon fiber powder, 3-6 pts. wt. anti-settling agent, 3-6 pts. wt. activation agent and 3-6 pts. wt. dispersant. USE - The heat dissipation coating is useful for car engine. ADVANTAGE - The coating: can be sprayed on the surface of the car engine; and absorbs and quickly discharges heat. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the heat dissipation coating comprising introducing graphene, acrylic resin and amino resin into a stirrer, mixing and stirring, grinding by a grinding device until the particle diameter is 20-40 mu m to form a first mixture, adding polyacrylamide and polyvinyl butyral to the first mixture, mixing with titanium nitride particles, heat-conductive metal powder, carbon fiber powder, anti-settling agent and dispersant, transferring to a fine grinding device, grinding for the second time, filtering the obtained mixture through a filtration device having an aperture of 8-16 mu m and filtering the large particles in the mixture to obtain coating.
