The invention discloses an antibacterial anticorrosive led heat-dissipation coating. The coating comprises, by weight, 1-2 parts of N-salicylanilide, 2-3 parts of 8-copper quinolinate, 310-400 parts of high-density polyethylene, 100-130 parts of sodium hydroxide, 400-420 parts of biaphenol A, 160-180 parts of epoxy chloropropane, 10-12 parts of silicon nitride, 2-3 parts of acrylamide, 1-1.6 parts of ammonium chloride, 0.05-0.1 part of N,N-methylene-bisacrylamide, 3-4 parts of ammonium persulfate, 0.01-0.02 part of TritonX114, 1.8-2 parts of ammonium hydroxide, 10-20 parts of diethylenetriamine, 30-42 parts of carbon nano-tubes, 4-5 parts of 2,2-dimethylol propionic acid, 2-3 parts of calcium propionate, 5-7 parts of chlorinated paraffin, 20-30 parts of isopropanol and 1-3 parts of aluminum hydroxide. The N-salicylanilide, the 8-copper quinolinate, the calcium propionate and others are blended, in this way, the antibacterial anticorrosive performance of the coating can be effectively improved, working requirements of different environments are met, weather resistance is good, and the service life is long.
