The invention relates to a conductive coating, which is prepared from the following raw materials by weight part: 32-36 of thermoplastic acrylic resin, 3-5 of nano-chitin, 1-2 of polyvinyl alcohol, 2-3 of cellulose nano-fibril, 4-6 of alkyd resin, 8-10 of perchloro-ethylene resin, 3-4 of flake graphite powder, 3-5 of potassium silicate, 0.1-0.2 of texanol ester alcohol, 6-8 of acetone, 1-2 of sodium perfluorooctane sulfonate, 6-8 of ethyl acetate, 0.2-0.3 of alkyl modified organosiloxane, and 4-6 of an adhesion assistant. The coating provided by the invention has the advantages of good gloss and color retention, water and chemical resistance, fast drying, and convenient construction. By adding the nano-chitin and cellulose nano-fibril, the compactness of a film is increased, the water resistance and gas barrier property are good, and the corrosion resistance is improved. By adding the flake graphite powder, the coating can be conductive and antistatic. The coating is easy to coat, has good adhesion to materials, and is not easy to combust.
