Heat-conducting and corrosion resistant paint as well as preparation method and application of paint

The invention belongs to the technical field of metal surface coatings, and provides heat-conducting and corrosion resistant paint. The heat-conducting and corrosion resistant paint comprises the following ingredients in parts by mass (100 parts in total): 15-45 parts of water-based acrylic resin, 0.1-3 parts of a neutralizer, 5-50 parts of carbon material slurry, 3-20 parts of a cross-linking agent, 0.1-2 parts of a catalyst, 0.1-2 parts of an orientation arrangement assistant and the balance of water, wherein the carbon material slurry comprises the following ingredients in parts by mass (100 parts in total): 2-30 parts of a carbon material, 0.2-5 parts of a dispersing agent and the balance of water; the dispersing agent is a crystalline polymer. At the same time, the invention further discloses a preparation method and an application of the heat-conducting and corrosion resistant paint. The heat-conducting and corrosion resistant paint has better corrosion resistance, flexibility and preparation performanc
