This invention relates to a heat transfer protective film for metal corrosion protection, comprising a heat-resistant layer coated on one side of a base film, and an adsorption layer, a strong anode layer, and a weak anode layer sequentially coated on the other side of the base film. Sacrificial anode cathodic protection is an effective method for metal corrosion protection, while heat transfer technology transfers graphic coded information onto a substrate using a heat transfer printer or similar method. Because the coating can be prepared in advance, it can form heat transfer protective films with multiple functions. By preparing an anode coating containing an active metal, coating it as a heat transfer protective film, and then transferring it onto a metal substrate, the sacrificial anode material protects the cathode metal while imparting graphic coded information to the metal substrate. This represents a new metal corrosion protection mode that adapts to the development of the information age.
