The present invention relates to a preparation method and application of an anode used in the passivation process of tinplate, belonging to the field of electrochemistry. A preparation method for an anode used in the passivation process of tinplate, using titanium plate as the substrate. Firstly, an intermediate layer of brush coating solution is brushed on the surface of the titanium plate. After drying, the anode is subjected to constant temperature thermal oxidation at 450-500 ℃ for 10-15 minutes, repeated 10 times, and the final thermal oxidation time is 1 hour; Put the processed titanium plate into the electroplating solution for electroplating, and obtain the passivation anode material. The present invention develops a passivation anode that can enhance the surface adhesion of tinplated plates. The surface adhesion of the tinplated plate produced using this anode is good, and the Cr(OH)₃ content in the passivation film is relatively low. The passivation anode produced by the present invention has the characteristics of hardness and density, being able to be used at high current densities, and high current efficiency.
