Grounding grid anti-corrosion composite coating and anti-corrosion method

The invention relates to the technical field of corrosion prevention of conductive coatings, in particular to a grounding grid anti-corrosion composite coating and an anti-corrosion method. The composite coating is prepared from the following raw materials in percentage by mass: 14.5 to 82.5 percent of aluminum, 14.5 to 82.5 percent of zinc and 1 to 3 percent of rare earth oxide. The anti-corrosion composite coating for the grounding grid is prepared from the aluminum oxide, the zinc oxide and the rare earth oxide, all the components cooperate with one another to achieve a very good anti-corrosion effect, further, the dosage of the components is limited within a reasonable range value, all the components generate a better synergistic interaction effect, the better anti-corrosion effect is achieved, and the service life of the grounding grid is prolonged. When the composite coating is applied to the grounding grid, a good anti-corrosion protection effect can be achieved, and the protection period is long. 本发明涉
