Graphite electrode anti-oxidation paint and anti-oxidation coating

The graphite anti-oxidation coating comprises a component A and a component B. The component A comprises a carbon source and a boron source, and the component B comprises an inorganic filler. The component A is used for forming a boron-carbon porous layer, the boron-carbon porous layer comprises a porous carbon skeleton and nano boron particles accommodated in pores of the porous carbon skeleton, the porous carbon skeleton is embedded in the pores of the graphite electrode so as to improve the physical adhesive force, and the porous carbon skeleton can buffer the volume change caused by thermal expansion and cold contraction of the graphite electrode; the nano boron particles are melted in the electrode using process, have fluidity and can cover the surface of the graphite electrode through the capillary action to form a first anti-oxidation layer, and even cracks are generated in the cooling process, the nano boron particles can be self-repaired after being melted; and the component B is used for forming a c
