Preparation method of graphite electrode beneficial to loss reduction
The invention discloses a preparation method of a graphite electrode beneficial to loss reduction, and relates to the technical field of electrode preparation. The preparation method comprises the following steps of: S1, weighing the following raw materials in parts by weight: 30-32 parts of petroleum coke, 20-25 parts of needle coke, 10-12 parts of modified asphalt, 2-3 parts of graphene, 5-7 parts of polyoxyethylene fatty alcohol ether, 2-4 parts of polymethyl methacrylate, 1-3 parts of calcium oxide, 0.5-0.7 parts of ferric oxide, 20-30 parts of carbon fibers and 5-8 parts of copper powder.The polymethyl methacrylate and the carbon fibers are added into the raw materials, the oxidation resistance of the graphite electrode is improved, and the breakage-proof rate of the graphite electrode in use is increased. An ion adsorption step is added, so that zinc ions are attached to a dendritic structure formed between the graphene fibers in the graphite electrode and other raw materials, the conductive performance of the graphite electrode is effectively improved, and the graphite electrode has stable current conductivity. The strength of the finished graphite electrode is effectivelyimproved by adding polymethyl methacrylate and ferric oxide.
