Abstract

The invention belongs to the technical field of graphite electrodes, and provides a superconducting graphite electrode nano antioxidant, which is prepared from the following components by weight: 80-100 parts of water, 20-40 parts of ceramic powder, 20-25 parts of graphene, 10-25 parts of polyethylene glycol, 6-12 parts of a stabilizer, 5-10 parts of an antioxidant aid and 10-15 parts of polyvinylalcohol. The antioxidant aid comprises calcium boride, vanadium diboride and sodium dihydrogen phosphate in a mass ratio of 2:(0.8-1.2):1. The preparation method includes: grinding the weighed ceramic powder to a particle size of 50-100nm, and adding polyethylene glycol to obtain ceramic powder slurry; adding the ceramic powder slurry and graphene into a solvent to obtain a premixed solution; andsequentially adding the antioxidant aid, the stabilizer and polyvinyl alcohol into the premixed solution, and performing mixing to obtain the superconducting graphite electrode nano antioxidant. By means of the technical scheme, the problem that in the prior art, the oxidation resistance of a graphite electrode nano antioxidant is not good enough is solved.

Description

technical field [0001] The invention belongs to the technical field of graphite electrodes, and relates to a superconductive graphite electrode nano antioxidant and a preparation method thereof. Background technique [0002] Graphite electrode is an important conductive material used in the field of metallurgy. Graphite electrodes are mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace. The strong current passes through the gas at the lower end of the electrode to generate arc discharge, and the heat generated by the arc is used. However, the structure of the graphite electrode is not an ideal lattice structure. It has certain lattice defects, and there are also some impurities, unsaturated bonds and internal stress. These parts have a relatively strong ability to absorb and react to oxygen. This provides active sites for graphite electrodes, and these active sites begin to undergo oxidation...
