▎ 摘 要
NOVELTY - Superconducting graphite electrode nano-antioxidant comprises 80-100 pts. wt., preferably 90 pts. wt. water, 20-40 pts. wt., preferably 30 pts. wt. ceramic powder, 20-25 pts. wt., preferably 22 pts. wt. graphene, 10-25 pts. wt., preferably 20 pts. wt. polyethylene glycol, 6-12 pts. wt., preferably 10 pts. wt. stabilizer, 5-10 pts. wt., preferably 8 pts. wt. antioxidant auxiliary agent and 10-15 pts. wt., preferably 12 pts. wt. polyvinyl alcohol. The anti-oxidation auxiliary agent comprises calcium boride, vanadium diboride and sodium dihydrogen phosphate in a mass ratio of 2:0.8-1.2:1, preferably 2:1:1. The stabilizer comprises meglumine and zirconium nitride in a mass ratio of 1-1.32:1, preferably 1.2:1. The ceramic powder comprises 10-20 pts. wt., preferably 15 pts. wt. cerium (IV) oxide, 10-15 pts. wt., preferably 12 pts. wt. titanium dioxide and 10-15 pts. wt., preferably 8 pts. wt. aluminum oxide. USE - Used as superconducting graphite electrode nano-antioxidant. ADVANTAGE - The nano-antioxidant: solves the problem of insufficient antioxidant property of the graphite electrode nano-antioxidant in the prior art. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the superconducting graphite electrode nano-antioxidant, comprising: (i) grinding the ceramic powder to a grain diameter of 50-100 nm, adding polyethylene glycol to obtain a ceramic powder slurry; (ii) adding the ceramic powder slurry and graphene into a solvent i.e. water to obtain pre-mixed liquid; and (iii) orderly adding antioxidant auxiliary agent, stabilizer and polyvinyl alcohol into the pre-mixed liquid to obtain superconducting graphite electrode nano-antioxidant.
