▎ 摘  要

NOVELTY - Graphene modified resistance reduction material comprises 20-50 pts. wt. cement, 20-40 pts. wt. crystalline flake graphite, 0.01-4 pts. wt. graphene, 1-10 pts. wt. carbon fiber, 1-10 pts. wt. zinc powder, 1-10 pts. wt. dispersant, 1-10 pts. wt. steel fiber, 10-30 pts. wt. bentonite, and 0.5-2 pts. wt. calcined gypsum. USE - Used as graphene modified resistance reduction material. ADVANTAGE - The material has low resistivity, high mechanical property, good corrosion-proof performance, and simple construction method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene modified resistance reduction material, comprising (i) selecting graphene, dispersant and water to form a graphene dispersion, the ratio of graphene to water is between 1:20 and 1:30, performing ultrasonic treatment for 2 hours, and stirring uniformly, (ii) adding bentonite and gypsum gypsum satisfying the ratio of the ratio to the mixed liquid, and mechanically stirring for 1 hour to reach a uniform state, (iii) mechanically stirring for 1 hour to achieve a homogeneous state, mixing zinc powder with the crystalline flake graphite for 1 hour to uniform state, adding the mixing material in the mixed slurry, stirring for 1 hour to reach uniform state, and (iv) stirring slurry uniformly, pouring into a mold, allowing to stand for 24 hours, and curing.
