Graphene modified resistance-reducing material and preparation method thereof
The invention relates to the field of resistance reducing materials, in particular to a graphene modified resistance reducing material and a preparation method thereof.The graphene modified resistance reducing material is prepared from, by weight, 20-50 parts of graphene, 10-20 parts of conductive particles, 20-35 parts of sodium bentonite, 10-50 parts of a surfactant, 1-10 parts of a dispersing agent, 1-10 parts of conductive fibers, 20-60 parts of a wetting agent, 1-5 parts of sodium molybdate and 20-80 parts of cement. Graphene is uniformly added into a resistance reducing material, cement is generally added into a physical resistance reducing material to serve as a filler, and graphene has a template effect on formation of a cement hydration crystal product, so that the cement hydration product can be promoted to form regular nanoscale microcrystals; therefore, the comprehensive properties such as strength, toughness, conductivity and corrosion resistance of a cement matrix are remarkably improved; and meanwhile, the conductive particles and the conductive fibers can provide conductivity, so that the use effect is enhanced.
