NOVELTY - Graphene caulking water stop material, obtained by obtaining the slurry to be polymerized by mixing an acrylic monomer, an acrylamide, and a crosslinking agent, atomizing by a high-speed nozzle, colliding, mixing with the activated carbon complex particles supporting graphene, using electron irradiation to carry out the polymerization reaction and kneading with natural rubber and filler. USE - The graphene caulking water stop material is useful for building caulking (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene caulking water stopping material, comprising (i) adding graphene and activated carbon having a particle diameter of 1500-2000 to water, carrying out ultrasonic dispersion treatment, filtering, washing and drying to obtain graphene-loaded activated carbon complex particles, (ii) adding an acrylic monomer, an acrylamide, a crosslinking agent to the mixing kettle and stirring uniformly to obtain a slurry to be polymerized, (iii) placing the slurry to be polymerized in a fluidized bed, spraying by a high-speed nozzle, colliding with the activated carbon complex particles fed by the pressure conveying device, turning on the electron beam after the contact of the two materials, irradiating the electron beam, polymerizing the polymerization slurry, collecting and drying to obtain complex gel particles containing activated carbon and (iv) adding the natural rubber, gel particles and filler into the open mill for kneading.
