NOVELTY - Flame retardant antistatic large deformation spraying plugging air leakage material comprises 47-65 parts mass polymer emulsion, 6-24 parts mass inorganic filler, 28-41 parts mass flame retardant, 0.02-0.06 parts mass graphene, 0.04-0.08 parts mass antistatic agent and 0.9-2.9 parts mass admixture. USE - Flame retardant antistatic large deformation spraying plugging air leakage material. ADVANTAGE - The material has low cost, strong cohesive force and high sealing performance, can be attached to the surface of coal and rock mass, concrete, metal and wood, and can effectively seal the surface cracks under the mine and isolate the gas flow. The amount of deformation is large, and the material is not easy to crack, and has high strain capacity for dynamic deformation of the roadway surface, and simultaneously, has excellent flame retardancy and antistatic properties, safe and reliable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the flame retardant antistatic large deformation spraying plugging air leakage material, involving (a) mixing graphene, antistatic agent, admixture and polymer emulsion to obtain component A, (b) mixing the flame retardant with the inorganic filler to obtain component B, and (c) mixing component A and component B to obtain a flame retardant antistatic large deformation spray plugging air leakage material.
