Chemical grouting material for coal-rock mass water shutoff and reinforcement and preparation method thereof
The invention belongs to the field of chemical synthesis, and particularly relates to a novel chemical grouting material for coal-rock mass water shutoff and reinforcement and a preparation method thereof. The chemical grouting material provided by the invention is prepared by mixing a component A and a component B at a volume ratio of 1:1, wherein the component A is prepared by proportionally mixing liquid sodium silicate, small-molecular alcohol and a catalyst; and the component B is prepared by proportionally mixing polyphenyl polymethylene polyisocyanate and a viscosity reducer. The chemical grouting material provided by the invention has the characteristics of low raw material cost, good permeability, fast curing, high adhesive force with a coal bed and high solidification strength; and particularly, the material does not foam in water, the water shutoff and reinforcement effects can be perfectly realized, the related raw materials are green and pollution-free, and the material does not contain volatile solvents or generate any poisonous gas and completely meets the requirements in use and environmental protection of coal mine water shutoff and reinforcement materials.
