The invention discloses an inorganic-organic composite grouting water-stop material, a preparation method and an application thereof. ~20 parts, 0.1-0.3 parts of crosslinking agent, 0.1-0.5 parts of initiator, 0.2-1.0 parts of dry ice, 30-40 parts of water. The machine-organic composite grouting water-stop material of the invention has good flexibility, cohesiveness, and repeated water swelling. The inorganic grouting materials are modified by the good cohesiveness, toughness and water-swelling properties of organic polymers, and the pH value environment of the slurry in the early stage of cement hydration is improved by using dry ice, so that the polymer has a higher degree of polymerization and better performance. . This technology not only gives full play to the advantages of high strength and low cost of inorganic grouting materials, but also endows them with good adhesion, toughness and water swellability. |
