The silicate-modified polyurethane material used for spraying to plug air leaks in coal mines has excellent adhesion, flame retardancy, water resistance, corrosion resistance, and a certain toughness. It can still plug air leaks and seal when deformed along with the rock layer and wall, and also has a certain reinforcement effect.
