Polypropylene crosslinking copolymer fiber concrete leaking stoppage paste
The invention discloses polypropylene crosslinking copolymer fiber concrete leaking stoppage paste which comprises earlier-stage leaking stoppage paste and later-stage leaking stoppage paste. The earlier-stage leaking stoppage paste is composed of the following components of, by weight, 3 to 5 parts of a composite filling agent, 4 to 5 parts of a composite reinforcement agent, 2.5 to 3 parts of sodium polyacrylate crosslinking copolymer particles, 5 to 6 parts of flax fibers, 0.5 to 1 part of saw powder and 80 to 85 parts of water. The later-stage leaking stoppage paste is composed of the following components of, by weight, 20 to 30 parts of silicate cement, 5 to 10 parts of sodium polyacrylate crosslinking copolymer particles, 5 to 15 parts of flax fibers, 15 to 20 parts of medium sand and 5 to 10 parts of water. According to the leaking stoppage paste, a bridge connection leaking stoppage method and a chemical leaking stoppage method are combined, leaking stoppage risks are reduced, the leaking stoppage effect is improved, and meanwhile cost is low.
