Polyurethane cement composite repairing material
The invention discloses a polyurethane cement composite repairing material. The polyurethane cement composite repairing material comprises a component A, a component B and a component C, wherein the component A comprises polymethylene polyphenyl isocyanate and diphenyl methane diisocyanate; the component B comprises polyol, a polyurethane defoaming agent, an oxazolidine water removal agent, waterand a molecular sieve; and the component C comprises cement and ground calcium carbonate powder. The polyurethane cement composite repairing material can be quickly cured, is high in strength, does not foam when meeting water, is high in volume stability and good in durability, and can be used for slurry-turning and mud-overflowing treatment of railroad bed sections, ballasted tracks and ballast-less tracks and treatment of slurry-turning and mud-overflowing of highways.
本发明公开了一种聚氨酯水泥复合修补材料，包括：A组分、B组分和C组分；A组分包括多亚甲基多苯基异氰酸酯和二苯基甲烷二异氰酸酯；B组分包括多元醇、聚氨酯消泡剂、噁唑烷除水剂、水和分子筛；C组分包括水泥和重钙粉。本发明的聚氨酯水泥复合修补材料能够快速固化、强度高、遇水不发泡、体积稳定性高、耐久性好，可用于铁路路基段、有砟轨道和无砟轨道翻浆冒泥整治和高速公路翻浆冒泥的整治。
