摘　　要：以异氰酸酯与含活泼氢化合物的聚醚多元醇为主要原料,合成端—NCO预聚体,由此预聚体配和相关添加剂制成的"氰凝"堵漏浆料,可用于各种裂缝和孔隙的充填,或直接用于基面涂装,具有抗渗、防水的功效。介绍了产品原材料的选择和制备工艺过程的控制。Based on isocyanate prepolymer and polyether polyols containing active hydrogen compounds as the main raw material, end -NCO prepolymers was prepared. The cyanogen coagulant slurry made of this prepolymers and related additives could be used for gap filling or base coating. It had anti-permeability and waterproof effect. The selection of raw materials and control of preparation process were introduced.
