The invention provides a special POZD repairing material for drinking water facilities, and a preparation method and a repairing construction method thereof, belonging to the technical field of repairing materials. The special POZD repairing material does not contain solvents and heavy metal catalysts, is free of pollution to drinking water, has good adhesion to a substrate to be repaired and canbe applied to local rapid repairing of water-containing facilities such as drinking water conveying pipelines, aquariums and reservoirs. The repairing material comprises a component A and a componentB in a weight ratio of 0.8: 1 to 1.5: 1. The component A comprises 40-96 parts of aliphatic isocyanate, 2.1-10 parts of epoxy resin, 68-150 parts of polyether polyol and 0-10 parts of a hindered aminechain extender, wherein, the aliphatic isocyanate has a carbon number of 10-20, and the polyether polyol has a molecular weight of 1000-4000. The component B includes 5-20 parts of a hindered amine chain extender, 40-120 parts of difunctional amino-terminated polyether, and 25-89 parts of trifunctional amino-terminated polyether.
