Beschreibung
Zusammenfassung:	The invention relates to a polyurethane material capable of being bonded on a wet interface as well as a preparation method and application of the polyurethane material. The polyurethane material is prepared from a material A and a material B in a mass ratio of (0.9: 1)-(1.2: 1), the material A comprises the following components in parts by mass: 90-110 parts of polyol, 1-2 parts of a composite catalyst, 20-30 parts of a water repellent agent, 1-2 parts of an anti-aging agent and 1-2 parts of a water absorbent; the material B comprises the following components in parts by mass: 90-110 parts of an isocyanate prepolymer, 3-5 parts of a water absorbent and 10-20 parts of a water repellent agent; the composite catalyst is composed of dibutyltin dilaurate, strontium chloride, rhodium chloride and aluminum chloride in a mass ratio of (12-18): (18-22): (28-32): (23-28). Experiments on the bonding strength of the polyurethane material on a wet interface show that the material has great application value in the fields
