Zusammenfassung:The invention discloses a water-soluble polyurethane corrosion inhibitor and a preparation method and application thereof. The preparation method includes the steps that by weight, 10-30 parts of polyethylene glycol compounds are dissolved in an organic solvent, then 20-60 parts of cyanate ester compounds and 1-3 parts of catalysts are added, and a mixing reaction is conducted at 15-80 DEG C to obtain a first reaction mixture; and 10-30 parts of aniline low polymers are added into the first reaction mixture to conduct a reaction at 20-100 DEG C, and aftertreatment is conducted to obtain the water-soluble polyurethane corrosion inhibitor. The preparation process of the novel water-soluble polyurethane corrosion inhibitor is simple, the raw materials are cheap and easy to obtain, and the obtained water-soluble polyurethane corrosion inhibitor is simple in using method, can be used after being diluted by water, and is long in slow release time, stable, safe, environmentally friendly, low in consumption and good
