The invention relates to a wet-type ironing color-changing polyurethane resin and a preparation method thereof. The preparation method comprises the following steps of: mixing and stirring a polyol compound, a dihydric alcohol chain extender, an antioxidant and part of solvent; adding diisocyanate and a catalyst stepwise into the mixed solution to perform a reaction; and adding the solvent into the mixed solution according to the change of the viscosity of a system so as to control the viscosity to reach a range meeting requirements at last. The wet-type ironing color-changing polyurethane resin completely solves the problems that the conventional common polyurethane resin is difficult to iron to change color at a high temperature and the stability of the color is not high. Synthetic leather manufactured by the wet-type ironing color-changing polyurethane resin can be ironed to change color easily at a high temperature and the stability of the color is high.
