The invention discloses a polyurethane hot-melt adhesive paint. The polyurethane hot-melt adhesive paint comprises at least one polyurethane prepolymer which is prepared by the reaction between a polyalcohol component and isocyanate. The preparation method comprises the following steps in sequence: feeding three polyester polyols, antioxidant and ultravioresistant agent into a reacting kettle based on the ratio; reacting; adding diisocyanate until the reaction is ended; and then adding chain extender and catalyst to react to obtain the polyurethane hot-melt adhesive paint. The polyurethane hot-melt adhesive paint is simple in preparation process, fast in surface drying speed, excellent in transparency, high in resistance to heat and UV (Ultraviolet), and excellent in environmental friendliness.
