The invention provides a floral-scented anionic water-based polyurethane resin and its use in leather. The floral-scented anionic water-based polyurethane resin is subjected to anionic chain extension of a prepolymer formed by a macromolecular polyol and an aromatic polyisocyanate through hydroxycitronellol, so as to obtain the floral-scented anionic water-based polyurethane resin; The weight ratio % among the malol, the macromolecular polyol, and the aromatic polyisocyanate is: (70-85): (20-30): (2-10). The floral-scented anionic water-based polyurethane resin according to the present invention is safe and environmentally friendly, can stably volatilize scent, and makes the production process simpler and more efficient. |
