耐光水乳型聚氨酯—脲皮革涂饰剂的研究

Study on Lightfast Polyurethane_urea Finish in Aqueous Emulsion

选择脂肪族二异氰酸酯，通过酮连氮法制备水乳型聚氨酯—脲皮革涂饰剂。它的涂层具有优异的机械性能和耐黄变、耐有机溶剂和水。

Polyurethane_urea used for leather finishing was prepared from aliphatic diisocyanate by ketazine process. Its coatings have excellent mechanical properties, best resistance to yellowing, and good fastness to solvents and water.
