摘　　要：采用含氟水性丙烯酸酯改性聚氨酯(PUA)作为合成革表面的涂饰剂,利用干法转移涂层和辊涂处理两种工艺方法分别制备了含氟水性PUA合成革,探讨了涂膜表面的性能。实验表明,含氟水性PUA的涂膜表面具有良好的剥离负荷和撕裂负荷及耐溶剂性;耐磨、耐水解性能与传统溶剂型聚氨酯表面涂饰剂相近。这不仅能环保、洁净生产,而且对合成革用聚氨酯从溶剂型向水性的变革具有现实意义。Using the acrylic-modified waterborne polyurethane （PUA） which contained fluorin material as the coating agent of the synthetic leather, through release paper method and rolling technique on the surface of the leather, a kind of synthetic leather of fluorine modified PUA coating was produced. The film mechanics perform- ance was discussed. The resulted showed that PUA coating modified by fluorine had good peel strength, tear strength and solvent resistance. The abrasion resistance and hydrolysis resistance were nearly same as the traditional solvent-type leather. This technique not only had benefit of environment and cleaning manufacture, but also had great function of transforming from solvent-type to waterbased in the PU synthetic leather coating.
