上述皮革表面处理剂具体制备工艺如下：
（1）先将高碳醇磺基琥珀酸酯、聚四亚甲基醚二醇投入反应釜中，加热到110～120℃，然后抽真空脱水30～60分钟；
（2）将上述混合物降温到85℃，加入有机铋崔化剂搅拌10分钟；
（3）再向上述混合物中加入异佛尔酮二异氰酸酯，维持温度70～90℃保温120～180分钟；
（4）然后在上述温合物中加入丁二醇、二羟甲基丙酸及适量的丙酮，维持温度70～90℃保温180～240分钟继续反应；取样检测异氰酸酯基含量（NCO），使其含量维持在0.5～4.3%；
（5）然后将上述混合物冷却到40℃，加入脂肪醇聚氧乙烯醚及丙酮，搅拌10～30分钟；
（6）在上述搅拌的同时，加入已混合卵磷脂的去离子水；
（7）继续搅拌60～120分钟，真空抽去丙酮，即可得到成品。
本发明的有益效果在于：用上述方法生产成的皮革表面处理剂具有柔软性好，耐光性、耐水性好，伸长率达到1000～1500%，用该涂料处理过的皮革具有极佳的柔顺手感，耐化学性，耐磨，具有高拉伸，高伸长率，耐水耐湿，抗紫外线，不黄变、高光；本涂料树脂对TPU，PU革，PVC，PC，尼龙布，莱卡，高弹力布附着力佳。
