摘　　要：本文应用自行研制的聚氨酯型金属铬(Ⅲ)络合物微乳液对生皮进行鞣制实验,制得皮革具有一定的机械强度、柔软性;其革鞣废液中残留的Cr(Ⅲ)浓度(最大为9.7mg/l)低于国家排放标准0.01g/L;场致发射扫描电镜(FE-SEM)的结果显示该络合物鞣剂可以良好地分散皮胶原纤维束,具有较好的鞣性。Leathers with and skins with the mechnical strength and flexibility were prepared by tanning hides synthesized polyurethane - chromium （ Ⅲ） complex tanning microemulsion. The concentration of Cr（Ⅲ） （if as high as 9.7 mg/l） in the waste tanning residues was still under the level of the Nation Standard （0.01 g/l）. The study of Scanning Electron Microscopy（FE-SEM） showed that the complex tanning agent could separate collagen fibres of the leather effectively and have better retanning effect.
