【摘要】 研究了从含铬皮革废弃物中提取胶原蛋白,再用氨基树脂进行改性,制备得到稳定的氨基树脂改性胶原蛋白复鞣剂,并将制备的复鞣剂在羊皮的复鞣工序中进行应用。结果表明:该路线切实可行,所得复鞣剂具有胶原蛋白的两性结构,复鞣时不会造成坯革的“败色”现象,并且手感自然舒适柔软、无塑料感,可以有效提高含铬皮革废弃物的利用率。更多还原

【Abstract】 Amine resin modified collagen protein retanning agent was prepared by isolating collagen protein from chrome-containing leather waste and reacting collagen protein with amine resin, and the retanning agent was applied in the retanning of sheepskin. The results show that the method is feasible and the retanning agent of amphoteric structure has the advantages of less whiten defect and good hand feeling, which is beneficial for the reuse of leather wastes.更多还原
