摘　　要：为资源化利用制革废弃蛋白质，采用环氧树脂为交联剂，交联水解胶原蛋白制备复鞣填充剂。研究表明，采用不同的环氧树脂，其交联程度不同。当丙三醇三缩水甘油醚的用量为水解胶原蛋白的15％～20％，在（50±5）℃、pH值8～9条件下反应5h时，水解胶原蛋白的交联程度达到90％，交联产物的分子质量明显增大，且该产物中不引入甲醛。交联产物用于制革复鞣填充时，其吸收率达到90％以上，对革的填充性显著，能有效减少皮革部位差。For the purpose of utilizing waste proteins in tanneries, the collagen hydrolysate was cross - linked by epoxy resin to prepare retanning and filling agent. It shows that the cross - linking degree greatly depends on the type of epoxy resins. Reacting with 15% - 20% glycerol epoxy resin under （50 ± 5 ）℃ and pH 8 - 9 for 5h, the cross - linking degree of collagen hydrolysate is up to 90%. The molecular weight of the cross - linked product is increased obviously, and the cross - linked product does not contain formaldehyde. When this cross - linked collagen hydrolysate is used as retanning and filling agent,its absorption extent in leather is higher than 90%. In addition, the prepared retanning and filling agent exhibites good filling behaviors and could effec- tively reduce the position difference of leather.
