摘要：采用双氧水对非铬金属鞣制废革屑进行了催化氧化，制得降解产物（DCH），然后采用双醛海藻酸钠
（DSA）对 DCH 进行改性，获得生物基皮革填料（BDH）。采用 FTIR、GPC、XPS 和 Zeta 电位分析仪对 DCH
和 BDH 的结构和性质进行了表征。结果表明，DSA 对 DCH 成功进行了改性，BDH 的重均相对分子质量可由
DCH 的 3900 提升至 5570，同时其等电点由 5.2 调控至 3.3。填充实验表明，相较于未添加蛋白填料的革坯，DCH
和 BDH 填充革坯的各项性能明显更优，特别是抗张强度和丰满性；与 DCH 填充革坯相比，BDH 填充革坯的抗

Abstract: Non-chrome metal tanned waste leather shavings were catalytically oxidized by hydrogen
peroxide to prepare degraded collagen hydrolysate (DCH). Subsequently, the DCH was modified by
dialdehyde sodium alginate (DSA) to obtain bio-based protein filler (BDH). The structure and properties of
DCH and BDH were characterized by FTIR, GPC, XPS and Zeta potentiometric analyzer. The results
showed that DSA successfully modified DCH, and the weight-average relative molecular mass of BDH was
increased from 3900 of DCH to 5570 as well as the isoelectric point was changed from 5.2 to 3.3. The
properties of DCH and BDH filled crust leathers were significantly better than that of the crust leather
without filling by protein filler, especially the tensile strength and fullness. Compared with those of the
2
DCH filled crust leather, the tensile strength of BDH filled crust leather increased from 11.5 N/mm to
2
22.9 N/mm , the tear strength increased from 58.1 N/mm to 80.9 N/mm and the softness increased from
7.2 mm to 7.9 mm. Besides, the fullness of BDH filled crust leather was further improved. Overall, the
above-mentioned properties were better than those of crust leather filled using common commercial protein
filler.
