中文摘要

考察了实验室自制胶原蛋白基氨基树脂(MCL)、胶原蛋白基丙烯酸树脂(NCL)、胶原蛋白基超支化树脂(HCL)和脂肪族胶原蛋白基树脂(ACL)四种皮革填充材料的稳定性及在黄牛鞋面革的填充工序中的应用性能。实验结果表明:四种材料与盐、醛、丙烯酸树脂均具有良好的混溶性,与缩合类型栲胶(杨梅栲胶、荆树皮栲胶)混合有絮凝。在皮革的填充应用中,MCL对坯革的增厚效果明显;ACL和NCL能够明显提高坯革的收缩温度;HCL使坯革的抗张强度提升35.9%;ACL使坯革的撕裂强度提升40.0%且能促进对染料的吸收,废水中的总有机碳降低29.5%。

英文摘要

In this paper, four kinds of collagen-based leather filling materials, namely collagen-based amino resin (MCL), collagen-based acrylic resin (NCL), collagen-based hyperbranched resin (HCL), and aliphatic collagen-based resin (ACL) were prepared by our laboratory and applied in filling process of cattle upper leather. Herein, the stability of the four materials and the physical and mechanical properties of retanned leather using these four materials were detailed evaluated. The experimental results showed that all the four materials had excellent compatibility with salt, aldehyde and acrylic resin, and have certain flocculation with condensed tannin (chinese bayberry extract, wattle extract). When these four materials are applied in filling process, compared with the controlled leather, the leather filled with MCL felt more tight and had obvious thickening effect. Moreover, shrinkage temperature of the leather filled with ACL and NCL increased significantly. The tensile strength of the leather filled with HCL increased by 35.9%. The tear strength of the leather filled with ACL increased by 40.0%, and the usage of ACL can promote the absorption of dyes, the total organic carbon in wastewater reduced by 29.5%.
