近年来，由于皮革清洁剂生产的环保要求越来越坚韧，无毒和可生物降解的复鞣剂受到越来越多的关注。以水解胶原蛋白和氧化橡提取物为原料，制备了一种新型的生物质两性复鞣剂，该复鞣剂能显著降低游离甲醛的含量。以含铬废革为原料，采用原位水解法提取胶原蛋白，并将橡提取液经漆酶催化后得到氧化橡提取液。漆酶催化的橡提取物与水解的胶原蛋白发生Schiff碱反应。值得注意的是，使用氧化橡属提取物改性的胶原复鞣剂复鞣的皮革是相当的，并且超过了市售的戊二醛改性的胶原复鞣剂，表现出上级的收缩温度、厚度、机械性能、染色性能和游离甲醛去除功能（游离甲醛去除率为70.2%）。本研究为制备性能优异的多功能无毒两性复鞣剂提供了一种方法，为皮革的可持续发展提供了一种途径。
Non-toxic and biodegradable retanning agents have received increasing attention over recent years driven by the tough environmental targets for leather cleaner manufacturing. Herein, a novel biomass-based amphoteric retanning agent, which can reduce free formaldehyde significantly, was prepared using hydrolyzed collagen and oxidized valonia extract as the raw materials. In this investigation, collagen was derived from chromium-containing waste leather byin situhydrolysis, and oxidized valonia extract was obtained after laccase catalysis of valonia extract. A Schiff’s base reaction occurred between the laccase-catalyzed valonia extract and hydrolyzed collagen. Notably, the leather retanned using the oxidized valonia extract modified collagen retanning agent was comparable and surpassed a market glutaraldehyde modified collagen retanning agent exhibiting superior shrinkage temperature, thickness, mechanical properties, dyeing properties and free formaldehyde removal function (free formaldehyde removal rate is 70.2%). This study provides a method for preparing an outstanding multifunctional non-toxic amphoteric retanning agent and offers a method for sustainable development of leather.
