Gelatin (GE), a nontoxic and degradable biomass resource, is a multistage hydrolysate of collagen. However, its application in adhesives was always limited by its brittleness and poor water resistance. In order to overcome this shortcoming, herein, epoxy-terminated hyperbranched polymers (EHPAEs) were first selected as a cross-linking agent to modify the GE extracted from leather solid wastes to prepare a series of novel GE-based environmentally friendly adhesives. First, EHPAE was synthesized and the structure of the hyperbranched polymer was measured by Fourier-transform infrared and 1H NMR spectroscopy. Then, the adhesives were obtained using the EHPAE to modify GE. The adhesion effect of the prepared adhesives was evaluated by tensile and T-peel tests on the surface of leather, in order to determine whether this adhesive achieved the quality requirements for footwear and bags. The result indicated that EHPAE-modified GE-based adhesives had higher solid content, superior adhesion ability, and water resistance. Moreover, the bonding layer of this adhesive was tough and ductile, while the bonding layers of the recently reported GE-based adhesives were brittle. This adhesive also surpassed the recently reported GE-based adhesives in terms of water resistance and adhesion performance.

具有超支化交联结构的新型基于明胶的环保胶粘剂
明胶（GE）是一种无毒且可降解的生物质资源，是胶原蛋白的多级水解产物。然而，其在胶粘剂中的应用总是受到其脆性和差的耐水性的限制。为了克服该缺点，本文首先选择环氧封端的超支化聚合物（EHPAE）作为交联剂，以改性从皮革固体废物中提取的GE，从而制备出一系列新型的基于GE的环保型粘合剂。首先，合成EHPAE，并通过傅立叶变换红外光谱和1测量超支化聚合物的结构。1 H NMR光谱。然后，使用EHPAE改性GE获得粘合剂。为了确定该粘合剂是否达到鞋类和箱包的质量要求，通过拉伸和T-剥离试验对制得的粘合剂的粘合效果进行了评估。结果表明，EHPAE改性的GE基胶粘剂具有较高的固含量，优异的粘合能力和耐水性。此外，该粘合剂的粘合层坚韧且易延展，而最近报道的基于GE的粘合剂的粘合层较脆。在耐水性和粘合性能方面，该粘合剂也超过了最近报道的基于GE的粘合剂。
