摘　　要：基于环保和可持续发展理念,生物基产品可以实现可再生和降低对环境的影响。水性聚氨酯在皮革涂饰剂领域所用的材料都是石油基产品。本文以异佛尔酮二异氰酸酯(IPDI)、生物基聚四氢呋喃醚二元醇(Bio-based PTMEG)、亲水扩链剂二羟甲基丁酸(DMBA)、小分子扩链剂新戊二醇(NPG)、异佛尔酮二胺(IPDA)等材料合成生物基水性聚氨酯树脂。利用红外光谱(FTIR)、差示扫描量热法(DSC)、拉力试验机和热失重测试(TGA)等仪器对水性聚氨酯进行表征和性能研究。试验结果表明,制备的生物基聚氨酯有较好的拉伸强度、断裂伸长率和耐水性。Based on environmental protection and the concept of sustainable development,bio-based products can be renewable and reduce the impact on the environment.The materials used in the leather finishing field of waterborne polyurethane are all petroleum-based products.In this paper,the isophorone waterborne polyurethane resins were syn-thesized from isocyanate diisocyanate(IPDI),bio-based PTMEG,hydrophilic chain extender dimethylbutyric acid(DMBA),small molecule chain extender neopentyl glycol(NPG)and isophorone diamine(IPDA).The properties of waterborne polyurethane were characterized by FTIR,differential scanning calorimetry(DSC),tensile tester and TGA.The experimental results show that the prepared biological polyurethane has good tensile strength,elongation at break and water resistance.
