木质素聚氨酯涂料的研究进展

Research progress in lignin-based polyurethane coatings

对近年来木质素聚氨酯涂料的研究进展进行了综述。介绍了木质素的结构和不同种类木质素聚氨酯涂料。针对木质素聚氨酯涂料制备过程中存在的问题,从木质素的分离和改性以及如何与异氰酸酯更好地聚合等方面提出了展望,以期为木质素在聚氨酯涂料领域的高效利用提供有益参考。

This paper reviews the research progress in lignin-based polyurethane coatings in recent years,and introduces the structure of lignin and lignin-based polyurethane coatings.In the light of the problems existed in the preparation process of lignin-based polyurethane coatings,some prospects are given from the separation and modification of lignin as well as the way to polymerize lignin with isocyanate well,aiming to provide useful references for the efficient utilization of lignin in the field of polyurethane coatings.
