木质素在合成聚氨酯中的应用

Application of Lignin in Synthesis of Polyurethane

木质素作为一种天然可再生资源,其研究和应用日益活跃。在材料中引入木质素,不仅可提高材料的性能,还能降低成本,产生可观的经济效益。文章综述了国内外以木质素、改性木质素代替多元醇为原料合成聚氨酯材料的一些探索性研究和应用,对木质素在聚氨酯泡沫、聚氨酯薄膜、聚氨酯黏胶剂以及聚氨酯涂料等方面进行了阐述;并针对木质素的结构和性能,提出了改性木质素将成为木质素基聚氨酯的研究重点。

The research and application of lignin which is one of renewable natural resources become more and more active.The introduction of lignin into materials may not only enhances its properties,but also can lower the costs.In this review,the explo-ratory development and application progress of using lignin or modified lignin to replace parts of polyols in the field of polyurethane synthesis are presented such as polyurethane in foam,film,adhesive and paints.Research on lignin-modified polyurethane will become the focus in connection with its structure and properties.
