摘要：以天然可再生资源替代传统化石资源开发绿色环保、性能优异的木材胶黏剂是人造板行业研究的热点。木质素来源广泛、价格低廉,且分子结构中含有羟基、甲氧基、羧基等活性基团,易于功能化修饰,是合成木材胶黏剂的理想原料。本文重点综述了木质素及其衍生物在酚醛树脂、脲醛树脂、环氧树脂、聚氨酯等合成树脂木材胶黏剂中的应用与研究现状,介绍了化学改性、降解、溶剂分级纯化等预处理方式对木质素化学反应活性及合成树脂胶黏剂力学性能的影响,探讨了木质素基木材胶黏剂目前发展面临的困难和挑战,并展望了未来应用及研究方向,以期为木质素资源的高效、高值化综合利用及高性能生物基木材胶黏剂的开发提供理论与技术参考。
The development of eco-friendly and excellent wood adhesive from sustainable and renewable resources instead of traditional fossil resources had attracted considerable attention in the wood-based panel industry.Lignin had a wide range of sources and low prices,and its molecular structure contained active groups,such as hydroxyl,methoxyl and carboxyl groups,which were easy to be functionalized and modified,and it was an ideal raw material for making wood adhesive.In this paper,the applications and research status of lignin and its derivatives in wood adhesives of phenolic resins,urea-formaldehyde resins,epoxy resins and polyurethanes and other synthetic resins were reviewed.Furthermore,the effects of pretreatment methods such as chemical modification,depolymerization and solvent fraction on the chemical reactivity of lignin and the mechanical properties of synthetic resin adhesives were discussed.The problems and challenges of lignin-based wood adhesives existed in the current development of were investigated,and the future application and research directions were prospected,in order to provide theoretical and technical references for the efficient and high-value added utilization of lignin resources and the development of high-performance bio-based wood adhesives.
