Improving the environmental performance of resins in wood treatment by using renewable chemicals has been a topic of interest for a long time. At the same time, lignin, the second most abundant biomass on earth, is produced in large scale as a side product and mainly used energetically. The use of lignin in wood adhesives or for wood modification has received a lot of scientific attention. Despite this, there are only few lignin-derived wood products commercially available. This review provides a summary of the research on lignin application in wood adhesives, as well as for wood modification. The research on the use of uncleaved lignin and of cleavage products of lignin is reviewed. Finally, the current state of the art of commercialization of lignin-derived wood products is presented.
长期以来,通过使用可再生化学品来提高木材处理中树脂的环境性能一直是人们感兴趣的话题。与此同时,木质素作为地球上第二丰富的生物质,作为副产品被大规模生产,主要用于能源领域。木质素在木材胶粘剂或木材改性中的应用受到了很多科学关注。尽管如此,市场上仅有少数几种木质素衍生的木制品。本综述总结了木质素在木材胶粘剂以及木材改性方面的应用研究。文中对未裂解木质素和木质素裂解产物的使用研究进行了综述。最后,介绍了木质素衍生木制品的商业化现状。
