木质素在木材胶粘剂中的研究与应用

Research Progress and Applications of Lignins in Wood Adhesives

木质素是一种含量丰富的天然大分子材料,但由于其结构复杂,导致应用受到很大的限制。文章结合木质素的基本结构和化学改性,综述了其应用于酚醛树脂、脲醛树脂、三聚氰氨甲醛树脂和聚氨酯胶粘剂等常用木材胶粘剂及环保木材胶粘剂中的现状。

Lignin, the second abundant natural polymer, because of its complex structure, its applications were limited widely. Based on the fundamental structures of lignin and chemical modifications, the main present applications of industrial lignin in wood adhesives, together with conventional resins of wood adhesive, including phenol-formaldehyde, urea-formaldehyde, melamine-formaldehyde and polyurethane, as well as environmentally friendly wood adhesive were reviewed..
