摘要:当前，从制浆造纸工业黑液中回收的木质素主要用于生产混凝土减水剂、石油开采助剂、农药增效剂、分散剂等，但产品附加值不高。本文介绍了将工业木质素用于生产木质素基双酚A型环氧树脂的研究进展。主要生产方法包括木质素及其衍生物与环氧树脂直接共混固化、木质素及其衍生物环氧化合成环氧树脂和木质素及其衍生物官能化改性后合成环氧树脂。

Abstract:As a natural polymer, lignin is characteristic of great abundance, renewability and degradabilityin nature.The lignin recovered from the wastestream of pulp and paper industry is mainly used in the production of concrete water-reducing admixture, petroleum extraction aid, pesticide synergists, dispersants, etc. However the added-value of these products is very low. This review summarized the research progress regarding to lignin-based bisphenol A type epoxy resin and focused on its main preparation methods especially direct blending and curing of lignin and epoxy resin， synthesis of epoxy resin by lignin epoxidation and modified lignin based epoxy resin．
