摘　　要：用生物基产品取代石油基化学品对全球低碳经济的发展越来越重要。最新的生命周期评估表明,使用可再生的木质素替代苯酚生产酚醛树脂胶粘剂,可以显著减少碳排放和环境负面影响,对于加快“碳中和”目标的实现具有重要意义。然而,天然木质素固有的空间位阻大、结构不均匀性和低活性限制了其在胶粘剂中的应用,需要对木质素进行物理改性、化学改性和生物改性等活化方法来克服这些问题。本文主要综述了木质素的各种改性方法及其在酚醛树脂胶粘剂领城应用的最新进展。Replacing petroleum-based chemicals with bio-based products is increasingly important for the development of a global low-carbon economy.The latest life cycle assessment shows that using renewable lignin instead of phenol to produce phenolic resin adhesives can significantly reduce carbon emissions and environmen-tal negative impacts,which is of great significance to accelerate the realization of"carbon neutrality".However,the application of natural lignin in adhesives is limited because of its high steric hindrance,uneven structure and low activity.Many researchers developed the activation methods such as physical modification,chemical modifi-cation and biological modification to overcome these issues.This review mainly summarized the different modifi-cation of the lignin and their application in the adhesive area.
