摘要
木质素由于化学结构与苯酚相似,通过活化改性可部分替代苯酚制备木质素改性酚醛树脂胶黏剂。既可降低成本、达到生物质资源高效利用的目的,并且制备的木质素改性酚醛树脂胶黏剂有毒残余较低,具有环保意义,是合成制备生物质高分子材料的重要途径。本文综述了国内外研究人员在木质素活化改性制备酚醛树脂胶黏剂研究领域的最新进展,重点介绍了化学改性、物理改性、生物改性等木质素活化改性方法,比较了不同改性产物制备酚醛树脂胶黏剂的性能,并对影响木质素活化改性制备酚醛树脂胶黏剂实现工业化应用的主要因素进行了分析。
As a important way to syntheSize biopolymer described by many researchers, lignin can be used to replace with phenol to prepare phenolic resin after active modification due to the similar structure to phenol. The lignin-modified phenolic resin can not only resduce the cost but also achieve the purpose of utilization of biomass resources. It has lower toxic residue with environmental importance. In this paper, the latest progress in study of phenolic resin adhesive modified by lignin was reviewd. Especially, the chemical, physical, biological methods for lignin active modification was described by showing the porpertis of adhesive with comparing them. After analysis in technology difficulties, it is summarized the main factors affected feasibility of the industrial application of phenilic resin adhesive modified by lignin.
