竹材酚醇液化及其应用研究进展

Research Progress on Liquefaction of Bamboo in Phenol and Polyhydric Alcohols and Its Application

竹材酚醇液化是竹材综合利用的有效方法之一,通过溶剂反应破坏竹材纤维素的结晶结构、半纤维素和木质素高分子结构,使其分子链断裂,降解成带有反应活性的羟基化合物,可以用于制作胶黏剂、发泡材料和碳纤维等。文章分析了竹材液化原理、酚醇液化技术,以及竹材酚醇液化产物的应用研究现状,认为该领域今后需要加强基础理论和预处理技术的研究,尽快制定相关产品标准,实现竹材资源的高利用率和高附加值。

Liquefaction of bamboo in phenol and polyhydric alcohols（ abbreviation： LB- PPA） is one of the effective methods for improved comprehensive utilization of bamboo. The molecular chain is ruptured by damaging crystallization structure of cellulose,hemicellulose and lignin macromolecule structure through solvent reaction,which makes bamboo degraded into hydroxyl compounds with active reactions. The products can be used as adhesives,foaming materials,carbon fiber,etc. This paper analyzed the bamboo liquefaction principle,liquefaction technology,and the applied study of bamboo liquefied products. Future studies should be more focused on the basic theory and pretreatment technique,and relevant product standards should be formulated so as to realize high utilization rate and high added value of bamboo resources.
