Application Research of Lignin in Resin Adhesive

木质素的化学反应活性主要与结构单元中酚羟基、醇羟基和酚羟基邻、对位活泼氢的含量有关。利用可再生无毒的木质素替代苯酚用于胶粘剂制备，既能减少化石原料的使用，又达到变废为宝，实现资源化治理的目的。重点介绍了木质素酚醛树脂研究进展，评述了木质素酚醛树脂的最新成果，以及木质素酚醛树脂存在的问题，展望了木质素在胶粘剂领域应用的发展方向。 The chemical reaction activity of lignin is mainly related to the content of phenolic hydroxyl group, alcoholic hydroxyl group and phenolic hydroxyl group ortho, and para-active hydrogen. The use of renewable wood non-toxic in substitute for phenol adhesive preparation can reduce the use of fossil fuels, and realize the purpose of changing the resource waste to treasure. In this paper, the research progress of lignin phenolic resin was introduced, and the latest results of lignin phenolic resin were reviewed. The problems existing in the formaldehyde resin and the development direction of Lignin Application in adhesive field were prospected.
