改性淀粉在木材胶粘剂中的应用研究进展

摘要

淀粉在胶粘剂领域占有重要地位.经过氧化改性后,在淀粉分子链上引入大量分布均匀的化学键与氢键结合,改善耐水性,更能满足木材胶粘剂行业要求.文章综述了淀粉改性后在水性高分子-异氰酸酯（API）胶粘剂、聚乙酸乙烯酯胶粘剂和三聚氰胺-甲醛胶粘剂中作为木材胶粘剂的应用,分析了研究现状,探讨了发展趋势和研究方向.%The starch plays an important role in the field of wood adhesive.Most of the modification of starch are trying to make the full use of macromolecular chains of the starch and to connect chemical bonds evenly on the chain in order to enhance the water resistance and to meet the professional requirements in the wood adhesive industry.It is mainly summed that the modified starch is widely used in wood adhesive and the progress of application in polymer-isocyanate adhesive for wood splice,polyvinyl acetate emulsion,melamine-formaldehyde wood adhesive.Then,the present progress of the research,the tendency and prospect of modified starch on wood adhesive have been discussed in the paper.
