壳聚糖基胶黏剂用于木材黏合剂领域的研究现状

Research Status of Chitosan Based Adhesives Used in Wood Adhesives

壳聚糖是一种具有大量储量的生物质,因其在黏合剂应用方面具有潜在的优良品质,是黏合剂领域最引人注目的生物聚合物之一。但在正常、潮湿条件下,其胶合强度不足以胶合木材。在木质复合材料生产中,壳聚糖可以清除甲醛。介绍了用于壳聚糖改性的各种交联剂。

Chitosan is a biomass substance having a lot of reserves.It is one of the most interesting biopolymers in adhesives due to its potentially excellent qualities in adhesive application.However,under normal and wet conditions,its bonding strength is not enough to glue wood.In the production of wood composites,chitosan can also scavenge formaldehyde.The study introduces various crosslinking agents for chitosan modification.
