采用桉木纤维为原料，探讨碱处理对板材挤压结合机理的影响。结果表明：碱处理对木质素、半纤维素都有不同程度的降解作用；在热压制板过程中，经过降解作用的木材成分经适当的热压工艺能够发生聚合反应从而粘合成板；强碱（NaOH）对桉木纤维的影响大于弱碱溶液（Na2CO3），且处理时间为10 h 较适宜；碱处理过程产生的活性羟基，热压后可以缔合形成氢键，增加了纤维之间的结合力，有利于桉木纤维自身粘合成板。

Eucalyptus wood fiber was prepared to investigate the effects of alkali treatment on mechanism of extrusion bonding of the board. The results showed that hemi-cellulose and lignin were partly degraded during eucalyptus wood fiber were treated with alkali，these degraded substances could be copolymerized during hot-pressing，the influence of alkali (NaOH) on eucalyptus wood fiber was greater than the weak base (Na2CO3) and the processing time for 10 h was more appropriate，and the increased hydroxyl after defibrinating partly formed hydrogen-bonding during hot-pressing，resulting in strengthened fiber self-bonding.
