摘　　要：[目的]为速生桉树木材液化及其产物的应用提供参考。[方法]以硫酸为催化剂,苯酚为液化剂,对速生人工林桉树木材进行液化,并取液化产物与甲醛进行树脂化反应制备液化木基酚醛树脂LWPF,研究液比对液化反应效率、液化产物重均分子量及LWPF树脂胶合性能的影响。[结果]随着液比的提高,液化产物的残渣率及重均分子量均降低,而LWPF树脂制得的胶合板的木破率提高;当液比提高到一定程度后,液化产物的残渣率和重均分子量及LWPF树脂所制胶合板的木破率变化不明显。[结论]对速生桉树木材的液化工艺及其液化产物的树脂化合成工艺进行了优化。[Objective] The research aimed to supply reference for liquification of lumber of fast-growing eucalyptus and its products application.[Method] With sulphuric acid as catalyst and phenol as liquefier,the eucalyptus lumber of fast-growing man-made forest was liquified and the liquified products and formaldehyde were used for resinification reaction to produce liquified wood-base phenol formaldehyde（LWPF）,the influence of liquor-to-wood ratio on liquification efficiency,weight-average molecular weight of liquified products and gluing performance of LWPF resin was researched.[Result] As the liquor-to-wood ratio was increased,the residue rate and weight-average molecular weight of liquified products were decreased and the wood failure ratio of plywood produced from LWPF resin was increased.When the liquor-to-wood ratio was increased to some degree,the residue rate and weight-average molecular weight of liquified products and the lumber-crushed rate of plywood produced from LWPF resin changed little.[Conclusion] The liquification technology of lumber of fast-growing eucalyptus and the resinification synthesis technology of its liquid products were optimized in this research.
