In this paper, Anticorrosive fir was liquefied in phenol, and the liquefied wood was used to produce adhesive by resinification. The effect of resinification time, resinification temperature, mr(NaOH/P)(molar ratio of NaoH/liquefied wood) and mr(F/P)(molar ratio of formaldehyde/liquefied wood) on resinification was investigated by orthogonal experiments in term of the viscosity, solid content and pH of resinification product. Adhesive produced by resinification was then used for plywood production, and plywood strength was detected to assess adhesive. According to experiment results, the optimal conditions of resimification are as follow: resinification time of 140 min, resinification temperature of 90 degrees C, mr(NaOH/P) of 0.5 and mr(F/P) of 2.2.
