Abstract


In this study, Anticorrosive fir was liquefied in phenol, and the liquefied wood were used to produce adhesive by resinification. The effect of resinification time, resinification temperature, molar ratio (NaOH/liquefied wood) and molar ratio (methanal/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 150 min, resinification temperature of 90°C, molar ratio (NaOH/liquefied wood) of 0.5 and molar ratio (methanal/liquefied wood) of 1.8. Using adhesive produced under the optimal conditions to bond plywood, the bonding strength and formaldehyde emission of plywood produced accorded with related national standard (china), and the plywood produced belonged to calss I.
