Preparation of Phenolic Adhesive from Liquefied Wood

Formaldehyde-type adhesive was prepared from liquefied wood. The effects of the liquefaction and resinification conditions on the adhesive properties were investigated. The Liquefaction of wood catalyzed with 5% of phenol sulfonic acid at 150˚c for 30 minutes can be considered as a very appropnate condition for the preparation of adhesive. And the resinification of liquefied wood at 90˚c for 30 minutes was good for the preparation of adhesive. The adhesive strength(tensile shear strength after cyclic boil test) of the resinified liquefied(phenolated) wood met Korean Standard of commercial phenol-formaldehyde adhesive for plywood(KS M3702). However, the the storage life at 60 t and th ε viscosity of prepared adhesive were below standard.
