Abstract

PURPOSE: After phenol and formaldehyde in water are subjected to the reaction in the presence of a caustic alkali, the polycondensation reaction is effected to produce a phenolic resin adhesive that is good in operation and adhesion performances and readily of spray coating on wood chips.
CONSTITUTION: An aqueous solution of mixture consisting of 1 mole of phenol, 2,2W2,8, preferably 2.4W2.7 moles of formaldehyde, 0.4W0.8, preferably 0.5W0.8 mole of a caustic alkali is heated to 30W60, preferably to 40W50°C to effect the reaction and then heated to 70W90, preferably 75W85°C to effect the polycondensation reaction. Thus, an adhesive of an aqueous phenolic resin solution of 35W45, preferably 38W42 wt% non-volatile content, 200W400, preferably 220W350 P.S. viscosity, and 10.9W12.5, preferably 11.0W12.0 pH is obtained.
