Abstract
A process for preparing a wood adhesive composed of 2 to 8 mols formaldehyde, 1 to 1.6 mols melamine and 1.7 to 3.3 mols urea for each mol of phenol, which comprises condensing phenol and formaldehyde in a reactor, subsequently adding melamine to the phenol-formaldehyde condensate in the reactor and continuing the condensation of melamine at a phi of 8.5 to 9.5 and at a temperature of 85 to 100 DEG C until the contents of the reactor become clear, and adding 1.7 to 3.3 mols of urea to the reactor and condensing it with the phenol-formaldehyde- melamine condensate until a water tolerance of 70 to 180% is reached.
