Abstract

Un procedimiento para preparar un adhesivo para madera compuesto de 2 a 8 moles de formaldehido, 1 a 1,6 moles de melamina y 1,7 a 3,3 moles de urea por cada mol de fenol, comprendiendo el procedimiento las etapas de condensar en un reactor fenol y formaldehido, añadir subsiguientemente melamina al condesado fenol-formaldehido en el reactor y continuar la condensación de la melamina a un pH de 8,5 a 9,5 y a una temperatura de 85 a 100ºC hasta que el contenido del reactor se vuelve transparente, y añadir 1,7 a 3,3 moles de urea al reactor y condensarla con el condensado fenol- formaldehido-formaldehido-melamina hasta que se alcanza una tolerancia el agua de 70 a 180%.
