Abstract

PURPOSE: To prepare phenol resin having specified characters and suitable for resin binder which does not need curing agent by reacting phenols with aldehydes in two steps in the presence of at least two kinds of catalysts whose functions and effects are different.
CONSTITUTION: The first-step reaction of phenols such as phenol or p-cresol with aldehydes such as formalin or polyoxymethylene in the presence of a primary catalyst such as ammonia or nitrogen-containing compounds gives the first condensation products having methylene and nitrogen bonds in a phenol nucleus which constitute basic structures of the resin. Second reaction which is carried out in the presence of a different catalyst such as oxide or hydroxide of alkali metal or alkaline earth metal gives a solid resol type phenol resin whose index of nitrogen bond is 0.6W0.9, index methylene bond is 0.18W0.25, index of methylol group is 0.4W0.7, softening point is 75W90°C, gelation time is 40W120 seconds and MW is 300W450.
