Abstract

PURPOSE: To eliminate malodor generation and prevent the collapsing etc. of a mold by allowing to contain a nitrogen-contg. compound, resol type phenol formaldehyde resin and molding sand.
CONSTITUTION: A nitrogen-contg. compound selected from a group consisting of urea, aniline and melamine is added to the methylol phenol obtd. by reacting phenols and formaldehydes in the presence of an alkaline catalyst, and in some cases, further a solvent and preserving agent are added, whereby a methylol-phenol-contg. soln. is once prepd. This soln. is added to molding sand contg. a hardener and these are thoroughly kneaded in a manner as to mix uniformly, whereby the composition is prepd. This self-hardening molding sand composition is molded simply by putting it into a wooden mold and allowing to stand at ordinary temp.
