Abstract
PURPOSE:To enable collapse only by a mechanical impact without requiring a heating treatment after casting by mixing tannin at a specific ratio with a phenol resin and mixing phosphate at a specific ratio therewith. CONSTITUTION:This resin binder for a shell mold is prepd. by co-condensating, melting or mixing 5-50pts.wt tannin with 100pts.wt. phenol resin and mixing 2-50pts.wt. phosphate with the mixture. A novolak type phenol resin, resol type phenol resin, the mixture composed thereof and the melt thereof are usable as the phenol resin. The collapsing property after casting is thereby improved and the need for making the heating treatment after casting is eliminated. The collapsing only by mechanical impact is enabled.
