Abstract

PURPOSE: To obtain the fast-curing type mold of easy regeneration without any limit of pot life and selectivity of sand by using the mixture in a wet state of sand for mold 100 parts and water-base thermosetting type phenolic resin 1W20 parts.
CONSTITUTION: So-called resol type phenolic resin reacted by alkaline catalyst with the molar ratio of formaldehyde to phenol being made 1 or more is dissolved or dispersed in water or the mixed solution composed primarily of water. If necessary, alkali material such as caustic soda is added to this to make its pH8 or more. Sand for mold such as silica sand is mixed to this at the foregoing ratio and if necessary, alkali material is added to make its pH8 or more. Even more, this is maintained in a wet state. The degree of wetting is controlled by increase or decrease of water, etc., addition of water at the sand mixing, etc. because it varies with mold making methods. After the mold is made by this resin coated sand grains, it is heat set at 200°C or more, whereby the mold is obtained.
