Abstract: PURPOSE:To obtain a high strength mold by further using alkyl silicate or silicone oil as component of binder at the time of using silane coupling agent and water soluble phenol resin as the binder and adding curing agent to make refractory granular material. CONSTITUTION:The sand mold for casting, which is shaped with the refractory granular material by using the silane coupling agent and the water soluble phenol resin as the binder and organic ester as the curing agent, is obtd. As the component of binder, further the alkil silicate having alkil group with 1 - 8 number of carbons or this low condensate or denaturated or non-denaturated silicone oil is used. As the alkil silicate, methyl silicate, ethyl silicate, etc., and as silicone oil, dimethyl siloxane, silicon fluorination, etc., are used. By this method, as the high strength mold is obtd. and consumption of the binder is reduced and recovery of the molding sand is made to easy and gas generated quantity is reduced, the development of gas defect is restrained and the sound casting can be obtd.
