Abstract

PURPOSE: To manufacture a high strength mold having a good collapsing property and low hygroscopic property at a low price, by hardening the mold formed by adding and mixing carboxylate, Ca(OH)2 or CaO, water and SBR latex with refractory material by CO2 gas.
CONSTITUTION: Mold material is made by adding and mixing carboxylate and SBR latex as main binder of the mold and Ca(OH)2 or CaO and water with refractory material. The mold is formed by filling up the above mold material in the pattern. The mold is hardened by blowing CO2 in the above mold.
