Abstract
PURPOSE: To readily cure a furan resin for use as a self-curing mold binder at a temperature below room temperature, by employing as an acid curing catalyst, a phosphoric acid-containing solid material prepared by supporting phosphoric acid on a carrier such as silicon oxide or a siliceous material.
CONSTITUTION: A substantially water-free, solid, acid curing catalyst containing about 30W60wt% of phosphoric acid (calculated as P2O5) is prepared by providing as a carrier such as silicon oxide or a siliceous materials, such as white carbon or activated clay having the form of fine particles and a great specific surface area; impregnating the carrier with a phosphoric acid solution having a concentration of about 75W85%; and drying the impregnated carrier at a carrier temperature not exceeding about 250°C. Said curing catalyst is added to a furan resin (usually, about 1W3pts.wt. of the resin is added to 100pts.wt. of molding sand) in an amount of about 5W50wt%, pref. 8W30wt% (calculated as P2O5). The curing catalyst is used to cure the furan resin and form high compressive strength molds.
