Abstract

A hardenable, mouldable, porous mixture comprises a major proportion of a refractory foundry material, up to 5,5% of a furfuryl alcohol binder, a reaction modifier, and optionally an extender for the binder. The binder is defined as including furfuryl alcohol as such or partially polymerized, polymerizable furfuryl alcohol-containing resins or their mixtures. The reaction modifier polymerizer or condenses the binder without heating and substances specified are sulphuric, phosphoric, hydrochloric, benzene and toluene sulphonic acids, esters of phosphoric acids, chloroethyl phosphoric dichloride and tris b chloroethyl phosphite. Refractories specified are sand, zircon, clay and iron ore, whilst extenders are wood flour and cereals.
