Abstract

1,260,439. Foundry mould compositions. FOSECO INTERNATIONAL Ltd. 31 Dec., 1969, No. 63536/69. Addition to 1,150,541. Heading C3N. A process for the production of a bonded particulate material comprises forming a mixture of the said particulate material with aqueous alkali metal silicate and a mixture of glycerol diacetate (diacetin) and glycerol triacetate (triacetin) and allowing it to harden in the said shape. The particulate material may be sand whilst the alkali metal silicate is preferably sodium silicate in which the molar ratio of SiO 2 to Na 2 O is 2 to 3À3 : 1. It is preferred to employ a mixture of diacetin and triacetin comprising 1-10 parts, more preferably 2-2À5 parts, by weight of triacetin per part by weight of diacetin. The mixture of diacetin and triacetin is preferably present in the range 0À1 to 1% by weight and most preferably 0À2 to 0À5% by weight of the composition. The composition employed in the process may also contain silicon, dicalcium silicate or anhydride, of which dicalcium silicate is a preferred additive. Foundry cores or moulds may be made by this process.
