Abstract
1279979 Self-hardening foundry mould compositions TSENTRALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT TEKHNOLOGII MASHINOSTROENIA 20 Jan 1970 [20 Jan 1969] 3112/69 Heading C3N A liquid self-hardenable mixture for making foundry cores and moulds comprises:-(a) a filler; (b) sodium silicate; (c) dicalcium silicate; (d) an anionic or non-ionic surface-active agent; (e) aqueous liquor obtained in the production of furanic resins; and (f) water. The aqueous liquor obtained as a by-product in the production of furanic resins contains furfuryl alcohol, phenol, formaldehyde, levulinic acid, methyl alcohol, maleic acid and salts thereof. The liquor is preferably present in an amount 0À3- 1-0 parts by weight. The filler is preferably quartz sand; the sodium silicate preferably has a specific gravity of 1À48 and a SiO 2 : Na 2 O molar ratio of 2À7 : 1; and the dicalcium silicate takes the form of self-crumbling slag from ferrochrome production. The anionic foaming agent may be an alkyl aryl sulphonate, alkyl sulphonate or alkyl sulphate whilst the nonionic foaming agent may be an oxy-ethylated alkyl phenol, alcohol, fatty acid, fatty amine, alkyl naphthol or mercaptan.
