Abstract
789,308. Mould and core materials. MO OCH DOMSJO AKTIEBOLAG. Oct. 5, 1955 [Oct. 6, 1954], No. 28437/55. Class 83 (1). A mould or core composition comprises sand bound with at least one fatty acid ester in the form of a core-oil, and a water-soluble cellulose derivative. The cellulose derivative is present in an amount 0.1-2 parts by weight to 100 parts of sand, the oil in an amount 0.5-5 parts by weight to 100 parts of sand, and moisture 2-7 parts by weight to 100 parts of sand. Other binders such as synthetic resins, and also extenders for the cellulose derivative, such as wood flour or clay, may also be present. Cellulose-derivatives referred to are water-soluble cellulose ethers such as methyl cellulose, methyl ethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, methyl or ethyl hydroxyethyl cellulose; water-soluble salts of cellulose ether carboxylic acids such as sodium carboxymethyl cellulose, cyanoethyl cellulose, sulphoethyl cellulose; and sodium salts of cellulose sulphuric acid esters.
