Abstract
1414538 Urea-glyoxal-formaldehyde/furfuryl alcohol binders for foundry sand KAO SOAP CO Ltd 28 Aug 1973 [30 Aug 1972] 40407/73 Headings C3N and C3R An acid-hardening liquid binder for foundry sand comprises (A) 2À5-55 wt. per cent of a urea-glyoxal-formaldehyde in which there are 2-4 aldehyde groups per molesule of urea, 10-60% of them deriving from the glyoxal, there being no more than 1 mole of glyoxal and 2À5 of formaldehyde per mole of urea; (B) 30- 95 wt. per cent of furfuryl alcohol; and (C) 0-40 wt. per cent of water. Component (A) is obtained by reaction of the three components at pH 4À5-7À5 and 80-160 C. until free formaldehyde falls below 5 wt. per cent; the furfuryl alcohol may be added at any stage. In the Examples urea is condensed with glyoxal and paraformaldehyde in molar ratios 1 : 0À1- 1 : 1À8-2À5 in water at pH 7 and 90 C., then with furfuryl alcohol at pH 6 and 90-100 C., the water being 8-22 wt. per cent and the alcohol 35 wt. per cent of the total. The binder is used with phosphoric acid or p-toluenesulphonic acid catalyst to make foundry sand test pieces.
