METHOD FOR PRODUCTION OF AMINO-ALDEHYDE RESINS Russian patent published in 1995 - IPC

Abstract RU 2045540 C1

FIELD: production of wood-particle boards, furniture components, synthetic veneer, and paper-resin films for lamination. SUBSTANCE: method for production of aminoaldehyde resins includes condensation of amine and aldehyde in the presence of complexone 1-hydroxy- ethylidenediphosphonic acid of formula C2H8O7P2 and/or 2-hydroxy- trimethylenedinitriletetraphosphonic acid of formula C7H22N2O13P4. Complexone in the capacity of catalyst is used in amount of 0.05-2.0% in terms of dry matter. Introduced additionally in ready resin may be same complexones in the amount of 0.5- 2.5 mas.p. EFFECT: higher efficiency. 4 cl, 2 tbl
