| titleOfInvention | Method for producing wood-base materials |
| abstract | The invention relates to a method for producing wood-based materials comprising at least one flat thin veneer layer glued with a support or other veneer layers consisting i) in impregnating a veneer with an aqueous hardenable composition which a) comprises at least one type of cross-linkable urea compound selected from urea compounds H containing at least one N-bonded group of formula CH<SUB>2</SUB>OR, wherein R is hydrogen or C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, and/or a 1,2-bishydroxyethane-1,2-diyl group containing two urea nitrogen atoms, urea compound H precondensates and reaction products or mixtures of the urea compound H with at least one type of alcohol selected from C<SUB>1</SUB>C<SUB>6</SUB>-alkanols, C<SUB>2</SUB>-C<SUB>6</SUB>-polyols and oligo ethylene glycols and b) at least one type of catalyst K producing urea compound cross-linking, ii) in gluing the impregnated veneer with an adhesive composition and iii) in transforming the glued veneer into a wood-based material at a high temperature, along with hardening a cross-linkable urea compound, wherein the veneer impregnated prior to gluing at a stage ii) comprises a substantially uncross-linked cross-linkable urea compound. |
