Abstract: Procedimiento para la fabricación de un material derivado de la madera, que presenta, al menos, una chapa de forro pegada en forma de hoja con un soporte o con otras chapas de forro, que comprende: i) la impregnación de, al menos, un forro, que presenta un espesor comprendido entre 20 µm y 10 mm, con una composición endurecible acuosa, que contiene a) al menos un compuesto de urea reticulable, elegido entre los compuestos de urea H, que presentan al menos un grupo enlazado con N, de la fórmula CH2OR, en la que R significa hidrógeno o alquilo con 1 hasta 4 átomos de carbono, y/o precondensados del compuesto de la urea H, que presentan un grupo 1,2-bishidroxietano-1,2-diilo, que puentea a los dos átomos de nitrógeno de la urea, y productos de la reacción o mezclas del compuesto de urea H con, al menos, un alcohol, que se elige entre los alcanoles con 1 hasta 6 átomos de carbono, los polioles con 2 hasta 6 átomos de carbono y los oligoetilenglicoles, y b) al menos un catalizador K, que provoca la reticulación del compuesto de urea; ii) el encolado del forro impregnado y/o del soporte con una composición encolante y iii) la elaboración del forro encolado para dar un material derivado de la madera a temperatura elevada con endurecimiento del compuesto de urea endurecible, estando presente el compuesto endurecible de la urea durante el encolado en la etapa ii) en el forro impregnado en una forma ampliamente exenta de reticulación.

Abstract: Sulfonic acid group copolymer composition comprises (a) 30-95 mole% of at least one monoethylenically unsaturated carboxylic acid, (b) 3-35 mole% of at least one sulfonic acid group containing monomers, and (c) 1-35 mole% of nonionic monomer obtained by statistical or block polymerization. Sulfonic acid group copolymer composition comprises: (1) 30-95 mole% of at least one monoethylenically unsaturated carboxylic acid; (2) 3-35 mole% of at least one sulfonic acid group containing monomer of formula (I); and (3) 1-35 mole% of nonionic monomer of formula (II). R = H or Me; R1 = branched 1-4C alkyl; X = chemical bond or -COO-R1; and M = H, alkali metal, or ammonium. R2 = H or Me; R3 = chemical bond or optionally branched 1-6C alkylene; R4 = optionally branched 2-4C alkylene; R5 = optionally branched 1-6C alkyl, 5-8C cycloalkyl, or aryl; n = 3-50. The polymer is obtained by statistical or block polymerization.

Abstract: The invention relates to a lignocellulose material comprising a crosslinkable nitrogen compound, technically a formaldehyde condensate, in crosslinked form in a constituent amount (N) of at least 1% by weight, calculated as nitrogen and based on the total weight of the lignocellulose material, in which the ratio (FA/N) of formaldehyde emission (FA), determined by means of the bottle method according to EN 717, part 3, to constituent amount of the nitrogen compound (N) exhibits a value of at most 5.0×10−3, and to a process for the preparation thereof.

Abstract: The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method.
