Title
(DE) HERSTELLUNG VON AMINOPLASTHARZEN MITTELS EXTRUDER
(EN) EXTRUDER PRODUCTION OF AMINO RESINS
(FR) FABRICATION DE RÉSINES AMINOPLASTES AU MOYEN D'UNE EXTRUDEUSE
Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung eines aminoplastisch gebundenen Holzwerkstoffs, umfassend a. das Bereitstellen einer Mischung umfassend ein Harnstoff-Formaldehyd-Kondensat, b. die reaktive Extrusion der Mischung umfassend ein Harnstoff-Formaldehyd-Kondensat in einem Extruder, c. die Beleimung von lignocellulohaltigemMaterial durch Aufbringen einer Leimflotte enthaltend oder bestehend aus dem extrudierten Leim auf das lignocellulosehaltige Material, wobei das Aufbringen mittels einer Leimapplikationseinrichtung erfolgt, und dem Verpressen des beleimten lignocellulosehaltigen Materials. Außerdem betrifft die Erfindung mit dem erfindungsgemäßen Verfahren hergestellte Holzwerkstoffe und eine Vorrichtung geeignet zur Durchführung des erfindungsgemäßen Verfahrens. Ferner betrifft die Erfindung die Verwendung einer reaktiven Extrusion für aminoplastische Bindemittel zur Herstellung formaldehydemissionsarmer Holzwerkstoffe.
(EN) The invention relates to a process for producing an amino resin-bound wood-based material, comprising a. providing a mixture comprising a urea-formaldehyde condensate, b. reactively extruding the mixture comprising a urea-formaldehyde condensate in an extruder, c. resinating lignocellulosic matter by applying a resin liquor comprising or consisting of the extruded resin to the lignocellulosic matter by means of a resin application device, and compressing the resinated lignocellulosic matter. The invention also relates to wood-based materials produced by the process of the invention and to an apparatus suitable for implementing the process of the invention. The invention additionally relates to the use of reactive extrusion for amino resin binders for producing low-formaldehyde-emission wood-based materials.
(FR) L'invention concerne un procédé de fabrication d'un matériau dérivé du bois à liaison aminoplastique, comprenant a. la préparation d'un mélange comprenant un condensat d'urée-formaldéhyde, b. l'extrusion réactive du mélange comprenant un condensat urée-formaldéhyde dans une extrudeuse, c. l'encollage de matériau lignocellulosique par application d'un bain de colle contenant de la colle extrudée ou constitué de la colle extrudée sur le matériau lignocellulosique, l'application s'effectuant au moyen d'un dispositif d'application de colle, et la compression du matériau lignocellulosique encollé. En outre, l'invention concerne des matériaux dérivés du bois fabriqués au moyen du procédé selon l'invention et un dispositif adapté à la mise en oeuvre du procédé selon l'invention. L'invention concerne en outre l'utilisation d'une extrusion réactive pour des liants aminoplastes pour la fabrication de matériaux dérivés du bois à faible émission de formaldéhyde.
