Definitions

  • Aminoplast resins are known in the art and e.g. in "Ullmanns Enzyklopadie der ischen Chemie", 4th Edition, Volume 7, pp 403ff .. Aminoplast resins can be obtained by condensation of an amino, imino or amide group-containing component with a carbonyl compound
  • lignocellulosic material plant material containing lignocellulose, lignocellulose according to the invention containing cellulose and / or hemicellulose and lignin.
  • a composition containing an aminoplast resin and a first hardener is glued by applying a previously prepared mixture of aminoplast resin and first hardener to the wood particles.
  • Aminoplast resin and the first hardener are applied separately to the wood particles.

Abstract

La présente invention concerne un procédé de fabrication de matériaux à base de particules de bois. Ledit procédé comprend les étapes suivantes : a) utilisation d'un premier matériau, contenant de la lignocellulose, sous forme de particules de bois ; b) collage du premier matériau contenant de la lignocellulose avec une composition qui comprend au moins une résine aminoplaste et au moins un premier durcisseur, le premier durcisseur étant obtenu par dissolution hydrothermique et/ou mécanique d'un second matériau contenant de la lignocellulose tandis que le second matériau contenant de la lignocellulose provient d'une autre matière brute que le premier matériau contenant de la lignocellulose ; et c) compresser en un matériau à base de particules de bois. La présente invention concerne en outre un matériau à base de particules de bois qui est obtenu par ce procédé et l'emploi d'un matériau, contenant de la lignocellulose, dissolu de manière hydrothermique et/ou mécanique en tant que durcisseur pour la résine aminoplaste dans un procédé de fabrication d'un matériau à base de particules de bois.
