The invention relates to a binder for producing materials based on wood chips and/or wood fibers. The aim of the invention is to design a binder which is used for producing and gluing materials based on wood chips and/or wood fibers, contains natural protein components, significantly reduces or even eliminates the drawbacks of the prior art, and can be economically produced and used. Said aim is achieved by a binder which is used for materials based on wood chips and/or wood fibers, comprises an aldehyde-based condensation resin and other additives, and is characterized in that the binder comprises a water-soluble reactive additive containing a peptide/amino acid mixture without moieties of water- insoluble and high-viscosity proteins. The invention also relates to a method for producing said binder as well as a molded article.
L'invention concerne un liant destiné à la fabrication de matériaux à base de copeaux et/ou de fibres de bois. L'invention vise à créer un liant destiné à la fabrication et au collage de matériaux à base de copeaux et/ou de fibres de bois, ce liant contenant des composants protéiques naturels, réduisant notablement voire supprimant les inconvénients de la technique actuelle et présentant un mode de fabrication et d'utilisation économiquement rentables. A cet effet, le liant pour matériaux à base de copeaux et/ou de fibres de bois selon l'invention comporte une résine de condensation à base d'un aldéhyde et d'autres additifs. Le liant est caractérisé en ce qu'il comprend un additif réactif hydrosoluble qui contient un mélange de peptide et d'acide aminé sans protéines à viscosité élevée et insolubles dans l'eau. L'invention porte également sur un procédé de fabrication de ce liant et sur un élément moulé.
