Title (EN) USE OF LOW MOLECULAR WEIGHT LIGNIN TOGETHER WITH LIGNIN FOR THE PRODUCTION OF A PHENOL - FORMALDEHYDE BINDER COMPOSITION
(FR) UTILISATION DE LIGNINE À FAIBLE POIDS MOLÉCULAIRE AVEC DE LA LIGNINE POUR PRODUIRE UNE COMPOSITION DE LIANT DE PHÉNOL-FORMALDÉHYDE
Abstract:
(EN) The present invention relates to a method for producing a binder composition, wherein the method comprises the following steps: (i) forming an aqueous composition comprising reactant components including lignin molecules of 11 –60 lignin units, lignin molecules of 1–10 lignin units, polymerizable substance and crosslinking agent in the presence of a catalyst; and(ii) cooking the com- position at a temperature of 60–95 °C for polymerizing the reactant components until a binder composition with a predetermined viscosity value is formed.
(FR) La présente invention concerne un procédé de fabrication d'une composition de liant, le procédé comprenant les étapes suivantes : (i) former une composition aqueuse comprenant des composants réactifs comprenant des molécules de lignine de 11-60 unités de lignine, des molécules de lignine de 1-10 unités de lignine, une substance polymérisable et un agent de réticulation en présence d'un catalyseur; et (ii) faire cuire la composition à une température de 60-95°C pour polymériser les composants réactifs jusqu' à ce qu'une composition de liant avec une valeur de viscosité prédéterminée soit formée.
