Title (EN) RESIN COMPOSITION AND BOARD MADE BY USING THE SAME
(FR) COMPOSITION DE RESINE ET PANNEAU REALISE AVEC CETTE RESINE
Abstract:
(EN) A resin composition excellent in strength performance and water resistance due to the use of a lignin; and a board excellent in strength performance and water resistance due to the use of the resin composition. The resin composition is one which is obtained by reacting a lignin with a phenol and an aldehyde, and in which at least 30 wt.% of the nonvolatile matter is accounted for by ingredients derived from a gramineous lignin. The resin composition is added to a lignocellulosic substance in an amount of 0.2 to 30 wt.% on a dry basis based on the lignocellulosic substance, and the mixture is heated and pressed to obtain a board.
(FR) Composition de résine présentant une excellente résistance à la contrainte et une excellente résistance à l'eau grâce à l'utilisation d'une lignine, et panneau formé de cette composition de résine et présentant par conséquent ces mêmes qualités de résistance à la contrainte et à l'eau. La composition de résine est obtenue par mise en réaction d'une lignine avec un phénol et un aldéhyde, au moins 30 % en poids de la matière non volatile étant formés d'ingrédients dérivés d'une lignine de graminée. La composition de résine est ajoutée à une substance de lignocellulose à raison de 0,2 à 30 % en poids de la matière lignocellulosique mesurée à sec, et ce mélange est chauffé et comprimé pour produire un panneau.
