The invention relates to a lignocellulosic material which contains a cross- linkable nitrogen compound which is technically a formaldehyde condensate, in cross-linked form in an amount (N) of at least 1 wt.- %, which is calculated as nitrogen and in relation to the total weight of the lignocellulosic material. The quotient (FA/N) of formaldehyde emissions (FA), determined by means of the bottle method according to EN 717 part 3, and the amount of the nitrogen compound (N) has a value of a maximum 5,0 x 10-3. The invention also relates to a method for the production thereof.
La présente invention concerne une matière à base de lignocellulose contenant un composé azoté réticulable qui est techniquement un condensat de formaldéhyde, sous forme réticulée, dans une quantité (N) d'au moins 1 % en poids, calculé en tant qu'azote et par rapport au poids total de la matière à base de lignocellulose. Le rapport (FA/N) de l'émission de formaldéhyde (FA), déterminée au moyen de la méthode au bocal selon EN 717 partie 3, sur la quantité du composé azoté (N) est inférieur ou égal à 5,0 x 10-3. Cette invention concerne également un procédé pour produire ladite matière.
