Abstract
L'invention concerne un procédé de production de produits composites reconstitués dimensionnellement stables, à partir d'un matériau lignocellulosique. En traitant de la lignocellulose à la vapeur à haute pression pour décomposer et hydrolyser les fractions hémicellulose, cellulose et lignine de la lignocellulose, et en utilisant ces produits de décomposition à la fois comme agent de liaison et agent gonflant, on tranforme, par voie thermique et sous pression, dans une opération de moulage, la lignocellulose traitée en produits composites moulés, tels que des panneaux ou des articles moulés. Les produits composites ainsi obtenus possèdent de bonnes propriétés physiques et mécaniques. Plus particulièrement, en ce qui concerne le gonflement en épaisseur et l'allongement linéaire des panneaux (cartons durs et agglomérés, par exemple), la stabilité dimensionnelle peut être réduite à des niveaux minimaux lorsque les panneaux fabriqués ont une forte densité. L'adhésif obtenu par thermodurcissement des produits de décomposition de l'hémicellulose, de la cellulose et de la lignine est fort et stable, résiste à l'eau bouillante et à l'hydrolyse par voie acide, et est exempt d'émanations de formaldéhyde. Ainsi, les panneaux et produits moulés reconstitués de l'invention conviennent pour des applications à l'extérieur, et en particulier pour des applications à l'intérieur. L'absence d'émanations de formaldéhyde rend le produit très approprié pour des applications à l'intérieur. Les coûts de production des produits reconstitués sont considérablement plus bas par comparaison avec le procédé classique, du fait de la non utilisation de résine synthétique, chère.
