CA 2452410

There is disclosed a board and a board composition using clay and crushed vegetational materials, which is environment friendly and recirculative and can be also be used as a natural basic material for articles of furniture or architectural interior/exterior materials, thereby being used as compost when being scrapped, and a manufactuing method thereof. The board is fabricated by forming a composition fabricated by mixing vegetational material, clay, a seaweed adhesive and a functional adhesive, and an auxiliary material at a ratio of 40-65:40-10:10.20:10-5 weight percent, and then throwing the composition into a hopper; withdrawing the composition received in the hopper so as to be passed between a pair of rollers and then molding the composition in a desired size; passing the composition between the rollers heated at a temperature of 100-300~C and disposing paper or woven fabrics at upper and lower surface of the composition and then pressing the composition along with the paper or woven fabrics; and cutting the pressed composition in a desired size.

L'invention concerne un panneau et une composition de panneau, utilisant de l'argile et des matériaux végétaux broyés, respectueux de l'environnement et utilisant le recyclage, qui peut être utilisé comme matériau de base pour des articles de mobilier ou des matériaux d'architecture intérieure/extérieure, et qui sert de compost lorsqu'il est mis au rebut. L'invention concerne aussi un procédé de fabrication consistant à former une composition obtenue par mélange de matériau végétal, d'argile, d'un adhésif à base d'algue, d'un adhésif fonctionnel, et d'un matériau auxiliaire, dans les rapports en pour cent en poids de 40.sim.65:40.sim.10:10.sim.20:10.sim.5, puis à verser ces matériaux dans une trémie, à faire passer la composition sortant de la trémie entre deux rouleaux, à mouler la composition selon la taille recherchée, le passage entre les rouleaux étant effectué à une température comprise entre 100 et 300 ·C, à déposer du papier ou un textile sur les surfaces inférieure et supérieure de la composition, puis à presser la composition avec le papier ou le tissu et à découper la composition pressée selon la taille recherchée.
