Year	Description
2002	Invention patented by Man-Gu Sim on April 22th, 2002. Abstract: 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 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 manufacturing 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.about.65:40.about.10:10.about.20:10.about.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.about.300.degree. 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.
