PURPOSE:To produce a composite product without adding adhesive bonding agent by a method in which finely crushed raw material composed of lignocellulose material containing sugar is formed into a desired mat after it has been dried, and then it is formed under heating and pressurizing. CONSTITUTION:The raw material composed of the lignocellulose material containing sugar (e.g. the bagasse of sugar cane, cone cane and sunflower cane, etc.) is finely crushed, and is divided into particle, fiber, strand and flake. After this finely crushed material has been dried, it is formed into a desired mat. This mat is press-heated under sufficient pressure and in sufficient time to compress the formed product at the temperature equal to or higher than 180 deg.C. The kinds of liberated sugar and saccharid are chemically sophisticated under pressurizing and heating and act as adhering and reinforcing agent. The formed product excellent in strength, dimensional stability and resistance for boiled water and aid hydrolyzing may be obtained without adding other adhesive bonding agent or adhesive. |
