| 摘要 |
<p>This invention relates to a process for converting lignocellulosic material into a thermosetting, waterproof adhesive and composite products. The lignocellulosic material is first treated with high pressure steam to cause a thermal decomposition and hydrolyzation of hemicellulose to generate water soluble, low molecular weight carbohydrates and other decomposition products. The lignocellulose residue is treated again with high pressure steam to cause a decomposition and hydrolyzation of cellulose to generate water soluble, low molecular weight carbohydrates and other decomposition products. These water solubles can be used alone or in admixture as a thermosetting resin adhesive to create a waterproof bond under heat and pressure. The thermosetting adhesive may also be used for bonding other components of the lignocellulosic material, or in combination with other lignocellulosic material or non lignocellulosic material to produce waterproof composite products.</p> |
