| description | PROBLEM TO BE SOLVED: To provide a wood fiber board which contains no phenolic resin, is manufactured in a simple manner and exhibits bending strength and water resistance comparable to those of wood fiber boards manufactured by including phenolic resin, and a method of manufacturing the wood fiber board.SOLUTION: The wood fiber board comprises only: wood fibers; polyacrylamide resin which is amphoteric-ionic resin, has monomers having cationic groups and monomers having anionic groups at a ratio of 7:3 to 3:7 on a mole ratio basis, and has 800,000-3,000,000 of a molecular weight; and cationic paraffin. The method of manufacturing the wood fiber board involves preparing slurry to achieve 2-3 mass% of a solid content concentration and 3-5 of pH and adding only the polyacrylamide resin and paraffin to the slurry. |
