| description | Provided is a wood fiber board, and a production method thereof, such that the wood fiber board contains no phenolic resin, is simple to produce, and exhibits flexural strength and water 5 resistance comparable to those of wood fiber boards produced by incorporating a phenolic resin. The wood fiber board of the present invention has only wood fibers; a polyacrylamide resin being an amphoteric-ionic resin, which 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 which has a molecular weight ranging from 800,000 to 3,000,000; and cationic paraffin. A method of producing a wood fiber board of the present invention involves preparing a slurry to a solids concentration ranging from 2 to 3 wt% and pH of 3 to 5, and adding only the polyacrylamide resin and paraffin to the slurry. |
