摘要:
A composition and method for producing a fiberboard. The fiberboard is produced from a mixture of wood-containing material, a binder, a waterproofing agent and a liquid concentrate. The liquid concentrate contains boric acid or a derivative thereof, a water soluble compound which includes an alcohol and a water soluble amine-containing compound, and optionally water. The mixture is intermixed and subsequently pressed at a predetermined compacting pressure and a predetermined temperature.
