A process for manufacturing a unique fire retardant particleboard includes the supersaturation of wood chips, followed by spraying of the wood chips with an aqueous solution of borate and sulfuric acid, after which the sprayed wood chips are allowed to stand for a period of time to become impregnated and saturated with the aqueous solution. The impregnated wood chips are then allowed to dry, after which a urea formaldehyde adhesive is applied to the wood chips, and the chips are consolidated to form the fire resistant wood particleboard. |
