Abstract

The disclosure relates to a method for producing a wood-based material panel with the steps: producing a raw wood-based material panel which includes a first lateral surface and a second lateral surface that runs parallel to the first lateral surface, and edge surfaces that connect the lateral surfaces to each other; applying a liquid containing a flame retardant at least to the first lateral surface; and applying a negative pressure to the second lateral surface so that the liquid containing the flame retardant is sucked into a peripheral zone of the raw wood-based material panel, and/or applying an overpressure to the first lateral surface so that the liquid containing the flame retardant is pressed into a peripheral zone of the raw wood-based material panel, resulting in the wood-based material panel.
