Abstract: The invention relates to a binder composition for manufacturing a wood-based material, in particular a board-shaped wood-based material, a method for manufacturing such a wood-based material and such a wood-based material. In order to provide a binder composition and a method for manufacturing such a wood-based material as well as such a wood-based material, in which the speed of curing of isocyanate binders can be specifically controlled and in particular accelerated, whereby the curing temperature can be lowered on the one hand and kept within a predetermined temperature interval on the other hand, so that an onset of curing can be controlled, thereby ensuring a safe, fast and cost-effective manufacture process without a reduction in product quality, it is provided that the binder composition according to the invention for manufacturing a wood-based material has an organic phase comprising at least one isocyanate binder, an aqueous phase and also a solubilizer for rapidly mixing the two phases and/or for accelerating the curing of the isocyanate binder.

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.
