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: A process for the production of OSB wood-based panels including: a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and, optionally, gluing the non-steam treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board. The steam treatment takes place after the wood strands have been produced and made available, or after the wood strands have been sifted and separated according to the use of the wood strands for the middle and top layers of the panel. Also, an OSB wood-based panel made using the process.

Abstract: Disclosed is a process for the treatment of wood strands suitable for the manufacture of OSB boards, in which the wood strands are treated with steam without drying after extraction, the steam being passed over the wood strands at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar. Also disclosed is a process for the production of OSB wood-based boards including the steps of a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and gluing the non-steam-treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board.

Abstract: A method for producing wood material boards with reduced emission of volatile organic compounds (VOCs), including: a) producing woodchips from suitable timbers; b) heat-treating at least one portion of the woodchips at a temperature between 150° C. and 300° C. for a period of 1 to 5 hours; c) crushing the wood chips that are not heat-treated and at least one portion of the heat-treated woodchips by machining in order to obtain wood shavings or by solubilizing in order to obtain wood fibers; d) gluing the wood shavings or wood fibers with at least one binding agent; e) applying the glued wood shavings onto a transport belt while forming a multi-layered shavings cake or applying the glued wood fibers onto a transport belt while forming a single-layer fiber cake; and f) compressing the shavings cake or the fiber cake to form a wood material board.

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.

Abstract: The invention relates to a method for producing OSB wood material panels, in particular OSB wood material panels having reduced emission of volatile organic compounds (VOCs), including the following steps: a) producing wood strands from suitable woods; b) torrefying at least some of the wood strands; c) glue-coating the torrefied wood strands and non-torrefied wood strands with at least one binder; d) scattering the glue-coated wood strands onto a conveyor belt; and e) pressing the glue-coated wood strands to form a wood material panel. The invention further relates to an OSB wood material panel that can be produced in accordance with said method and to the use of torrefied wood strands to reduce the emission of VOCs from OSB wood material panels.
