Process for the manufacture of a board of wood-derived matter, in particular in the form of a wood-plastic composite material (WPC), comprising the steps: - application of a mixture of wood fibers with a fiber moisture of wood of between 6 and 15%, with respect to the total weight of the wood fibers, and plastic, in particular of a plastic functionalized with at least one organic compound, with a mixing ratio of between 70% by weight of wood fibers / 30% by weight of plastic and 40% by weight of wood fibers / 60% by weight of plastic, on a first conveyor belt forming a precursor nonwoven material and introduction of the precursor nonwoven material into at least one first tempering furnace for prior compaction; - distribution of at least one non-stick agent without solvent on at least one surface of the previously compacted nonwoven material; - transfer of the previously compacted non-woven material on which non-stick agent has been distributed to at least one double belt press for subsequent compaction until a board of material derived from the wood is given; and - cooling the material board derived from compacted wood in at least one refrigeration press at temperatures between 10 and 70 ° C. |
