Wood material board with reduced emission of volatile organic compounds (VOCs) and method for the production thereof

A process for producing woodbase panels with reduced emission of volatile organic compounds (VOCs), comprising:

• a) producing wood chips from suitable lumbers,
• b) heat-treating at least a part of the wood chips by heating in an oxygen-depleted or oxygen-free environment at a temperature between 150° C. and 300° C. over a period of 1 h to 5 h;
• c) comminuting the non-heat-treated wood chips and at least a part of the heat-treated wood chips by shaving to give wood shavings or by digesting to give wood fibers;
• d) resinating the wood shavings or wood fibers with at least one binder, wherein the wood shavings or wood fibers have been produced from the heat-treated and the non-heat-treated wood chips according to step (c);
• e) applying the resinated wood shavings to a conveyor belt, to form a multilayer shaving cake, or applying the resinated wood fibers to a conveyor belt, to form a single-layer fiber cake;
• and
• f) compressing the shaving cake or the fiber cake to form a woodbase panel.
