Abstract (en)

[origin: CA3007578A1] The present invention relates to a method for producing wood material boards, in particular chipboards and fibreboards, with reduced emission of volatile organic compounds (VOCs), comprising the steps: 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 solubilising in order to obtain wood fibres; d) glueing the wood shavings or wood fibres 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 fibres onto a transport belt while forming a single-layer fibre cake; and f) compressing the shavings cake or the fibre cake to form a wood material board. The present invention also relates to a chipboard and a fibreboard produced with said method.
