Abstract
The present invention relates to a method for the production of wood material made of fragmentation products containing lignocelluloses, wherein these wood materials have a reduced emission of volatile organic compounds, aldehydes, particularly formaldehyde. Specifically, the invention relates to methods for the production of wood materials having reduced emission of volatile organic compounds and aldehydes, wherein a certain combination of compounds is utilized in order to prevent the emission of volatile organic compounds and aldehydes, particularly formaldehydes, from the produced wood material. The present invention further relates to wood material that can be produced according this method, particularly OSB panels, particle board, and MDF panels. Finally, the present invention provides compositions suitable in the treatment of wood material to reduce the emission of aldehydes, particularly formaldehyde and volatile organic compounds.
