Abstract (en)

[origin: EP2607032A1] Preparing wood products comprises: (a) providing lignocellulose containing comminution products; (b1) introducing a first additive to the lignocellulose containing comminution products, where the first additive is an amidine compound (I); (b2) introducing a second additive to the lignocellulose-containing comminution products, where the second additive is borate, aluminate and/or phosphate; and (c) optionally compressing the lignocellulose containing comminution products mixed with the additive/additives with an adhesive under heat treatment to form wood material. Preparing wood products comprises: (a) providing lignocellulose containing comminution products; (b1) introducing a first additive to the lignocellulose containing comminution products, where the first additive is an amidine compound of formula (RC(=NH)-NH 2) (I) or optionally its salt; (b2) introducing a second additive to the lignocellulose-containing comminution products, where the second additive is borate, aluminate and/or phosphate; and (c) optionally compressing the lignocellulose containing comminution products mixed with the additive/additives with an adhesive under heat treatment to form wood material, where the addition of the additives can be reduced according to the emission of volatile organic compounds and optionally very volatile organic compounds, preferably acids and terpenes. R : a carbonaceous group or an amine group, Independent claims are included for: (1) a treating agent for reducing the emission of volatile organic compounds and optionally very volatile organic compounds, preferably terpenes and acids from the lignocellulose containing comminution products and wood composites from lignocellulose containing comminution products comprising (I) and at least one borate; and (2) the wood product, preferably a fiber plate, which is a light and super lightweight medium density fiberboard or oriented strand board obtained by the above method.
