The present invention relates to the use of modified nanoparticles in wood based panels, in particualr OSB-panels for reduction of the emission of volatile organic compounds (VOCs), the nanoparticles being modified with at least one compound of the general formula (I) R a SiX(4-a) where X is H, OH or a hydrolysable moiety selected from the group comprising halogen, alkoxy, carboxyl, amino, monoalkylamino or dialkylamino, aryloxy, acyloxy, alkylcarbonyl, R is a non-hydrolysable organic moiety R selected from the group comprising substituted and unsubstituted alkyl, substituted and unsubstituted aryl, substituted and unsubstituted alkenyl, substituted and unsubstituted alkinyl, substituted and unsubstituted cycloalkyl, substituted and unsubstituted cycloalkenyl, which may be interrupted by -O- or -NH-, and where R has at least one functional group Q selected from a group comprising an epoxide, hydroxyl, ether, amino, monoalkylamino, dialkylamino, substituted and unsubstituted aniline, amide, carboxyl, alkynyl, acryloyl, acryloyloxy, methacryloyl, methacryloyloxy, mercapto, cyano, alkoxy, isocyanate, aldehyde, alkylcarbonyl, acid anhydride and/or phosphoric acid group, and a = 1, 2, 3, in particular 1 or 2. The invention further relates to a wood based panel containing the modified particles and to a method for producing such a wood based panel. |
