Claim Text:
1. A hybrid adhesive, for use in the production of wood-based materials, comprising at least one polycondensation adhesive being a polyamide, a polyester, and/or a formaldehyde condensate adhesive, at least one polyaddition adhesive being polycyanurate, and/or polyurethane adhesive, and at least one oxidic, hydroxidic or oxihydroxidic nanoparticle with a size between 2 and 100 nm, wherein the at least one nanoparticle is a SiO wherein the at least one nanoparticle is modified with at least one compound of the general Formula (I) or the general Formula (II) wherein X is H, OH or a hydrolyzable radical selected from the group consisting of halogen, alkoxy, carboxy, amino, monoalkylamino or dialkylamino, aryloxy, acyloxy, and alkylcarbonyl, wherein R is a non-hydrolyzable organic radical R selected from the group consisting of substituted and non-substituted alkyl, substituted and non-substituted aryl, substituted and non-substituted alkenyl, substituted and non-substituted alkynyl, substituted and non-substituted cycloalkyl, and combination thereof, which can be interrupted by —O—, wherein R includes at least one functional group Q which is selected from the group consisting of epoxy, hydroxy, ether, carboxy, alkynyl, acrylic, acryloxy, methacrylic, methacryloxy, mercapto, cyano, alkoxy, isocyanato, aldehyde, alkylcarbonyl, acid anhydride and phosphoric acid group, and wherein the substituent(s) for the substituted alkyl R are selected from the group consisting of epoxy, hydroxy, ether, carboxy, alkynyl, acrylic, acryloxy, methacrylic, methacryloxy, mercapto, cyano, alkoxy, isocyanato, aldehyde, alkylcarbonyl, acid anhydride, phosphoric acid group, and combinations thereof, R and X each can be the same or different from each other, and a=1, 2, 3, b, c, d=0 or 1, and e=1, 2, 3.
