Hybrid adhesive and its use in wood-derived matter plates

摘要

Hybrid adhesive comprising - at least one polycondensation adhesive in the form of a polyamide condensate adhesive, a polyester condensate adhesive, a silicone condensate adhesive and / or a formaldehyde condensate adhesive, - at least a polyaddition adhesive in the form of an epoxy resin, polycyanurate and / or polyurethane adhesive and - at least one oxidic, hydroxydic or oxyhydroxy nanoparticle less than 500 nm, the at least one particle being modified with at least one compound of formula general (I) RaSiX (4-a) (I), or of general formula (II) ObXc (OH) dReSiO (4-bcde) / 2 (II), in which - 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-hydrolyzable organic moiety R selected from the group comprising substituted and unsubstituted alkyl, substituted and unsubstituted aryl, alq substituted and unsubstituted uenyl, substituted and unsubstituted alkynyl, substituted and unsubstituted cycloalkyl, which may be interrupted by -O- or -NH-, and - in which R has at least one functional group Q that is selected from a group containing an epoxy, hydroxyl, ether, amino, monoalkylamino, dialkylamino, an anilino, amido, carboxyl, alkynyl, acryl, acryloxy, methacryl, methacryloxy, mercapto, cyano, alkoxy, isocyanate, aldehyde, alkylcarbonyl, acid anhydride group and / or substituted and unsubstituted phosphoric acid. - R and X respectively can be the same or different from each other and - is a = 1, 2, 3, in particular 1, - are b, c, d = 0 or 1 and - is e = 1, 2, 3.
