1. A composite material comprising:

  • (a) at least one cellulose- or lignocellulose-containing material; and

    (b) at least one aminoalkylsilane of the general formula (I);


    R1R2N(CHR4)aSi(R3)r(OR)3-r



    (I),wherein groups R1 and R2 are identical or different and in each case are H or a linear, branched or cyclic C1- to C20-alkyl group or an aryl group or an aminocarbyl group, it being possible for groups R1 and R2 to be optionally substituted, groups R4 are identical or different and R4 is H or methyl, a is from 1 to 10, R3 is H or a linear or branched C1- to C8-alkyl group, groups R are identical or different and R is H or a linear or branched C1- to C8-alkyl group and r is 0 or 1 or 2,orat least one cocondensate of at least one aminoalkylsilane of the general formula (I) and at least one further functional silane of the general formula (II);


    R7(CHR6)bSi(R5)p(OR)3-p



    (II),wherein R7 is H or a vinyl group or an amino group or a glycidyloxy group or an acryloyloxy group or a methacryloyloxy group or a mercapto group or a sulfane group or a linear or branched C1- to C20-alkyl group or an aryl group, it being possible for the group R7 to be optionally substituted, groups R6 are identical or different and R6 is H or methyl, b is from 0 to 18, R5 is H or a linear or branched C1- to C8-alkyl group, groups R are identical or different and R is H or a linear or branched C1- to C8-alkyl group and p is 0 or 1 or 2, it being possible for the amino functions in the cocondensate to be partly or completely neutralized with an inorganic or organic acid,oran aqueous solution comprising at least one aminoalkylsilane of the general formula (I) or at least one cocondensate based on at least one aminoalkylsilane of the general formula (I) and at least one further functional silane of the general formula (II), as a binder.
