Patent ID: 8039110

Claim:
A composite material, comprising: (a) at least one cellulose- or lignocellulose-containing material; and (b) a binder, comprising: (1) at least one aminoalkylsilane of formula (I): R 1 R 2 N(CHR 4 ) a Si(R 3 ) r (OR) 3-r (1), wherein groups R 1 and R 2 are identical or different, optionally substituted, and in each case are H or a linear, branched or cyclic C 1 - to C 20 -alkyl group or an aryl group or an aminocarbyl group; groups R 4 are identical or different and R 4 is methyl; a is from 1 to 10; R 3 is H or a linear or branched C 1 - to C 8 -alkyl group; groups R are identical or different and R is H or a linear or branched C 1 - to C 8 -alkyl group; and r is 0 or 1 or 2; or (2) at least one cocondensate of the at least one aminoalkylsilane of formula (I) and at least one functional silane of formula (II): R 7 (CHR 6 ) b Si(R 5 ) p (OR) 3-p (II), wherein R 7 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 C 1 - to C 20 -alkyl group or an aryl group, and wherein R 7 is optionally substituted; groups R 6 are identical or different and R 6 is H or methyl; b is from 0 to 18; R 5 is H or a linear or branched C 1 - to C 8 -alkyl group; groups R are identical or different and R is H or a linear or branched C 1 - to C 8 -alkyl group; and p is 0 or 1 or 2; wherein the amino functions in the cocondensate are optionally partly or completely neutralized with an inorganic or organic acid; or (3) an aqueous solution comprising the at least one aminoalkylsilane of formula (I) or at least one cocondensate of the at least one aminoalkylsilane of formula (I) and the at least one functional silane of formula (II).
