The present invention relates to the use of aqueous wax dispersions to impregnate lignocellulose materials. The invention also relates to a method of hydrophobicizing lignocellulose materials, which involves impregnating the lignocellulose material with an aqueous wax dispersion, and to the lignocellulose materials obtainable as a result. The aqueous dispersions of the waxes or wax- like polymers are characterized in that the wax constituent has a melting point above 75°C, preferably above 80°C and in particular above 90°C and the dispersed wax particles have an average size below 500 nm. |
