摘要

The invention relates to a method for the production of a modified montan wax, a modified montan wax and use of the same for production of an aqueous montan wax composition. The method for production of a modified montan wax is characterised in that montan wax is firstly melted, then tall resin or an ester made from tall resin is added with stirring, various acid groups are introduced into the molecular skeleton in the presence of mineral acids with an oxidising effect with air injection and stirring and said acid groups are converted into the corresponding salts by addition of alkali hydroxides. A modified montan wax is obtained made from a montan wax mixed with tall resin or an ester made from tall resin, whereby acid groups, provided with acid groups in the molecular skeleton which are converted into the salts thereof. The invention further relates to the use of the modified montan wax for the production of an aqueous montan wax composition with hydrophobic properties.
