The invention relates to a process for the preparation of solvent-free sulfonamide-type paraffin-based protective compositions having improved properties. First, paraffin is dissolved and sulfonated with an OEl content of 2 to 20% and a rotational solidification point of 40 to 80C in an apolar agent, then the sulfonic acid content is mixed with a mixture of acid amide-polyamine type compounds having a base equivalent of 300 to 700 mg KOH / g plus addition of max. 10% H2O neutralized to a p H value of 8 to 9 and then freed from the solvent and water content. The desired consistency is set in a known manner. Further, bactericides, fungicides and dyes may be added. solvent-free protective compositions; Sulfonamide type; Paraffin base; Paraffin; sulfonic acid content; fungicides; bactericides; dyes} |
