Abstract:
1. A water-soluble concentrate for aqueous functional fluids containing a lubricant selected from the group consisting of animal oil, vegetable oil, mineral oil, and/of synthetic oils, fats, oil components and fat components; fatty alcohols; biocides; fungicides; complexing agents; heavy metal inhibitors; non-ionic or anionic emulsifiers; dispersants; anti-foaming agents; corrosion protectant; and water; characterized in that it contains as the corrosion protectant 2 to 20 weight relative to the weight of the concentrate of a corrosion protectant comprising 5 to 80 weight % of at least one fatty acid alkanolamide based on saturated or unsaturated fatty acids with 10 to 20 carbon atoms, 5 to 80 weight % of at least one alcohol with 2 to 14 carbon atoms selected from the group consisting of isopropanol, n-butanol, butyl diglycol, hexylene glycol, butyl triglycol, and phenoxyethanol, and 5 to 80 weight % of at least one aromatic monocarboxylic acid or aliphatic dicarboxylic acid with 10 to 12 carbon atoms selected from the group consisting of sebacic acid, undecanedioic acid, dodecanedioic acid, and p-tert-butylbenzoic acid, where the sum of these components is 100 weight %, and the weight % is relative to the weight of the corrosion protectant.
