摘要

Aqueous preparation, with surface activity and that protects against corrosion, which contains, in addition to water, i) a corrosion protection system (I) that comprises a) aliphatic carboxylic acids with at least 6, however not more than 14 carbon atoms and / or carboxylic acids with oxygen hetero atoms attached to the carbon chain, having between 6 and 26 atoms in the carbon hetero atom chain, and / or aliphatic phosphonic acids with at least 4, but not more than 18 atoms of carbon, b) at least one amine, which has at least one oxybis (alkylamine) unit with tertiary amino groups, the alkyl chains of this unit being composed in each case of not more than 4 carbon atoms, the molar ratio of the total amount of carboxylic acid and / or phosphonic acid groups of components a) with respect to oxybis (alkylamine) units of the at least one amine of component b) not greater than 5: 1, does not hinder not less than 1: 3, ii) an emulsifying system (II) consisting of c) ethoxylates / propoxylates of fatty alcohols with 8 to 18 carbon atoms in the alcohol with 2 to 6 ethylene oxide units and 4 to 8 propylene oxide units and d) fatty alcohols and / or fatty alcohol propoxylates with 12 to 24 C atoms in the alcohol and 0 to 3 propyl oxide units and / or the distillation residue of these fatty alcohols .
