Definitions

  • the invention relates to a process for the preparation of 0 / W (oil-in-water) rust protection emulsions based on an oil component, water, at least one emulsifier component and a corrosion inhibitor.
  • 0 / W oil-in-water
  • rust protection emulsions based on an oil component, water, at least one emulsifier component and a corrosion inhibitor.
  • the compliance of certain conditions leads to particularly stable and low-viscosity O / W emulsions, ensure ei ⁇ NEN good corrosion protection 'for metal surfaces of iron and steel.
  • Rust protection emulsions are used • for the temporary protection of metallic workpieces from atmospheric influences which cause corrosion. They contain essentially non-polar or polar oils, emulsifiers, corrosion inhibitors and water. Their effect is based on the adsorption of inhibitor molecules on the metal surface and the formation of a protective film from erosion components, which acts as a diffusion barrier for atmospheric oxygen and water. Th. Forster et al. report in "Surface-Surface", 1989, No. 4, pp. 8 to 12, about the mode of action and methods of investigation of rust protection emulsions. Other commercially available systems are based on oil concentrates which contain emulsifiers and corrosion inhibitors, but no water. This means that the emulsifiers and corrosion inhibitors used must be oil-soluble. For the production of O / W emulsions from such oil concentrates, this also means that such systems have to be self-cleaning.
  • phase inversion ie at higher temperatures the outer, aqueous phase can become the inner phase.
  • This process is generally reversible, that is to say that the original type of emulsion re-forms on cooling.
  • position of the phase inversion temperature depends on many factors, such as the type and Phasenvo ⁇ lumen of the 'oil component of the hydrophilic character and structure of the emulsifier or the composition of the EmuIgatorSystems, verglei ⁇ che for example, K. Shinoda and H. Kunieda in "Encyclopedia of Emulsion Technology", Vol. I, ed. P. Becher 1983 (M. Decker, NY), pp. 337 to 367.
  • the object of the invention is to develop a suitable process for the preparation of O / W rust protection emulsions which contain entirely or predominantly polar carboxylic acids as corrosion inhibitors.
  • Such O / W emulsions are said to be capable
  • ER S ATZBLATT be inverted at temperatures below 100 ° C in order to achieve particularly stable, finely divided and low-viscosity emulsions.
  • the emulsions obtained in this way should be able to be diluted with water, the dilutions should also be stable and provide effective corrosion protection.
  • the invention accordingly relates to a process for the preparation of stable, low-viscosity O / W antirust emulsions, wherein a mixture containing an oil component, water and at least one emulsifier component, at a temperature at which all components of the mixture in are in liquid form, emulsify and the emulsion formed is heated to a temperature within or above the phase inversion temperature range of the emulsion or the mixture is emulsified at a temperature within or above the phase inversion temperature range, then the emulsion to a temperature below this temperature range cooled and optionally diluted with water, characterized in that a mixture of the following composition is used to form the emulsion:
  • R is a straight-chain or branched, saturated or unsaturated alkyl radical having 6 to 22 carbon atoms or a radical of the general formula (II)
  • R- saturated, straight-chain or branched alkyl radical having 8 to 18 carbon atoms
  • a co-emulsifier component consisting of at least one fatty alcohol with 12 to 22 carbon atoms
  • carboxylic acids which are able to be effective in their acidic form as corrosion inhibitors and on the other hand the way of producing stable and low-viscosity O / W emulsions which contain such corrosion inhibitors.
  • the carboxylic acids must not impair or even prevent a phase version of the emulsion.
  • suitable emulsifiers which, on the one hand, form such stable emulsions with the corrosion inhibitors mentioned and, on the other hand, do not adversely affect the effectiveness of the corrosion inhibitors on the substrate surface under atmospheric corrosion conditions.
  • the method according to the invention makes it possible to produce such stable and low-viscosity O / W rust protection emulsions.
  • the mixture of all of the emulsion components listed, including the carboxylic acids, is subjected to a phase inversion while the mixture or the emulsion already present is heated to a temperature within or above the phase inversion temperature range.
  • corrosion inhibitors in the desired finely divided form in the emulsion and stably emulsify therein.
  • phase inversion takes place below 100 ° C. This phase inversion takes place both with non-polar oils (paraffin oils) and with slightly polar oils (mineral oils).
  • PIT method i.e. Phase inversion temperature method
  • rust protection emulsions produced show - compared to emulsions of the same composition which have not undergone phase inversion - higher storage stability.
  • more than 40 days pass in the corrosion test, assessed according to DIN 51 359, until 100% corrosion is observed. The effectiveness of the corrosion protection is therefore of the same order of magnitude as the products belonging to the state of the art.
  • Oils of different polarity for example paraffin oils or mineral oils, can be used as the oil component.
  • So-called ester oils ie fatty acid glycerides, can also be used in a mixture with mineral oils and / or paraffin oils.
  • paraffin oils or mineral oils are preferably used as oil component a).

  • adducts of ethylene oxide with such fatty alcohols are usually mixtures of polyglycol ethers of the starting fatty talc alcohols, the average degree of oxyethylation of which corresponds to the molar amount of ethylene oxide added.
