Definitions

  • the invention relates to a method for coating a metal surface with a lubricating oil containing citric acid ester and its application to the coating of metal surfaces made of ferrous materials.
  • Metal sheets e.g. B. steel sheets or sheets of tinned steel, treated for the production of cans or similar containers with a corrosion-protecting lubricating oil, in order to prevent the formation of corrosion or abrasion during transport and storage.
  • a corrosion-protecting lubricating oil In view of the paintability or the removability of the lubricating oil with any cleaning agents, however, the layers produced must be extremely thin. With increasing shipping or export of sheets, the importance of such lubricating oils has increased significantly.
  • dioctyl sebazate has hitherto been applied to the metal sheets and then packaged with an anti-corrosive paper containing a volatile corrosion inhibitor.
  • the corrosion protection obtained in this way is unsatisfactory. It is also difficult to remove these oils, so that insufficient paint adhesion or uneven metal deposition can occur in the subsequent treatment.
  • the object of the invention is to provide a method for coating metal surfaces with lubricating oil which does not have the known, in particular the aforementioned disadvantages, and leads to treated metal surfaces which have superior results with regard to corrosion resistance, lubricity, paintability and printability as well as cleaning.
  • the object is achieved by designing the method of the type mentioned at the outset in accordance with the invention such that a lubricating oil which, in addition to citric acid ester, contains 5 to 40% by weight of a reaction product of organic carboxylic acid and amine, in an amount of Applying 4 to 250 mg / m 2 by electrostatic coating.
  • the content of the reaction product is given as a proportion of the lubricating oil.
  • a preferred embodiment of the invention is to apply a lubricating oil whose citric acid ester has the formula has, where R "R 2 and R 3 are hydrocarbon radicals having 1 to 8 carbon atoms.
  • the removability of the lubricating oil decreases with higher carbon chains.
  • citric acid esters are trimethyl citrate, triethyl citrate, tripropyl citrate, tributyl citrate and trioctyl citrate.
  • the corrosion protection achieved is unsatisfactory and the electrical conductivity of the lubricating oil increases, with the result that the film is more difficult to apply. If the hydrocarbon residue has 19 or more carbon atoms, the removability of the lubricating oil is reduced.
  • the carboxylic acids used can be both aliphatic and aromatic in nature.
  • propionic acid, butyric acid, caproic acid, caprylic acid, capric acid, lauric acid, oleic acid, benzoic acid, toluic acid, p-nitrobenzoic acid and tert-butylbenzoic acid are suitable.
  • Corrosion protection, removability, odor and electrical conductivity are particularly preferred caprylic acid, capric acid, lauric acid and benzoic acid.
  • a further advantageous embodiment of the invention therefore provides for the application of a lubricating oil, the reaction product of which is formed from a secondary or tertiary amine.
  • a lubricating oil the reaction product of which is formed from a secondary or tertiary amine.
  • Such amines are di- or trialkylamine, such as di- or tri-methylamine, -ethylamine, -butylamine, and also ethylhexylamine, but also amino alcohols, such as dimethylethanolamine, diethylethanolamine, dibutylethanolamine, dihexylethanolamine and the like.
  • cyclohexylamines such as dicyclohexylamine, and also morphine , Diethanolamine and methylmorpholine can be used.
  • the molar ratio of organic carboxylic acid to amine is preferably 1: 1.
  • the lubricating oil to be used in the process according to the invention can contain further additives which are conventional per se, such as animal or vegetable oil or synthetic esters, e.g. B. dioctyl sebazate, or acetylated trialkyl citrate, to adjust viscosity and conductivity.
  • Surfactants can be introduced to improve the removability of the lubricating oil.
  • the method according to the invention is suitable for coating a large number of metal surfaces. It is particularly applicable to the coating of sheet metal or strip made of steel or tinned steel.
  • a particularly suitable steel quality is so-called "tin-free steel", under which steel with combination layers of metallic chromium (e.g. 0.02 to 0.05 g / m 2 ) and chromium hydroxide (e.g. 0 , 2 to 0.5 g / m 2 , calculated as Cr (OH) 3. 3 H 2 0). These layers are produced by cathodic switching from electrolytes containing chromic acid and sulfuric acid or hydrogen fluoride.
  • Corrosion resistance 5 test sheets measuring 75 x 150 mm were coated with tarpaulin paper and wound into a package and sealed at the ends with adhesive tape. The package was then placed in the tester maintained at 50 ° C and 90% relative humidity for 20 days.
  • Lubricating oil removability Test sheets were placed in a 2% by weight sodium hydroxide solution at 80 ° C. and rinsed with water. The time until complete wettability with water is determined (the shorter the time, the better the removability).
  • Paint adhesion The sheets are coated with an epoxy phenol paint for cans in such a way that a layer weight of 50 ⁇ 5 mg / dm 2 results after the paint has hardened. The curing takes place at 200 to 205 ° C for a period of 10 minutes. The sheets are then cross-cut to the metal surface, so that squares of 1 mm 2 in size are produced. The degree of flaking is then determined and evaluated.
  • the lubricating oil was applied electrostatically to black plate by means of a coating device, so that a uniform layer weight of 25 mg / m 2 resulted.
  • the sheet treated in this way was then cut to 70 mm x 150 mm sections and subjected to the tests for lubricity, corrosion resistance, lubricant oil removability and paintability. The results of the test can be found in the final table.
  • the lubricating oil was examined in accordance with the information in Example 1. The results are also in the final table.
  • the lubricating oil was applied and tested under the conditions of Example 1. The results can be found in the final table.
  • Dioctyl sebazate with an electrical conductivity of 0.02 ⁇ S / cm was applied and tested under the conditions of Example 1.
  • Triethyl citrate with an electrical conductivity of 0.08 ⁇ S / cm was again applied and investigated under the conditions of Example 1.
  • the dibutylamine salt of caprylic acid was carried out as in Example 1, applied electrostatically and tested.
