Definitions

  • the invention relates to a method for applying phosphate coatings on iron, zinc and / or aluminum by means of a phosphating solution containing zinc, manganese, phosphate and accelerator.
  • GB-PS 983 924 a method for applying phosphate coatings on iron or zinc surfaces by spray treatment with a solution of a temperature of 38 ° C or less is known, which contains zinc and manganese phosphate and an oxidizing accelerator.
  • the manganese content of the solution is between 5 and 50% by weight of the zinc content.
  • DE-OS 28 18 426 shows that the introduction of boron fluoride has advantages and in particular leads to the formation of satisfactory phosphate layers on aluminum or greatly improves the quality of the phosphate layers on iron surfaces.
  • oxidizing accelerators for zinc and phosphate-containing phosphating solutions have been proposed in recent years. These include chlorates, nitrates, organic nitro compounds such as sodium metanitrobenzenesulfonate and dinitrobenzenesulfonate, hydrogen peroxide, nitrites, bromates and iodates.
  • GB-PS 15 42 222 describes the use of chlorate and nitrobenzenesulfonate as accelerators in a phosphating process working with zinc and phosphate.
  • the preferred accelerators in the processes according to GB-PS 983 924 or DE-OS 28 18 426 are nitrate, optionally with nitrite. Chlorate is also referred to as a possible additive.
  • the object of the invention is to provide a phosphating process which leads to flawless phosphate layers on iron, zinc and / or aluminum which are firmly adhered to the substrate and which - particularly at low temperatures - runs at a high layer formation rate.
  • the object is achieved by designing the method of the type mentioned at the outset in accordance with the invention in such a way that the metal surfaces are brought into contact with a phosphating solution whose manganese content is 5 to 33% by weight of the zinc content and which contains chlorate and nitrobenzenesulfonate as accelerators .
  • a preferred embodiment within the method according to the invention is to use a phosphating solution which contains.
  • the manganese content should in particular make up 5 to 20% by weight, preferably 9 to 13% by weight, of the zinc content.
  • a phosphating solution which additionally contains up to 0.5% by weight, preferably 0.01 to 0.03% by weight of Ni ions, and / or additionally aliphatic a- Hydroxy acids or their water-soluble salts, such as tartaric acid or tartrate, in amounts of up to 0.8% by weight, preferably 0.02 to 0.2% by weight (calculated as tartrate), and / or additionally simple, but in particular complex Contains fluoride in amounts of up to 0.4% by weight, preferably 0.05 to 0.1% by weight (calculated as F).
  • accelerators in addition to the accelerator pair chlorate and nitrobenzenesulfonate required to achieve a high layer formation rate, other accelerators, in particular nitrate, can also be used. If nitrate is used, its amount should be less than 2.25% by weight. The preferred range is between 0.4 and 1.0% by weight. Nitrite should result from the inevitable formation nitrous gases should not be added if possible. Otherwise, other additives described in connection with the method according to GB-PS 983 924 and DE-OS 28 18 426 can be made.
  • the pH of the phosphating solution should be 3.4 to 4.4 so that the process according to the invention leads to the desired phosphate layer formation in a sufficiently short time, in particular at the temperatures of 25 to 50 ° C. or particularly advantageously from 25 to 35 ° C. .
  • the total acid 20 and the free acid are preferably 0.8 to 1.0 points.
  • the phosphating solution used in the method according to the invention can be prepared by dissolving the components in water. It is preferably obtained by diluting concentrates which contain the active components in the same ratio as in the working phosphating solution.
  • the contact between the metal surface and the phosphating solution is usually effected by spraying and is about 50 to 120, preferably 80 seconds. Before this, the metal surfaces should be cleaned and rinsed in a conventional manner. After the phosphating layer formation z. B. rinsed with a dilute aqueous solution of chromium compounds and then dried.
  • a phosphating solution was prepared that contained.
  • the phosphate layers produced were smooth, completely opaque and adherent.
  • the sheets were then cathodically electrocoated with a varnish (ED 3002 from International Paints) and dried in the oven at 182 ° C. for 20 minutes.
  • the dry film thickness of the paint was 18 1 1m.
  • the sheets were then cross cut and subjected to the salt spray test according to ASTM B 117-64 for a period of 500 hours. After the test was completed, adhesive tape was stuck over the cross interfaces and removed again to determine the amount of dissolved paint. No paint removal was observed.
  • the example illustrates that the process according to the invention allows good phosphate layers to form within a short treatment time and at low treatment temperatures.
