Definitions

  • the invention relates to a method for treating metal surfaces, optionally provided with a chemical conversion coating, by contacting them with an aqueous solution which contains reactive organosilane, and then drying the solution.
  • a non-contiguous sealing layer of a hydrophobizing agent e.g. to produce using organic substances, for example based on polyisocyanate modified resin condensation products (DE-AS 11 47 820) or to seal them with drying oils or low-viscosity lacquers (H. Fortmann "post-treatment process of phosphated iron parts", metal goods industry and electroplating MSV No. 6 ( 1943), page 229).
  • these agents could not prevail over the chrome-containing aftertreatment solutions for reasons of low quality.
  • many of these funds did not lead to useful results.
  • a chemically applied also for the aftertreatment conversion coatings, in particular phosphate coatings particular method provides for the use solutions containing a particular P oly-4-vinyl phenol compound (DE-OS 31 46 265).
  • the pH of the upcoming used solution is usually in the alkaline range, which can optionally be connected in the treatment of mwandlungsüberratn U with metal surfaces provided with the disadvantage of a partial delamination.
  • organosilanes etallober- as an adhesion promoter for generating well-adhering coatings on M insert surfaces or previously provided with a conversion coating metal surfaces
  • organosilanes etallober- as an adhesion promoter for generating well-adhering coatings on M insert surfaces or previously provided with a conversion coating metal surfaces
  • the object of the invention is to provide a method for treating metal surfaces, optionally provided with a chemical conversion coating, which additionally improves in particular the corrosion protection of the metal surface and is free from any environmental and application problems.
  • the object is achieved in that the method of the type mentioned at the outset is designed in accordance with the invention in such a way that the metal surfaces which are optionally provided with a chemical conversion coating are brought into contact with a solution which, in addition to organosilane, additionally contains titanium and / or zirconium fluoride compound.
  • aqueous solution includes solutions which contain certain amounts of alcohol or similar water-soluble solvents as solubilizers.
  • A is optionally provided with a chemical Umwandlungsuberzug metal surfaces with a Contact solution containing an organosilane with at least 2 reactive groups.
  • Organosilanes suitable for carrying out the process according to the invention are described by Ullmann lc, in particular in Tables 6 to 8 on pages 499, 501 and 503.

  • fluorotitanic or zirconic acid, ammonium fluorotitanate or zirconate are used as titanium or zirconium fluoride compounds.
  • the solution to be used in the method according to the invention is characterized by high stability, i.e. no components fail when used.
  • the treatment solution can be applied in any manner. Suitable forms of application are e.g. Spreading, spraying, rolling up, dipping or flooding.
  • the drying temperature can be selected within wide limits and is generally in the range from 60 to 300 ° C.
  • steels, alloyed steels, aluminum and zinc and their alloys, steels plated with zinc or tin or other galvanized or tinned steels can be treated with the method according to the invention.
  • the aforementioned substrates can also have been provided beforehand with zinc or iron phosphate layers or chromate layers.
  • the coatings produced on the metal surfaces with the process according to the invention provide a high level of corrosion protection and excellent adhesion properties for the subsequent painting, the effect can be enhanced if the process is used for the aftertreatment of metal surfaces previously provided with a conversion coating.
  • Preferred embodiments of the invention provide that the metal surfaces, optionally provided with a chemical conversion coating, are brought into contact with a solution which contains organosilane in a concentration of 0.5 to 100 g / l, preferably 1 to 50 g / 1, or contains the titanium and / or zirconium fluoride compound in a concentration of 0.01 to 5 g / 1, preferably in a concentration of 0.05 to 1 g / l or in which the ratio of organosilane to titanium and / or Z irkonfluorid compound in the range of (10 to 200): 1, preferably from (20 to 100): 1, is located.
  • a further preferred embodiment of the invention provides that the metal surfaces, optionally provided with a chemical conversion coating, are brought into contact with the solution in such a way that a layer weight of 10 to 300 mg / m 2 is obtained after the subsequent drying of the solution film.
  • the mixture mixed with 1 l of water had a pH of 3.0.
  • the coated panels were provided with an acrylate lacquer 20-25 / um thickness.
  • the paint was baked at 200 ° C for 3 min.
  • sample sheets of the same nature were treated with solutions 1 to 4 which corresponded to the aforementioned solutions but did not contain any titanium and / or zirconium fluoride compound.
  • solutions 1 to 4 which corresponded to the aforementioned solutions but did not contain any titanium and / or zirconium fluoride compound.
  • the type of treatment and painting matched.
  • alkaline-cleaned aluminum sheets were chromated with a 7% by weight chromating solution, rinsed with water and treated with acrylate paint as described above.
  • the salt water spray test was carried out in accordance with JIS Z-2317, in which a cross cut reaching to the metal surface was made before the spray treatment. It was time registered until the cross-scored paint layer flaked off.
  • Erichsen checkerboard field test Here, the lacquer layer is scored in 100 checkerboard fields, each 1 mm. Then press the 3 mm Erichsen tester from the back of the surface provided with the checkerboard fields and stick adhesive tape on the curvature of the lacquer surface. Then you quickly tear off the tape from the paint surface and register the number of checkerboard areas whose paint layer has been preserved.
