Definitions

  • the invention relates to a method for improving the adhesion on a protective coated steel sheet, in which a Zn-Al-Mg-based protective coating is applied to the steel sheet in a continuous process and subjected to a surface treatment in a further step, wherein the application of an aqueous composition the natural, Al2O3 and MgO oxide layer is modified without depleting it.
  • the suggests WO2006045570A1 To increase this adhesion to the protective coated steel strip by modifying the natural oxide layer, without depleting this natural oxide layer.
  • a cooling of the steel sheet with an aqueous composition or a cooling medium which is to improve the natural oxide layer of the protective coating for example comprising Zn, Mg and Al.
  • Soluble salts for protecting the natural oxide layer or phosphates for stabilizing the sheet surface may be added to the aqueous composition.
  • such a process can not lead to a marked increase in adhesiveness.
  • the object of the invention is therefore to provide, starting from the initially described prior art, a method with which the surface of the protective coating can be modified with as little effort as possible in such a way that the adhesion to the protective-coated steel sheet is significantly increased.
  • the invention solves this problem by the fact that the protective coated steel sheet trained and then reacts the natural oxide layer with an aqueous fluoride-containing composition with reduction of their MgO content in order to modify the natural oxide layer.
  • the protective-coated steel sheet is dressed and the natural oxide layer then reacts with an aqueous fluoride-containing composition, it has surprisingly been found that the proportion of MgO in the natural oxide layer of the protective coating can be reduced in a gentle manner.
  • This modification of the oxide layer can result in a considerable increase in the adhesive strength, in particular with regard to the ready-to-wear and / or recoatability of a protective-coated steel sheet.
  • alos the connection of an adhesive can be improved, so as to preclude an adhesive failure at splices.
  • the invention can stand out from the prior art in that this improved adhesion can be achieved without picking the oxide layer.
  • the oxide film can be activated by the skin-pass coating of the present invention for fluoride-responsive depletion of MgO.
  • Al which has a relatively high oxygen affinity, can therefore form primarily in the oxide layer or the due to the MgO reduction, vacancies occupy the oxide layer.
  • the latter can in particular contribute to the fact that a diffusion of magnesium into the oxide layer or a magnesium breakthrough can decrease.
  • the oxide layer naturally forming on a Zn-Al-Mg protective coating can thus be shifted in terms of process engineering in an easy to handle manner in the direction of increased proportions of Al 2 O 3 and / or ZnO and reduced amounts of MgO. According to the invention, a particularly well reproducible method is thus created.
  • the unit of measurement is ppm ppm by weight.
  • the invention may be particularly suitable for improving the adhesion of an organic coating to the protective coated steel sheet.
  • the aqueous composition 20 to 3500 ppm F, optionally 0 to 3500 ppm Na, 0 to 20 ppm P, 0 to 10 ppm Fe, 0 to 10 ppm Ni, 0 to 10 ppm Mn and / or 0 to 10 ppm Si and the remainder H2O and production-related unavoidable impurities, for which purpose the aqueous composition may have a pH of 4 to 8 and a temperature of 30 to 95 ° C (degrees Celsius).
  • the reaction rate of the aqueous composition with the Zn-Al-Mg protective coating can be adjusted relatively easily to a belt running speed of the continuous process.
  • an acidic adjustment of the pH an increased reduction of the MgO content in the oxide layer can be ascertained.
  • a temperature of the aqueous composition of 45 to 90 ° C may be sufficient to further increase their reaction rate with the native oxide layer.
  • Fe, Ni, Mn, P and / or Si may be useful for initiating MgO reduction or stabilizing the modified oxide layer.
  • the unavoidable impurities may be less than 50 ppm in total.
  • a concentration of fluoride from 20 to 3500 ppm in the aqueous composition can be found to be directed to MgO of the oxide layer or Mg leaching.
  • a concentration of fluoride of from 30 to 1500 ppm, preferably from 30 to 300 ppm, may already be sufficient.
  • the protective coating can be surface-treated with the aqueous composition for 0.5 to 20 seconds (seconds), in particular 1.5 to 15 seconds (seconds).
  • a short treatment can be particularly well suited for a continuous process.
  • the duration of treatment may be shorter. For example, at 1500ppm fluoride with a treatment time of 1.5 seconds, the expense can be found, while with 20ppm fluoride a 20 second treatment time should be sought to reduce the MgO content of the natural oxide layer without depleting it.
  • the preparation of the aqueous composition can be simplified by using NaF.
  • the process according to the invention can be distinguished, in particular, by a protective coating which comprises 0.1 to 7% by weight of aluminum, 0.2 to 5% by weight of magnesium and the balance zinc and unavoidable impurities due to the production.
  • a protective coating which comprises 0.1 to 7% by weight of aluminum, 0.2 to 5% by weight of magnesium and the balance zinc and unavoidable impurities due to the production.
  • Such Zn-Al-Mg protective coatings can be particularly well reduced an oxide layer with respect to unmodified oxide layers of the same alloy composition in their MgO content, which can be used for a significant increase in the adhesive strength.
  • the protective coating specified above may contain 1 to 4% by weight of aluminum and 1 to 3% by weight of magnesium, in order to increase not only an improvement in the adhesive strength but also the reproducibility of the process.
  • the activation of the oxide layer for a subsequent surface treatment can be improved if, when the steel sheet is applied by casting, dressing impressions are introduced into the protective coating.
  • these dressing impressions preferably in their edge regions, form an improved attack surface for fluoride in order to increasingly dissolve MgO from the natural oxide layer.
  • MgF 2 magnesium fluoride
  • MgF 2 magnesium fluoride
  • more Zn5 (OH) 6 (CO3) 2 zinc hydroxide carbonate
  • the fluoride-containing aqueous composition can be easily removed from the surface of the protective coating if the protective coating is rinsed with another liquid immediately after the surface treatment with the first fluoride-containing aqueous composition.
  • this aftertreatment with such a liquid can additionally increase the removal of MgO, with it being possible in particular for H2O to be distinguished as the liquid.
  • the second liquid has up to 20 ppm of P and / or Si, as well as the remainder of H 2 O and unavoidable impurities, then the native oxide layer reduced in MgO can be further stabilized. With P it is to be expected that this occurs as phosphate in the liquid.
  • the rinsing action of the second liquid can be significantly improved if the liquid has a temperature of 20 to 90 ° C, in particular from 35 to 85 ° C.
  • Simple process conditions can occur when the aqueous composition and / or the liquid is applied to the protective-coated steel sheet in a spraying, dipping or rolling process.
  • the invention may be distinguished from the known one if an aqueous fluoride-containing composition is used to reduce the MgO content of the natural oxide layer of a Zn-Al-Mg protective coating on a dressed steel sheet, without thereby dekapieren the natural oxide layer.
  • a Zn-Al-Mg-based protective coating is first applied to a moving steel sheet 2 by means of a hot-dip process 3.
  • Hot-dip galvanizing strip galvanizing
  • hot-dip process 3 the representation of the relevant plant parts of the device 1 for clarity was limited to a continuous furnace 18, a molten bath 3, a scraper 19 for adjusting the coating layer and a cooling 20.
  • the steel sheet 2 After carrying out the hot-dip process 3, the steel sheet 2 has a Zn-Al-Mg protective coating which forms a natural oxide layer 9.
  • This native oxide layer 9 is known to comprise Al 2 O 3 10, MgO 11, and also, albeit to a minor extent, ZnO 12.
  • the proportion of MgO 11 in the oxide layer 9 is comparatively high, as after Fig. 2 can be recognized.
  • MgO 11 is seen on the bright surface, Al 2 O 3 10 on the dark surface and ZnO 12 on a mixture of light and dark surfaces. Due to a predominantly bright MgO surface on the surface of the Zn-Al-Mg protective coating, a considerable reduced adhesion is to be expected.
  • such dominant MgO accumulations in the oxide layer 9 are avoided by passing the steel sheet 2 provided with a Zn-Al-Mg protective coating through a skin pass mill 5 and thus preparing it to modify its native oxide layer 9 - prepared for surface treatment 6
  • this process step is realized with spray bars 8 arranged on both sides of the steel sheet 2, which apply or spray on the aqueous fluoride-containing composition 7 onto the steel sheet 2.
  • spray bars 8 arranged on both sides of the steel sheet 2, which apply or spray on the aqueous fluoride-containing composition 7 onto the steel sheet 2.
  • an application with a rolling or dipping method not shown is conceivable.
  • the fluoride of the aqueous composition subsequently releases MgO 11 from the oxide layer 9 and converts it into the aqueous composition 7.
  • the amount of fluoride, measured with a fluoride-sensitive electrode, in the aqueous composition 7 is adjusted to a dissolution of Mg of the oxide layer 9.
  • the proportion of MgO 11 in the native oxide layer 9 is thus reduced, so that due to the high oxygen affinity of Al increased Al2O3 10 can be expressed on the modified native or native oxide layer 9.
  • Fig. 3 Although also shows MgO 11 on light surfaces, compared to Fig. 2 however, the MgO 11 content is extremely low. For example, Al2O3 10 (dark area) and ZnO 12 or Zn5 (OH) 6 (CO3) 2 (mixture of light and dark areas) clearly outweigh each other.
  • the modified natural oxide layer 9 after Fig. 3 essentially comprises Al 2 O 3 10, thus forming a barrier layer which not only reduces the breakdown of Mg into the oxide layer 9 to form MgO 11, but also the diffusion of O through the oxide layer. Even with comparatively long storage times of the steel sheet 2, this modified natural oxide layer 9 still exhibits a comparatively high adhesiveness.
  • the pH may be adjusted to slightly acid in a range of 4 to 8.
  • the aqueous composition contains 20 to 3500 ppm F, optionally 0 to 3500 ppm Na, 0 to 20 ppm P, 0 to 10 ppm Fe, 0 to 10 ppm Ni, 0 to 10 ppm Mn and / or 0 to 10 ppm Si and the remainder H2O and production-related unavoidable impurities, for which purpose the aqueous composition has a pH of 4 to 8 and a temperature of 30 to 95 ° C (degrees Celsius) ,
  • Concentration of fluoride from 30 to 1500 ppm, preferably from 30 to 300 ppm shown.
  • the protective coating is surface treated immediately after treatment via spray bar 17 with a second liquid 15.
  • This second liquid 15 consists of H 2 O, but may also have P or Si less than 20 mg / l and unavoidable impurities, P being optionally present as the phosphate in the liquid 15.
  • a treatment time of 1 to 10 seconds has been found to be sufficient.
  • Table 1 the examined steel sheets in comparison sheet steel coating

  • the steel sheets A and C were treated with the aqueous composition 7 for 20 seconds. Subsequently, the steel sheets A and C were rinsed with H2O for 10 seconds. In this liquid 15, a temperature of 35 degrees Celsius was set.
  • All the steel sheets A, B, C and D were then provided with an organic coating, namely a one-part epoxy resin adhesive (e.g., BM1496), and the adhesive strength of the adhesive on the protective coating was determined by a tensile shear test.
