Definitions

  • the invention relates to a method for passivating the surface of tin-plated steel strips, which are moved at a belt speed through a coating plant, by anodic oxidation and post-treatment of the tinned steel strip with a chromium-free aftertreatment agent.
  • the invention further relates to the use of complex-linked transition metal agents or organic additives normally used to disperse or improve wetting, as a chromium-free aftertreatment agent in the manufacture of tinned steel strips.
  • the invention further relates to a tin-plated steel strip or sheet with a carrier layer of a fine or Feinstblech made of steel and a deposited thereon tin layer and a surface layer of a chromium-free aftertreatment agent.
  • Tinplate is a versatile, economically and ecologically advantageous material that is mainly used in the packaging industry. Tinplate is cold-rolled steel sheet with a thickness of up to 0.5 millimeters, which is coated with a thin layer of tin to protect the steel sheet from corrosion. The tin layer is, for example, applied electrolytically to the metal sheet.
  • the coated steel sheet is chemically or electrochemically passivated and then greased to make the tin-plated steel resistant to oxidation and to lower the coefficient of friction, so that the tinned steel during subsequent processing, eg. in the production of tinplate packaging for food, can be processed better.
  • the passivation is usually carried out using Cr 6+ -containing solutions.
  • DE4205819A discloses an anhydrous composition for producing anticorrosive coatings on metallic surfaces based on silane compounds and compounds of tetravalent titanium or zirconium.
  • EP1002143A discloses a process for the alkaline passivation of galvanized and alloy galvanized steel surfaces as well as of aluminum and its alloys in strip lines. This passivation with an aqueous solution results in a corrosion protection layer, which can serve as the basis for subsequent painting.
  • EP1270764A discloses a surface-treated tinplate comprising an alloy layer on a surface of a steel sheet, a tin layer coated on the alloy layer so that the alloy layer is exposed on an area of 3.0% or more, and thereon a film comprising P and Si with a coating weight of 0.5 to 100 mg / m 2 or 250 mg / m 2 applied to the exposed alloy layer and the tin layer.
  • Chromium-free aftertreatment agents for tinplate are described in US 2009/0155621 Al and the publications cited therein. Disadvantages of the prior art
  • the passivation here must prevent excessive growth of the tin oxide layer during storage of the coated steel sheet or the food containers produced therefrom until painting and beyond until consumption of the preserve.
  • the passivation should prevent discoloration of the coated metal surface. Such discolorations occur, for example, in the sterilization of cans with sulfur-containing contents, because the sulfur reacts with the tin of the coated sheet steel surface, if it is not sufficiently passivated.
  • the matt discoloration (marbling) or gold coloration of the surface of the packaging may give the consumer the impression that the product is spoiled.
  • the reaction with sulfur can also lead to paint adhesion problems, which can be avoided by passivation of the coated steel sheet.
  • the passivation must also ensure the resistance of the painted metal container after filling with food against acids contained in the food, such.
  • Such acid anions in the product can cause delamination of the inner coating of the container in case of insufficient passivation.
  • the cold-rolled fine or ultra-fine sheet is first melted by heating to temperatures above the tin melting point after tinning and then quenched in a water bath. Passivation is then carried out by treating the tinned steel sheet with a chromate solution and finally rinsing with demineralized water and drying it thermally. This is followed by electrostatic lubrication with dioctyl sebacate (DOS) or acetyltributyl citrate (ATBC).
  • DOS dioctyl sebacate
  • ATBC acetyltributyl citrate
  • the Cr 3+ precipitates as Cr 3+ hydroxide.
  • the passivation layer no longer contains Cr 6+ ions after rinsing and drying the tinplate surface.

  • an improved paint adhesion and resistance to acids in foods, especially against sulfur-containing amino acids can be achieved.
  • an anodic oxidation of the tin surface is provided.
  • the invention is based on the recognition that the passivation of the tinned surface of the steel strip by aftertreatment with a chromium-free aftertreatment agent alone is not sufficient to protect the surface over the entire surface and permanently against corrosion and discoloration (marbling).
  • chromium-free aftertreatment agents do not protect the tin-plated steel strip surface from reaction with sulfur.
  • the resistance of the tinned steel strip surface against corrosion and reaction with sulfur increases considerably can be, if prior to the post-treatment with a chromium-free aftertreatment agent initially carried out an inerting of the tinned steel strip surface by an anodic oxidation.
  • the anodic oxidation produces an oxide layer with a layer thickness in the nm range on the tinned steel strip surface.
  • the oxide layer is essentially a layer of tetravalent tin oxide (SnO 2 ) which is substantially more inert than divalent tin oxide (SnO). If, according to the invention, a thin surface layer of a chromium-free aftertreatment agent is applied to this oxide layer, the surface of the tinned steel strip is fully and effectively protected against corrosion and against reaction with sulfur.
