  • 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.

  • 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.

  • 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).
