  • Patent Document 8 discloses a method for manufacturing a 3-piece can stripe laminate steel sheet.
  • Patent document 9 discloses a steel sheet for a container, comprising a Ni plating layer or a Fe-Ni alloy plating layer formed on a surface of the steel sheet where a Sn plating layer of is plated on the Ni plating layer or the Fe-Ni alloy plating layer.
  • the Sn plating layer is partially alloyed with the underlying Ni or Fe-Ni layer, while a part of the Sn plating layer is partially left.
  • a chromate film which is subjected to an electrolytic chromate process is used for a steel sheet used as a base of a laminate film in most cases.
  • the chromate film has a two-layered structure including a metal Cr layer and a hydrated oxidation Cr layer formed thereon. Accordingly, the laminate film (an adhesive layer if an adhesive is adhered to the film) secures adhesion with the steel sheet through the hydrated oxidation Cr layer of the chromate film.
  • this adhesion is obtained by a hydrogen bond of a hydroxyl group of the hydrated oxidation Cr with a functional group, such as a carbonyl group or an ester group, of the laminate film.
  • the above-mentioned inventions can obtain an effect of reliably advancing the preservation of the global environment.
  • cost and quality competition between materials such as PET bottles, bottles, paper and so on is intensified in a beverage container market, and there is a need for excellent adhesion and corrosion resistance over the conventional paining technique, and more excellent can manufacturing workability, particularly, film adhesion, worked film adhesion, corrosion resistance and so on for the above-described steel sheet for the laminate container.
  • the present invention has been made in consideration of the above problems, and it is an object of the present invention to provide a steel sheet for a container, which is excellent in adhesion, corrosion resistance, weldability, can manufacturing workability and external appearance.
  • the present inventors have reviewed use of a Zr film as a new film to replace a chromate film, discovered that a composite film including the Zr film and a phosphoric acid film and a phenol resin film forms a very strong covalent bond with paints or a laminate film, which may result in excellent can manufacturing workability over a conventional chromate film, and made the present invention based on the discovery as follows.
  • the steel sheet for a container of the present invention has excellent drawing-ironing, weldability, corrosion resistance, paints adhesion, film adhesion and external appearance.
  • An original sheet used in the present invention is not particularly limited but may typically use a steel sheet used as a material for a container.
  • a manufacturing method and material quality of the original sheet are not particularly limited, but the original sheet is manufactured from a typical billet manufacturing process through hot rolling, pickling, cold rolling, annealing, skin pass rolling processes and so on.
  • a metal surface treatment layer is formed on a surface of the steel sheet
  • a method of forming the layer is not particularly limited but may use, for example, an electroplating method, a vacuum deposition method, a sputtering method or others methods known in the art, and further may be combined with a heating process to form a diffusion layer.
  • an Ni plating layer including Ni of 5 mg/m 2 ⁇ 150 mg/m 2 , or a Fe-Ni alloy plating layer including Ni of 5 mg/m 2 ⁇ 150 mg/m 2 is formed on the surface of the steel sheet, Sn plating layer of 300 mg/m 2 ⁇ 3000 mg/m 2 is plated thereon, and then, a tin melting process is performed to alloy part or all of the underlying Ni layer and part of the Sn plating layer while partially leaving the Sn plating layer.
  • the purpose of performing the Ni or Fe-Ni plating process to form the Ni plating layer is to secure corrosion resistance. Since Ni is high corrosion resistant metal, the corrosion resistance of the alloy layer formed in the tin melting process can be enhanced by plating Ni on the surface of the steel sheet.
  • the amount of Ni used is necessary to be more than 5 mg/m 2 since the effect of Ni on enhancement of the corrosion resistance of the alloy layer appears when the amount of Ni is more than 5 mg/m 2 .
  • the effect of enhancement of the corrosion resistance of the alloy layer increases with increase of the amount of Ni. However, if the amount of Ni exceeds 150 mg/m 2 , the enhancement effect is saturated. In addition, Since Ni is expensive, it is uneconomical to plate Ni of more than 150 mg/m 2 . Accordingly, it is preferable to plate Ni of 5 mg/m 2 ⁇ 150 mg/m 2 .
  • an Ni diffusion layer is to be formed, although a diffusion process is performed to form the Ni diffusion layer in an annealing furnace after plating Ni, even when nitriding treatment is performed before or after the Ni diffusion process or at the same time of the Ni diffusion process, the effect of Ni on the Ni plating layer and the effect of a nitriding treatment layer can be obtained.
  • the electroplating method generally known in the art may be used as the Ni plating and Fe-Ni alloy plating methods.
  • the Sn plating process is performed after the Ni plating.
  • the Sn plating used herein is a plating using metal Sn, however impurities may be inevitably mixed into the Sn plating or a very small amount of element may be added to the Sn plating.
  • the Sn plating method is not particularly limited and may be the electroplating method known in the art or a method of digesting and plating melted Sn.
  • the purpose of Sn plating is to secure corrosion resistance and weldability. Since Sn has high corrosion resistance, a Sn alloy formed in the tin melting process, which will be described later, as well as Sn metal shows excellent corrosion resistance. The excellent corrosion resistance of Sn is remarkably enhanced when the amount of Sn is more than 300 mg/m 2 .
  • the corrosion resistance of Sn increases with increase of the amount of Sn plating, but if the amount of Sn plating exceeds 3000 mg/m 2 , the effect of Sn is saturated. Accordingly, it is preferable to set the amount of Sn plating to be less than 3000 mg/m 2 from an economical point of view.
  • the amount of Sn plating is defined to be 300 mg/m 2 ⁇ 3000 mg/m 2 .
  • the tin melting process is performed after the Sn plating.
  • the purpose of tin melting process is to melt Sn and alloy the melted Sn with an underlying steel sheet or underlying metal to form a Sn-Fe or Sn-Fe-Ni alloy layer, enhance corrosion resistance of the alloy layer, and leave Sn metal partially.
  • the metal tin may be left in various forms of island, pool, stripe and so on.
  • Sn of 560 mg/m 2 ⁇ 5600 mg/m 2 is plated on the surface of the steel sheet and some of the Sn plating layer is alloyed by the tin melting process.
  • Sn has excellent workability, weldability and corrosion resistance
  • Sn of more than 560 mg/m 2 is needed from a viewpoint of corrosion resistance.
  • the corrosion resistance increases with increase of the amount of Sn plating, but if the amount of Sn plating exceeds 5600 mg/m 2 , the effect of Sn is saturated. Accordingly, it is preferable to set the amount of Sn plating to be less than 5600 mg/m 2 from an economical point of view.
  • the Sn alloy layer is formed to further enhance the corrosion resistance.
  • the Zr film, the phosphoric acid film and the phenol resin film may show an effect to some degree even when they are separately used, but do not show sufficiently practical performance.
  • a composite film including two or more of the Zr film, the phosphoric acid film and the phenol resin film shows excellent practical performance.
  • a composite film including the Zr film and one or more of the phosphoric acid film and the phenol resin film shows further excellent practical performance.
  • the amount of film is small, since the Zr film, the phosphoric acid film and the phenol resin film complement their respective characteristics, a composite film including all of the Zr film, the phosphoric acid film and the phenol resin film show more stable practical performance.
  • a single film including two or more of Zr, phosphoric acid compound and phenol shows low practical performance of corrosion resistance and adhesion as compared to the composite film including two or more of the Zr film, the phosphoric acid film and the phenol resin film. The reason for this is not obvious, but it is believed that the mixture of Zr, phosphoric acid compound and phenol hinders performance of individual components.
  • the role of the Zr film is to secure the corrosion resistance and the adhesion.
  • the Zr film is formed of Zr compounds such as Zr oxide, Zr hydroxide, Zr fluoride, Zr phosphate or the like, or a composite film including these components.
  • the Zr compounds have excellent corrosion resistance and adhesion. Accordingly, the corrosion resistance and the adhesion increase with increase of the amount of the Zr film, and if the amount of Zr metal exceeds 1 mg/m 2 , the corrosion resistance and the adhesion are secured sufficiently from a practical point of view.
  • the increase of the amount of the Zr film enhances the corrosion resistance and the adhesion
  • the amount of Zr in the Zr film exceeds 500 mg/m 2 , the Zr film gets too thick, which results in deterioration of the adhesion of the Zr film, and electric resistance increases, which results in deterioration of weldability. Accordingly, it is preferable to set the amount of Zr in the Zr film to be 1 mg/m 2 ⁇ 500 mg/m 2 .
  • spots adhered to the film may appear as external appearance spots if the amount of Zr in the Zr film exceeds 15 mg/m 2 , it is more preferable to set the amount of Zr in the Zr film to be 1 mg/m 2 ⁇ 15 mg/m 2 . In addition, to more stabilize the external appearance spots, it is preferable to set the amount of Zr in the Zr film to be 0.1 mg/m 2 ⁇ 9 mg/m 2 .
  • the role of the phosphoric acid film is to secure the corrosion resistance and the adhesion.
  • the phosphoric acid film is formed of Fe phosphate, Sn phosphate, Ni phosphate, Zr phosphate, or a film such as a phosphate-phenol resin film, or a composite film including these components. These phosphoric acid films have excellent corrosion resistance and adhesion. Accordingly, the corrosion resistance and the adhesion increase with increase of the amount of the phosphoric acid film, and if the amount of P exceeds 0.1 mg/m 2 , the corrosion resistance and the adhesion are secured sufficiently from a practical point of view.
  • the increase of the amount of the phosphoric acid film enhances the corrosion resistance and the adhesion
  • the amount of P in the phosphoric acid film exceeds 100 mg/m 2 , the phosphoric acid film gets too thick, which results in deterioration of the adhesion of the phosphoric acid film, and electric resistance increases, which results in deterioration of weldability. Accordingly, it is preferable to set the amount of P in the phosphoric acid film to be 0.1 mg/m 2 ⁇ 100 mg/m 2 .
  • spots adhered to the film may appear as external appearance spots if the amount of P in the phosphoric acid film exceeds 15 mg/m 2 , it is more preferable to set the amount of P in the phosphoric acid film to be 0.1 mg/m 2 ⁇ 15 mg/m 2 . In addition, to more stabilize the external appearance spots, it is preferable to set the amount of P in the phosphoric acid film to be 0.1 mg/m 2 ⁇ 8 mg/m 2 .
  • the role of the phenol resin film is to secure the adhesion.
  • the phenol resin film has very excellent adhesion with paints or a laminate film since the phenol resin is an organic substance. Accordingly, the adhesion increases with increase of the amount of the phenol resin film, and if the amount of C exceeds 0.1 mg/m 2 , the adhesion is secured sufficiently from a practical point of view.
  • the increase of the amount of the phenol resin film enhances the adhesion, if the amount of C in the phenol resin film exceeds 100 mg/m 2 , electric resistance increases, which results in deterioration of weldability. Accordingly, it is preferable to set the amount of C in the phenol resin film to be 0.1 mg/m 2 ⁇ 100 mg/m 2 .
  • spots adhered to the film may appear as external appearance spots if the amount of C in the phenol resin film exceeds 15 mg/m 2 , it is more preferable to set the amount of C in the phenol resin film to be 0.1 mg/m 2 ⁇ 15 mg/m 2 . In addition, to more stabilize the external appearance spots, it is preferable to set the amount of C in the phenol resin film to be 0.1 mg/m 2 ⁇ 8 mg/m 2 .
  • a method of forming the films as described above includes a method of digesting a steel sheet into an acid solution into which Zr ions, phosphoric ions and low molecular phenol resin are dissolved and a method using a cathode electrolytic process.
  • adhesion is irregular since various films are formed by etching a base.
  • this digesting method is disadvantageous in industrial respects since a long process time is taken.
  • the cathode electrolysis method is very advantageous in industrial respects since it takes a short time, for example, several seconds to several ten seconds, to process a uniform film, in addition to effects of compulsory charge movement, surface cleaning by hydrogen generated at a steel sheet interface and promotion of adhesion by increase of pH. Accordingly, it is preferable to employ the cathode electrolytic method to form the Zr film, the phosphoric acid film and the phenol resin film.
  • the tannin acid is added in the acid solution used in the digesting method and the cathode electrolysis method, the tannin acid is bonded to Fe, a tannin acid Fe film is formed on a surface, which results in enhancement of rust resistance and adhesion. Accordingly, depending on use, the films may be treated in the acid solution in which the tannin acid is added.
