Definitions

  • the present invention relates to a process for coating an aluminum alloy substrate with a polymer. More particularly, the invention relates to a process for pretreating an aluminum alloy substrate with a vinyl phosphonic acid-acrylic acid copolymer before polymer coating the substrate.
  • chemical conversion coatings have been formed on aluminum alloys by "converting" a surface of the metal into a tightly adherent coating, part of which consists of an oxidized form of aluminum. Chemical conversion coatings provide high corrosion resistance and improved adhesion for polymer coatings.
  • a chromium-phosphate conversion coating is typically provided by contacting aluminum with an aqueous solution containing hexavalent chromium ions, phosphate ions and fluoride ions.
  • concerns have arisen regarding the pollution effects of chromates and phosphates discharged into waterways by such processes. Because of the high solubility and strongly oxidizing character of hexavalent chromium ions, expensive waste treatment procedures must be employed to reduce the hexavalent chromium ions to trivalent chromium ions for waste disposal.
  • chromate-free conversion coatings for aluminum.
  • some chromate-free conversion coatings contain zirconium, titanium, hafnium and/or silicon, sometimes combined with fluorides, surfactants and polymers such as polyacrylic acid.
  • non-chromate conversion coating or primer for improving the adhesion and corrosion resistance of polymer coated aluminum alloy substrates.
  • Polymer adhesion and corrosion resistance are important characteristics in aluminum alloy sheet used for making food container bodies and ends and beverage container ends. Attempts have also been made in the prior art to pretreat substrates with various organophosphorus compounds before coating them with a polymer.
  • organophosphorus compounds includes organophosphoric acids, organophosphinic acids, organophosphonic acids, as well as various salts, esters, partial salts, and partial esters of such acids.
  • Dutch Patent Application No. 263,668, filed April 14, 1961 discloses a process wherein steel sheets are treated with a vinylphosphonic acid/acrylic acid copolymer before coating with an alkyd resin enamel.
  • organophosphorus pretreatments may perform adequately, they are expensive to implement. Accordingly, there still remains a need to provide an efficient and economical process for pretreating an aluminum alloy substrate with an organophosphorus compound before applying a polymer coating.

Before working, the ingot or billet is subjected to elevated temperature homogenization. The alloy stock is then hot rolled to provide an intermediate gauge sheet.
  • the material may be hot rolled at a metal entry temperature of about 700°-975°F to provide an intermediate product having a thickness of about 0.100 inch to 0.150 inch.
  • This material is cold rolled to provide a sheet ranging in thickness from about 0.006 to 0.015 inch.

  • the intermediate gauge product is annealed, followed by hot rolling and then cold rolling to a final gauge product having a thickness of about 0.006 to 0.015 inch.
  • the sheet is coated with a polymer and then drawn and redrawn into food container bodies.
  • the natural oxide coating on an aluminum alloy sheet surface is generally sufficient for practice of our invention.
  • the natural oxide coating ordinarily has a thickness of approximately 30-50 angstroms.
  • the oxide coating can be grown by treatments such as anodic oxidation or hydrothermal treatment in water, water vapor or aqueous solutions.
  • Aluminum alloy sheet of the invention is generally cleaned with an alkaline surface cleaner to remove any residual lubricant adhering to the surface, and then rinsed with water. Cleaning can be avoided if the residual lubricant content is negligible.
