Definitions

  • the invention relates to a process for the production of brown cover layers on copper-shaped semi-finished products, in particular on rolled strips and sheets for the roof covering and facade cladding.
  • the surface of bare metal has a firmly adhering and stable top layer made of copper oxide.
  • the initially very thin oxide film stabilizes the surface of the copper material noticeably against the effects of the atmosphere.
  • the slow development of the oxide layer as a result of the reaction of the copper with moisture and atmospheric oxygen ideally gradually produces a uniform brown color (brown patina), the surface of the copper increasingly losing its metallic luster.
  • the brown top layer gets darker over time and then changes to an anthracite brown. This is the final state that usually occurs on vertical building surfaces, such as external wall cladding.
  • the top layer changes color in reaction to the substances contained in the atmosphere, such as sulfur dioxide, carbon dioxide and chlorides, to give basic copper compounds until the copper-typical patina green is reached.
  • the formation of the brown cover layer can, however, under certain atmospheric conditions be considerably delayed in places but also accelerate, so that, as a rule, it is necessary to wait a relatively long time until a uniform discoloration of the copper surface is achieved. Deviations from a uniform color tone can be observed especially in the early stages of weathering. In many cases, uneven dark spots and / or stripes often form on the copper surface. However, as the weathering continues due to atmospheric influences, these color differences disappear.
  • a method for producing uniform layers of copper (I) oxide on the surface of copper wire or ribbon is mentioned, for example, in Chemical Abstracts, Volume 83, No. 2, July 1975, page 258, Summary No. 32184t.
  • the copper oxide layer is formed by an oxidizing heat treatment at a temperature in the temperature range from 300 to 1000 ° C.
  • the invention has for its object to provide a method with which a uniform and firmly adhering brown cover layer (brown patina) can be generated on the surface of copper-shaped semifinished product made of copper, which is not damaged even in the further processing necessary in particular in the construction sector or flakes off.
  • pre-patinated strips or sheets made of copper produced by the process according to the invention have cover layers which both have excellent adhesive strength and remain preform-resistant when bent or folded, i.e. H. show no detachment. Even the fingerprints that are often unavoidable when installing roof covers and facade cladding remain largely unremarkable on the pre-patinated surface.
  • a cold-rolled and possibly degreased band made of SF copper in accordance with DIN 1787 with a thickness of 0.6 mm and a width of 1000 mm was roughened uniformly by means of a grinding device.
  • the copper strip was then fed to a gas heated continuous furnace for heat treatment.
  • a controlled gas atmosphere with approximately 25% by volume oxygen was set in the furnace. After a short cooling distance, the pre-oxidized copper strip was then immersed at a working temperature of about 80 ° C.
