Definitions

  • the invention relates to a multilayer film for applying a metal layer or a decorative layer to a workpiece, and to a method for applying a metal layer or decorative layer to a workpiece, and also to a method for producing a multilayer film.
  • profiles are often coated.
  • These workpieces (profiles) can be made of plastic or wood, for example.
  • the invention has for its object to provide a multilayer film, with the help of which in particular a workpiece of the type mentioned above with a metal layer or a decorative layer is to be coated so that a very long stable life of the coating is achieved.
  • the invention is intended to provide methods with which, in particular, a workpiece of the abovementioned type is to be coated with a metal layer or a decorative layer such that a stable and long service life of the coating is achieved.
  • the invention is intended to show a method for producing a film of the abovementioned type, which enables a coating of a workpiece with a long, stable service life.
  • the industry has developed a so-called wet / warm test, which subjects the coated workpiece for at least 500 hours special loads in changing humid-warm atmosphere and checks whether while aging phenomena occur.
  • the invention with its various configurations with regard to the film and the method, makes it possible to pass such a test for coated workpieces.
  • a multilayer film according to the invention is described with its preferred embodiments in claims 1 to 10.
  • release in this context means that a support is designed or prepared on its surface in such a way that under certain conditions (in particular temperatures) it deposits layers applied to another substrate, the other substrate usually being a coating to be coated or workpiece to be decorated, for example, a profile for a window or the like.
  • metal layers, color decals or lacquers applied to a support with "release” properties can under certain conditions be “peeled off” from this support and transferred to another substrate.
  • the WO 2010/028857 describes for this purpose a detaching roller which is heated from the outside with infrared radiators.
  • the EP 2 163 397 A1 shows a heated with hot oil heating roller.
  • Decor carrier and films that are preferably activated with the roller described here, are also in the WO 2008/116484 A1 described. There, a heating roller is heated with oil and in the feed direction of the decor carrier or the film, the heat roller is followed by a detaching roller.
  • the EP 1 795 345 A1 describes a device with a roller for heating (“heating cylinder"), with which a release film is heated.
  • a film F according to Fig. 1 consists of four layers.
  • the film F and its individual layers are each suitable for the release process.
  • an adhesive layer TPU is applied in particular thermoplastic polyurethane.
  • an adhesive layer may be extruded onto a polyethylene film of, for example, 35 ⁇ m thickness.
  • a further two-ply film is produced, in which a metal layer Al is applied to a cover layer PET, in particular polyethylene terephthalate.
  • the metal layer Al is preferably an aluminum layer.
  • the decorative layer D may be a printed layer of polypropylene or polyester.
  • Fig. 2 shows the application of a metal layer Al on a workpiece W of the type described above.
  • the workpiece W moves according to the arrow.
  • the rollers shown rotate according to the rotation arrows.
  • the cover layer PET is withdrawn (not shown).
  • the result is a three-layer film PE / TPU / Al.
  • This three-ply film is on a roll 10 according to Fig. 2 wound up and is unwound there in the direction of the rollers 12, 14.
  • the carrier layer PE is peeled off from this three-ply film in the release process and wound onto the roller 14. It remains on the roller 12, the two-layer film AI / TPU.
  • This two-ply film is according to Fig. 2 transferred via the pressure roller 12 so on the moving workpiece W that the adhesive layer TPU between the metal layer Al and the workpiece is located.
  • the metal layer Al may be replaced by a decorative layer D of the type described above. Otherwise, the film features and process characteristics are the same.
