Definitions

  • the invention relates to a method for producing a partially coated pane, the pane produced by the method and its use.
  • the glass pane is coated with the atoms released from the target in an evacuated chamber.
  • the atoms move, guided by electric fields, through the chamber towards the glass pane. So they move from the cathode, on which the target is arranged, towards the anode. Due to the arrangement of the glass pane between the cathode and the anode, layers form on the glass pane.
  • magnetron sputtering an additional magnetic field is arranged behind the cathode, which leads to faster layer growth and a denser, i.e. less porous, layer.
  • Methods in which sputtering is used to coat glass panes are known, for example, from WO 9900528A1, DE 69625403T2, EP 0844507A1, DE 10126868C1 and WO 2017198363A1.
  • the object of the present invention is to provide an improved method for producing a pane with a metallic coating applied in certain areas to provide.
  • the production should largely do without the step of masking the pane.
  • a transparent sheet of glass having an outer surface and an inner surface is provided and
  • the metallic coating can be applied very precisely to just one area of the glass pane. Therefore, in order to coat only the areas of the glass pane intended for this purpose, in contrast to conventional methods for coating glass panes, only little or no masking of the glass pane is necessary.
  • Conventional processes for coating glass panes mean, for example, magnetron sputtering in conjunction with physical gas deposition. In this standard procedure, the glass pane must be masked in the areas that are not to be coated before the procedure is carried out. This masking represents a great effort, which can be reduced or avoided by coating using cold glass spraying. In addition to this great advantage of the invention, material can also be saved through the targeted application of the metallic coating by means of cold glass spraying.
  • the glass pane includes a peripheral edge, which preferably includes two side edges, a top edge and a bottom edge.
  • the glass pane is intended to separate an interior space from an external environment, whether taken alone or as part of a laminated pane or an insulating glass pane.
  • the inner surface of the glass pane is intended to face the interior; the outer surface of the glass pane is intended to face the outside environment.
  • Cold gas spraying is a coating process well known to those skilled in the art, in which a metallic powder is applied to a carrier at very high speed. Coating by means of cold gas spraying is known, for example, from WO 2010003396A1, EP 3845685A1 and EP 2902530A1.
  • a pressurized gas is heated to 300°C or more, more preferably 500°C or more, particularly not more than 1000°C in a heater.
  • a metallic powder is injected to the gas in the Laval nozzle, whereby the particles of the metallic powder are accelerated to a speed of at least 800 m/s, more preferably at least 1000 m/s and in particular at least 1200 m/s.
  • the gas cools down to up to 200.degree. C., particularly preferably to up to 150.degree. C. and in particular to up to 100.degree.
  • the gas is preferably 90% or more and more preferably 99% or more helium or nitrogen.
  • the average particle diameter of the metallic powders is preferably from 5 ⁇ m to 50 ⁇ m.
  • pressurized gas means that the gas pressure is at least 150 bar, particularly preferably at least 170 bar and in particular at least 200 bar.
  • the flow rate with which a surface can be coated is preferably at least 2 m 3 min -1 and in particular at least 2.5 m 3 min -1 .
  • pressurized gas means that the gas pressure is at most 150 bar, preferably at most 100 bar and in particular at least 50 bar.
  • the flow rate at which a surface can be coated is preferably from 0.5 m 3 min -1 per to 2 m 3 min -1 .
  • High-pressure cold gas spraying is particularly advantageous when the applied coating is purely metallic, whereas low-pressure cold gas spraying can be carried out with lower energy consumption.
  • the metallic coating Due to the high speed at which the particles hit the inner surface or the outer surface of the glass pane, an adhesive bond is formed between the metal and the glass pane without the metallic coating being oxidized in the process. Due to the moderate temperatures with which the glass pane is coated, the metallic coating has a homogeneous layer thickness.
  • the metallic coating is applied to an area of the inner surface of the glass pane which—when viewed through the glass pane—is at least partially covered by the first masking print and preferably completely covered by the first masking print.
  • the masking print is preferably applied in a frame-like manner along the peripheral edge of the glass pane.
  • the masking print preferably has a greater width in the area of overlap with the metallic coating.
  • “width” means the width perpendicular to the extension. This arrangement is particularly advantageous when the glass pane is used as part of a projection arrangement. Due to the first masking print, no light escapes from the interior to the outside and the contrast of a virtual image, which is reflected on the metallic coating, is increased in the areas of overlap with the first masking print.
  • the metallic coating is a coating containing a thin layer stack, ie a layer sequence of thin individual layers.
  • This thin layer stack contains one or more electrically conductive layers based on nickel, titanium and/or aluminum.
  • the electrically conductive layer based on nickel, titanium and/or aluminum gives the metallic coating basic reflective properties and also an IR-reflective effect and electrical conductivity.
  • the electrically conductive layer is based on nickel, titanium and/or aluminum.
  • the conductive layer preferably contains at least 90% by weight nickel, titanium and/or aluminum, particularly preferably at least 99% by weight aluminum, very particularly preferably at least 99.9% by weight nickel, titanium and/or aluminum.
  • the first masking print is applied to the inner surface or the outer surface of the glass pane and the second masking print is applied to the inner surface or the outer surface of the further glass pane.
  • At least the first or the second masking print is preferably applied in such a way that, according to the method according to the invention, it covers the pane with the metallic coating when viewed through it.
  • the first masking pressure and/or the second masking pressure preferably extends over less than 30%, particularly preferably over less than 25% and in particular over less than 20% of the main surface of the laminated pane.
  • the opaque film or the opaque area is arranged in a peripheral frame-like manner in an edge area of the laminated pane and has a greater width in particular in a section that overlaps the metallic coating than in sections that differ from it.
  • the opaque frame formed by the opaque film is preferably the arranged transparent film. The opaque film is thus arranged around the transparent film in a manner similar to a pass-partout.
  • “transparent” means that the total transmission of the composite pane corresponds to the legal provisions for windshields and for visible light preferably a transmission (according to ISO 9050:2003) of more than 30% and in particular of more than 60%, for example more than 70%.
  • “opaque” means a light transmission of less than 15%, preferably less than 10%, particularly preferably less than 5% and in particular 0%.
  • a transparent glass pane with an outer surface and an inner surface is provided.
  • a protective layer is applied to the metallic coating, the preferred order is:
  • a further transparent glass pane which has an outer surface and an inner surface, and a thermoplastic intermediate layer are provided.
  • a transparent glass pane with an outer surface and an inner surface is provided.
  • a metallic coating is applied to an area of the outer surface or the inner surface of the glass pane by means of cold gas spraying.
  • a further transparent glass pane which has an outer surface and an inner surface, and a thermoplastic intermediate layer are provided.
  • a metallic coating is applied to an area of the inner surface of the glass pane by means of cold gas spraying.

  • a further transparent glass pane which has an outer surface and an inner surface, and a thermoplastic intermediate layer are provided.
  • a protective layer is applied to the metallic coating.
  • Process step (D) can also be carried out before process step (A) or simultaneously with process step (A), the sequence of the remaining process steps otherwise remaining the same.
  • process step (B) is carried out automatically.
  • the Laval nozzle is preferably guided along the area to be coated using a suitable holder.
  • the Laval nozzle automatically emits the spray jet for coating the glass pane.
  • the glass pane to be coated can be transported to the Laval nozzle by means of a conveyor belt, with a glass pane that has already been coated being able to be transported away by means of the conveyor belt.
  • the Laval nozzle is preferably connected to a control unit which electronically instructs the Laval nozzle to coat the areas of the glass pane to be coated.
  • the automation is to be designed in such a way that the method step or steps can be carried out as intended in whole or in part, preferably entirely, without the involvement of a human being.
  • process steps (A) and (B) and optionally (C) and/or (D) and/or (F) and/or (E) are carried out automatically.
  • the full automation of the process increases the throughput and production volume of the process, relieves people of physical and monotonous work, improves production quality and can reduce defective production.
