Definitions

  • the invention relates to a method for finishing a carrier plate, in particular a wood or wood-based material board. Furthermore, the invention relates to a pressing device.
  • Such a method is for example from the EP 1 225 033 B1 known.
  • the plates produced by the process are used, for example, for furniture construction as a table top. From them also panels, in particular wall and floor panels can be produced.
  • Floor panels with a base plate made of wood material are commonly referred to as laminate panels and have been for many years for the substitution of parquet in the trade.
  • the surface of the support plate is first ground and then applied a primer of one or more melamine resin layers.
  • the desired decor parquet, wood grain, tiles, etc.
  • a functional layer is applied for sealing the top. If the carrier plate is then to be further processed to floor panels, wear-resistant particles, such as corundum, are embedded in the functional layer.
  • the layer structure is pressed and in the process a structure (relief) corresponding to the decor is embossed in order to match the visual and haptic impression with the natural material reproduced by the decor.
  • WO 2007/059805 A1 From the WO 2007/059805 A1 is a coating system with flowable coating material for smooth or textured surfaces known.
  • a material web with a structured surface is used.
  • a carrier material On the input side of the coating system, a carrier material is supplied, which is coated with a flowable material.
  • a collecting device Below the material web a collecting device is provided, which is funnel-shaped in cross section together with the material web, so that the flowable material can be applied to the carrier plate. While the carrier plate is transported with the overlying web through the device, the coating material hardens and it forms in its surface, the predetermined structure of the material web.
  • the pressing device is very complex. As a coating material expensive UV coatings must be used.
  • a hot press for surface hardening of wood-based panels known.
  • one or more synthetic resin such as melamine resin precondensates containing films are applied to the support plate one or both sides and then pressed in the hot press. The resin cures and the film bonds firmly to the carrier plate.
  • Paper webs can be laid over the press plates, by means of which the structure of the paper webs can be transferred to the surface during the pressing of the wood-based board.
  • the surface applied to the top of the support plate adhesive can be rolled, brushed or sprayed. After drying, the non-resin decorative paper is then applied by unwinding from a roll. Subsequently, the decor paper is pressed under the action of pressure and / or temperature with the large-sized carrier plate. At least one functional layer of melamine-based resin is then applied as a seal on top of the decorative paper laminated with the carrier plate.
  • the surface created in this way is characterized by a new visual and haptic impression.
  • the product surfaces are softer or velvety, which is due to the effect of the structurizer film instead of a hard steel pressed sheet. Since the structure is carried out in a short-cycle press by means of the structuring sensor film, the desired structure can be quickly and inexpensively changed or replaced. So it can be made on a pressing device a wide range of products.
  • a counteracting layer is preferably applied to the underside prior to pressing.
  • the primer is preferably applied liquid in a direct coating plant.
  • the primer is preferably applied to the ground surface of the top of the carrier plate. As a result, a very smooth surface is achieved and a sharp structuring possible, which improves the visual and haptic impression of the finished finished carrier plate.
  • the laminated with the decor paper backing plate is fed as a prefabricated intermediate for liquid coating a direct coating plant.
  • the plate is then fed to a pressing device, preferably a KT press (short-cycle press).
  • a pressing device for pressing and structuring carrier plate provided with a plurality of resin layers, having an upper pressing plate and a lower pressing plate, in which a patterning foil provided with depressions and / or elevations is arranged below the upper pressing plate is characterized in that the upper pressure plate (1) has a pressure plate (4) provided with a plurality of openings and the openings are in communication with a pneumatic device (50) and in that the pneumatic device (50) has an overpressure for blowing off the structure foil (8) from the press plate (4) / the press plate (1) can be generated.
  • the pneumatic device In order to remove the shear modifier foil which bears against the press plate, the pneumatic device preferably generates an overpressure in a pulse-like manner, which blows off the texturizer foil from the press plate.
  • the texturizer film is preferably applied to the press plate.
  • it is preferably fixable to the pressing plate, which can be done for example by suction, electrostatic charging or adhesion.
  • the texturing film is inexpensive to produce compared to a press plate. Although their wear behavior lags behind that of a press plate, their use is still more economical.
  • the press can be converted quickly if the structure is to be changed because the decorative paper has been changed.
  • decorsynchronous structures are easier to set up. Due to the fast change of decor paper and associated shear foil, a high quality and wide range of products can be produced.
  • an unwinding device is arranged on one side next to the upper press plate, and a winding device for the texturing film is arranged on the opposite side.
  • the structure matching the printed decor is embossed in each case in the associated plate size.
  • the structure can be repeated on the foil tape.
  • a negative pressure for sucking the pattern generator film can be generated.
  • the structurizer film covers the
  • the short-cycle press allows integrated flow production to be realized.
  • FIG. 2 schematically shows the side view of a short-cycle press 60 (KT press) with the upper pressure plate 1 and the lower pressure plate 11.
  • the upper pressure plate 1 consists of the upper frame 2, the press pad 3 and the press plate 4.
  • the arranged on a press table 12 lower Press plate 11 consists of the base 13, the press pad 14 and the press plate 15th
  • the lower press plate 11 is rigid. About the impression cylinder 5, the upper pressure plate 1 can be lowered to the lower pressure plate 11 and pressurized.
  • the press plates 1, 11 are heated by thermal oil in a known manner.
  • the openings in the press plate 4 are connected to a both negative pressure and positive pressure generating pneumatic device 50 in connection.
  • an unwinding device 6 and a winding device 10 are arranged opposite one another.
  • the structuring film 8 is unwound from the unwinding device 6 and wound up at the same time by the winding device 10.
  • the pattern generator film is guided below the press plate 1.
  • the pneumatic device 50 When the pneumatic device 50 generates negative pressure, the structuring film 9 is sucked onto the press plate 4. To release a pneumatic blast is generated via the pneumatic device 50, which blows the structure-sensor film 8 from the press plate 4.
  • the large-sized support plate 100 for example, an MDF or HDF plate, be abraded by 0.1 mm.
  • melamine-based or urea-based liquid resin or a mixture of both may be applied to the top for priming and dried to the layer 101.
  • a non-resin decorative paper 102 is placed by this is unwound from a roll 32. This is done in a known laminating device 30, in which the applied decorative paper 102 is then laminated with the carrier plate 100.
  • a direct coating system 40 into which the laminated carrier plate is introduced as a prefabricated intermediate product, at least one functional layer 103 is applied as a seal of the upper side.
  • the functional layer 103 which consists of a melamine-based synthetic resin, the abrasion and / or the scratch-resistance-increasing particles can be integrated.
  • the functional layer 103 can also be formed antistatic.
  • At least one counter-tensile layer 104 is applied to its underside and dried. Subsequently, the carrier plate 100 is transported into the short-cycle press 60 and placed on the lower press plate 11. The structure of the patterning film 8 corresponding to the decor of the decor paper 102 is selected and then pulled under the upper press plate 1 by driving the take-up device 10. In this case, the structure sensor film 8 is wound from the unwinding device 6. The structuring film 8 is sucked onto the press plate 4 and then the upper press plate 1 is lowered onto the carrier plate 100.
  • the resin layers melt and the liquid resin runs into the depressions or fills the gaps between the elevations of the structuring film 8, so that after curing of the resin, a structure corresponding to the decoration in the surface of the Carrier plate 100 was generated.
  • the decorative paper 102 can directly on the top of the support plate 100th be laminated on.
  • an adhesive 105 is first rolled in the laminating device 30 with a roller 31.
  • the adhesive 105 used are conventional glues or adhesives, in any case those which are subsequently compressible with further layers on the KT press 60.
