Definitions

  • the invention relates to a method for embossing the surface of a wood-based panel, a device for embossing and a wood-based panel with embossed surface.
  • Wood-based panels are often provided with decorative surfaces, usually with the reproduction of natural materials, especially wood or stone surfaces.
  • the surface is first primed and painted, or decorative paper is applied.
  • a resin e.g., an overlay
  • varnish seal is applied to render the surface useful.
  • a matching to the respective color design structure is applied, for. B. by embossing or pressing the finished coated wood-based panel.
  • profiled press plates are used to create pores for a wood decor. The subsequently applied pores should match the previously created by color or decorative paper design.
  • the DE 10 2006 007 976 describes a similar process.
  • This method is First pressed by means of a press a relief in the surface of up to 150 ° C heated plate. Then a decor and a seal is applied and cured.
  • the CH 614 666 Describes a method of deforming the plate surface in which a previously moistened wood-based panel is deformed under low pressure and low temperature. The process is not economical by wetting the surface.
  • the DE 2711197 discloses a method in which a wood-based panel or plywood panel is embossed by the action of temperature (T> 200 ° C) and pressure and simultaneously discolored. Here you work with a stamping plate.
  • US2695857 shows a stamping process for plywood boards passing between a heated embossing roll (T> 200 ° C) and a counter-pressure roller.
  • T> 200 ° C the already preheated MDF board is provided with a surface structure by means of a press belt.
  • discoloration Neither the first nor the latter publication disclose the applied pressing pressure.
  • the WO2007 / 061193 shows an embossing process in which wood-based panels with a heated embossing roller (T ⁇ 200 ° C) are structured, for example, a pressure of 5 bar is applied, but in any case less than 10 bar. There is no discoloration. It is an object of the invention to provide a method and an apparatus for producing decorsynchronous embossed wood-based panels.
  • the object underlying the invention is achieved by a method according to claim 1, with a device according to claim 9.
  • the inventive method for producing a decoration on the surface of a wood-based panel in the color and profile of the surface are synchronous provides that the wood-based panel between a profiled decorating roller and a counter-pressure roller is passed therethrough.
  • the decorative roller is heated to a temperature of more than 200 ° C, preferably up to 500 ° C.
  • a pressure of at least 10 bar to a maximum of 300 bar is exerted on the decorating roller or a nip is set between the decorating roller and the counterpressure roller, which is narrower than the thickness of the wood-based material board to be embossed up to 2 mm.
  • very natural wood decors can be produced by this method, since the color of the embossed wood material surface of the coloring of wood exactly matches.
  • the coloring also coincides with the embossing structure completely, because the discoloration of the surface of the wood material exactly the color of e.g. of wood simulates.
  • a colored relief a decoration is produced on the surface of the wood-based panel.
  • the pressure exerted on the decorating roller typically by means of a press hydraulics
  • the pressure is chosen within a range of 10 bar to a maximum of 300 bar, depending on the working temperature (between 200 ° C and 500 ° C), of the desired decor or decor depth and of the respective wood-based material.
  • the coloring and embossing of the surface of the wood-based panel is produced by setting a nip between the decorative wood and the counter-pressure roller that is at least 0.1 mm, and not more than 2 mm smaller than the thickness of the wood-based panel to be embossed, then the adjustment of the nip also takes place Dependence on the working temperature, on the type, in particular the embossing depth of the decoration and the material of the wood-based panel.
  • wood-based panels very advantageously allow without additional use of color or additional coloring of the surface or the plate generating the typical for numerous wood structures color scale of bright natural tones over the entire scale of browns to almost black colors.
  • the surface of the untreated or possibly colored wood-based panel is embossed.
  • the desired color effect is only achieved when the heated decor roller on wood and / or chips or fibers, including paper fibers, meets. Only after the embossing or decoration can then be applied a seal.
  • Embossed resin layer the advantages of the invention are not achieved. Through a synthetic resin layer color and embossing effects can not be generated synchronously.
  • the invention thus makes it possible to achieve a complete decoration in which color design and embossing are completed in a single operation. That saves time and money.
  • the minimum temperature of 200 ° C results from the fact that below this temperature no color effects are generated.
  • the maximum temperature of 500 ° C results from the fact that either the energy consumption is not economically feasible, or that the color effects are no longer precisely controlled, z. B. because it comes despite the short exposure time to a decomposition of the fibers.
  • the optimum process temperature on the one hand, it has to be considered which color scheme and which embossing, in particular which embossing depth, the décor requires.
  • the roller pressure or nip, the wood-based material and the production speed must be compared with the process temperature. The temperature in particular affects coloration and plasticization.

  • the process according to the invention can preferably be carried out if a pressure of up to 30 bar, preferably of up to 50 bar, advantageously of up to 100 bar, is also exerted on the decor roller. If necessary, z. B. to achieve a particularly deep character, the pressure can be increased. Upper limit is usually the pressure of 300 bar. If you want to work with further increased pressure, special measures with special costs are required to provide appropriate hydraulics. This is usually uneconomical.
  • Pressure and temperature are high in the inventive method, in particular the temperature is significantly higher than in known methods. However, since rolling is done in a continuous process, the high pressure and temperature do not have a detrimental effect on the wood-based panel.
  • the decorative roller but also the counter-pressure roller is heated during embossing. This prevents unwanted deformation of the plate. In addition, it can thus be produced on opposite surfaces of the wood-based panel embossing. If desired, opposite surfaces of the wood-based panel can be provided with the same or different embossing or decors in a single operation. Further measures on the device for embossing are usually not required, at best, it must be ensured that pressure is uniformly transmitted to the surface of the plate via both rollers.
  • the surface to be embossed is heated prior to embossing the surface of a wood-based panel according to the invention.
  • the heating can be done directly or indirectly as explained below.
  • an improved embossing profile can be achieved, but above all, the production speed can be increased because deformation and discoloration of the surface of the wood-based panel are greatly determined by the heat transfer and the temperature at the contact surface between decor roller and surface to be embossed.
  • a heating of the surface to 40 ° C already has an advantageous effect, it is advantageous to heat the surface to be embossed to 150 ° C or 200 ° C up to 100 ° C, depending on the material of the plate and to be generated decor. The heating takes place z. B. with high frequency heaters.
  • a significantly wider range of surface designs can be achieved by the invention
  • Process are prepared when the surface to be embossed is colored before embossing.
  • stone and fantasy decors can be produced in this way on a large scale and with great diversity. It has been found that the dyeing of the surface or the dyeing of a plate does not altogether oppose the stamping according to the invention, because even with a colored surface of the wood-based material surface the direct contact with the fiber is given so that the deformation takes place as intended. This also contributes to the fact that dyes other than z.
  • B. Kunststoffharze- the heat transfer does not hinder. Although some dyes change the hue at the occurring during embossing, high temperatures. However, this can be taken into account in the development of the decor and also be used to advantage.
  • a decor can be designed later by applying color.
  • the applied decor can be wholly or partially supplemented or changed.
  • An inkjet printer is suitable here because, if necessary, the entire profile, even at a profile depth of e.g. 1 mm, can be processed. Alternatively, especially when new parts of the decor are to be processed or changed, it is also possible to use rollers or other inking devices.
  • the wood-based panel produced according to the invention with embossed surface is not yet ready for use for most applications. It is therefore provided according to a preferred embodiment of the method according to the invention with a coating on the embossed surface.
