Definitions
- the invention relates to a method for producing a structure, in particular a wooden structure, on the surface of fiberboard, in particular medium-density fiberboard, by applying a substance to the surface of a hardened fiberboard as the starting material and then applying the fiberboard with the substance in a short-cycle press of pressure and heat and using a structured press plate.
- a structured press plate It is known to equip or equip fiberboard in the surface so that the surface does not appear as a flat surface, but has a certain structure, which can have very different shapes depending on the requirements.
- Such structured surfaces are particularly needed in furniture manufacturing. For example, in the production of kitchen fronts, but also in the carcass area, fiberboard and other panels made of wood material can be used where a relief-like, structured surface is desired.
- the present invention is concerned with the attachment of a structure to the surface of a fiberboard which has already hardened and which has therefore already gone through the usual manufacturing process.
- melamine-resin-coated papers are placed on the fiberboard, particle board and the like after they have hardened and the plate is pressed as a starting material with the melamine-resin-coated paper in a short-cycle press.
- a short-cycle press is understood to be a known type of press with which pressures of up to about 27 kp / qcm and temperature applications of up to about 180 ° C. are usually used.
- a structured press plate is placed on the paper layer and this results in an impression of the structure of the press plate in the area of the paper, that is to say on the surface of the fiberboard. If smooth press plates are used this results high-gloss flat surfaces.
- the structure practically only covers the surface in the melamine-resin-coated paper, which is placed on the starting material as a substance.
- the actual surface of the fiberboard is only slightly or hardly deformed. To this extent, this structure is created on the surface of the fiberboard.
- the advantage of this known method is that the surface of the fiberboard is given some protection by the melamine paper. By curing the melamine resin, the surface of the paper is sealed or closed, as it were.
- the known method is comparatively inexpensive to carry out, so that it can compete with a coating application in terms of effort.
- the decorative structures that can be produced are disadvantageously satisfactory only for subordinate claims.
- the paper surface usually remains recognizable, so that the structure of natural wood, for example, cannot be produced in this way or can only be produced very incompletely. For this reason, this process is used to refine such surfaces of fiberboard, which are mostly used only in the body area of furniture, but not in the front area.
- a hardened particle board is used as the starting material, which is particularly soft.
- This hardened chipboard is pressed and crushed in its surface by applying pressure and heat, whereby macro structures, that is, circumferential grooves, grooves, reliefs and. Like. Can be stamped into the surface. Temperatures of up to about 180 ° C are used. The depth of the embossed grooves can be up to 8 mm. Films and papers can also be melted onto the surface. Subsequent paint treatment of such deformed surfaces is also possible afterwards.
- a milling process for producing the relief is advantageous with this known method avoided, although a similar optical effect occurs. Disadvantageously, presses must be available for this process, the working pressures of which are very high.
- the method is only suitable and applicable for certain particularly soft wood chipboards.
- the invention is based on the object of demonstrating a method with which it is possible, using known systems, in particular short-cycle presses, to introduce a structure, in particular a wooden structure, directly into the surface of a fiberboard, in particular a medium-density fiberboard.
- a resin-water mixture is used as the substance. It is no longer a melamine-resin-coated paper that is applied to the surface of the fiberboard, but a resin-water mixture.
- This resin-water mixture softens penetrates into the surface of the fully cured fiberboard, so that the structure of the press plate can be molded in this surface during the subsequent pressing in the short-cycle press.
- the resin portion of the resin-water mixture hardens while the water portion evaporates. This means that the structure is applied in the surface and not only on the surface or on the surface, which is fundamental for a better decorative appearance.
- the surface of the fiberboard is immediately deformed because the structure is stamped into it. A disruptive layer of paper or a film on the surface is eliminated.
- Such disruptive media such as in particular papers, films and. The like. are saved, which also means a reduction in the cost of the manufacturing process.
- Another advantage lies in the fact that the tools for the further processing of the plates finished in this way in the surface become blunt less quickly and therefore result in a longer service life.
- edge milling Surfaces that were produced using a melamine-resin-coated paper are known to dull the cutters very quickly at the point at which the paper has to be removed by the milling process.
- milling is carried out directly in the material of the fiberboard, so that tears at the transition between fiberboard and paper, as occur in the prior art, are avoided.
- Melamine can advantageously be used as the resin within the resin / water mixture. This sets in Particle board and fibreboard industry is common resin, which is not only inexpensive, but with which the users already have the appropriate experience. Of course, other resins are also suitable.
- the resin-water mixture can be used in a proportion of 25 to 50%, in particular 30% resin, i. H.
- 30% is resin and 70% water. From this ratio it can be seen how important the presence of water is, which changes to the vapor state due to the application of pressure and heat during the pressing. This steam also penetrates to a certain depth into the surface of the fiberboard, making it soft and deformable so that the structures of the press plates can be reproduced accordingly.
- Structured press plates with a roughness depth of in a range from 100 to 200 » in particular approximately 180 » are advantageously used. These structures are therefore deeper than the structures used in connection with melamine-coated papers. Of course, the depth of the structure depends on the desired effect. However, structures of natural wood can be produced very well with the specified limits.
