Definitions

  • the invention relates to a method for surface coating of molded wood parts.
  • Such molded wood parts with a wooden surface are used, for example, for the interior of motor vehicles.
  • the surface of such molded wood parts which can be designed as solid parts or as molded plywood parts, but which can also have a veneered surface, is provided with a transparent lacquer or another transparent surface coating material, so that on the one hand a possibly shiny and hard-wearing surface is created while, on the other hand, this transparent surface coating, which is usually referred to as transparent lacquering, not only keeps the structure of the wood visible, but also emphasizes it.
  • This object is achieved according to the invention in a method of the type described at the outset by placing the molded wood part to be coated on the surface in a cavity, the inner wall of which is at a small distance from the molded wood part in the region of the surface to be coated, and thus between the inner wall and the surface to be coated forms a gap, which extends over the entire surface to be coated and has a substantially constant thickness, so that the cavity is at least partially evacuated, that a liquid surface coating material is filled into the cavity during the evacuation or afterwards, and that afterwards complete filling of the gap, the liquid material hardens in the interior of the cavity.
  • the molded part In contrast to conventional surface coating techniques, in which the material is applied to the free surface, the molded part is here, as it were, embedded in the liquid coating material in a cavity, the coating material covering the gap between the surface to be coated and the inner wall of the cavity completely, so that the geometry of this gap corresponds to the geometry of the surface layer applied.
  • the evacuation By evacuating the cavity, care is taken In addition to the fact that no gas bubbles are embedded in the surface layer, the evacuation also leads to the fact that the filled liquid material pours completely uniformly into all remaining areas of the gap space and completely fills them completely homogeneously. This in turn ensures a homogeneous and uninterrupted quality of the surface coating.
  • This filling can be further improved by filling the liquid surface coating material into the cavity under increased pressure, that is to say practically pressing it into the gap space.
  • the filled, liquid surface material can be hardened in various ways; chemical or physical hardening processes are possible, for example by heating. It is particularly advantageous if, after the cavity has been filled, the liquid surface material through the radiation-permeable walls of the cavity is subjected to radiation which promotes the hardening of the liquid surface material, in particular if the radiation emits electromagnetic radiation in the UV range is. Molds with a cavity that are transparent to this radiation are then used, for example glass molds.
  • Synthetic resins based on polyurethane, polyester or acrylic can preferably be used as the liquid surface coating material.
  • the process can also be carried out particularly economically by removing the coated wooden molded part from the cavity after hardening and without further ado Surface processing leaves. This is possible in particular if the inner wall of the cavity is completely smooth, a high-gloss surface of the surface coating is then obtained.
  • a cavity with a structured inner wall so that a coating with a corresponding surface structure is achieved, for example a matt surface or a corrugated surface.
  • the shaped wood part is arranged in the cavity in such a way that a gap is formed on all sides between the surface of the shaped wood part and the inner wall of the cavity.
  • the shaped wooden part in another exemplary embodiment, however, it is also possible for the shaped wooden part to be directly and partially applied to the inner wall of the cavity, so that a gap is arranged between the surface to be coated and the inner wall of the cavity only in the other surface areas. In this way, coating can also be achieved in some areas. In many cases, it is sufficient for interior trim parts of motor vehicles, for example, if the surface facing the interior is appropriately coated; the rear side of such molded wood parts can remain essentially uncoated. Intermediate forms are of course also conceivable, the coating on the side facing outward being thicker than the coating on the opposite side. This can be achieved by a correspondingly asymmetrical arrangement of the molded wood part in the cavity.
  • the described invention of course extends not only to the method, but also to molded parts which are produced using this method.
  • Figure 1 a sectional view through a mold with a
  • Figure 2 is a sectional view taken along line 2-2 in Figure 1 and
  • FIG. 3 a view similar to FIG. 1 with a molded part lying flat on the inner wall of the cavity.
  • a shape 1 which surrounds a cavity 2 which is closed on all sides.
  • a molded part 3 is inserted into this cavity 2, for example a molded part made of solid wood or plywood or a pressed wood part with a veneered surface.
  • the shape of the cavity 2 is chosen so that it is adapted to the shape of the molded part 3.
  • the inner wall 4 of the cavity 2 surrounds the surface 5 of the molded part 3 on all sides at an equally large, overall small distance, so that between the surface 5 on the one hand and the inner wall 4 on the other hand a gap 3 surrounding the molded part 3 on all sides 6 is formed.
  • the thickness of the gap can be, for example, between 0.1 mm and 1.5 mm, depending on the desired thickness of the surface coating.
  • FIG. 1 and 2 The shape shown in Figures 1 and 2 is designed in two parts, so that the cavity 2 is accessible for inserting and removing the molded part 3 by separating the two parts.
  • This two-part design is shown only very schematically in the drawing, for example the dividing lines can also run parallel to the central plane of the molded part 3.
  • the cavity 2 is connected via a suction connection 8 to a suction source, not shown in the drawing, for example to a pump.
  • the suction connection 8 is preferably arranged at the lower end of the cavity 2.
  • a filling connection 9 which is connected to a storage container, opens into the cavity 2 which the surface coating material used is kept in liquid form.
  • It can be, for example, synthetic resins based on polyurethane, polyester-based or acrylic-based, which are preferably transparent.
  • liquid surface coating material is filled into the cavity 2 via the filling connection 9, preferably under increased pressure, for example with the aid of a feed pump. This liquid surface material fills the gap space 6 completely and homogeneously.
  • the liquid surface coating material is cured, for example by heating the mold or by irradiation, preferably with UV radiation.
  • molds are used whose material is transparent to the radiation used, for example molds made of glass, silicone or a transparent plastic. If other curing methods are used, the molds can also be made of steel, aluminum or non-transparent synthetic resins, for example.
  • the mold is opened, and the surface-coated molded part 3 can then be removed from the cavity.
  • post-processing of the surface is no longer necessary; if the inner wall 4 is of a suitable nature, the surface of the coated molded part can be used directly for the end product.
  • the inner wall 4 can be completely smooth, so that a high-gloss surface is obtained, but structuring is also possible, so that, for example, a matt surface or a corrugated surface is produced.
  • the gap space 6 surrounds the molded part 3 on all sides, so that there is an all-round surface coating.
  • the molded part in the exemplary embodiment in FIG. 3 is inserted into the cavity 2 in such a way that it lies flat against the inner wall 4 on one side and a gap space 6 is formed only on the opposite side. Otherwise the structure is the same.
  • the cavity 2 is filled with the liquid surface coating material, it only reaches the surface of the molded part on one side thereof, so that a one-sided surface coating is obtained. Otherwise the process is exactly the same.

Abstract

Afin de simplifier un procédé permettant de recouvrir la surface de pièces mises en forme, en bois massif ou en contreplaqué, et d'obtenir une surface de meilleure qualité, il est prévu d'introduire la pièce de bois (3) mise en forme dont la surface doit être recouverte, à plat dans un espace creux (2) dont la paroi intérieure présente un léger écart par rapport à la pièce de bois, dans la zone de la surface à recouvrir, ce qui crée, entre la paroi intérieure et la surface à recouvrir, une fente (6) de largeur sensiblement constante qui s'étend sur toute la surface à recouvrir. Il est prévu de faire le vide, au moins en partie, dans l'espace creux (2), de remplir ledit espace creux avec un matériau liquide de recouvrement de surface, pendant ou après l'opération de mise sous vide, et de faire durcir le matériau liquide à l'intérieur de l'espace creux, une fois la fente complètement remplie.
