Definitions

  • the present invention relates to a method for manufacturing a trim element, in particular a trim element which is used as a vehicle interior lining element.
  • a trim element which is used as a vehicle interior lining element.
  • Such interior lining elements can be lining elements for the center console or the doors or trim elements in the dashboard of the vehicle.
  • Trim elements for automotive interior are nowadays produced, in particular, in that a decorative layer which completely or partially forms the face side surface of the trim element is back injection molded with a reinforcement layer and provided on the face side with a transparent coating.
  • a decorative layer which completely or partially forms the face side surface of the trim element is back injection molded with a reinforcement layer and provided on the face side with a transparent coating.
  • Such a method is known from DE 41 24 297 A1.
  • With regard to good mechanical coupling of the rear side injection mold to the decorative layer it is also known to provide this decorative layer with a lamination.
  • the lamination is typically applied to the decorative layer before the decorative layer is injection mold coated.
  • a method for producing a trim element is known from DE 10 2008 009 766 A1, in which an upper and a lower nonwoven lamination are laminated onto a material layer.
  • a precious wood veneer is bonded on the upper side of the material layer to the lamination.
  • the material forming the upper lamination layer has a lower activation temperature than the lamination material on the underside.
  • the multi-layer structure is then placed in an injection mold and back injection molded to form a reinforcement layer.
  • the temperatures and pressures acting there are there considerably higher than the conditions for activating the lamination provided on the upper side.
  • the lamination on the underside is then fully activated and the upper lamination layer provided on the oppositely disposed side has fully set, which allows the precious wood veneer to glide and thereby perform a slight relative motion relative to the material layer before and during the injection molding due to the incomplete setting and thus prevent damage to the precious wood veneer during the back injection molding.
  • the lamination can be formed by combining a nonwoven material with adhesive.
  • the lamination can be, for example, nonwoven fabric having adhesive applied on both sides.
  • Such laminations are typically applied to the decorative layer by flatbed lamination.
  • the lamination is there applied on a flat table.
  • the decorative layer is placed onto the lamination.
  • the lamination and the layer are bonded to each other subject to the application of pressure and temperature by a die driven against the table.
  • the film of adhesive can be formed on the basis of phenol, melamine, acrylic, polyurethane or their combinations.
  • Such laminations are known and common, in particular, in the furniture industry.
  • the film of adhesive is crosslinked by applying pressure and temperature. It bonds accordingly with the layer.
  • An alternative lamination is formed by a mono-ply or multi-ply plastic film.
  • a plastic film is usually calendered on.
  • a multi-ply film is typically employed when, firstly, the lamination is to be adapted for the best possible adhesion to the layer and for the best possible adhesion to a layer placed thereagainst, for example, the rear side reinforcement layer.
  • one ply has particularly good adhesion properties to the first layer and the other ply particularly good adhesion properties to the second layer.
  • the lamination takes place by applying pressure and heat. The heat causes the plastic material of the film to at least flow, the film is possibly melted, whereby the adhesion with the layer(s) is improved.
  • the present invention is based on the problem of specifying a cost-effective and resource-saving method for manufacturing a trim element with multiple layers.
  • a method having the features of an embodiment is proposed for this according to the invention.
  • the first layer is bonded subject to the application of pressure and heat to a first lamination in a first lamination step.
  • a second layer is bonded under pressure and heat to a second lamination in a second, subsequent lamination step.
  • the heat introduced in the second lamination step also acts in the first lamination.
  • the effect of the heat introduced in the second lamination step into the first lamination is such that improved adhesive bonding between the first lamination and the first layer is obtained.
  • the first lamination step for bonding the first lamination to the first layer is typically carried out in such a way that the composite thus produced is still incomplete. Energy in the form of pressure or temperature is introduced only insufficiently during the first lamination step, whereby resources can be saved in this first lamination step.
  • this bonding agent is only slightly crosslinked or partially crosslinked in the first lamination step.
  • the maximum degree of crosslinking for an activatable lamination after the first lamination step is usually less than 50 percent.
  • the composite force between the first layer and the first lamination is increased.
  • crosslinking bonding agent being part of the first lamination
  • further possibly complete crosslinking is obtained also in the first lamination due to the heat introduced in the second lamination step.
  • the adhesion of the first lamination to the first layer after the second lamination step has a better quality than after the first lamination step.
  • a bonding agent formed as thermoplastic material which is bonded to the first layer. Due to the heat introduced, the second lamination step causes adhesion with improved quality over the adhesion obtained after the first lamination step here as well.
  • the method according to the invention can be carried out favorably in terms of energy efficiency. It is not necessary that the adhesion of the lamination to the associated layer is already completed in the respective lamination step.
  • a temporally preceding lamination step can initially instead be used only to adhere or bond the lamination associated with the layer to the latter.
  • a complete composite that meets practical requirements does not have to take place already in the temporally preceding lamination step.
  • the process energy introduced in the subsequent lamination step(s) is instead used to improve the adhesion between a layer and a lamination which were initially bonded in a temporally preceding lamination step.
  • the process energy is there not confined to heat input.
  • the pressing pressure applied for a subsequent lamination step in conjunction with a pressing time can instead be used synergistically in the same way.
  • substantially planar, multi-ply intermediate products are respectively produced in the first and second lamination steps.
  • the lamination is there typically carried out in a flatbed lamination system.
  • a substantially planar ply composite has been produced.
  • the first layer of the ply composite is typically visible on the face side of the trim element and can be formed by a veneer.
  • this ply composite is bonded at its rear side facing away from the face side to the second layer.
  • the first lamination provided between the first layer and the second layer is typically used to bond the first and the second layer to one another.
  • the result in a substantially planar intermediate product, referred to as a sandwich structure which is provided with the second lamination on its rear side.
  • this second lamination is bonded to the second layer.
  • a lamination in the sense of the present invention is thereby a single or multi-layer adhesion-promoting-sheet, which in the lamination step bonds at least on one side to the associated layer.
  • the first lamination bonds to one surface of the second layer
  • the second lamination bonds to the opposite surface of the second layer.
  • the surface of the adhesion-promoting-sheet associated with the first layer can either be changed or remain unchanged in the second lamination step due to adhesion.
  • the second lamination connected to the second layer in the second lamination step is usually exposed at the back of the second layer after the second lamination step.
  • the sandwich structure is prepared for the injection of a plastic material forming the reinforcement layer.
  • Pressures of between 0.5 and 2 N/mm 2 act in the first or second lamination step, respectively.
  • the sandwich structure thus produced is typically trimmed in an intermediate step, so that the outer contour substantially corresponds to the contour of the finished product. Certain regions of the first or second layer can protrude beyond the final contour of the trim element and be used for positioning or holding during the subsequent back injection molding.
  • the initially planar sandwich structure Prior to the back injection molding, the initially planar sandwich structure is deformed such that the contour of the sandwich corresponds to the three-dimensional contour of the trim element to be produced.
  • the rear side reinforcement layer is formed by fused arrangement of a plastic material against a rear side of the second layer and bonded to the second lamination, namely by way of injection molding.
  • the method is preferably carried out in such a way that the heat introduced in a second lamination step takes the first lamination to a temperature not less than the maximum temperature in the first lamination during the first lamination step.
  • the pressing time or the pressing pressure, respectively should also be applied in the same manner.
  • the pressing time should be longer than the pressing time applied in the temporally preceding lamination step.
  • the pressing time is the time in which the lamination is abutted under pressure against the associated layer.
  • the first pressing time is accordingly that time during which the first layer is abutted under pressure against the first lamination.
  • the process heat typically also acts at the phase boundary between the first lamination and the first layer.
  • the pressing pressure used during the first lamination step does not necessarily have to be less than the pressing pressure of the second lamination step. However, the pressing pressure should not drop in relation to the pressure applied in a temporally preceding lamination step.
  • the present invention can also be employed for multi-ply laminations, the individual plies of which are bonded to each other in a temporally subsequent manner and to different layers.
  • the ply of the lamination associated with a first layer can be regarded as being the first lamination within the meaning of the present invention, whereas the second ply abutted flat against this first lamination can be regarded as being a second lamination within the meaning of the present invention.
  • This second lamination is typically directly bonded to the second ply in the second lamination step.
  • the process energy used there also improves the adhesion between the first ply, i.e. the first lamination, and the first layer.
  • the advantages of the invention discussed below with regard to laminations on different surfaces of a single layer also apply to the specifics described above. Nevertheless, it is preferable in practice to prepare multi-ply laminations first separately to form the respective layers and to combine them with one of the layers as a multi-ply lamination.
  • the second layer is abutted against the first layer prior to the second lamination step with the interposition of the first lamination.
  • the second lamination is bonded to the second layer in the second lamination step.

Not only the second lamination is thus bonded in the second lamination step to the second layer.

  • the veneer can then be bonded more gently to the laminate in the back of the veneer than the layer provided under adhesive bonding of this lamination to the lamination associated therewith which is regularly disposed opposite to the veneer.
  • the veneer represents the first layer, whereas the layer bonded thereto under the medium of the first lamination constitutes the second layer within the meaning of the present invention.
  • the present invention can be guided by the idea that the maximum temperatures in the respective lamination are to be controlled. Due to thermally conductive processes, this maximum temperature can actually only be measured after the completion of a lamination step. The temporal performance of the lamination step and the measurement of the maximum temperature can therefore differ in time.

If the first layer determines at least predominantly the face side decorative surface of the trim element, the fused plastic material is abutted on the rear side against the second layer. This can be done by injection molding or foaming, commonly in an enclosed cavity. The pressure acting there and the temperature improve the adhesion of the plastic material to the second layer which on the rear side is provided with the second lamination, where the second lamination causes the adhesive bonding between the plastic material and the second layer.

  • This through-hole passes through the first layer and the lamination.
  • a cavity pressure acting during the formation of the reinforcement layer on the rear side of the second layers presses a region of the second layer, which is located on the rear side of the first layer, into the at least one through-hole.
