Definitions

  • the invention relates to a method for producing interior trim parts.
  • interior parts for vehicles consist of a rigid molded carrier part, a spacer fabric arranged on its surface and a layer of real leather arranged thereon and which are connected to one another by adhesive layers. These interior fittings are to be produced in such a way that the back of a leather blank is glued to a spacer fabric or fleece and this composite is glued to the separately produced rigid surface of the molded carrier part.
  • a method for producing a foam molding which has an embossed leather dress is provided.
  • the process for producing such a foam molding takes place in such a way that the leather dress, which is composed of individually sewn leather parts, is first attached to a plastic film that covers the seams of the leather dress and then the leather dress with the plastic film on the the side facing the plastic film is foamed.
  • Document DE-A 199 26 470 describes a method for applying a barrier layer to the back of a decorative cover, in particular for an interior trim part, in which the barrier layer is intended to prevent the penetration of adhesive or plastic material and which is shaped in a negative mold.
  • the invention has for its object to provide a method for the production of interior trim parts, which avoids the disadvantages of the known solutions and which allows the manufacture of dimensionally stable bodies in the intermediate step, which are only back-foamed in a second step.
  • the object is achieved in that a decorative layer, a barrier layer, a thermoplastic adhesive layer and a textile layer are connected to one another and formed into an interior trim part and then back-injected or back-foamed with a thermoplastic polymer or a foam. Expanding polypropylenes or foam-forming polyurethanes are used as foams for the purposes of the invention.
  • the interior trim parts produced in this way have a soft grip on the decorative surface and, as a shaped interior trim part, can also be stored as an intermediate part in front of the back-foaming.
  • Aqueous dispersions of polyacrylates and / or acrylic acid copolymers containing amide groups are preferably used as a barrier layer in a thickness of 1 to 800 ⁇ m.
  • a reactive slide and / or an adhesive nonwoven with a melting point T m ⁇ 150 ° C. and / or a latent reactive slide with a crosslinking temperature ⁇ 100 ° C. is preferably used as the adhesive layer.
  • Adhesive layers of this type allow the decorative layer to be firmly connected to the nonwoven layer and to form an intermediate molded part. Crosslinking temperatures> 100 ° C can also be used if damage can be excluded by cooling the visible side of the decorative layer.
  • the decorative, adhesive and nonwoven layers are laminated together.
  • the laminated parts can be punched and sharpened at the edges to reduce the seam bead.
  • Advantages are produced from the laminate obtained in this way, which are sewn into a decorative dress and provided with seam seals.
  • the intermediate parts are produced in such a way that the decorative dress is applied to a positive shape, existing seams at room temperature aligned and shaped using heat and pressure, and fixed in the mold by cooling under pressure to room temperature.
  • a negative pressure is applied to the back of the decorative dress.
  • the shape size is dimensioned so that it corresponds to the final size of the interior trim part minus the material thickness of the decorative dress.
  • the laminate parts fixed in their shape are preferably back-injected or back-foamed in a separate step and reworked by punching, milling or cutting.
  • a textile knitted fabric, woven fabric, nonwoven fabric, film, synthetic leather, in particular a tanned natural leather, is preferably used as the decorative material.
  • FIG. 1 shows the cross section through a decorative layer structure according to the invention.
  • the decorative layer 1 shows a cross section through the decorative layer structure.
  • the decorative layer 1 is provided with a barrier layer 2, a thermoplastic adhesive layer 3 and a textile layer 4.
  • the material used is cowhide hide, 1, 2 - 1, 4 mm thick, an aqueous polyacrylate dispersion thickened with ammonia, a hot-melt adhesive nonwoven (M-Web) made of copolyamides with T m : 105 - 110 ° C, a basis weight of 30 g / m 2 and polyethylene terephthalate / spunbonded used with an air permeability> 5 I min d s "2, and a basis weight of 85 g / m 2. on the A 300 ⁇ m thick layer is applied to the back of a leather sample using a roller coater, and after a drying time of approx. 2 minutes, the nonwoven is laminated with the coated leather and the hot-melt adhesive fleece at 110 ° C.
  • M-Web hot-melt adhesive nonwoven
  • thermoplastic hot-melt adhesive fleece improves the formability.
  • This laminate is fixed by vacuum on a positive mold and shaped at 90 ° C / 2 min. After the mold has cooled, the laminate is removed from the mold as a dimensionally stable pattern and transferred to a corresponding negative mold in order to be back-injected with PU foam using conventional technology. After curing and demolding, the desired leather-covered interior trim part is obtained.
