Abstract

The invention relates to a process for producing a multilayer product, in particular a trim part for vehicles, with an outer skin as decorative layer, a flexible-elastic intermediate layer of a plastic foam and a thin-walled support layer. The central feature of the invention is that, on the inner side of the outer skin which is located in one mould half, a flexible-elastic intermediate layer is produced at least in regions and in that, in the same mould half, a support layer consisting of a sprayable and curable plastic is then applied to the outer skin or intermediate layer.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines mehrlagigen Erzeugnisses,insbesondere eines Ausstattungsteiles für Fahrzeuge, mit einer Außen aut als Dekorschicht, einer weichelastischen Zwischen­ schicht aus einem Kunststoffschaum und einer dünn­ wandigen Trägerschicht.The invention relates to a method for manufacturing a multilayer product, in particular one Equipment part for vehicles, with an external aut as a decorative layer, a soft elastic intermediate layer of a plastic foam and a thin walled carrier layer.

Verfahren zum Herstellen derartiger Schichtkörper sind bekannt. Sie bestehen z.B. aus einer folienartigen Dekorschicht, die in eine Tiefziehform eingelegt wird, ferner wird in diese Form eine aus einem ausreichend eigenstabilen Werkstoff bestehende Trägerschicht ein­ gelegt und sodann wird der Zwischenraum zwischen der Dekorschicht und der Trägerschicht mit einem Kunst­ stoffschaum ausgefüllt, wobei gleichzeitig sowohl die Dekorschicht als auch die Trägerschicht ausreichend fest an der aus Kunststoff bestehenden Zwischenschicht haften. Die mit diesem Herstellungsverfahren ver­ bundenen Maßnahmen, nämlich das getrennte Herstellen der Außenhaut oder Dekorschicht und der dünnwandigen Trägerschicht sowie das Einlegen dieser Schichten in die Schäumform sind aufwendig.Processes for producing such laminates are known. They exist e.g. from a foil-like Decorative layer, which is inserted into a deep-drawing mold, furthermore, in this form, one becomes sufficient intrinsically stable material existing carrier layer and then the space between the Decorative layer and the backing layer with an art  filled foam, while both the Decorative layer as well as the carrier layer are sufficient firmly on the plastic intermediate layer be liable. The ver with this manufacturing process related measures, namely the separate manufacturing the outer skin or decorative layer and the thin-walled Carrier layer and the insertion of these layers in the foam shape is complex.

Die Erfindung bezweckt, ein Verfahren zum Herstellen eines mehrlagigen Erzeugnisses bzw. Schichtkörpers anzugeben, welches mit weniger Einzelschritten aus­ kommt und somit im Ergebnis weniger aufwendig und kostengünstiger ist.The invention aims to produce a method a multi-layer product or laminate specify which one with fewer individual steps comes and therefore less expensive and is cheaper.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß auf der Innenseite der Außenhaut, die sich in einer Formhälfte befindet, zumindest bereichsweise eine weichelastische Zwischenschicht erzeugt wird und daß sodann eine aus einem spritzfähigen und aushärtenden Kunststoff bestehende Trägerschicht aufgebracht wird.To achieve this object, the invention provides that on the inside of the outer skin, which is in a Half of the mold is located, at least in some areas soft elastic intermediate layer is generated and that then one from a sprayable and hardening Plastic existing carrier layer is applied.

Die Formhälfte ist zweckmäßigerweise eine Unterform und dient als Träger für eine in ihr erzeugte oder in sie eingelegte Außenhaut. Unmittelbar auf der Innen­ seite der Außenhaut wird entweder ganzflächig oder bereichsweise die weichelastische Zwischenschicht erzeugt, wobei dies bei geöffneter oder geschlossener Schäumform geschehen kann. Bei geöffneter Schäumform wird die aus einem Kunststoffschaum bestehende Zwischenschicht als Sprühbild aufgetragen, was unter Verwendung eines computergesteuerten Roboters erfolgen kann. Alternativ kann aber auch die die Außenhaut tragende Formhälfte mit einer weiteren Formhälfte geschlossen werden, ehe die aus dem Kunststoffschaum bestehende Zwischenschicht erzeugt wird. Nach Her­ stellung der Zwischenschicht wird die das Erzeugnis tragende Formhälfte in jedem Fall geschlossen, damit über der als Dekorschicht dienenden Außenhaut und der aus Kunststoffschaum bestehenden Zwischenschicht Hohl­ räume vorhanden sind, in die der spritzfähige und aushärtende Kunststoff zur Bildung der Trägerschicht eingebracht wird. Zur Herstellung des mehrlagigen Erzeugnisses bzw. Schichtkörpers sind somit nur noch wenige und unkomplizierte Einzelmaßnahmen notwendig, bei deren Durchführung ferner kaum Bedienungs- oder Handhabungsfehler auftreten können. Bei verfahrens­ gemäßer Herstellung ist aus diesem Grund schließlich auch mit einem geringen Ausschuß zu rechnen.The mold half is expediently a lower mold and serves as a carrier for a generated in it or in she inserted outer skin. Immediately on the inside side of the outer skin is either over the entire surface or the soft elastic intermediate layer in some areas generated, this with open or closed Foaming can happen. When the foam mold is open is made of a plastic foam Intermediate layer applied as a spray pattern, what is below  Use a computer-controlled robot can. Alternatively, the outer skin can also be used load-bearing mold half with another mold half be closed before the plastic foam existing intermediate layer is generated. According to Her Position of the intermediate layer is the product supporting mold half closed in any case, so over the outer skin serving as a decorative layer and the intermediate layer made of plastic foam hollow rooms are available in which the injectable and hardening plastic to form the carrier layer is introduced. For the production of the multilayer Product or laminate are therefore only few and uncomplicated individual measures necessary, in their implementation also hardly any operating or Handling errors can occur. In process for this reason, proper manufacturing is ultimately also to count on a small committee.

Die Erfindung wird nachstehend anhand von Ausführungs­ beispielen, die in der Zeichnung schematisch dargestellt sind, näher beschrieben. Dabei zeigen:The invention is based on execution examples shown schematically in the drawing are described in more detail. Show:

Fig. 1 im Schnitt zwei geschlossene Formhälften mit einer in der Unterform befindlichen Außenhaut; FIG. 1 is closed in section, two mold halves with a lower mold disposed in the outer skin;

Fig. 2 im Schnitt zwei Formhälften vor der Her­ stellung der Trägerschicht; Fig. 2 on average two mold halves before the position of the carrier layer;

Fig. 3 im Schnitt das mehrlagige Erzeugnis und Fig. 3 in section the multilayer product and

Fig. 4 im Schnitt eine Formhälfte mit der in ihr befindlichen Außenhaut und einer aus Kunststoffschaum bestehenden Zwischen­ schicht, die ohne Schließen der Formhälfte erzeugt wird. Fig. 4 in section a mold half with the outer skin in it and an intermediate layer consisting of plastic foam, which is produced without closing the mold half.

Wie aus Fig. 3 hervorgeht, besteht ein mehrlagiges Erzeugnis 1 bzw. ein Schichtkörper 1 aus einer dünn­ wandigen , ausreichend eigenstabilen und räumlich beliebig geformten Trägerschicht 2, einer als Dekor­ schicht dienenden Außenhaut 3 und einer zumindest bereichsweise zwischen der Trägerschicht 2 und der Außenhaut 3 befindlichen, weichelastischen Zwischen­ schicht 4 aus einem Kunststoffschaum. Die Außenhaut 3 befindet sich gemäß den Fig. 1, 2 und 3 als unterste Lage in einer Formhälfte 5, in der sie entweder un­ mittelbar hergestellt worden ist (z.B. nach der Lehre des deutschen Patentes 34 17 727) oder in die sie nach entsprechender Herstellung eingelegt wird.As can be seen from FIG. 3, a multilayer product 1 or a laminate 1 consists of a thin-walled, sufficiently intrinsically stable and spatially arbitrarily shaped carrier layer 2 , an outer skin 3 serving as a decorative layer and one at least in regions between the carrier layer 2 and the outer skin 3 located, soft elastic intermediate layer 4 made of a plastic foam. The outer skin 3 is shown in FIGS. 1, 2 and 3 as the bottom layer in a mold half 5 , in which it has either been produced directly (for example, according to the teaching of German Patent 34 17 727) or in which it is produced accordingly is inserted.

Um zumindest bereichsweise auf der Außenhaut 3 eine weichelastische Zwischenschicht 4 aus einem Kunststoff­ schaum zu erzeugen, wird die Formhälfte 5 entweder gemäß Fig. 1 mit einer weiteren Formhälfte 6 geschlossen, so daß ein oder mehrere Hohlräume 7 verbleiben, in die der weichelastische Kunststoffschaum zur Bildung der Zwischenschicht 4 eingefüllt werden kann.In order to produce a soft-elastic intermediate layer 4 made of a plastic foam at least in regions on the outer skin 3 , the mold half 5 is either closed according to FIG. 1 with a further mold half 6 , so that one or more cavities 7 remain, into which the soft-elastic plastic foam forms the intermediate layer 4 can be filled.

Alternativ kann eine bereichsweise vorgesehene oder die gesamte Außenhaut 3 bedeckende Zwischenschicht 4 aber auch in der Weise erzeugt werden, daß sie unmittel­ bar bei geöffneter Formhälfte 5 gemäß Fig. 4 an den jeweils gewünschten Stellen der beim fertigen Erzeugnis innen liegenden Seite 8 der Außenhaut 3 aufgebracht wird. Dies kann z.B. mit einem Sprühkopf geschehen, den ein computergesteuerter Roboter trägt.Alternatively, a region-wise provided or the entire outer shell 3 covering the intermediate layer 4 but also be produced in such a manner that they 8 of the outer skin 3 is applied immediacy bar with open mold half 5 in Fig. 4 at the respective desired points of the inside of the finished product side becomes. This can be done, for example, with a spray head carried by a computer-controlled robot.

Nach Herstellung der weichelastischen Zwischenschicht 4 wird die Formhälfte 5 gemäß Fig. 2 mit einer Form­ hälfte 9 geschlossen, so daß über der weichelastischen Zwischenschicht 4 und/oder der Außenhaut 3 mindestens ein Hohlraum 10 zur Herstellung der Trägerschicht 2 bleibt. In den Hohlraum 10 wird in einem letzten Arbeitsgang ein spritzfähiger sowie aushärtender Kunst­ stoff zur Herstellung der eigenstabilen Trägerschicht 2 eingespritzt. Er verbindet sich mit dem die weich­ elastische Zwischenschicht 4 bildenden Kunststoffschaum bzw. auch gegebenenfalls bereichsweise mit der Außen­ haut 3, sofern die weichelastische Zwischenschicht 4 nicht an allen Stellen des mehrlagigen Erzeugnisses bzw. Schichtkörpers 1 vorgesehen ist.After production of the soft elastic intermediate layer 4 , the mold half 5 is closed according to FIG. 2 with a mold half 9 , so that at least one cavity 10 remains for producing the carrier layer 2 above the soft elastic intermediate layer 4 and / or the outer skin 3 . In the last step, an injectable and hardening plastic material is injected into the cavity 10 in order to produce the inherently stable carrier layer 2 . It connects to the plastic foam forming the soft elastic intermediate layer 4 or, if appropriate, in some areas to the outer skin 3 , provided that the soft elastic intermediate layer 4 is not provided at all points of the multilayer product or laminated body 1 .

Die Formhälfte 5, in der sich die Außenhaut 3 unmittel­ bar befindet, ist zweckmäßigerweise eine Unterform. Die Formhälfte 6 ist in diesem Fall eine Oberformhälfte einer Schäumform und dient nur zum Herstellen der weichelastischen Zwischenschicht 4, sofern diese Zwischenschicht 4 nicht bei geöffneter Formhälfte 5 gemäß Fig. 4 hergestellt wird.The mold half 5 , in which the outer skin 3 is immediately bar, is expediently a lower mold. In this case, the mold half 6 is an upper mold half of a foam mold and only serves to produce the soft-elastic intermediate layer 4 , provided that this intermediate layer 4 is not produced with the mold half 5 open according to FIG. 4.

Die Formhälfte 9 dient jeweils zum Schließen der Form­ hälfte 5, wenn die aus Kunststoff bestehende Träger­ schicht 2 hergestellt wird.The mold half 9 is used to close the mold half 5 when the plastic carrier layer 2 is made.
