Description
Die Erfindung betrifft ein Verfahren zum Trennen von Verbundkörpern, die zumindest eine innere Schicht oder einen Kern aus Schaumstoff und eine die Schaumstoffschicht bzw. den Schaumstoffkern zumindest teilweise bedeckende Außenschicht oder Außenhülle aus textilem Material, Kunststoff, Kunstleder oder Leder aufweisen.The The invention relates to a method for separating composites which at least one inner layer or core of foam and one the foam layer or the foam core at least partially covering outer layer or Outer shell off textile material, plastic, artificial leather or leather.
Verbundkörper der eingangs genannten Art werden in großem Umfang z. B. in der Kraftfahrzeugindustrie, der Möbelindustrie oder auch der Gebrauchsgüterindustrie eingesetzt. In der Kraftfahrzeugindustrie werden u.a. Sitz- und Rückenelemente, Kopfstützen aber auch Abdeckungen, Verkleidungen, Mittelkonsolen oder Armaturentafeln als Verbundkörper hergestellt. Bei der Wiederverwertung derartiger Verbundkörper ergibt sich allerdings die Problematik, daß die einzelnen Schichten so fest miteinander verbunden sind, daß eine einfache Trennung nicht ohne weiteres möglich ist. Ein Wiederverwertung solcher Verbundkörper erfolgt zur Zeit durch Zerreißen und Verflocken der gesamten Teile, wobei die Flocken aus Schaum, Kaschierschaum und Stoffpartikeln bestehen. Wenn dann unter die Bezüge auch noch Sitzheizungen aus Edelstahldraht oder Sitzbelegungserkennungsmatten im Mix von Kupferdraht und Polykarbon-Kunststoff eingelegt sind, sind die Flocken u.U. auch mit diesen Materialien kontaminiert. Der so gewonnene Flockenmix wird gegenwärtig unter Zugabe von Klebstoffen mit Druck zu Blöcken verpreßt und zu Teilen wie Akustik- und Absorptionsteilen verarbeitet. Nach Ende dieses Teilelebens ist aufgrund der hohen Kontamination eine Trennung nur noch thermisch möglich.Composite of the The aforementioned type are used to a large extent z. In the automotive industry, the furniture industry or the commodity industry used. In the automotive industry, i.a. Seating and Back elements headrests but also covers, panels, center consoles or dashboards as a composite body produced. In the recycling of such composite results However, the problem that the individual layers so are firmly connected to each other, that a simple separation is not readily possible is. Recycling of such composite is currently done by rupture and Flocculate the entire parts, with the flakes of foam, laminating foam and particles of matter. If then under the covers too nor seat heaters made of stainless steel wire or seat occupancy recognition mats are inserted in the mix of copper wire and polycarbonate plastic, are the flakes u.U. also contaminated with these materials. The flake mix thus obtained is present with the addition of adhesives with pressure to blocks pressed and processed into parts such as acoustic and absorption parts. To The end of this part life is a separation due to the high level of contamination only thermally possible.
Auch bei der konventionellen Bezugstechnologie werden die Bezugstoffe zum leichteren Beziehen der in der Regel aus Polyurethan bestehenden Polsterträger vielfach mit einer Schnittschaumschicht und einer auf deren Rückseite aufgetragenen Gewebeschicht flammkaschiert. Auch hier ergibt sich das Problem einer sortenfreien Trennung von Stoff und Schaum.Also in conventional reference technology, the upholstery fabrics become for ease of obtaining the usually made of polyurethane padding support many times with a cut foam layer and one on the back applied fabric layer flame-laminated. Again, this results the problem of a sort-free separation of fabric and foam.

Aufgabe der Erfindung ist es, ein Verfahren zum schaffen, das ein einfaches und möglichst sortenreines Trennen von Schaumstoff und Bezug bzw. Außenschicht bei hinterschäumten Teilen und kaschierten Stoffen ermöglicht.task The object of the invention is to provide a method which is simple and as possible sorted separation of foam and cover or outer layer with foamy Parts and laminated fabrics allows.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.These The object is achieved by a method having the features of the claim 1 solved. Advantageous embodiments and advantageous developments of the invention are the subject of Dependent claims.
Bei dem erfindungsgemäßen Verfahren wird in den Übergangsbereich zwischen der inneren Schicht oder dem Kern und der Außenschicht bzw. der Außenhülle zunächst eine Flüssigkeit, vorzugsweise Wasser eingebracht. Anschließend wird der gesamte Verbundkörper einer Mikrowellen- oder Ultraschallwellenbehandlung unterzogen. Durch die Wellenbehandlung wird die eingebrachte Flüssigkeit in so große Schwingung versetzt, dass die Verbindung zwischen der Außenschicht bzw. der Außenhülle und der inneren Schaumstoffschicht oder dem Schaumstoffkern auf einfache Weise gelöst werden kann. Ein derartiger Effekt ist mit einer so hohen Effizienz durch normale Wärmebehandlung oder mittels Dampf nicht erreichbar.at the method according to the invention will be in the transition area between the inner layer or the core and the outer layer or the outer shell first one Liquid, preferably introduced water. Subsequently, the entire composite body of a Subjected to microwave or ultrasonic wave treatment. By The wave treatment, the introduced liquid is in such great vibration offset the connection between the outer layer or the outer shell and the inner foam layer or the foam core to simple Way solved can be. Such an effect is with such high efficiency through normal heat treatment or not accessible by steam.
Besonders gut ist dieses Verfahren zum Ablösen von Bezugsstoffen von hinterschäumten Teilen oder kaschierten Stoffen geeignet. Das Verfahren ist z. B. für eine mit Stoff, Leder oder Kunstleder bezogene Kopfstütze oder ein Polsterteil eines Kraftfahrzeugs verwendbar.Especially good is this method of detachment of cover fabrics of foam-backed Parts or laminated materials suitable. The method is z. B. for one upholstered with fabric, leather or imitation leather headrest or a upholstered part of a Motor vehicle usable.
Wenn es sich bei Außenschicht oder Außenhülle um einen textilen Stoff oder ein Gewebe handelt, kann die Flüssigkeit zweckmäßigerweise dadurch eingebracht werden, dass der Verbundkörper mit der Flüssigkeit besprüht wird, die dann bis zum Übergangsbereich eindringen kann. Der Verbundkörper kann aber auch in die Flüssigkeit eingetaucht werden. Bei Leder, Kunstleder oder Kunststoff kann die Flüssigkeit durch Nadelpunktion eingebracht oder injiziert werden. Die Flüssigkeit kann von der Vorder- oder Rückseite der Außenschicht oder Außenhülle eingebracht werden. Als Flüssigkeit kann zweckmäßigerweise Wasser verwendet werden, dem zusätzliche Mineralien zugesetzt werden können.If the outer layer or outer shell is a textile fabric or a fabric, the liquid may conveniently be introduced by spraying the composite with the liquid, which may then penetrate to the transition region. The composite can also be immersed in the liquid. For leather, artificial leather or plastic, the liquid can be introduced or injected by needle puncture. The liquid can be removed from the front or back of the outer layer or outer shell are introduced. As the liquid, water may be suitably used, to which additional minerals may be added.
Im Fall von hinterschäumten Lederbezügen kann das Wasser oder eine andere geeignete Flüssigkeit mit Hilfe feinster Nadelpunktion in den Übergangsbereich von Schaum und Leder gebracht werden. Dies kann sowohl von der Vorderseite (Durchstoßen des Leders) als auch von der Rückseite (Durchstoßen des Schaums) erfolgen.in the Case of foamy Leather covers can the water or other suitable liquid with the help finest Needle puncture in the transition area be brought by foam and leather. This can be done both from the front (Piercing of the leather) as well as from the back (puncture of the Foam).
Bei Versuchen hat sich gezeigt, dass durch Zugabe von Mineralien zu der Flüssigkeit, hier hat sich Chromsalz besonders bewährt, der Ablöseeffekt verstärkt wird und die Behandlungszeit verkürzt werden kann.at Experiments have shown that by adding minerals to the liquid, Here, chromium salt has proven particularly effective, the separation effect is enhanced and the treatment time is shortened can be.
Neben der vorstehend beschrieben Behandlung der Verbundkörper mit Mikrowellen können die für die Trennung eingesetzten Schwingungen auch durch einen Ultraschallschallerzeuger, wie z. B. eine Ultraschallsonotrode, erzeugt werden.Next the above-described treatment of the composite body with Microwaves can the for the separation of vibrations also by an ultrasonic generator, such as As an ultrasonic sonotrode be generated.
Die Erfindung ist nicht auf die vorstehend beschriebene Trennung von Schaum und Stoff bzw. Leder bei hinterschäumten Teilen und kaschierten Stoffen beschränkt. Sie ist überall dort einsetzbar, wo eine möglichst sortenfreie Trennung von Verbundkörpern mit einem Kern oder einer inneren Schicht aus Schaumstoff und einer Außenschicht oder einer Außenhülle aus textilem Material, Leder, Kunstleder oder Kunststoff erreicht werden soll.The Invention is not limited to the separation of Foam and fabric or leather with foam-backed parts and laminated Limited substances. She is everywhere can be used wherever possible sort-free separation of composites with a core or a inner layer of foam and an outer layer or outer shell textile material, leather, synthetic leather or plastic can be achieved should.

Im folgenden wird das Verfahren am Beispiel eines mit textilem Bezugsstoff bezogenen und im Hinterschäumverfahren hergestellten Bauteils, wie z. B. eine Kopfstütze oder ein Polsterteil eines Kraftfahrzeugs, beschrieben. Für die Trennung von Stoffbezug und Schaumstoffkern wird das Bauteil zunächst an der Außenseite mit einem feinen Wassernebel (ca. 3 bar) besprüht. Das Wasser wird von dem Stoffbezug aufgenommen und sinkt bis zum Übergangsbereich zwischen dem Bezugsstoff und dem Kaschierschaum ein. Nach einer vorgegebenen Einwirkzeit wird das gesamte hinterschäumte Bauteil einer Mikrowellenbestrahlung von ca. 200 bis 1000 Watt ausgesetzt. Nach dieser Behandlung kann der Stoffbezug nahezu schaumpartikelfrei vom Polsterträger abgenommen werden.in the The following is the method using the example of a textile fabric related and in the back foaming process manufactured component, such. B. a headrest or a cushion part of a Motor vehicle, described. For the separation of fabric cover and foam core becomes the component first on the outside sprayed with a fine water mist (about 3 bar). The water gets from the fabric cover recorded and sinks to the transition area between the cover fabric and the laminating foam. After a predetermined contact time is the entire backfoamed component exposed to a microwave irradiation of about 200 to 1000 watts. After this treatment, the fabric cover can be almost free of foam particles from the upholstery carrier be removed.
