Die Erfindung betrifft ein Verfahren zum Hochfrequenzverschweißen eines Polstermaterials, insbesonde- V) re für Armaturenbretter und Seiteninnenteiie an Kraftfahrzeugen, aus einer schlecht schweißbaren Schaumstoffbahn mit einer artfremden Unterlage aus beispielsweise Pappe, Karton od. dgl. durch Anordnen einer flexiblen thermoplastischen Bahn aus Kunststoff " mit einer Dielektrizitätskonstanten von 2,5 bis 6 und einem dielektrischen Verlustfaktor größer als 1,5 χ ΙΟ-3 zwischen Schaumstoffbahn und Unterlage.The invention relates to a method for high-frequency welding of upholstery material, insbesonde- V) re for dashboards and Seiteninnenteiie on motor vehicles, made of a poorly weldable foam sheet with an alien base made of, for example, cardboard or the like. By arranging a flexible thermoplastic sheet made of plastic "with a dielectric constant of 2.5 to 6 and a dielectric loss factor greater than 1.5 χ ΙΟ -3 between the foam sheet and the base.

Es ist bereits bekannt, nicht oder bedingt hochfrequenzschweißbare Materialien, wie Textilien, durch b0 Aufsintern eines pulverförmigen hochl'requenzschweißbaren Thermoplasten, wie Polyamid, hochfrequenzschweißbar zu machen, um insbesondere Nahtverbindungen herstellen zu können. Weiterhin ist es bekannt, bei im Hochfrequenzschweißverfahren schlecht M schweißbaren Kunststoffen, wie Polyurethanschaum oder Polystyrolschaum, mit artfremden Stoffen, z. B. Hartpappe, Karton, Papier od. dgl. eine schweißbare Folie aus PVC oder Lösungen von hochfrequenzschweißbaren Kunststoffen als Schweißmittel zwischen Schaumstoff und artfremdem Stoff einzubringen.It is already known, or not due hochfrequenzschweißbare materials such as textiles, by b0 sintering a powdery hochl'requenzschweißbaren thermoplastics such as polyamide, to make hochfrequenzschweißbar to be able to produce particular seams. Furthermore, it is known that in the high-frequency welding process poorly M weldable plastics, such as polyurethane foam or polystyrene foam, with alien substances, eg. B. hard cardboard, cardboard, paper od. The like. A weldable film made of PVC or solutions of high-frequency weldable plastics as welding means between foam and foreign material.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Herstellung von Polstermaterial auf der Basis von hochwertigen Schaumstoffen aus Polyäthylen durch H F-Verschweißung, die sich ebenfalls nicht H F-verschweißen lassen, zu schaffen. Es bestand ein Bedürfnis nach einem solchen Material, mit besonders wünschenswerten physikalischen Eigenschaften.The invention is based on the object of a simple production of cushioning material on the basis of high-quality foams made of polyethylene by H F welding, which are also not H F welded let create. There was a need for such a material, with particularly desirable ones physical properties.

Die Erfindung schließt diese Lücke dadurch, daß sie vorschlägt, Schaumstoffbahnen aus teilvernetztem Polyäthylen an Unterlagen in der Weise mustermäßig HF-anzuschweißen, daß man über und unter der Schaumstoffbahn hochfrequenzverschweißbare thermoplastische Kunststoffbahnen anordnet.The invention closes this gap in that it proposes foam sheets made of partially crosslinked polyethylene to be HF-welded to the documents in such a way that one is above and below the Foam sheet arranges high frequency weldable thermoplastic plastic sheets.

Durch die beidseitige Anordnung der Schweißhilfsmittel ist es möglich, ein hochwertiges Verbundbauteil auf Basis von teilvernetztem Polyäthylenschaumstoff herzustellen. Die flexiblen thermoplastischen Kunststoffbahnen bestehen aus Folien oder an der Außenseite auch aus entsprechenden Geweben oder Gewirken, die lose ein- bzw. aufgelegt werden oder die auf die Schaumstoffbahnen, bzw. die Unterlagen kaschiert sind. Die Unterlagen selbst bestehen z. B. aus Hartfaserplatten, Hartpapier, Pappe, Blech, Sperrholz, Hart-PVC, einem Äthylencopolymerisat od. dgl. Sie können mithin entweder starr oder auch biegsam sein.By arranging the welding aids on both sides, it is possible to produce a high-quality composite component on the basis of partially cross-linked polyethylene foam. The flexible thermoplastic plastic sheets consist of foils or on the outside of corresponding woven or knitted fabrics that are loosely inserted or laid on or which are laminated to the foam sheets or the documents. The documents themselves consist e.g. B. made of hardboard, hard paper, cardboard, sheet metal, plywood, hard PVC, an ethylene copolymer or the like. They can therefore either be rigid or flexible.

Geeignete Rohstoffe für die flexiblen Kunststoffbahnen sind z. B. Äthylcellulose, Acetylcellulose, Polyvinylchlorid, Mischpolymerisate aus Vinylidenchlorid und Vinylchlorid, Polymethacrylat, ABS-Polymereri oder vorzugsweise aus Polyamiden, z. B. auf der Basis von Terephtalsäure, Adipinsäure oder Caprolactam, oder Äthylencopolymerisaten z. B. Äthylen-Vinylacetat-Copolymere mit einem Acetatanteil von 8 bis 60%.Suitable raw materials for the flexible plastic sheets are, for. B. ethyl cellulose, acetyl cellulose, polyvinyl chloride, Copolymers of vinylidene chloride and vinyl chloride, polymethacrylate, ABS polymer or preferably made of polyamides, e.g. B. based on terephthalic acid, adipic acid or caprolactam, or Ethylene copolymers z. B. ethylene-vinyl acetate copolymers with an acetate content of 8 to 60%.

Bestehen die Unterlagen selbst aus einem H F-verschweißbarem Material, so können sie die Funktion besonderer Zwischenlagen mit übernehmen. Die Unterlagen können ein- oder beidseitig beschichtet v/erden und die Musterung erfolgt in Form von Streifen, Rechtecken, Punkten od. dgl., ggf. unter Bildung von Luftpolstern.If the documents themselves consist of an HF-weldable Material, so they can take over the function of special intermediate layers. The documents can be coated on one or both sides and the pattern is in the form of stripes, Rectangles, points or the like, possibly with the formation of air cushions.

Auf der über der Schaumstoffbahn liegenden thermoplastischen Kunststoffbahn kann eine Dekorfolie angebracht werden oder die betreffende Bahn ist selbst als Dekorfolie ausgebildet.A decorative film can be placed on the thermoplastic plastic web lying over the foam web be attached or the web in question is itself designed as a decorative film.

Zweckmäßig werden Schaumstoffbahnen aus gegebenenfalls teilvernetztem Polyäthylen mit einem Raum-Gewicht von 30 bis 200 kg/m3 bei einer Dicke von 2 bis 15 mm verwendet. Die Dicke der Folien liegt zwischen 0,1 und 2 mm. Bei Geweben und Gewirken handelt es sich um ein Material mit einer Fadenstärke, wie sie allgemein in der Textilindustrie üblich ist bei möglichst engem Kontakt der einzelnen Fäden. Es versteht sich von selbst, daß je dicker die dielektrisch erwärmbaren Materialien sind, um so besser durchführbar und haltbarer sind die erzielten Verbindungen.It is expedient to use foam webs made of optionally partially crosslinked polyethylene with a volume weight of 30 to 200 kg / m 3 and a thickness of 2 to 15 mm. The thickness of the foils is between 0.1 and 2 mm. In the case of woven and knitted fabrics, it is a matter of a material with a thread thickness that is common in the textile industry, with the individual threads in as close contact as possible. It goes without saying that the thicker the dielectrically heatable materials, the better the feasible and more durable the connections achieved.

Beispiel 1example 1

Der Materialaufbau besteht aus einer Hartfaserplatte, einer Copolymerisatfolie aus 87% Äthylen und 13% Vinylacetat, einem vernetzten Polyäthylenschaums'.off und einem Polyamidgewirke auf der Basis Terephthalsäure (Handelsname Trogamid T).The material structure consists of a hardboard, a copolymer film made of 87% ethylene and 13% Vinyl acetate, a cross-linked Polyäthylenschaums'.off and a polyamide knitted fabric based on terephthalic acid (Trade name Trogamid T).

Das Polyamid ist auf den Schaumstoff kaschiert. Die Copolymerisatfolie ist entweder lose eingelegt oder mit dem Schaumstoff oder der Hartfaserplatte fest verbun-The polyamide is laminated to the foam. The copolymer film is either inserted loosely or with firmly attached to the foam or hardboard

den. Wirkt auf diesen Aufbau ein HF-Feld, so werden die Polyamidfolie und die Copolymerisatfolie erwärmt Die Wärme überträgt sich auf den Schaumstoff, dessen Zellgefüge örtlich gewollt zusammenbricht ™nd der sich gleichzeitig mit der Copolymerisa'foüe verbindet und/oder diese Folie zusätzlich mit der Hartfaserplatte. Es entsteht ein Produkt mit dekorativer Oberfläche. Es ist also zweckmäßig, aber nicht erforderlich, daß ein Teil der Materialien bereits vor dem H F-Schweißvorgang miteinander z, B. durch kaschieren verbunden ist Ein ι ο Polyamidmaterial und besonders ein Copolymerisat des Äthylens werden bevorzugt verwendet, da sie sich ohne Haftvermittler auf den Schaumstoff kaschieren lassen.the. If an HF field acts on this structure, the polyamide film and the copolymer film are heated. The heat is transferred to the foam, the cell structure of which collapses on purpose and which at the same time bonds with the copolymerization and / or this film also with the hardboard . The result is a product with a decorative surface. It is therefore useful, but not necessary, that some of the materials are already connected to one another, e.g. by lamination, before the HF welding process. A ι ο polyamide material and especially a copolymer of ethylene are preferably used because they do not have an adhesion promoter let the foam hide.

Beispiel 2 |5 Example 2 | 5

Der Aufbau besteht aus einer Hartfaserplatte, einem Polyäthylenschaumstoff, einer Copolymerisatfolie, wie im Beispiel 1, und einer DekorfoKe aus Weich-PVC oder einem entsprechenden Kunstleder.The structure consists of a hardboard, a polyethylene foam, a copolymer film, such as in example 1, and a DekorfoKe made of soft PVC or a corresponding synthetic leather.

Beispiel 3Example 3

Der Aufbau besteht bei beidseitiger Beschichtung eines Trägermaterials aus einer Copolymerisatfolie gemäß Beispiel 1, außen oben und unten aus einem PVC-DekormateriaL Hierbei übernimmt das Trägermaterial gleichzeitig die Funktion einer besonderen Zwischenlage.When a carrier material is coated on both sides, the structure consists of a copolymer film according to example 1, outside above and below made of a PVC decorative material. Here, the carrier material simultaneously takes on a special function Liner.
