Abstract

The plate (10) has a core (11) of waste cpd. foil material and an outer cover (12) of unpolar plastic material. The waste cpd. material comes from soft packing, broken down to slivers, and in the plate the metal foil slivers are pressed together by plastic material. The plate has an outer coat of plastic waste material which is rolled or melted. Pref. the waste material compounded with a metal foil is a thin-layered plastic foil for the core material and consists of PE-LD and/or PE-HD and/or PP and/or PE and/or PA or another plastic. The cover layer comprises a thin 0.5-3mm unpolar plastic layer, e.g. PE-LD. USE/ADVANTAGE - As a plate for panelling, sepn. or support purposes upholds the necessary physical values and incorporates the lowest possible proportion of new material.

Description

Die Erfindung betrifft eine Platte für Verschalungs-, Abtrennungs- oder Stützzwecke, die aus Kunststoff- und Nichtkunststoffmaterial zusammengesetzt ist.The invention relates to a plate for shuttering, Separation or support purposes made of plastic and Non-plastic material is composed.

Es sind Schaltafeln bekannt, die aus Kunststoffmaterial bestehen und zu ihrer Verstärkung einen metallischen Ver­ steifungsrahmen, metallische Versteifungseinlagen oder Verstärkungsbeimischungen aus Glasfasern, Geweben o. dgl. aufweisen. Hierbei werden durchweg Neumaterialien verwen­ det.Formwork panels are known which are made of plastic material exist and to reinforce a metallic Ver stiffening frame, metallic stiffening inserts or Reinforcement admixtures made of glass fibers, fabrics or the like. exhibit. New materials are used throughout det.

Der Erfindung liegt die Aufgabe zugrunde, eine Platte der eingangs genannten Art unter Einhaltung der erforder­ lichen physikalischen Werte mit einem geringstmöglichen Anteil an Neumaterial zu fertigen.The invention has for its object a plate  of the type mentioned at the outset in compliance with the required physical values with the lowest possible Proportion of new material to be produced.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei dieser Platte mindestens ihr Kern aus Abfällen aus einem Verbundmaterial besteht, das sich überwiegend aus dünnschichtigem Metall- und Kunststoffmaterial zusammen­ setzt. Die Platte hat also den Vorteil, daß sie ganz oder überwiegend aus Abfallmaterial gefertigt ist, insbesondere aus einem Abfall-Verbundmaterial, das sich schlecht auf andere Weise entsorgen läßt. Es handelt sich um sog. Weichverpackungen mit einer beschichteten Metallfolie, die in großem Umfange zu Verpackungszwecken für flüssige Gegenstände im Einsatz sind und sich nur in begrenztem Umfange durch Mehrwegpackungen ersetzen lassen.The object is achieved according to the invention in that that with this plate at least its core from waste a composite material that consists mainly of thin-layer metal and plastic material together puts. The plate has the advantage that it is completely or is predominantly made from waste material, in particular from a waste composite material that is bad on dispose of another way. It is a so-called Soft packaging with a coated metal foil that on a large scale for packaging purposes for liquid Objects are in use and are limited Have it replaced with reusable packaging.

Vorteilhafterweise kann die Platte das Abfall-Verbund­ material zu Schnitzeln zerkleinert enthalten, wobei die Metallfolienschnitzel durch Kunststoffmaterial miteinander preßverbunden sind.The plate can advantageously be the waste composite material shredded into chips, the Scraps of metal foil through plastic material with each other are press-connected.

Es hat sich gezeigt, daß eine erfindungsgemäß ausgebildete Platte sich in ihren Eigenschaften auch an unterschied­ liche Einsatzzwecke anpassen läßt. So ist es möglich, die in ihrem Kern befindlichen Metallfolienschnitzel in eine Längsrichtung zu orientieren und in dieser Ausrichtung durch das Kunststoffmaterial in flächiger Berührung zu einem geschlossenen Mehrlagen-Metallfolien-Verbundkörper zu verkleben und zu verpressen. It has been shown that a trained according to the invention Plate also differed in their properties Liche uses can be adapted. So it is possible that in its core metal foil chips in a Orientate longitudinally and in this orientation through the plastic material in flat contact a closed multilayer metal foil composite body to glue and press.  

Die Platte kann zweckmäßig eine aufgewalzte oder aufge­ schmolzene Außenhaut aufweisen, die ebenfalls aus Kunst­ stoff-Abfallmaterial bestehen kann. Es kann sich um sehr dünne Deckschichten aus einem unpolaren Kunststoffmaterial handeln, beispielsweise aus PE-LD.The plate can expediently be rolled or opened have melted outer skin, which is also made of art waste material can exist. It can be very thin cover layers made of a non-polar plastic material act, for example from PE-LD.

Die erfindungsgemäß ausgebildete Platte kann auf unter­ schiedliche Weise hergestellt werden, beispielsweise durch Kalandern oder aber durch Formpressen aus dem Verbundmate­ rial. Sie kann aber auch durch Extrusion aus dem Verbund­ material gefertigt sein. Die Platte läßt sich auch mit ge­ ringer Stärke herstellen, wobei ihr Verbundmaterialkern eine Stärke von nur wenigen mm aufweisen kann. Ein vor­ teilhaftes Verfahren zur Herstellung einer erfindungsgemäß ausgebildeten Platte ist dadurch gekennzeichnet, daß das Kernmaterial aus Metall-/Kunststoff-Verbundfolienschnit­ zeln auf einem Doppelschnecken-Extruder mit geringer Friktion aufgearbeitet und anschließend durch eine Breitschlitzdüse geführt und in einem nachgeschalteten Glätt- und Preßwalzenwerk verdichtet wird, bevor Kunst­ stoffdeckschichten thermisch aufgewalzt oder aufgeschmol­ zen werden und durch gekühlte Preßwalzen eine Endverdich­ tung der Platte erfolgt.The plate designed according to the invention can be found under be produced in different ways, for example by Calendering or by compression molding from the composite material rial. But it can also by extrusion from the composite be made of material. The plate can also be used with ge Produce wrestling starch with its composite material core can have a thickness of only a few mm. A before Partial process for producing an inventive trained plate is characterized in that the Core material made of metal / plastic composite film cut on a twin-screw extruder with low Worked up friction and then by a Wide slot nozzle guided and in a downstream Smoothing and press roll mill is compacted before art cover layers thermally rolled or melted zen and a final compression by cooled press rolls tion of the plate takes place.

Die beiliegende Zeichnung zeigt schematisch einen Teil einer erfindungsgemäß ausgebildeten Platte 10 mit einem Kern 11 aus Abfall-Verbundfolienmaterial und einem Außen­ mantel 12 aus unpolarem Kunststoffmaterial. Der Kern 11 besteht aus Schnitzeln einer Metall-/Kunststoff-Verbund­ folie, bei welcher die Metallfolie aus Aluminium oder Kupfer und die Kunststoffolie aus PE-LD oder PE-HD oder aus PP, PET, PA besteht. Durch den thermoplastischen Kunststoffanteil an den Verbundfolien erübrigt sich in der Regel der Aufwand von zusätzlichem Kunststoffmaterial zum gegenseitigen Verbinden der Metallschnitzel des Kernes 11.The accompanying drawing shows schematically a part of a plate 10 designed according to the invention with a core 11 made of waste composite film material and an outer jacket 12 made of non-polar plastic material. The core 11 consists of chips of a metal / plastic composite film in which the metal film is made of aluminum or copper and the plastic film is made of PE-LD or PE-HD or of PP, PET, PA. The thermoplastic part of the composite films generally eliminates the need for additional plastic material to interconnect the metal chips of the core 11 .

Eine Platte der genannten Zusammensetzung ist nagelbar und erlaubt das Verankern von Schrauben, so daß sie in dieser Hinsicht der Qualität handelsüblicher Spanplatten ent­ spricht. Sie ist wasserfest. Ihr Metallanteil ergibt eine gute Wärmeverteilung und dadurch auch eine grobe Festig­ keit gegen ein Verziehen beim Einsatz der Platten im Freien. Bei der Verwendung der Platten als Schalbretter erübrigt sich ihre Beschichtung mit einem Trennmittel. Um­ mantelte Platten lassen sich leicht mit einer Oberflächen­ prägung versehen.A plate of the composition mentioned is nailable and allows anchoring screws so that they are in this Regarding the quality of commercial chipboard ent speaks. It is waterproof. Your metal content is one good heat distribution and therefore a coarse strength against warping when using the panels in the Outdoors. When using the panels as formwork boards there is no need to coat them with a release agent. Um covered panels can be easily with a surface embossed.
