Recyclingfähige Verbundtafeln bzw. -Folien aus thermoplastischem Kunststoff Recyclable composite panels or films made of thermoplastics
Stand der TechnikState of the art
Die Umweltbedingungen und die Gesetzgebung zur Abfallverwertung verlangen
heute recyclingfähige Produkte. Dies gilt vor allem für Massenprodukte wie
beispielsweise für die Kraftfahrzeugindustrie. Die Innenverkleidungen in Automobilen bestehen heute aus mehrlagigen Verbunden, deren Struktur aus
unter schiedlichen thermoplastischen Kunststoffen besteht. Ein Recycling (d.h. Einmahlen ohne Separieren der Schichten und Wiederverwendung
für den vornehmlich gleichen Einsatz-Zweck) ist wegen der Unverträglichkeit der unterschiedlichen Kunststoffe beim Re-Extrudieren
nicht möglich.
So besteht heute beispielsweise eine solche Tür-Innenverkleidung aus einerEnvironmental conditions and legislation on waste recycling now require recyclable products. This applies above all to mass products such as those used in the automotive industry. The interior panels in cars today consist of multi-layer composites whose structure consists of different thermoplastics. Recycling (ie grinding without separating the layers and reusing them for the same purpose) is not possible due to the incompatibility of the different plastics during re-extrusion.
For example, today such a door interior panel consists of a
- Schicht A (Trägerschicht) aus einer harten Polypropylen-Tafel, die mit Kreide oder Holzmehl gefüllt ist- Layer A (support layer) made of a hard polypropylene board filled with chalk or wood flour
Dicke ca. 2 - 3 mmThickness approx. 2 - 3 mm
- Schicht B (Polsterschicht) aus einer PVC-Schaumfolie. Dicke ca. 1,5 - 4 mm- Layer B (padding layer) made of PVC foam film. Thickness approx. 1.5 - 4 mm
- Schicht C (Dekorschicht) aus einer Folie mit einer Abmischung aus ABS - PVC.- Layer C (decorative layer) made of a film with a mixture of ABS - PVC.
Dicke ca. 0,4 - 1 mmThickness approx. 0.4 - 1 mm
Die Extrusion eines Mahlgutes aus obiger Struktur ist wegen des PVC-Anteiles in Verbindung mit den höheren Extrusionstemperaturen für PP nicht möglich, da hierbei das PVC thermisch abbaut.The extrusion of a ground material with the above structure is not possible due to the PVC content in conjunction with the higher extrusion temperatures for PP, as the PVC degrades thermally.

Problemproblem
Der Erfindung lag die Aufgabe zugrunde Verbundtafeln bzw. -folien zu entwickeln, die unter Beibehaltung der bisher bekannten mechanischen Eigenschaften ein Recycling unter Einsatz eines Co-Extrusionsverfahrens zulassen und damit die Wiederverwendung für das Ausgangsprodukt.The invention was based on the task of developing composite panels or films that, while retaining the previously known mechanical properties, allow recycling using a co-extrusion process and thus reuse for the starting product.
Erfindunginvention
Mit den Maßnahmen in den Ansprüchen 1 bis 4 wird das Problem gelöst. Der Aufbau erfüllt in der unterschiedlichen Konsistenz die bisher bekannten mechanischen Funktionen mit der nunmehr wichtigen Möglichkeit das sogenannte Regenerat in eine zusätzliche Schicht und damit für den Verbund wieder zu verwenden.The problem is solved with the measures in claims 1 to 4. The structure, in its different consistencies, fulfils the previously known mechanical functions with the now important possibility of reusing the so-called regenerate in an additional layer and thus for the composite.
Ein Ausführungsbeispiel einer Verbundtafel wird anhand der Figur 1 bis 2 erläutert.An embodiment of a composite panel is explained using Figures 1 to 2.
Es zeigt:It shows:
Figur 1 eine Verbundstruktur 1 mit folgendem Aufbau:Figure 1 shows a composite structure 1 with the following structure:
- Schicht A (Trägerschicht) eine harte Tafel - Dicke 2 -3 mm - aus PP mit Füllstoff (Holzmehl oder Kreide) oder PP-natur mit Glasvlies kaschiert.- Layer A (support layer) a hard board - thickness 2 -3 mm - made of PP with filler (wood flour or chalk) or natural PP laminated with glass fleece.
- Schicht B und D (Klebeschicht) aus thermoplastichem Kleber, die bei der Extrusion der Schichten A und E coextrudiert werden oder Folien aus Heißschmelzekleber sind, die beim Verbinden der Schichten A-C-E (z.B. beim Warmpressen) reagieren.- Layers B and D (adhesive layer) made of thermoplastic adhesive, which are co-extruded during the extrusion of layers A and E or are films made of hot melt adhesive that react when the layers A-C-E are joined (e.g. during hot pressing).
-3--3-
Schicht C (Polsterschicht) aus PP-Vlies-Flächengewicht ca. 400 bis 1000 gr/m2- oder aus vernetztem PP-Schaum - Dichte ca. 30 bis 100 gr/dm3 Layer C (cushioning layer) made of PP fleece - weight per unit area approx. 400 to 1000 gr/m 2 - or made of cross-linked PP foam - density approx. 30 to 100 gr/dm 3
Schicht E eine Folie aus elastomermodifiziertem PP. Dicke ca. 0,6 bis 1,2 mm.Layer E is a film made of elastomer-modified PP. Thickness approx. 0.6 to 1.2 mm.
Figur 2 eine Verbundstruktur 2 mit zusätzlicher Schicht F aus dem Regenerat (Mahlgut) der Verbundstruktur 1.Figure 2 shows a composite structure 2 with an additional layer F made from the regenerate (ground material) of the composite structure 1.
Die Schicht F kann auch in einem Arbeitsgang mit der Schicht A coextrudiert werden.Layer F can also be coextruded with layer A in one operation.
Um den Überschuß an Mahlgut zu reduzieren ist auch eine Trennung der Schichten A, C und E möglich und als jeweiliges Regenerat (Mahlgut) dem Extrusionsprozeß zuzuführen.In order to reduce the excess of ground material, it is also possible to separate layers A, C and E and feed them into the extrusion process as regenerated material (ground material).
