Abstract
Description
Die Erfindung betrifft ein Verbundmaterial mit einem flächigen, ein- oder mehrschichtigen Substrat aus thermoplastischem Kunststoff und mindestens einer von dem Substrat ablösbaren Oberflächenschutzfolie.The The invention relates to a composite material with a flat, single or multi-layer substrate made of thermoplastic material and at least one surface protective film removable from the substrate.
Oberflächenschutzfolien werden in vielen Bereichen eingesetzt, wo hochwertige und/oder empfindliche Oberflächen gegen mechanische Einwirkungen geschützt werden müssen. Die Oberflächenschutzfolien sollen einen temporären Oberflächenschutz gewährleisten, der die Oberfläche des Substrats bei der Verarbeitung oder beim Transport schützt. Danach kann die Oberflächenschutzfolie entfernt und entsorgt werden. Schutzfolien werden beispielsweise zum Schutz von glänzenden oder transparenten Kunststoffplatten oder als Kaschierfolien für den temporären Schutz von Küchen- und Möbeloberflächen oder Oberflächen von Hausgeräten verwendet. Ferner werden Oberflächenschutzfolien auf Platten aufgebracht, die durch Tiefziehen zu Formteilen weiter verarbeitet und/oder einer mechanischen Bearbeitung z. B. durch Bohren oder Schneiden, unterworfen werden. Die Oberflächenschutzfolien werden in einem Kaschierprozess auf das zu schützende Substrat aufgebracht. Beim Kaschieren werden übliche Kaschierklebstoffe verwendet oder es werden Oberflächenschutzfolien eingesetzt, die bereits eine durch Coextrusion hergestellte Haftschicht aus einem Permanentklebstoff aufweisen. Die Kleber- bzw. Haftschicht muss auf das Substrat, die Prozess- und/oder Lagerbedingungen abgestimmt werden, damit die Oberflächenschutzfolie später leicht und rückstandsfrei von dem Substrat wieder abgelöst werden kann.Surface protection films are used in many areas where high quality and / or sensitive surfaces must be protected against mechanical effects. The Surface protection films should be a temporary surface protection guarantee, the surface protects the substrate during processing or during transport. After that can remove the surface protection film and disposed of. Protective films are for example for protection of shining or transparent plastic sheets or as laminating films for temporary protection of kitchen and furniture surfaces or surfaces used by home appliances. Furthermore, surface protection films are on Plates applied, which further processed by deep drawing to form parts and / or a mechanical processing z. B. by drilling or Cutting, to be subjected. The surface protection foils are in a lamination process applied to the substrate to be protected. When laminating are common Laminating adhesives used or there are surface protection films which already used an adhesive layer produced by coextrusion made of a permanent adhesive. The adhesive or adhesive layer must be matched to the substrate, the process and / or storage conditions so that the surface protection film will be lightweight later and residue-free detached from the substrate again can be.
Aus WO 94/03337 ist eine mehrschichtige Lackfolie bekannt, die bei der Herstellung von Kunststoffspritzgussteilen in eine Form eingelegt und hinterspritzt wird. Auf die Lackfolie ist eine Oberflächenschutzfolie durch Kaschieren aufgebracht, die so dimensioniert ist, dass die Lackfolie beim Spritzgießen nicht be schädigt wird. Die Lackfolie bildet eine beispielsweise glänzende Dekoroberfläche auf dem spritzgeformten Kunststoffteil. Die an der Oberfläche des entformten Kunststoffteils haftende Schutzfolie kann als temporärer Oberflächenschutz noch während des Transports und der Handhabung der Teile genutzt werden.Out WO 94/03337 is a multilayer paint film known in the Production of plastic injection molded parts inserted into a mold and is back-injected. On the paint film is a surface protection film applied by laminating, which is dimensioned so that the Lackfolie during injection molding not damaged becomes. The paint film forms an example shiny decorative surface the injection molded plastic part. The on the surface of the Molded plastic part adhering protective film can be used as a temporary surface protection while still the transport and handling of the parts.
Das Aufbringen der Oberflächenschutzfolie auf ein Substrat erfordert im Rahmen der bekannten Maßnahmen einen aufwendigen Kaschiervorgang. Wird das Substrat mit aufkaschierter Schutzfolie einer nachträglichen Wärmebehandlung beispielsweise beim Tiefziehen oder einer Thermoumformung, ausgesetzt, hat dies häufig einen unerwünschten Einfluss auf die Haftung zwischen Schutzfolie und Substrat. Bei einer nachträglichen Erwärmung steigt die Haftkraft nämlich bisweilen stark an, was dann zu Problemen beim Abziehen der Oberflächenschutzfolie führen kann.The Apply the surface protection film on a substrate required in the context of the known measures an elaborate laminating process. Is the substrate with laminated Protective film of a subsequent heat treatment for example, during deep drawing or thermoforming, exposed, has this often an unwanted influence on the adhesion between the protective film and the substrate. In a subsequent warming namely, the adhesive strength increases sometimes strong, which then leads to problems when peeling off the surface protection film to lead can.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Verbundmaterial anzugeben, dessen Schutzfolie leicht und rückstandsfrei von dem Substrat abgelöst werden kann. Dabei soll sich insbesondere eine nachträgliche Erwärmung des Verbundmaterials bei der Weiterverarbeitung, z. B. beim Tiefziehen, nicht auf die Haftung zwischen Oberflächenschutzfolie und Substrat auswirken.In front In this background, the invention is based on the object Specify composite material whose protective film light and residue-free detached from the substrate can be. In particular, a subsequent heating of the composite material should in further processing, for. B. in deep drawing, not on the Adhesion between surface protection film and substrate impact.
Ausgehend von einem Verbundmaterial mit einem flächigen ein- oder mehrschichtigen Substrat aus thermoplastischem Kunststoff und mindestens einer von dem Substrat ablösbaren Oberflächenschutzfolie wird die Aufgabe erfindungsgemäß dadurch gelöst, dass das Substrat und die Oberflächenschutzfolie durch Coextrusion gemeinsam hergestellt sind und einen Coextrusionsverbund bilden, wobei die Haftung im Coextrusionsverbund an der Oberfläche des Substrats durch Wahl der Polymere in den zueinander benachbarten Schichten so eingestellt ist, dass die Oberflächenschutzfolie rückstandsfrei von der Ober fläche des Substrats abziehbar ist. Erfindungsgemäß wird die Oberflächenschutzfolie zusammen mit dem Substrat durch Coextrusion hergestellt. Bei dem Substrat kann es sich um ein- oder mehrschichtige Folien oder ein- oder mehrschichtige Platten handeln. Als Platten werden im Rahmen der Erfindung Kunststoffbahnen mit einer Dicke von mehr als 200 μm verstanden. Durch Wahl der Polymere bzw. Polymermischungen in den zueinander benachbarten Schichten ist es möglich, eine definierte Trennebene zwischen der Oberflächenschutzfolie und dem Substrat zu erzeugen, an der die Oberflächenschutzfolie und das Substrat getrennt werden können, wenn ein Oberflächenschutz nicht mehr benötigt wird.outgoing from a composite material with a one-layer or multi-layered sheet Thermoplastic substrate and at least one of removable from the substrate Surface protection film The object is achieved by the invention solved, that the substrate and the surface protection film coextruded together and a coextrusion composite form, wherein the adhesion in the coextrusion on the surface of the Substrate by choosing the polymers in the adjacent to each other Layers is adjusted so that the surface protection film remains residue-free the upper surface of the substrate is removable. According to the invention, the surface protection film produced together with the substrate by coextrusion. In which Substrate may be single or multilayer films or or multi-layered plates. As plates are in the frame the invention plastic sheets with a thickness of more than 200 microns understood. By choosing the polymers or polymer mixtures in each other neighboring layers it is possible a defined parting plane between the surface protection film and the substrate to produce at which the surface protection film and the substrate can be separated if a surface protection is no longer needed.
Erfindungsgemäß entfällt ein aufwendiger Kaschierprozess zur Verbindung der Oberflächenschutzfolie und des Substrats. Durch definierte Bedingungen bei der Coextrusion kann die Haftung zwischen der Oberflächenschutzfolie und dem Substrat genau und reproduzierbar eingestellt werden. Da das Zusammenführen des Substrats und der die Oberflächenschutzfolie bildenden Schicht bei hohen Temperaturen im Schmelzzustand erfolgt, hat eine nachträgliche Erwärmung bei der Weiterverarbeitung des Verbundmaterials keinen starken Haftanstieg mehr zur Folge. Folglich kann im Rahmen der erfindungsgemäßen Lehre sichergestellt werden, dass die Oberflächenschutzfolie auch nach einer Weiterverarbeitung des Verbundmaterials durch Thermoumformung bzw. Tiefziehen leicht und rückstandsfrei von dem Substrat ablösbar ist.According to the invention, there is no need for a complex laminating process for bonding the surface protection film and the substrate. By defined conditions in the coextrusion, the adhesion between the surface protection film and the substrate can be set accurately and reproducibly. Since the combination of the substrate and the surface protective film forming layer is carried out at high temperatures in the melt state, subsequent heating in the further processing of the composite material no longer leads to a strong adhesion increase. Consequently, it can be ensured in the context of the teaching according to the invention that the surface protection film also after a Weiterverar Processing of the composite material by thermoforming or thermoforming is easy and residue-free detachable from the substrate.

Insbesondere dann, wenn das Substrat eine größere Dicke aufweist, ist das Substrat zweckmäßig mehrschichtig ausgebildet und ist nur ein an die Oberfläche angren zender Bereich oder die Kernschicht durch Zusatz von Pigmenten eingefärbt. Ferner besteht die Möglichkeit, dass das Substrat eine Oberflächenschicht aufweist, die Nanopartikel enthält. Die Nanopartikel werden bei der Coextrusion des Materials zudosiert und verleihen der Oberfläche des Substrats gute mechanische Eigenschaften. Unter anderem wird die Oberfläche hierdurch kratzunempfindlich.The Substrate may be colored by the addition of pigments. In particular, then if the substrate has a greater thickness has, the substrate is suitably formed multi-layered and is only one to the surface Angren Zender area or the core layer colored by the addition of pigments. Further it is possible, that the substrate has a surface layer comprising nanoparticles. The nanoparticles are added during the coextrusion of the material and give the surface of the substrate has good mechanical properties. Among other things will the surface thus insensitive to scratching.
Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Lehre weist der Coextrusionsverbund eine mechanisch geglättete oder geprägte Oberfläche auf. Der Coextrusionsverbund kann direkt nach dem Extrudieren inline geprägt oder geglättet werden.
