B. wood, applied, in particular to be glued. The product is said to B. can also be used as wallpaper or as a covering for products of all kinds. The product should be easy to stick to the substrate. If the article to which the product according to the invention is to be applied has sharp edges, it should be possible to bend it by coating with the film according to the invention. The film according to the invention is intended for a human user feel comfortable (so-called "softtouch"). It should have a high level of mechanical stability, in particular high splitting strength, and be easy to process further. In particular, the film according to the invention is intended to serve as a replacement for a conventional PVC film. Furthermore, the film product according to the invention should be as little as possible harmful to the environment during production, processing and possibly disposal.
Das erfindungsgemäße Verfahren zum Herstellen eines solchen folienartigen Erzeugnisses sieht folgende Schritte vor:The method according to the invention for producing such a film-like product provides the following steps:
- Auf einen porösen Träger wird ein Kunststoff, insbesondere Polyolefin aufgebracht, und- A plastic, in particular polyolefin, is applied to a porous carrier, and
durch Wärmeeinwirkung dringt der Kunststoff bzw. das Polyolefin homogen in den porösen Träger.the plastic or polyolefin penetrates homogeneously into the porous carrier due to the action of heat.
Das vorstehend beschriebene Verfahren führt zu einem erfindungsgemäßen FolienerZeugnis der einfachsten Art. Es hat eine hohe Spaltfestigkeit und fühlt sich für einen menschlichen Benutzer angenehm an; die Folie hat eine weiche, fast textilarti- ge Oberfläche.The method described above leads to the simplest type of film production according to the invention. It has a high splitting resistance and feels pleasant to a human user; the film has a soft, almost textile-like surface.
Als Polyolefin sind insbesondere verwendbar Polystyrol, Polypropylen und Polyethylen. Deratige Polyolefine werden nach dem Härten leicht milchig. Gemäß einer bevorzugten Ausgestaltung der Erfindung ist deshalb vorgesehen, daß auf den porösen Träger vor Aufbringung des Polyolefins eine sublimierbare Dispersionsfarbe aufgebracht wird. Wenn anschließend das Polyolefin auf den so mit Farbe bedruckten Träger aufgebracht wird, dringt das Polyolefin unter Wärmeeinwirkung in den porösen Träger und gleichzeitig oder später diffundiert die Farbe durch Wärmeeinwirkung im Polyolefin. Es entsteht insgesamt eine Folie, bei der der poröse Träger als "Gerüst" dient, in welches der Kunststoff, z. B. Polyolefin, homogen eingedrungen ist, also die porösen Lücken auffüllt. Eine solche Folie läßt sich in einfacher Weise auf ein Substrat, z. B. Holz, aufkleben, da der poröse Träger (im Unterschied zu Polyolefinen) leicht verklebbar ist. Als poröser Träger kommt insbesondere in Betracht ein Papier, insbesondere ein 80 g Papier.Polystyrene, polypropylene and polyethylene can be used in particular as the polyolefin. Such polyolefins become slightly milky after curing. According to a preferred embodiment of the invention, it is therefore provided that a sublimable emulsion paint is applied to the porous support before the polyolefin is applied. If the polyolefin is then applied to the support printed with ink, the polyolefin penetrates the porous support under the action of heat and, at the same time or later, the color diffuses through the action of heat in the polyolefin. The result is a film in which the porous support serves as a "framework" in which the plastic, for. B. polyolefin, has penetrated homogeneously, thus filling the porous gaps. Such a film can be easily placed on a substrate, e.g. B. wood, stick on, as the porous Carrier (unlike polyolefins) is easy to glue. A paper, in particular 80 g of paper, is particularly suitable as the porous carrier.
Nach Herstellen des Erzeugnisses in der vorstehend beschriebenen Weise kann das Polyolefin nachvernetzt werden, ohne daß das Erzeugnis die vorstehend geschilderten vorteilhaften Eigenschaften verliert.After the product has been produced in the manner described above, the polyolefin can be post-crosslinked without the product losing the advantageous properties described above.
Gemäß einer bevorzugten Ausgestaltung der Erfindung wird im Anschluß an das Eindringen des Kunststoffes bzw. Polyolefins in den porösen Träger eine Lackschicht auf zumindest einer Seite aufgetragen, bevorzugt eine durch Elektronenstrahlung härtbare Lackschicht (ESH-Lack) . Die Aushärtung der Lackschicht bewirkt insgesamt eine Verbesserung der Stabilität und Haftung der Systemkomponenten.According to a preferred embodiment of the invention, following the penetration of the plastic or polyolefin into the porous support, a lacquer layer is applied to at least one side, preferably a lacquer layer curable by electron radiation (ESH lacquer). The curing of the lacquer layer improves the overall stability and adhesion of the system components.
Als poröser Träger kommen auch textilartige Materialien in Betracht.Textile-like materials can also be considered as the porous carrier.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.
Die einzige Figur zeigt schematisch einen porösen Träger 10, eine darauf aufgetragene Dispersionsfarbe 12 und einen darauf aufgebrachten Polyolefinfil 14 in einem Zustand während des Herstellungsverfahrens des Erzeugnisses.The single figure schematically shows a porous carrier 10, an emulsion paint 12 applied thereon and a polyolefin film 14 applied thereon in a state during the manufacturing process of the product.
Der poröse Träger 10 ist beim Ausführungsbeispiel ein Papier (80 g) . Das Papier ist porös und flüssigkeitsdurchlässig. Es wird mit einer sublimierbaren Dispersionsfarbe bedruckt. Die Farbe kann homogen sein oder auch ein grafisches Motiv darstellen, also unter Verwendung verschiedener Farben eine Dekoration beinhalten. Das Papier als poröser Träger 10 kann in herkömmlicher Weise mit dem Farbstoffmotiv bedruckt werden. Das bedruckte Papier wird auf eine als solche herkömmliche Pa- pierbeschichtungsmaschine gespannt und es wird ein Polyolefin als Beschichtungsmaterial aufgetragen. Hierfür können bei der herkömmlichen Beschichtungs aschine geheizte Zylinder dienen, z. B. bei Temperaturen von 200° C bis 260° C. Es handelt sich insoweit beim Aufbringen des Polyolefins auf das bedruckte Papier um eine Extrusionstechnik.In the exemplary embodiment, the porous carrier 10 is paper (80 g). The paper is porous and permeable to liquids. It is printed with a sublimable emulsion paint. The color can be homogeneous or also represent a graphic motif, that is, it can include a decoration using different colors. The paper as porous carrier 10 can be printed with the dye motif in a conventional manner. The printed paper is clamped onto a paper coating machine which is conventional as such, and a polyolefin is applied as the coating material. For this purpose, heated cylinders can be used in conventional coating machines, e.g. B. at temperatures of 200 ° C to 260 ° C. In this regard, it is an extrusion technique when the polyolefin is applied to the printed paper.
Gute Ergebnisse wurden erzielt durch Aufbringung von 50 g bis 500 g Polyolefin pro qm, optimal waren die Ergebnisse bei etwa 250 g/qm. Durch die Wärmeeinwirkung sickert das Polyolefin durch das Papier und durchdringt dieses homogen. Gleichzeitig diffundieren aufgrund der Wärmeeinwirkung die Dispersionsfarb- stoffe in allen Richtungen durch das Polyolefin. Hierfür werden Temperaturen von 220° C bis 280° C, insbesondere etwa 260° C eingesetzt.Good results were achieved by applying 50 g to 500 g polyolefin per square meter, the results were optimal at about 250 g / square meter. Due to the heat, the polyolefin seeps through the paper and penetrates it homogeneously. At the same time, due to the influence of heat, the disperse dyes diffuse through the polyolefin in all directions. Temperatures of 220 ° C to 280 ° C, in particular about 260 ° C, are used for this.
Nach dem Abkühlen entsteht ein weiches, hervorragend verarbeitbares Folienprodukt mit hoher Stabilität und insbesondere Spaltfestigkeit. Ggf. kann eine Nachvernetzung des Polyolefins durchgeführt werden. Das beim Bedrucken des Papiers erzeugte farbige Motiv geht beim vorstehend beschriebenen Prozeß nicht verloren, d. h. das Folienerzeugnis hat eine dem bedruckten Papier entsprechende farbige Dekoration.After cooling, a soft, easily processable film product is created with high stability and in particular splitting resistance. Possibly. post-crosslinking of the polyolefin can be carried out. The colored motif created when printing on the paper is not lost in the process described above, i. H. the foil product has a colored decoration corresponding to the printed paper.
Eine bevorzugte Weiterbildung des wie vorstehend beschrieben hergestellten Folienproduktes wird dadurch erreicht, daß eine Lackschicht auf einer oder beiden Seiten aufgetragen wird. Bevorzugt wird ein durch Elektronenstrahl härtbarer Lack (ESH- Lack) verwendet und gehärtet. Hierdurch werden die mechanischen Eigenschaften und auch die Verarbeitbarkeit des Folienproduktes wesentlich verbessert. A preferred development of the film product produced as described above is achieved in that a lacquer layer is applied to one or both sides. An electron-curable lacquer (ESH lacquer) is preferably used and cured. This significantly improves the mechanical properties and also the processability of the film product.
