Description

Klebeband, insbesondere Wickelband Adhesive tape, in particular wrapping tape
Beschreibung: Description:
Die Erfindung betrifft ein Klebeband, insbesondere Wickelband zum Umwickeln von Kabeln im Automobilen, mit einem textilen Träger, und mit einer Klebebeschichtung auf zumindest einer Seite des Trägers. The invention relates to an adhesive tape, in particular winding tape for wrapping cables in automobiles, with a textile backing and with an adhesive coating on at least one side of the backing.
Klebebänder und insbesondere Wickelbänder zum Umwickeln bzw. zum Bandagieren von Kabeln in Automobilen müssen vielfältigen Anforderungen genügen. Hierzu gehört zunächst einmal eine besondere Medienbeständigkeit gegenüber beispielsweise Öl und Benzin. Auch wird eine große Temperaturbeständigkeit gefordert. Tatsächlich sollen solche Wickelbänder typischerweise im Bereich zwischen -50°C bzw. -40°C bis zu +150°C und mehr eingesetzt werden können. Darüber hinaus werden geringe Schallemissionen angestrebt, beispielsweise derart, dass Klappergeräusche eines umwickelten Kabelbaums oder von Kabelbündeln möglichst verhindert werden. Adhesive tapes and in particular wrapping tapes for wrapping or tying cables in automobiles must meet a wide range of requirements. First of all, this includes special media resistance to oil and petrol, for example. A high temperature resistance is also required. In fact, such winding tapes should typically be used in the range between -50 ° C and -40 ° C up to + 150 ° C and more. In addition, low noise emissions are sought, for example in such a way that rattling noises of a wrapped cable harness or of cable bundles are prevented as far as possible.
Ergänzend zu diesen vorbeschriebenen Anforderungen wird oftmals auch eine hohe Abriebbeständigkeit gefordert. Dadurch soll ein Durchscheuern an der Karosserie verhindert werden. Die Abriebbeständigkeit lässt sich dabei in Anlehnung an die Norm LV 312 (2009) anhand von Abriebklassen bestimmen und das Klebeband kann auf diese Weise entsprechend klassifiziert werden. In addition to these requirements, high abrasion resistance is often required. This is to prevent chafing on the body. The abrasion resistance can be determined based on the LV 312 (2009) standard using abrasion classes and the adhesive tape can be classified accordingly.
Zu den beschriebenen Anforderungen tritt oftmals noch die Forderung hinzu, das fragliche Klebeband bzw. Wickelband manuell einreißen zu können. Denn die fraglichen Wickelbänder werden typischerweise von einem Montagewerker um das entsprechend auszurüstende Kabelbündel beispielsweise spiral- oder wendelförmig herumgewickelt und müssen dann abgelängt werden. Das geschieht am einfachsten durch simples Abreißen. Grundsätzlich ist mit solchen Klebebändern und insbesondere Wickelbändern zum Ummanteln von Kabeln in Automobilen auch eine Längsummantelung möglich und wird ausdrücklich erfindungsgemäß mitumfasst. In addition to the requirements described, there is often the requirement to be able to tear the adhesive tape or wrapping tape in question manually. This is because the winding tapes in question are typically wound around the corresponding bundle of cables, for example in a spiral or helical manner, by an assembly worker and then have to be cut to length. The easiest way to do this is to simply tear it off. Basically, such adhesive tapes and in particular winding tapes for sheathing cables in A longitudinal sheathing is also possible for automobiles and is expressly included according to the invention.
Ein Klebeband des eingangs beschriebenen Aufbaus mit textilem Träger bzw. Gewebeträger wird beispielsweise in der DE 20 2018 103 986 U1 der Anmelderin beschrieben. Vergleichbare Klebebänder mit mehrlagigem Aufbau des Trägers sind Gegenstand der DE 20 2018 101 383 U1 oder auch der DE 20 2018 101 168 U1. An adhesive tape of the construction described at the beginning with a textile carrier or fabric carrier is described, for example, in DE 20 2018 103 986 U1 by the applicant. Comparable adhesive tapes with a multilayer structure of the carrier are the subject of DE 20 2018 101 383 U1 or DE 20 2018 101 168 U1.
In neuerer Zeit werden vermehrt an technische Geräte und insbesondere Automobile sowie folglich auch die darin verbauten Geräte und Einbauteile, zu denen in nicht unerheblichem Maße auch solche Klebebänder und insbesondere Wickelbänder zum Umwickeln von Kabeln in Automobilen gehören, Anforderungen an eine verbesserte Recyclingfähigkeit und insbesondere die ressourcensparende Herstellung gestellt. Da heutzutage Kabelsätze in Automobilen Längen von mehreren Kilometern an Kupfer leitungen aufweisen können, hat sich auch der Verbrauch an entsprechenden Wickelbändern zur Herstellung der Kabelbäume im Vergleich zur Vergangenheit erheblich gesteigert. Dadurch kommt der ressourcensparenden Herstellung eine vermehrte und besondere Bedeutung zu. In recent times, technical devices and in particular automobiles, and consequently also the devices and built-in parts built into them, which to a not inconsiderable extent also include adhesive tapes and in particular winding tapes for wrapping around cables in automobiles, are increasingly demanding requirements for improved recyclability and in particular the resource-saving ones Manufacture posed. Since cable harnesses in automobiles today can have lengths of several kilometers of copper lines, the consumption of appropriate winding tapes for the production of the cable harnesses has increased considerably in comparison to the past. As a result, resource-saving manufacturing is becoming increasingly important.
Zwar werden im Stand der Technik beispielsweise nach der DE 20 2017 106 797 U1 bereits Folien und insbesondere Schutzfolien beschrieben, die zum Teil aus einem biobasierten Polymer hergestellt sind. Das biobasierte Polymer wird seinerseits aus einem pflanzenbasierten Rohstoff gewonnen. It is true that in the prior art, for example according to DE 20 2017 106 797 U1, foils and in particular protective foils are already described, some of which are made from a bio-based polymer. The bio-based polymer is derived from a plant-based raw material.
Vergleichbare Ansätze sind Gegenstand der EP 2 190 909 B1 , die sich mit Verpackungsteilen aus durch Thermoformen von Flachfolienmaterial geformten Kunststoff beschäftigt. Ähnlich geht die US 2011/0152453 A1 oder auch die WO 2013/131158 A1 vor. Schließlich sei in diesem Zusammenhang auch noch auf die EP 2 307 465 B1 verwiesen, die sich mit der Herstellung eines gepfropften Polymers durch Fermentation von nachwachsenden Rohstoffen beschäftigt. Comparable approaches are the subject of EP 2 190 909 B1, which deals with packaging parts made of plastic molded by thermoforming flat film material. US 2011/0152453 A1 or WO 2013/131158 A1 operates in a similar manner. Finally, in this context, too referred to EP 2 307 465 B1, which deals with the production of a grafted polymer by fermentation of renewable raw materials.
Der Stand der Technik hat sich grundsätzlich bewährt, was den Einsatz und die Verwendung von Biopolymeren für insbesondere Folien oder Verpackungs material angeht. Allerdings fehlen bisher belastbare Ansätze dahingehend, Klebebänder und insbesondere Wickelbänder zum Umwickeln von Kabeln in Automobilen ressourcenschonend herzustellen. Hier will die Erfindung insgesamt Abhilfe schaffen. The prior art has proven itself fundamentally as far as the use and use of biopolymers, in particular films or packaging material, is concerned. To date, however, there have been no reliable approaches for producing adhesive tapes and, in particular, winding tapes for wrapping cables in automobiles in a manner that conserves resources. The invention as a whole aims to remedy this.
Der Erfindung liegt das technische Problem zugrunde, ein derartiges Klebeband und insbesondere Wickelband zum Umwickeln von Kabeln in Automobilen so weiter zu entwickeln, dass eine besonders ressourcenschonende Herstellung zur Verfügung gestellt und erreicht wird. The invention is based on the technical problem of further developing such an adhesive tape and in particular winding tape for wrapping cables in automobiles in such a way that a particularly resource-saving production is made available and achieved.
Zur Lösung dieser technischen Problemstellung geht die Erfindung bei einem gattungsgemäßen Klebeband so vor, dass erfindungsgemäß der textile Träger zumindest teilweise unter Rückgriff auf biobasierte Polymere hergestellt ist. Der zumindest teilweise Rückgriff auf biobasierte Polymere bedeutet und drückt aus, dass der Masseanteil dieser biobasierten Polymere im Träger wenigstens 5 Masse-% beträgt. In diesem Fall sind zumindest die besagten 5 Masse-% aus dem biobasierten Polymermaterial hergestellt, das heißt auf Basis erneuerbarer natürlicher Ressourcen. Bei den fraglichen Ressourcen für solche biobasierten Polymere bzw. umgangssprachlich "Biokunststoffe" handelt es sich typischer weise um solche, die auf Rohstoffe zurückgreifen, die vor allem Stärke und Cellulose als Biopolymere von Zuckern aufweisen. Tatsächlich können diese biobasierten Polymere erfindungsgemäß beispielsweise mit Kunststoff- Polymeren gemischt und zur Herstellung des Trägers eingesetzt werden, Bei den letztgenannten Kunststoff-Polymeren handelt es sich um solche, die auf Basis petrochemischer Rohmaterialien und deren Nebenprodukte produziert werden. Demgegenüber kommen für die biobasierten Polymere natürliche Ressourcen zum Einsatz. To solve this technical problem, the invention proceeds in the case of a generic adhesive tape in such a way that, according to the invention, the textile backing is produced at least partially using bio-based polymers. The at least partial recourse to bio-based polymers means and expresses that the mass fraction of these bio-based polymers in the carrier is at least 5% by mass. In this case, at least the said 5% by mass are made from the bio-based polymer material, that is to say on the basis of renewable natural resources. The resources in question for such bio-based polymers or colloquially "bioplastics" are typically those that rely on raw materials that primarily contain starch and cellulose as biopolymers of sugars. In fact, according to the invention, these bio-based polymers can, for example, be mixed with plastic polymers and used to produce the support. The latter plastic polymers are those based on Basis of petrochemical raw materials and their by-products are produced. In contrast, natural resources are used for the bio-based polymers.
In der Regel handelt es sich bei den natürlichen Ressourcen für die biobasierten Polymere um nachwachsende Rohstoffe auf Basis pflanzlicher Materialien. Als Ausgangspflanzen haben sich stärkehaltige Pflanzen wie Mais oder Zuckerrüben sowie Hölzer, aus denen Cellulose gewonnen werden kann, als günstig erwiesen. Weitere Möglichkeiten zur Herstellung greifen auf Pflanzen wie Zuckerrohr, Zuckerrüben, Mais, Korn, Gerste, Kartoffeln, Zuckerpalmen, Maniok, Algen, Ahorn, Agaven, Süßkartoffeln, um nur einige zu nennen, zurück. Grundsätzlich sind auch biobasierte Polymere unter Rückgriff auf Milchsäure denkbar, sogenannte Polylactide. Diese entstehen durch die Polymerisation von Milchsäure, die wiederum ein Produkt der Fermentation aus Zucker und Stärke durch Milchsäurebakterien ist. As a rule, the natural resources for the bio-based polymers are renewable raw materials based on plant materials. Starch-containing plants such as maize or sugar beet and woods from which cellulose can be obtained have proven to be favorable as starting plants. Other production options use plants such as sugar cane, sugar beet, corn, grain, barley, potatoes, sugar palms, cassava, algae, maple, agaves, sweet potatoes, to name just a few. In principle, bio-based polymers using lactic acid are also conceivable, so-called polylactides. These arise from the polymerization of lactic acid, which in turn is a product of the fermentation from sugar and starch by lactic acid bacteria.
Jedenfalls lassen sich die biobasierten Polymere durch natürliche sowie nachwachsende Rohstoffe mit praktisch unendlicher Verfügbarkeit hersteilen, wohingegen die Kunststoff-Polymere auf begrenzte petrochemische Ressourcen zurückgreifen. Um nun das erfindungsgemäße Klebeband insgesamt ressourcenschonend auszulegen, empfiehlt die Erfindung den zumindest teilweisen Rückgriff auf biobasierte Polymere, nämlich im Träger mit einem Masseanteil von wenigstens 5 Masse-%. Der verbleibende Masseanteil von bis zu 95 Masse-% wird in diesem Zusammenhang von Kunststoff- Polymeren geliefert. In any case, the bio-based polymers can be made from natural and renewable raw materials with practically infinite availability, whereas the plastic polymers have limited petrochemical resources. In order to design the adhesive tape according to the invention in a resource-saving manner, the invention recommends at least partial recourse to bio-based polymers, namely in the carrier with a mass fraction of at least 5 mass%. In this connection, the remaining mass fraction of up to 95 mass% is supplied by plastic polymers.
Im Rahmen einer besonders vorteilhaften und ressourcenschonenden Variante wird so vorgegangen, dass der textile Träger vollständig oder nahezu vollständig unter Rückgriff auf biobasierte Polymere mit einem zugehörigen Masseanteil von bis zu 100 Masse-% hergestellt ist. Zu den zuvor beschriebenen Mischformen aus biobasierten Polymeren und Kunststoff- Polymeren gehören natürlich auch Ausführungsformen, bei welchen der textile Träger beispielsweise vollständig auf Basis der biobasierten Polymere hergestellt ist und zusätzlich beispielsweise ein- oder beidseitig eine Folienbeschichtung aufweist. Auch fallen hierunter mehrlagig ausgebildete Träger, bei denen beispielsweise ein textiler Träger auf biobasierte Polymere und der andere textile Träger auf Kunststoff-Polymere zur Herstellung zurückgreift. Dadurch erklären sich die verschiedenen denkbaren Mischformen und auch die sich hierdurch automatisch ergebenden unterschiedlichen Masseanteile. In a particularly advantageous and resource-saving variant, the procedure is such that the textile backing is produced completely or almost entirely using bio-based polymers with an associated mass fraction of up to 100 mass%. To the previous ones Mixed forms of bio-based polymers and plastic polymers described naturally also include embodiments in which the textile carrier is made, for example, entirely on the basis of the bio-based polymers and additionally has, for example, a film coating on one or both sides. This also includes multilayered carriers, in which, for example, one textile carrier uses bio-based polymers and the other textile carrier uses plastic polymers for production. This explains the different conceivable mixed forms and also the automatically resulting different mass fractions.
Das heißt, der Träger kann als monolagiger Träger bzw. einlagig ausgebildet sein. Im Rahmen der Erfindung werden aber auch textile Träger mitberücksichtigt, die als mehrlagiges Laminat ausgelegt sind. Auf diese Weise lässt sich zumindest die Abriebklasse B nach LV 312 (2009) realisieren. Im Rahmen der Abriebklasse B bedeutet dies, dass das betreffende Klebeband mit einem 5 mm Dorn unter Berücksichtigung einer Gewichtsbelastung von 10 N wenigstens 100 Hüben bis zum Durchscheuern widersteht, wie dies beispielhaft in der DE 20 2012 103 975 U1 beschrieben wird. Bevorzugt wird sogar wenigstens die Abriebklasse C erreicht. This means that the carrier can be designed as a monolayer carrier or as a single layer. In the context of the invention, however, textile supports are also taken into account, which are designed as a multilayer laminate. In this way, wear class B according to LV 312 (2009) can be achieved. In the context of abrasion class B, this means that the adhesive tape in question with a 5 mm mandrel, taking into account a weight load of 10 N, withstands at least 100 strokes until it is worn through, as is described, for example, in DE 20 2012 103 975 U1. At least wear class C is preferably even achieved.
Das Klebeband bzw. der Träger verfügt zu diesem Zweck über ein Flächengewicht, welches im Bereich von 20 g/m2 bis 500 g/m2 angesiedelt ist. Bevorzugt wird ein Bereich von 50 g/m2 bis 200 g/m2 für das Flächengewicht des Trägers beobachtet. Die Materialstärke des Trägers liegt dabei meistens unterhalb von 0,8 mm. Bevorzugt werden Stärken des Trägers von weniger als 0,5 mm beobachtet. For this purpose, the adhesive tape or the carrier has a basis weight which is in the range from 20 g / m 2 to 500 g / m 2 . A range from 50 g / m 2 to 200 g / m 2 is preferably observed for the basis weight of the support. The material thickness of the carrier is usually below 0.8 mm. Thicknesses of the support of less than 0.5 mm are preferably observed.
Für die Klebebeschichtung gilt, dass diese im Allgemeinen in einem Auftrags gewicht im Bereich von ca. 20 g/m2 bis 200 g/m2 und insbesondere im Bereich von ca. 50 g/m2 bis 150 g/m2 aufgebracht wird. Als geeignete Kleber haben sich solche auf Basis eines Synthesekautschuk-Klebers, Hotmelt-Klebers oder solche auf Acrylatbasis (mit oder ohne Lösemittel) als besonders günstig erwiesen. Ebenso sind Klebstoffe auf Silikon-, Polyurethan-, Polyether- und Polyolefinbasis denkbar. Die fraglichen Klebstoffe können nach der Beschichtung bei Bedarf vernetzt werden. It applies to the adhesive coating that it generally has an application weight in the range from approximately 20 g / m 2 to 200 g / m 2 and in particular in the range from about 50 g / m 2 to 150 g / m 2 is applied. Suitable adhesives which have been found to be those based on a synthetic rubber adhesive, hotmelt adhesive or those based on acrylate (with or without solvent) have proven particularly advantageous. Adhesives based on silicone, polyurethane, polyether and polyolefin are also conceivable. After coating, the adhesives in question can be crosslinked if necessary.
Die Klebebeschichtung als solche kann vollflächig auf zumindest eine Seite des Trägers aufgebracht werden. Genauso gut ist aber auch eine Streifenbeschichtung aus ein oder mehreren Streifen auf der betreffenden Seite des Trägers denkbar. Darüber hinaus sind Klebstoffe in Pulverform, Dispersionsklebstoffe oder allgemein Klebstoffe auf Lösungsmittelbasis denkbar. Zum Aufbringen des Klebers bzw. der Klebebeschichtung wird im Allgemeinen mit einer sogenannten Direktbeschichtung auf Kontaktbasis gearbeitet. Darüber hinaus ist eine Transferbeschichtung oder auch eine kontaktlose Beschichtung nach der "curtain coating' -Methode denkbar. The adhesive coating as such can be applied over the entire area to at least one side of the carrier. However, a strip coating of one or more strips on the relevant side of the carrier is equally conceivable. Adhesives in powder form, dispersion adhesives or solvent-based adhesives in general are also conceivable. To apply the adhesive or the adhesive coating, a so-called direct coating based on contact is generally used. In addition, a transfer coating or a contactless coating using the "curtain coating" method is also conceivable.
Der textile Träger wird im Allgemeinen unter Rückgriff auf biobasierte Polymerfasern und/oder Polymerfäden gefertigt. Bei den biobasierten Polymerfasern handelt es sich beispielsweise um Stapelfasern, also Fasern endlicher Länge. Es können aber auch Endlosfasern produziert werden, die als Filamente respektive Elementarfaden zur Herstellung des textilen Trägers genutzt werden. Daneben sind auch biobasierte Multifilamentfäden denkbar und werden mitumfasst, also solche, die aus mehreren Endlosfasern bzw. Filamenten hergestellt werden. Die Feinheit der Polymerfäden mag im Bereich von 10 dtex bis zu mehreren 100 dtex angesiedelt sein. Typische Fadenzahlen liegen im Bereich von 10 Fäden/cm bis 50 Fäden/cm bei einem Gewebe. The textile backing is generally manufactured using bio-based polymer fibers and / or polymer threads. The bio-based polymer fibers are, for example, staple fibers, i.e. fibers of finite length. Continuous fibers can also be produced, which are used as filaments or filaments for the production of the textile backing. In addition, bio-based multifilament threads are also conceivable and are included, that is to say those which are produced from a plurality of continuous fibers or filaments. The fineness of the polymer threads may range from 10 dtex to several 100 dtex. Typical thread numbers are in the range of 10 threads / cm to 50 threads / cm for a fabric.
Die einzelnen Fasern respektive Endlosfasern bzw. Filamente werden dabei regelmäßig durch Extrusion produziert. In diesem Zusammenhang ist es auch denkbar, die Fasern respektive Filamente je nach Bedarf farbig auszulegen, indem beim Extrusionsprozess Farbpigmente eingebracht werden. Auch Mischformen der Gestalt lassen sich durch Extrusion realisieren, dass nämlich Granulat biobasierter Polymere mit Kunststoff-Polymeren auf petrochemischer Basis gemischt wird und auf diese Weise quasi Flybridfasern oder Hybridfilamente produziert werden. Auch in diesem Fall genügt der solchermaßen hergestellte textile Träger den Vorgaben, nämlich zumindest teilweise unter Rückgriff auf biobasierte Polymere mit einem Masseanteil im Träger von wenigstens 5 Masse-% hergestellt zu werden. The individual fibers or continuous fibers or filaments are regularly produced by extrusion. In this context it is also it is conceivable to color the fibers or filaments as required by introducing color pigments during the extrusion process. Mixed forms can also be realized by extrusion, namely that granules of bio-based polymers are mixed with plastic polymers on a petrochemical basis and in this way quasi flybrid fibers or hybrid filaments are produced. In this case too, the textile carrier produced in this way satisfies the requirements, namely to be produced at least partially using bio-based polymers with a mass fraction in the carrier of at least 5% by mass.
Bei den biobasierten Polymeren handelt es sich bevorzugt um biobasiertes Polyethylen (PE). Es ist aber auch möglich, andere biobasierte Polymere wie Polylactide (PLA), Polyester des Typs PHA (Polyhydroxyalkanoat), Cellulosematerialien aus chemisch modifizierter Cellulose, PVC (Polyvinylchlorid) aus Bioethanol auf z. B. Zuckerrohrbasis einzusetzen. Ebenso kann auf Bioethanolbasis aus beispielsweise Zuckerrohr Polypropylen bzw. Bio- Polypropylen (PP) genauso wie Bio-Polyethylen hergestellt werden. Daneben sind auch spezifische Polyamide (PA) denkbar, die aus beispielsweise Rizinusöl hergestellt werden. Auch spezifischer Polyester wie beispielsweise PDO (Bio-Propandiol) ist denkbar. Ferner sind weitere biobasierte Polymere wie z. B. PS (Polystyrol), PVA (Polyvinylacetat), PA (Polyamid) sowie Polyurethane möglich. Ebenso fallen natürlich auch etwaige Kombinationen unter die Erfindung. The bio-based polymers are preferably bio-based polyethylene (PE). But it is also possible to use other bio-based polymers such as polylactide (PLA), polyester of the type PHA (polyhydroxyalkanoate), cellulose materials made from chemically modified cellulose, PVC (polyvinyl chloride) from bioethanol on z. B. use sugar cane base. Bioethanol-based can also be used to produce polypropylene or bio-polypropylene (PP), for example, just like bio-polyethylene. In addition, specific polyamides (PA) are also conceivable, which are made from castor oil, for example. Specific polyester such as PDO (bio-propanediol) is also conceivable. Furthermore, other bio-based polymers such. B. PS (polystyrene), PVA (polyvinyl acetate), PA (polyamide) and polyurethanes are possible. Any combinations of course also fall under the invention.
Als geeignete textile Träger haben sich beispielsweise Vlies, Gewirke, Gewebe oder auch Kombinationen als günstig erwiesen. Grundsätzlich sind auch Mischformen beispielsweise der Gestalt denkbar, dass der textile Träger mehrlagig als Kombination GewebeA/lies oder auch Gewebe/Gewebe bzw. Gewebe/Gewirke ausgebildet ist. Der textile Träger kann darüber hinaus verfestigt sein, wie man dies für Träger auf Vliesbasis kennt. Dabei kommen übliche Verfestigungsmethoden wie beispielsweise eine chemische und/oder physikalische Verfestigung zum Einsatz. Bei der chemischen Verfestigung wird das Vlies durch zusätzlich eingebrachtes Bindemittel verfestigt. Die physikalische Verfestigung greift beispielsweise auf eine Vernadelung zurück, die auch mit Hilfe von Wasserstrahlen erfolgen kann. Darüber hinaus kann das betreffende Vlies auch kalandert werden. For example, fleece, knitted fabrics, woven fabrics or combinations have proven to be suitable as suitable textile supports. In principle, mixed forms are also conceivable, for example, in the form that the textile backing is constructed in multiple layers as a combination of fabric / fabric or fabric / fabric or fabric / knitted fabric. The textile backing can also be solidified, as is known for fleece-based backings. Come here Usual consolidation methods such as chemical and / or physical consolidation are used. During chemical consolidation, the fleece is consolidated by an additional binder. The physical consolidation uses needling, for example, which can also be done with the help of water jets. In addition, the fleece in question can also be calendered.
Insgesamt geht die Erfindung von der Erkenntnis aus, dass es bisher nicht für möglich gehalten wurde, dass biobasierte Polymere nicht nur zu Folien oder Verpackungen extrudiert werden können, sondern sich hieraus auch Fasern oder Fäden extrudieren lassen, die dann wiederum zu textilen Trägern als Basis für ein entsprechend aufgebautes Klebeband verarbeitet werden können. Tatsächlich greift die Erfindung in diesem Zusammenhang auf sogenannte "drop-in-Biokunststoffe" zurück, also biobasierte Polymere, deren chemische Struktur mit denen herkömmlicher Kunststoffe identisch ist. Hierzu gehören nur beispielhaft biobasiertes PE (Polyethylen) oder auch biobasiertes PET (Polyethylenterephthalat). Die Grundbausteine dieser biobasierten Polymere werden statt aus Erdöl aus nachwachsenden Rohstoffen hergestellt, wie dies zuvor bereits erläutert worden ist. Aufgrund der identischen chemischen Struktur können für die Weiterverarbeitung zu Endprodukten und folglich auch die in diesem Zusammenhang beschriebenen Klebebändern die gleichen Maschinen und Verfahren genutzt werden, wie sie für die bisher realisierten Kunststoff-Polymere bzw. fossilbasierten Pendants zum Einsatz kommen. Overall, the invention is based on the knowledge that it has not previously been thought possible that bio-based polymers can not only be extruded into films or packaging, but that fibers or threads can also be extruded therefrom, which in turn can then be used as textile bases for an appropriately constructed adhesive tape can be processed. In this context, the invention actually uses so-called “drop-in bioplastics”, that is to say bio-based polymers whose chemical structure is identical to that of conventional plastics. These include, for example, bio-based PE (polyethylene) or bio-based PET (polyethylene terephthalate). The basic building blocks of these bio-based polymers are made from renewable raw materials instead of petroleum, as previously explained. Due to the identical chemical structure, the same machines and processes can be used for further processing into end products and consequently also for the adhesive tapes described in this connection as are used for the previously implemented plastic polymers or fossil-based counterparts.
Beispielsweise wird ein Massenkunststoff wie beispielsweise PET (Polyethylenteraphthalat) durch die Polykondensation aus Monoethylenglykol (oder Ethylenglykol) und Theraphthalsäure hergestellt. Bisher wird lediglich teilweise biobasiertes PET angeboten, bei welchem das Monoethylenglykol (etwa 30 Gew.-%) aus Zuckerrohr-Melasse hergestellt wird. DieFor example, a bulk plastic such as PET (polyethylene terephthalate) is made by polycondensation from monoethylene glycol (or ethylene glycol) and theraphthalic acid. So far, only partially bio-based PET has been offered, in which the monoethylene glycol (approximately 30% by weight) is produced from sugar cane molasses. The
Theraphthalsäure wurde bisher überwiegend petrochemisch produziert. Mittlerweile kann die Theraphthalsäure aber auch wirtschaftlich und biobasiert produziert werden, so dass damit zukünftig auch der Massenmarkt bedient werden kann und dies wirtschaftlich möglich ist. Hierin sind die wesentlichen Vorteile zu sehen. Theraphthalic acid has so far mainly been produced petrochemically. In the meantime, theraphthalic acid can also be produced economically and bio-based, so that the mass market can also be served in the future and this is economically possible. This is where the main advantages can be seen.
