Definitions

  • Adhesive tape in particular wrapping tape
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • these bio-based polymers can, for example, be mixed with plastic polymers and used to produce the support.
  • plastic polymers are those based on Basis of petrochemical raw materials and their by-products are produced.
  • natural resources are used for the bio-based polymers.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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%.
  • 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.
  • the carrier can be designed as a monolayer carrier or as a single layer.
  • textile supports are also taken into account, which are designed as a multilayer laminate.
  • wear class B according to LV 312 (2009) can be achieved.
  • 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.
  • 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.
  • the adhesive coating 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.
  • the adhesive coating as such can be applied over the entire area to at least one side of the carrier.
  • 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.
  • a so-called direct coating based on contact is generally used.
  • a transfer coating or a contactless coating using the "curtain coating” method is also conceivable.
  • 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.
  • 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.
  • the individual fibers or continuous fibers or filaments are regularly produced by extrusion.
  • 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.
  • 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.
  • the bio-based polymers are preferably bio-based polyethylene (PE).
  • PE polylactide
  • 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.
  • specific polyamides (PA) are also conceivable, which are made from castor oil, for example.
  • Specific polyester such as PDO (bio-propanediol) is also conceivable.
  • other bio-based polymers such.
  • PS polystyrene
  • PVA polyvinyl acetate
  • PA polyamide
  • polyurethanes any combinations of course also fall under the invention.
  • fleece, knitted fabrics, woven fabrics or combinations have proven to be suitable as suitable textile supports.
  • 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.
  • 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.
  • the fleece in question can also be calendered.
  • 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.
  • 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.
  • 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.
  • 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.
