[0002] Adhesive tape for wrapping elongated goods, use of the adhesive tape, system and vehicle

[0003] The present invention relates to the use of an adhesive tape for wrapping elongated goods, an adhesive tape, a system and a vehicle.

[0004] The use of adhesive tapes for wrapping elongated goods is known from the prior art.

[0005] The elongated object can be a single item or composed of several items. For example, in automotive manufacturing, it is common practice to bundle cable sets, i.e., multiple individual cables, by wrapping them together with adhesive tape. The adhesive tape not only serves to join or bundle several items into a single object, but also, by using tapes with a textile backing, to reduce or completely eliminate noise emissions that can otherwise occur when the object comes into contact with parts of the vehicle body or other components.Therefore, these types of adhesive tapes and the objects wrapped with them can be installed in motor vehicles without additional encasing, such as foam, thus reducing costs, manufacturing time, and vehicle weight. However, the advantages provided by the textile backing are not limited to dampening unwanted noise. The wrapped, elongated object can be protected against mechanical stress, such as abrasion, chemical attack, or the effects of high temperatures. Different textile backings are used for different purposes, with the properties of the textile backing being influenced by factors such as the choice of material, fiber design, and / or structure.In other applications, the encasing of the elongated material is used to connect individual elements, such as individual cables or cable strands. This is also known as "basic bundling." To ensure easy and safe handling of the adhesive tapes, they are typically wound onto a roll. This is done, for example, on a core roll, which may or may not be part of the final tape roll. The core is usually made of cardboard or plastic. When winding the tape, it is wound onto the core roll in several turns. The tape can be supplied in fixed lengths, for example, by the meter, or as a continuous roll. Disc-shaped tape rolls are also available, referred to as "pancake" rolls.In this case, the width of the adhesive tape corresponds to the width of the tape roll, since the tape consists of multiple layers and windings that are positioned as precisely as possible on top of each other. Alternatively, the adhesive tape can be wound onto a core, similar to a textile yarn, whose length is significantly greater than the width of the tape. Through the superimposition of a rotational movement of the core and an axial movement of the core or the tape guide element, the adhesive tape initially forms a first, radially innermost layer of helical turns. At the end of the first layer and the transition to the second layer, the orientation of the axial movement is inverted while the rotational movement remains unchanged. At the end of the second layer and the transition to the third layer, the orientation of the axial movement is inverted again, thus reverting to its original orientation, while the rotational movement remains unchanged.The angle of inclination remains constant between each of the orientation reversal points. In this way, numerous winding layers can be formed, the windings of which intersect each other (cross-wound coils).

[0006] Regarding the terminology of spooling technology, reference should be made to the electronic textbook entitled "Technical Information on the Principles of Spooling" by the author Neal Rothwell, published on the Internet since July 1, 2001 by the company "Double R Controls LTD, England".

[0007] There are essentially two ways to use adhesive tape for wrapping elongated goods, especially cable sets.

[0008] In the first method, the adhesive tape is guided around the elongated object in a helical motion. This results in the shape of a helix (also called a screw, helical curve, cylindrical spiral, or helix; a helix is ​​a curve that winds around the surface of a cylinder with a constant slope).

[0009] In the second variant, the elongated component is wrapped axially with the adhesive tape. The wrapping of the cable harness with the described tape is not helical, but rather such that, during wrapping, one longitudinal axis of the tape is essentially parallel to the direction of the cable harness. In cross-section, the adhesive tape lies around the cable harness in the form of an Archimedean spiral. This type of wrapping is also called "wrapping the cable harness."

[0010] Particularly when the adhesive tape does not need to completely encircle the object, i.e., wrap around it without overlapping, it is also advantageous if the width of the adhesive tape is as small as possible, for example between 1 mm and 7 mm, preferably 2 mm to 5 mm. However, a disadvantage is that such narrow rolls of adhesive tape are difficult or impossible to handle and are therefore very rarely used.

[0011] From EP 2 01 1 845 A2, adhesive tape for wrapping cables is known, consisting of a textile carrier and an adhesive compound coated on at least one side, consisting of at least one vinyl aromatic block copolymer and at least a partially hydrogenated adhesive resin.

[0012] The vinyl aromatic block copolymer can be a styrene block copolymer, in particular a hydrogenated block copolymer. As the examples illustrate, the focus is on the use of styrene-isoprene-styrene block copolymer.

[0013] The adhesive tape used there is optimized for the compatibility of the adhesive compound with commercially available cable insulation. Only this property was tested.

[0014] DE 10 2009 041 898 A1 describes an abrasion-resistant woven adhesive tape, which is used in particular for sheathing cable harnesses. The innovation lies in the fact that the ratio of weft threads to warp threads is between 2.2 and 6 and the fabric has a basis weight of at least 110 g / m². 2 This results in high abrasion resistance (class D according to LV 312) while maintaining low flexural stiffness and minimized flagging tendency.

[0015] DE 10 2020 208 549 A1 relates to a process for manufacturing adhesive tape rolls, in which a master roll of adhesive tape is unwound, the web is heated to 80 to 145 °C in a temperature control device and held at this temperature for at least one minute before further processing. This targeted temperature control significantly reduces undesirable emissions such as odor and volatile organic compounds (VOCs) without impairing the adhesive properties or flagging.

[0016] In general, it is desirable to provide adhesive tapes for wrapping elongated goods with high abrasion resistance.

[0017] It is therefore the object of the present invention to provide adhesive tapes that offer a cost-effective solution, simultaneously achieving high abrasion resistance and enabling the particularly simple, inexpensive and quick sheathing of elongated goods such as cable sets in automobiles.

[0018] According to a first aspect of the invention, the aforementioned problem is solved by an adhesive tape with the features of claim 1. The adhesive tape is designed for wrapping elongated materials. The adhesive tape has a carrier, in particular a textile carrier, with a carrier section and an adhesive layer. The carrier section is coated with the adhesive layer. The adhesive layer has an adhesive matrix composed of the rubbers and adhesive resins contained in the adhesive. Optionally, one or more additives such as chalk, antioxidants, or plasticizers such as oil may be added to the adhesive matrix. The adhesive matrix contains styrene-butadiene-styrene in a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive matrix (rubber(s) plus adhesive resin(s)).

[0019] Preferably, the adhesive composition consists only of the adhesive composition base, i.e., it contains only rubber(s) plus adhesive resin(s), wherein styrene-butadiene-styrene is present in a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive composition base.

[0020] Based on 100 parts by weight of the total mass of the adhesive base, additives such as chalk, anti-aging agents or plasticizers such as oil can be added in weights of 1 to 50 parts by weight, preferably 3 to 30 parts by weight, and more preferably 3 to 10 parts by weight.

[0021] Chalk and / or plasticizers are preferably added in amounts of 1 to 10 parts by weight, more preferably 3 to 10 parts by weight, and more preferably 4 to 6 parts by weight. Anti-aging agents are preferably added in amounts of 0.1 to 10.0 parts by weight, more preferably 0.5 to 5.0 parts by weight, and more preferably 1.0 to 2.0 parts by weight.

[0022] Preferably, the term "adhesive tape" as used in the present invention includes all planar structures such as films or film sections extended in two dimensions, tapes with extended length and limited width, tape sections, and the like, ultimately also die-cut pieces or labels. The adhesive tape preferably has a longitudinal extent and a lateral extent. The adhesive tape also preferably has a thickness extending perpendicular to both extents, wherein the lateral and longitudinal extents are many times greater than the thickness. The thickness is preferably as uniform as possible, preferably exactly uniform, over the entire planar extent of the adhesive tape as defined by its length and width. The adhesive tape is preferably in roll form. A roll is preferably understood to be an object whose length is many times greater than its width and whose width remains approximately, preferably exactly, the same along its entire length.Preferably, the adhesive tape can be manufactured in the form of a roll, i.e., wound onto itself in the form of an Archimedean spiral. Preferably, the adhesive tape has a first side, which can also be called the front, and a second side opposite the first, which can also be called the back, in the direction along which the thickness is measured. A backing lacquer (functional layer) can be applied to the back of the adhesive tape to favorably influence the unwinding properties of the tape wound into the Archimedean spiral. This backing lacquer can be formulated with silicone or fluorosilicone compounds, as well as with polyvinylstearyl carbamate, polyethyleneiminestearyl carbamate, or organofluorochemicals as adhesive substances.

[0023] As already described, the adhesive tape is designed for wrapping elongated goods. Preferably, the elongated goods are a cable set, a cable harness, or a cable string, or comprise a cable set, or comprise a cable harness, or comprise a cable string. Preferably, the adhesive tape is used for wrapping elongated goods, such as cable sets in particular, wherein the adhesive tape is guided around the elongated goods in a helical motion. This results in the shape of a helix (also called a screw, helix, cylindrical spiral, or helical spiral; a helix is ​​a curve that winds around the surface of a cylinder with a constant pitch). Alternatively, preferably, the elongated goods are wrapped with the adhesive tape in such a way that, during wrapping, a longitudinal axis of the adhesive tape is oriented essentially parallel to a direction of travel of the elongated goods. In the wrapped state, i.e.,When the elongated object is wrapped with adhesive tape, the tape, viewed in cross-section, particularly in a plane perpendicular to the longitudinal axis, is arranged around the object in the form of an Archimedean spiral. Preferably, the adhesive tape lies against the object, at least in sections. This type of wrapping can also be called "wrapping the cable harness".

[0024] As already described, the adhesive tape has a backing material that includes the backing section. Preferably, the backing material is a textile. More preferably, the backing material, especially a textile, consists of polyester, particularly polyethylene terephthalate, polyamide, or a mixture of polyester such as polyethylene terephthalate and polyamide. Preferably, the backing material is a woven or knitted fabric, such as a spacer fabric, a double-weave fabric, or a nonwoven fabric, which is particularly not bonded with a chemical binder, such as a needle-punched nonwoven. Preferably, the fabric is a polyester fabric, particularly a polyethylene terephthalate fabric (PET fabric). Preferably, the fabric is a polyamide fabric or a blend of polyester and polyamide. The abrasion resistance can be further improved by using polyamide fabric and polyamide.Using polyester fabric and polyester, particularly abrasion-resistant and temperature-resistant carriers can be provided, which is of particular importance for the specific application of bundling cables in automobiles and, for example, in the engine compartment.

[0025] Particularly preferred fabrics are structured as follows:

[0026] • the thread count in the warp is 10 to 60 / cm

[0027] • the thread count in the weft is 10 to 40 / cm

[0028] • the warp threads have a yarn weight between 40 and 400 dtex, in particular between 44 and 330 dtex, most preferably 167 dtex

[0029] • the weft threads have a yarn weight between 40 and 660 dtex, in particular between 44 and 400 dtex, most preferably 167 dtex

[0030] According to a further advantageous embodiment of the invention, the number of threads in the warp is 40 to 50 / cm, preferably 44 / cm.

[0031] According to a further advantageous embodiment of the invention, the thread count in the weft is 18 to 22 / cm, preferably 20 / cm.

[0032] Preferably, the carrier consists of a velour. Preferably, the carrier is a non-woven fabric, in particular an open non-woven fabric.

[0033] Advantageously, and at least in certain areas, the carrier can have a surface that is ground smooth on one or both sides, preferably a fully ground smooth surface on each side. The ground smooth surface may be chintzed, as is explained in detail, for example, in EP 1 448 744 A1.

[0034] Furthermore, the beam can be calendered in a rolling mill for compaction. Preferably, the two rolls rotate in opposite directions and at the same circumferential speed, so that the beam is pressed and compacted.

[0035] If the peripheral speed of the rollers differs, the carrier is additionally ground smooth. The carrier section is preferably a single section of the carrier, wherein the carrier has one or more further sections in addition to the carrier section. Alternatively, preferably, the carrier consists of the carrier section, such that the carrier has no further section in addition to the carrier section.

[0036] Suitable starting materials for the carrier include, in particular, (chemical) fibers (staple fibers or continuous filaments) made of synthetic polymers, also called synthetic fibers, such as polyesters like polyethylene terephthalate, polyamide, polyimide, aramid, polyolefin, polyacrylonitrile, or glass; (chemical) fibers made of natural polymers such as cellulosic fibers (viscose, modal, lyocell, cupro, acetate, triacetate, cellulon), such as rubber fibers, such as plant protein fibers and / or such animal protein fibers; and / or natural fibers made of cotton, sisal, flax, silk, hemp, linen, coconut, or wool. Preferably, the present invention is not limited to the aforementioned materials; rather, a multitude of other fibers can be used to produce the nonwoven fabric, as can be seen by those skilled in the art without requiring any inventive step.

[0037] Yarns made from the specified raw materials are also preferred and suitable. In woven or non-woven fabrics, individual threads may be made from a blended yarn, meaning they contain both synthetic and natural components. However, the warp and weft threads are generally made from a single type of fiber.

[0038] Polyester is the preferred material for the carrier due to its excellent resistance to aging and its superior resistance to chemicals and operating fluids such as oil, gasoline, antifreeze, etc. Furthermore, polyester has the advantage of being a very abrasion-resistant and temperature-resistant carrier, which is particularly important for the specific application of bundling cables in automobiles and, for example, in the engine compartment.

[0039] Preferably, the basis weight of the carrier is between 30 g / m². 2 and 300 g / m² 2still preferably between 50 g / m² 2 and 200 g / m² 2 , particularly preferably between 50 g / m² 2 and 150 g / m² 2 , especially preferred between 70 g / m² 2 and 130 g / m² 2 .

[0040] According to a particularly advantageous embodiment of the invention, a woven fabric or a nonwoven fabric made of polyester is used as a carrier, having a basis weight between 50 g / m² 2 and 150 g / m² 2The adhesive tape has the following features: As already described, the backing section is coated with the adhesive layer. Preferably, the backing section is coated with the adhesive layer such that the tape is a single-sided adhesive tape. Alternatively, preferably, the backing section is coated with the adhesive layer such that the tape is a double-sided adhesive tape. The adhesive can be applied longitudinally along the tape in the form of a strip that is narrower than the backing. Depending on the application, several parallel strips of adhesive can also be coated onto the backing material.

[0041] The position of the strip on the carrier is freely selectable, although an arrangement directly on one of the edges of the carrier is preferred.

[0042] Preferably, the carrier section is completely coated with the adhesive layer.

[0043] As previously described, the adhesive layer consists of the adhesive compound, which contains the adhesive base and optionally one or more additives. Preferably, the adhesive layer consists of the adhesive base. Alternatively, and more preferably, the adhesive layer consists of the adhesive base and one additive. Alternatively, and more preferably, the adhesive layer consists of the adhesive base and several additives. The properties of the adhesive layer can be specifically adjusted using the additive(s).

[0044] As previously described, the adhesive base contains styrene-butadiene-styrene (SBS) at a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive base. This SBS content of 20.0 to 55.0 wt.% based on the total mass of the adhesive base ensures improved abrasion resistance of the adhesive tape. In particular, it has been surprisingly found that when the SBS content of 20.0 to 55.0 wt.% based on the total mass of the adhesive base, the abrasion resistance of the adhesive tape exceeds 1500 cycles. The abrasion resistance of the adhesive tape can also be referred to as its abrasion resistance.In particular, the abrasion resistance of the adhesive tape (measured in the number of strokes, which will be described in detail later) can be significantly improved compared to cases where the adhesive either contains no styrene-butadiene-styrene or contains styrene-butadiene-styrene in a proportion of 20.0 to 55.0 wt.% of the total mass of the adhesive matrix. Preferably, the adhesive matrix comprises, in addition to styrene-butadiene-styrene, another component, in particular another resin component or another rubber component, or the adhesive matrix comprises, in addition to styrene-butadiene-styrene, several other components, in particular one or more other resin components and / or one or more other rubber components.

[0045] In summary, it can be stated that the present invention ensures a high abrasion resistance of the adhesive tapes.

[0046] In one embodiment, the adhesive base comprises styrene-butadiene-styrene in a proportion of 21.4 to 50.0 wt.% based on the total mass of the adhesive base. This styrene-butadiene-styrene content of 21.4 to 50.0 wt.% based on the total mass of the adhesive base ensures particularly high abrasion resistance of the adhesive tape. Specifically, when the adhesive contains styrene-butadiene-styrene in a proportion of 21.4 to 50.0 wt.% based on the total mass of the adhesive base, the abrasion resistance of the adhesive tapes exceeds 4900 cycles. In particular, the abrasion resistance of the adhesive tape can be increased in cases where the adhesive compound either contains no styrene-butadiene-styrene or the adhesive compound contains styrene-butadiene-styrene to a proportion outside of 21.4 to 50.0 wt.-% relative to the total mass of the adhesive base structure, can be significantly improved.

[0047] In one embodiment, the adhesive contains styrene-butadiene-styrene at a proportion of 40.0 to 47.0 wt.% based on the total mass of the adhesive matrix. By having styrene-butadiene-styrene at a proportion of 40.0 to 47.0 wt.% based on the total mass of the adhesive matrix, even higher abrasion resistance of the adhesive tape can be ensured. In particular, when the adhesive contains styrene-butadiene-styrene at a proportion of 40.0 to 47.0 wt.% based on the total mass of the adhesive matrix, the abrasion resistance of the adhesive tapes is greater than 9300 cycles. In particular, the abrasion resistance of the adhesive tape can be significantly improved compared to cases where the adhesive compound either contains no styrene-butadiene-styrene or contains styrene-butadiene-styrene in a proportion of 40.0 to 47.0 wt.% based on the total mass of the adhesive compound matrix.

[0048] In one embodiment, the adhesive compound contains styrene-butadiene-styrene in a proportion of

[0049] The adhesive contains styrene-butadiene-styrene in a proportion of 39.2 to 46.9 wt.%, preferably 41.2 to 45.9 wt.%, based on the total mass of the adhesive base. By having the adhesive contain styrene-butadiene-styrene in a proportion of 39.2 to 46.9 wt.%, preferably 41.2 to 45.9 wt.%, based on the total mass of the adhesive base, the abrasion resistance of the adhesive tape is particularly optimized. In particular, when the adhesive contains styrene-butadiene-styrene in a proportion of 39.2 to 46.9 wt.%, preferably 41.2 to 45.9 wt.%, based on the total mass of the adhesive base, the abrasion resistance of the adhesive tapes is greater than 9600 cycles. In particular, the abrasion resistance of the adhesive tape can be improved in cases where the adhesive compound either contains no styrene-butadiene-styrene or contains styrene-butadiene-styrene in a proportion of 39.2 to 46.9 wt.%, preferably 41.2 to 45.9 wt.%.- % relative to the total mass of the adhesive base structure, can be significantly improved.

[0050] In one embodiment, styrene-butadiene-styrene is the only rubber component of the adhesive matrix. Because styrene-butadiene-styrene is the sole rubber component of the adhesive, its production is particularly simple.

[0051] In one embodiment, the adhesive compound base structure comprises an additional rubber component besides styrene-butadiene-styrene. This additional rubber component ensures that the properties of the rubber component of the adhesive can be adjusted more flexibly.

[0052] Furthermore, to improve processability, thermoplastic elastomers can preferably be added to the rubbers at a weight fraction of 10 to 20 wt%, based on the total elastomer content. Particularly suitable examples include the especially biocompatible styrene-isoprene-styrene (SIS) and styrene-butadiene-styrene (SBS) types.

[0053] The adhesive matrix contains an adhesive resin. The presence of this resin in the adhesive matrix ensures that the tackiness of the adhesive layer can be increased. Preferably, the adhesive matrix contains several adhesive resins. Each adhesive resin can also be referred to as a resin.

[0054] The term "tackifier resin" refers, according to the general understanding of those skilled in the art, to an oligomeric or polymeric resin that increases the adhesion, i.e., the inherent stickiness, of the adhesive compared to an otherwise identical adhesive without tackifier resin. The tackifier resin(s) are selected to be miscible (compatible) with the rubber component of the adhesive.

[0055] Preferred adhesive resins in connection with the present invention include, among others, non-hydrogenated, partially or fully hydrogenated resins based on rosin and rosin derivatives, hydrogenated polymers of dicyclopentadiene, non-hydrogenated, partially, selectively or fully hydrogenated hydrocarbon resins based on C5, C5 / C9 or Cg monomer streams, polyterpene resins based on α-pinene and / or β-pinene and / or β-limonene, terpene phenolic resins, and hydrogenated polymers of preferably pure Cs and C9 aromatics. The aforementioned adhesive resins can be used both alone and in mixtures.

[0056] Preferred are terpenephenolic resins and / or terpene resins based on α-pinene and / or β-pinene and / or β-limonene. The use of terpene resins based on α-pinene (Piccolyte A series from Hercules, Dercolyte A series from DRT) is particularly preferred. These pinenes are reacted alone or in combination with phenol or substituted phenols or mixtures thereof. The reaction process is typically a cationic polymerization. This yields terpenephenolic resins with average molar masses of approximately 100 to 10,000 g / mol, preferably 500 to 2,000 g / mol.

[0057] Preferably, the adhesive mass or the adhesive mass base consists only of styrene-butadiene-styrene and other rubber components as well as adhesive resins, and more preferably only of styrene-butadiene-styrene and adhesive resins.

[0058] Further preferably, styrene-butadiene-styrene is the only rubber component of the adhesive and the adhesive has a single adhesive resin, preferably a terpene phenol resin or a terpene resin based on α-pinene and / or β-pinene and / or β-limonene.

[0059] The adhesive compound can contain the usual and well-known additives such as anti-aging agents, whereby the additives are not taken into account when determining the total mass of the adhesive compound base, but are evaluated as aggregates.

[0060] The following are typically used as additives to the adhesive:

[0061] • Plasticizing agents such as plasticizing oils or low molecular weight liquid polymers such as low molecular weight polybutenes • Primary antioxidants such as sterically hindered phenols

[0062] • Secondary antioxidants such as phosphites or thiosynergists (thioethers)

[0063] • Process stabilizers such as C-radical scavengers

[0064] • Light protectants such as UV absorbers or sterically hindered amines

[0065] • Processing aids

[0066] • Network additives

[0067] • Fillers such as fibers, carbon black, zinc oxide, titanium dioxide, micro-solid spheres, solid or hollow glass spheres, silica, silicates, chalk

[0068] The listed substances are not mandatory; the adhesive also works without them being added individually or in any combination, i.e., without additives.

[0069] Other rubber components preferably used are elastomers from the group of natural rubbers and / or synthetic rubbers, as well as blends of natural rubbers and / or synthetic rubbers.

[0070] The natural rubber or natural rubbers can generally be selected from all available qualities such as crepe, RSS, ADS, TSR or CV types, depending on the required purity and viscosity level, and the synthetic rubber or synthetic rubbers from the group of statistically copolymerized styrene-isoprene-styrene rubbers (SIS), butadiene rubbers (BR), synthetic polyisoprenes (IR), butyl rubbers (IIR), halogenated butyl rubbers (XIIR), acrylate rubbers (ACM), ethylene-vinyl acetate copolymers (EVA) and polyurethanes and / or their blends.

[0071] Preferably, the adhesive is a pressure-sensitive adhesive, i.e., an adhesive that allows a permanent bond to almost all substrates even under relatively light pressure and can be removed from the substrate essentially without leaving any residue after use. A pressure-sensitive adhesive is permanently tacky at room temperature, meaning it has a sufficiently low viscosity and high initial tackiness so that it wets the surface of the respective substrate even with minimal pressure. The adhesive's bonding ability is based on its adhesive properties, and its removability on its cohesive properties. Preferably, the adhesive has a bond strength on steel, measured according to the specified method, of 1.5 N / cm to 25 N / cm. The unwind force, measured according to the specified method, of the adhesive tape according to the invention is preferably in the range of 1.0 N / cm to 12 N / cm.

[0072] Advantageously, the total thickness of the applied adhesive is between 20 pm and 500 pm, further advantageously between 30 pm and 250 pm, and particularly advantageously between 40 pm and 100 pm. The application rate of the adhesive is preferably between 40 g / m². 2 and 500 g / m² 2 .

[0073] According to a second aspect of the invention, the aforementioned problem is solved by use with the features of claim 12. The use of an adhesive tape according to the first aspect of the invention for wrapping elongated goods is provided. The features, technical effects, and / or advantages described in connection with the adhesive tape according to the first aspect of the invention also apply, at least analogously, to the use according to the second aspect of the invention, so that a corresponding repetition is omitted here.

[0074] According to a third aspect of the invention, the aforementioned problem is solved by a system with the features of claim 13. The system comprises an adhesive tape according to the first aspect of the invention and an elongated component, wherein the elongated component is sheathed with the adhesive tape. The features, technical effects, and / or advantages described in connection with the adhesive tape according to the first aspect of the invention and the features, technical effects, and / or advantages described in connection with the use according to the second aspect of the invention also apply, at least analogously, to the system according to the third aspect of the invention, so that a corresponding repetition is omitted here. The system can also be referred to as a sheathed elongated component, such as, in particular, a cable assembly sheathed with an adhesive tape according to the first aspect of the invention.According to one embodiment of the invention, the elongated item is a cable strand comprising a bundle of several cables, such as 3 to 1000 cables, preferably 10 to 500 cables, and in particular between 50 and 300 cables.

[0075] According to a fourth aspect of the invention, the aforementioned problem is solved by a vehicle with the features of claim 14. The vehicle comprises the system according to the third aspect of the invention. Preferably, the vehicle is a conventional vehicle with an internal combustion engine, particularly without an electric motor for propulsion. Alternatively, preferably, the vehicle is a hybrid electric vehicle (HEV). Alternatively, preferably, the vehicle is a battery electric vehicle (BEV). A hybrid electric vehicle is a vehicle with a hybrid drive, i.e., an electric vehicle that is driven by at least one electric motor and another energy converter and obtains energy both from its electrical storage (battery) and from an additional fuel carried on board.A fully electric vehicle, also known as an electric car, is powered exclusively by a battery-driven electric motor, also contains a battery, and therefore requires no fossil fuels. The battery can be charged using external power supplies. Especially since the number of electrical wires in all motor vehicles is increasing due to the growing use of electrical components, while at the same time the installation space for cable sets or wiring harnesses is becoming increasingly smaller, particularly in small vehicles, vehicles with systems featuring elongated components sheathed with abrasion-resistant adhesive tapes are particularly advantageous. An elongated component could be, for example, a cable set, a wiring harness, or a collection of electrical wires.The design of electric and hybrid vehicles, in particular, requires more electrical wiring, which can be especially well protected by the present invention and its increased abrasion resistance. The use of electrical voltages above 42 V necessitates additional protection of the wiring, which must also ensure protection in specific accident situations beyond normal vehicle use. The present invention is also advantageous for this application due to its increased abrasion resistance.The features, technical effects and / or advantages described in connection with the adhesive tape according to the first aspect of the invention, the features, technical effects and / or advantages described in connection with the use according to the second aspect of the invention, and the features, technical effects and / or advantages described in connection with the system according to the third aspect of the invention also apply, at least analogously, to the vehicle according to the fourth aspect of the invention, so that a corresponding repetition is omitted here.

[0076] Even though the steps, particularly those relating to the use of the adhesive tape, are described in a specific order, the present invention is not limited to this order. Rather, the individual steps can be carried out in any sensible order, and in particular, at least partially in parallel with one another.

[0077] Due to the excellent suitability of the adhesive tape, it can be used in a sheathing consisting of a covering in which the self-adhesive tape is present at least in one edge area of ​​the covering, and is bonded to the covering in such a way that the tape extends over one of the longitudinal edges of the covering, preferably in an edge area that is narrow compared to the width of the covering.

[0078] Such a product, as well as optimized embodiments thereof, are disclosed in EP 1 312 097 A1. Further developments for which the adhesive tape according to the invention is also very well suited are described in EP 1 300 452 A2, DE 102 29 527 A1, and WO 2006 / 108871 A1. Likewise, the adhesive tape according to the invention can be used in a method as disclosed in EP 1 367 608 A2.

[0079] Finally, EP 1 315781 A1 and DE 103 29 994 A1 describe embodiments of adhesive tapes that are also possible for the adhesive tape according to the invention.

[0080] To ensure correct application of the adhesive tape, particularly on cable harnesses, at least one longitudinal marking line may be present on the top surface of the backing. Two marking lines are preferred. These marking lines are visually and / or tactilely distinguishable from the surrounding surface.

[0081] The marking is applied to the carrier, for example by printing. Alternatively or additionally, the marking can also be incorporated into the first carrier layer. In this way, the marking can be implemented as a kind of woven warp thread. EP 3 245 265 A1 describes the use of such a marking line on an adhesive tape.

[0082] To make working with the adhesive tape particularly easy for the user, perforations are provided in the tape, which are oriented perpendicular to the direction of travel of the tape and / or arranged at regular intervals.

[0083] The perforation primarily serves as a tear-off aid for cutting the tape to the specified length. The section of tape that wraps around the item should not have any perforations to avoid negatively impacting its shielding properties.

[0084] Perforations can be produced particularly advantageously discontinuously using flat dies or transverse perforation wheels, as well as continuously using rotary systems such as spiked rollers or punching rollers, optionally with the use of a counter roller (Vulkollan roller) that acts as the counter wheel during cutting. Further possibilities include controlled intermittent cutting technologies such as the use of lasers, ultrasound, high-pressure water jets, etc. If, as with laser or ultrasonic cutting, some of the energy is introduced into the substrate material as heat, the fibers can be fused in the cutting area, thus largely preventing disruptive fraying and resulting in sharp cut edges. These latter methods are also suitable for achieving special cutting edge geometries, such as concave or convex edges.

[0085] The adhesive tape is flexible and can be used on different cable diameters.

[0086] The advantageous marking allows for safe and easy verification of the proper application of the adhesive tape.

[0087] The adhesive tape according to the invention can be applied using the known and usual processes for cable wrapping.

[0088] Further features, advantages, and applications of the present invention will become apparent from the following description of the exemplary embodiments and the figures. All features described and / or illustrated, individually and in any combination, constitute the subject matter of the invention, irrespective of their composition in the individual claims or their cross-references. In the figures, the same reference numerals denote identical or similar objects.

[0090] Figure 2 shows a schematic representation of an embodiment of a system according to the invention with the embodiment of the adhesive tape according to the invention shown schematically in Figure 1.

[0091] Figure 3 shows a schematic representation of an embodiment of a vehicle according to the invention with the embodiment of the system according to the invention shown schematically in Figure 2, and

[0092] Figure 4 shows a schematic representation of a setup for a method of measuring abrasion. Figure 1 shows a schematic representation of an embodiment of an adhesive tape 1 according to the invention, Figure 2 shows a schematic representation of an embodiment of a system 3 according to the invention with the embodiment of the adhesive tape 1 according to the invention shown schematically in Figure 1, and Figure 3 shows a schematic representation of an embodiment of a vehicle 5 according to the invention with the embodiment of the system 3 according to the invention shown schematically in Figure 2.

[0093] The adhesive tape 1 has a carrier 7 and an adhesive layer 9. The carrier 7 has a carrier section 11. The carrier section 11 is coated with the adhesive layer 9. The system 3 shown in Figure 2 has the adhesive tape 1 and an elongated object 13. The elongated object 13 is wrapped with the adhesive tape 1. The adhesive tape 1 is thus designed to wrap the elongated object 13. A key aspect of the present invention is the use of the adhesive tape 1 for wrapping the elongated object 13. For the use of the adhesive tape 1 for wrapping the elongated object 13, the adhesive tape 1 and the elongated object 13 are first provided, and then the elongated object 13 is wrapped with the adhesive tape 1.The elongated object 13 has eight cables, each cable 15 being shown as a circle in Figure 2, and each cable 15 of the eight cables extending along a direction of extension of the elongated object 13 perpendicular to the plane of Figure 2. In Figure 2, only one cable 15 of the eight cables is labeled. The vehicle 5 shown in Figure 3 has the system 3.

[0094] The adhesive layer 9 consists of an adhesive, i.e., the adhesive base, and optionally one or more additives. The adhesive base contains styrene-butadiene-styrene (SBS) at a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive base. Because the adhesive layer 9 consists of the adhesive, i.e., the adhesive base, and optionally the additive or additives, and because the adhesive base contains styrene-butadiene-styrene (SBS) at a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive base, the abrasion resistance of the adhesive tape 1 is improved. The abrasion resistance of the adhesive tape 1 can also be referred to as the abrasion resistance of the adhesive tape 1.

[0095] Table 1 shows examples of styrene-butadiene-styrene (SBS) for 21 adhesive layers, designated B1, B2, ..., B21, each forming one adhesive layer 9 of a corresponding adhesive tape 1. These examples are Calprene 7318, Calprene 711, and Globalprene 3566, and are given in wt.% based on the total mass of the adhesive matrix. Table 1 also shows the SBS content (wt.%) for each of the 21 adhesive layers, also in wt.% based on the total mass of the adhesive matrix. Each of the 21 adhesive layers corresponds to one of the 21 adhesive tapes. The adhesive layers B1, B3, B6 to B15, B18, B19 and B21 are each assigned to an embodiment of an adhesive tape 1 according to the invention, since in each of these adhesive layers the adhesive base structure styrene-butadiene-styrene is present in a proportion of 20.0 to 55.0 wt.-% based on the total mass of the adhesive base structure, and the adhesive layers B2, B4, B5, B16, B17 and B20 are each assigned to an example of a comparison adhesive tape, since in each of these adhesive layers the adhesive either contains no styrene-butadiene-styrene, as is the case with adhesive layers B4 and B5, or the adhesive contains styrene-butadiene-styrene to a proportion of outside 20.0 to 55.0 wt.% based on the total mass of the adhesive base structure, as is the case with adhesive layers B2, B16, B17 and B20.

[0096] Calprene 7318 is an example of a styrene-butadiene-styrene (SBS). The adhesive layers B1 to B3, B6 to B10, and B13 to B20 shown in Table 1 consist exclusively of Calprene 7318 as the SBS. Calprene 7318 is an example of a SBS copolymer, preferably with a diblock content of 80 wt.%. SBS can also be referred to as styrene-butadiene-styrene, styrene-butadiene-styrene, or SBS. Calprene 711 is another example of a SBS copolymer. The adhesive layer B11 shown in Table 1 contains only Calprene 711 as the styrene-butadiene-styrene. Calprene 711 is an example of a styrene-butadiene-styrene copolymer. Globalprene 3566 is another example of a styrene-butadiene-styrene.The adhesive layer B12 shown in Table 1 consists exclusively of Globalprene 3566 as the styrene-butadiene-styrene. Globalprene 3566 is an example of a styrene-butadiene-styrene copolymer, specifically a styrene-butadiene-styrene block copolymer.

[0097] Furthermore, examples of other rubber components, namely SIS Sol T190 and NR V145, are shown for the adhesive layers B1 to B21, each in wt.% based on the total mass of the adhesive base.

[0098] SIS Sol T190 is an example of an additional rubber component that the adhesive may contain besides styrene-butadiene-styrene. The adhesive layer shown, which contains SIS Sol T190 (adhesive layer B4), does not contain styrene-butadiene-styrene. Adhesive B4 contains SIS Sol T190 as the sole rubber component of the adhesive matrix. SIS Sol T190 is an example of a styrene-isoprene-styrene block copolymer, which may also be referred to as styrene-isoprene-styrene block copolymer, styrene-isoprene-styrene block copolymer, styrene-isoprene-styrene block copolymer, or SIS block copolymer.

[0099] NR V145 is also an example of an additional rubber component that the adhesive may contain besides styrene-butadiene-styrene. Adhesive layers B2, B3, B5, and B18 to B20 contain NR V145. Adhesive layers B2, B3, and B18 to B20 contain NR V145 in addition to styrene-butadiene-styrene. Thus, adhesive layers B2, B3, and B18 to B20 contain an additional rubber component, namely NR V145, in addition to styrene-butadiene-styrene. Adhesive layer B5 does not contain styrene-butadiene-styrene. Adhesive layer B5 contains NR V145 as its only rubber component. NR V145 is an example of a polyisoprene, which can also be called polyisoprene, which in turn is an example of a natural rubber, which can also be called "natural rubber".

[0100] Furthermore, examples of adhesive resins, namely Dercolyte A115 and Dertophene T, and plasticizing agents, namely an oil Pionier 2070P and a liquid resin Wingtack 10, are shown for the adhesive layers B1 to B21, each in wt.% based on the total mass of the adhesive base.

[0101] Dercolyte A115 is an example of a resin that can contain the adhesive compound. The adhesive layers B7 to B10 and B18 to B20 shown each contain Dercolyte A115. Dercolyte A115 is an example of a polyterpene resin, which can also be referred to as a "polyterpene resin". Dertophene T is another example of a resin that can contain the adhesive compound.

[0102] The adhesive layers B1 to B6 and B11 to B17 shown each contain Dertophene T. Dertophene T is an example of a terpene phenolic resin, which can also be described as a "terpene phenolic resin".

[0103] Furthermore, examples of additives are shown for adhesive layers B1 to B21, namely an antioxidant, Irganox 1520L, a chalk component, MS40 chalk, an oil, Pionier 2070P, and a liquid resin, Wingtack 10, each in parts by weight per 100 parts by weight of the adhesive base. Pionier 2070P is an example of an oil that the adhesive may contain. Adhesive layers B8 and B9 contain Pionier 2070P. Pionier 2070P is an example of a medical-grade white oil, which can also be referred to as paraffin oil or "liquid paraffin."

[0104] Wingtack 10 is an example of a plasticizer that the adhesive may contain. The illustrated adhesive layer B10 contains Wingtack 10. Wingtack 10 is an example of a room-temperature liquid hydrocarbon resin, also known as a hydrocarbon resin, specifically an aliphatic C5 petroleum hydrocarbon resin.

[0105] Irganox 1520L is an example of an additive in the form of an antioxidant that the adhesive may contain in addition to the adhesive matrix. The adhesive matrix, together with the additive and, if applicable, another additive or additives, forms the adhesive layer 9. All illustrated adhesive layers B1 to 21 contain Irganox 1520L.

[0106] Chalk MS40 is an example of an additive in the form of a chalk component that the adhesive may contain in addition to the adhesive base. The adhesive base, together with the additive and possibly another additive or additives, forms the adhesive layer 9. The adhesive layer B6 contains Chalk MS40. Chalk MS40 is an example of a component consisting of calcium carbonate, which can also be referred to as "calcium carbonate".

[0107] In addition to SBS, B21 also contains SIS as a rubber component. The wt% of SBS in the total mass of the adhesive base is 26.2%, resulting in high abrasion resistance.

[0108]

[0109] Table 1

[0110] As previously described, each adhesive tape 1 has the carrier 7 with the carrier section 11. Three adhesive tapes or comparison tapes were produced for each of the adhesive layers B1 to B21 shown in Table 1. For each adhesive tape or comparison tape, the respective adhesive layer 1 to 21 shown in Table 1 was applied with a mass of 65 g / m². 2 on a textile substrate of type PET (polyethylene terephthalate) fabric with a basis weight of 130 g / m² 2 In the present case, 3 x 15, and thus 45, adhesive tapes according to the invention (with adhesive layers B1, B3, B6 to B15, B18, B19 and B21) and 3 x 6, and thus 18 comparison adhesive tapes (with adhesive layers B2, B4, B5, B16, B17 and B20) were produced. The adhesive tapes and comparison tapes thus produced were tested for abrasion resistance according to ISO 6722.

[0111] Table 1 shows, for each embodiment of the adhesive tape 1 according to the invention, to which a corresponding adhesive layer 9 of adhesive layers B1, B3, B6 to B15, B18, B19 and B21 is assigned, and for each comparison adhesive tape, to which a corresponding adhesive layer 9 of adhesive layers B2, B4, B5, B16, B17 and B20 is assigned, the styrene-butadiene-styrene content (SBS content) already shown in Table 1, in each case in % based on the total mass of the adhesive base layer, as well as an abrasion resistance. The adhesive layers are shown in % according to increasing SBS content.The abrasion resistance shown for each adhesive layer is derived from an average of three abrasion resistances, where each abrasion resistance of the three abrasion resistances was determined using one adhesive tape 1 of three identically constructed adhesive tapes or using one comparison adhesive tape of three identically constructed comparison adhesive tapes.

[0112] Based on the presented compositions of the adhesive layers and the presented abrasion resistances for the adhesive tapes with adhesive layers B1, B3, B6 to B15, B18, B19 and B21 and abrasion resistances for the comparison adhesive tapes with adhesive layers B2, B4, B5, B16, B17 and B20, it can be concluded that if the adhesive layer 9 consists of the adhesive base and optionally one or more additives, and the adhesive base is styrene-butadiene-styrene in a proportion of 20.0 to 55.0 wt.-% based on the total mass of the adhesive base, the abrasion resistance of the adhesive tape 1 (measured as the number of strokes, which will be described in detail later) can be significantly improved compared to cases where the adhesive either contains no styrene-butadiene-styrene, as is the case with adhesive layers B4 and B5, or contains styrene-butadiene-styrene at a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive base, as is the case with adhesive layers B2, B16, B17, and B20. In particular, it has been found that when the adhesive contains styrene-butadiene-styrene at a proportion of 20.0 to 55.0 wt.% based on the total mass of the adhesive base, the abrasion resistance of the adhesive tapes is greater than 1500 strokes. Furthermore, it has been found that when the adhesive mass contains styrene-butadiene-styrene in a proportion of 21.4 to 50.0 wt.This effect is particularly pronounced when the adhesive contains styrene-butadiene-styrene (SBS) at a wt.% of the total mass of the adhesive base. Specifically, when the adhesive contains styrene-butadiene-styrene at a wt.% of the total mass of the adhesive base, the abrasion resistance of the adhesive tapes exceeds 4900 cycles. Furthermore, when the adhesive contains styrene-butadiene-styrene at a wt.% of the total mass of the adhesive base, the abrasion resistance of the adhesive tape can be further increased. Specifically, when the adhesive contains styrene-butadiene-styrene at a wt.% of the total mass of the adhesive base, the abrasion resistance of the adhesive tapes exceeds 9300 cycles. Furthermore, the abrasion resistance of the adhesive tape 1 can be particularly optimized if the adhesive compound contains styrene-butadiene-styrene in a proportion of 39.2 to 46.9 wt.-%, preferably from 41.2 to 45.9 wt.% based on the total mass of the adhesive base. When the adhesive contains styrene-butadiene-styrene at a proportion of 39.2 to 46.9 wt.%, preferably from 41.2 to 45.9 wt.% based on the total mass of the adhesive base, the abrasion resistance of the adhesive tapes is greater than 9600 cycles.

[0113] In some of the adhesive layers under consideration, namely layers B1 and B6 to B17, styrene-butadiene-styrene (SBS) is the sole rubber component. Because SBS is the only rubber component, the adhesive is particularly easy to manufacture. In some of the adhesive layers under consideration, namely layers B2, B3, and B18 to B20, the adhesive contains an additional rubber component besides SBS. This additional rubber component allows for more flexible adjustment of the properties of the rubber component in the adhesive. Furthermore, all adhesive layers under consideration contain an adhesive resin.The inclusion of the adhesive resin in the adhesive ensures that the tack of adhesive layer 9 can be increased. The adhesive layers B1 to B21 were prepared from solution. For this purpose, the respective raw materials were added to a glass container in the appropriate ratio. A solvent mixture of gasoline and toluene was then added to achieve a solids content of 20% and 40% by weight, respectively. The mixtures containing exclusively synthetic rubbers are produced with a solids content of 40% by weight. Due to the significantly higher molecular weight of natural rubber, the mixtures containing natural rubber are produced with a lower solids content of 20% by weight. The mixtures were then placed on a rolling mill for at least three days to ensure that all raw materials were homogeneously dissolved.The dissolved adhesive solutions were coated onto a 36 pm PET transfer film using a coating table, resulting in a basis weight of 65 g / m² when dried. 2 This was achieved. These samples were then dried in an oven at 120 °C for 15 minutes. Subsequently, the corresponding adhesives were applied to the fabric of the respective textile substrate using a laminating machine. Applying the adhesive to the fabric using the laminating machine can also be described as coating the substrate section 11 with the adhesive layer 9.

[0114] Alternatively, alternative compounds with the compositions of adhesive layers B1 to B21 can be produced using a hot melt process. In this process, the corresponding raw materials are metered into a planetary roller extruder in the appropriate ratio and compounded at elevated temperature to create a homogeneous compound. The resulting material is then formed to achieve a basis weight of 65 g / m². 2 The coating process takes place on a coating line between two calender rollers. The fabric is then coated directly inline via a pressure roller.

[0115] Although the steps, particularly those relating to the use of adhesive tape 1, are described in a specific order, the present invention is not limited to this order. Rather, the individual steps can be carried out in any meaningful sequence, and in particular, at least partially in parallel with one another.

[0116] It should be further noted that "having" does not exclude any other elements or steps, and "a" or "an" does not exclude a plurality. It should also be noted that features described with reference to one of the above embodiments may also be used in combination with other features of other embodiments described above. Reference numerals in the claims are not to be considered as a limitation.

[0117] Conducting the tests

[0118] Unless explicitly stated otherwise, measurements are carried out under a test climate of 23 ± 1 °C and 50 ± 5 % relative humidity.

[0119] Abrasion resistance of an adhesive tape

[0120] The testing and classification of adhesive tapes for cable sheathing in the automotive industry is carried out according to comprehensive standards such as VW 60360-3 "Protection systems for wiring harnesses in motor vehicles, test requirements for hoses" (2019-05), BMW GS 95008-3-1 "Protection systems for wiring harnesses in motor vehicles, adhesive tapes, requirements, tests", or ES-KU5T-1 A303-AA rev. E (2017 / 06) "Harness Tape Performance Specification". These standards will be referred to below as the VW, BMW, and Ford specifications, respectively.

[0121] The abrasion resistance of adhesive tapes and protective tubing is also determined according to a defined test procedure according to BMW and VW. The classification of adhesive tapes and tubing with regard to their abrasion resistance is shown in Table 2 (Classification of abrasion resistance of adhesive tapes according to BMW GS 95008-3-1) for a mandrel diameter of 5 mm. Adhesive tapes and tubing are classified according to the same abrasion classes, whereby tubing can additionally be tested at elevated ambient temperatures (see Table 3: Classification of abrasion resistance of tubing according to VW 60360-3).

[0122] Table 2: Classification of abrasion resistance of adhesive tapes according to BMW GS 95008-3-1

[0123]

[0124] Table 3: Classification of abrasion resistance of hoses according to VW 60360-3

[0125] Abrasion resistance was determined according to the international standard ISO 6722 (in particular ISO 6722-1:2011 (E), section 5.12.4.2, 9.3 "Scrape abrasion"). The adhesive tapes and comparison tapes were each adhered to a metal mandrel. These prepared metal mandrels can also be referred to as test specimens. Each test specimen, and thus each adhesive tape 1 and each comparison tape, was subjected to stress with a thin steel wire under defined stroke geometries and weight loads until the corresponding adhesive tape 1 or comparison tape was worn through and a short circuit occurred, stopping a running counter.

[0126] All abrasion resistance data refers to the ISO 6722 method. Each adhesive tape (1) and each comparison tape was applied in a single layer lengthwise to the corresponding 10 mm diameter metal mandrel. The abrasion movement was performed centrally on the adhesive tapes and comparison tapes under a weight load of 7 N. A 0.45 mm diameter steel wire was used as the friction element. The number of strokes until short circuit was specified as the measure of abrasion resistance. One stroke corresponds to one back-and-forth movement.

[0127] A test specimen 103, 10 cm long, is wrapped in a single layer around a 10 mm thick steel mandrel 102 in the longitudinal direction of the product to be tested and placed in a specimen holder 101. The test specimen 103 is fixed by a hold-down device 104. A steel wire 105 with a diameter of 0.45 mm serves as the abrasion tool. Under a weight load of 7 N (generated by a support weight 106), the wire rubs centrally against the test specimen 103. A drive 108 moves the steel wire back and forth in a cyclical motion 107 parallel to the axis of the steel mandrel 102. The number of strokes required to destroy the test specimen 103 is determined as a measure of its abrasion properties. By measuring the abrasion resistance, the resistance to sharper objects, such as a metal edge, can be simulated in practical applications. A setup for a method of abrasion measurement is shown in Figure 4.

[0128] Determination of adhesive strength on steel

[0129] To measure the adhesive strength on steel, 19 mm wide test strips are adhered bubble-free to a finely sanded (FEPA grit 240) stainless steel plate and pressed down with a rubber-wrapped 2 kg roller at a speed of 10 m / min. The steel plate and the protruding end of the adhesive tape are then clamped into the ends of a tensile testing machine so that a pull-off angle of 180° is created. The adhesive tape is pulled off the steel plate at a speed of 300 mm / min. The adhesive strength is expressed in N / cm.

[0130] Determination of the rolling force

[0131] The tape's unwinding force is measured according to DIN EN 1944 (1996-04) at a peel speed of 300 mm / min.
