Description

The invention relates to the use of an adhesive tape for sheathing elongate material, in particular cable sets.For some time, adhesive tapes have been used in industry for producing cable harnesses. The adhesive tapes are used for bundling a multiplicity of electrical lines before installation or in an already mounted state, in order, for example, to reduce the space requirement of the line bundle by banding and additionally to achieve protective functions such as protection against mechanical and / or thermal stress. Common forms of adhesive tapes comprise film or textile supports which are generally coated on one side with pressure-sensitive adhesives. Adhesive tapes for enclosing elongate articles are known, for example, from EP 1 848 006 A2, DE 10 2013 213 726 A1, and EP 2 497 805 A1.Current cable strands wound with adhesive tape are generally not sufficiently shaping and dimensionally stable. However, this is often undesirable for manufacturing reasons. During production, the cable strands are generally prefabricated to form a cable plan and then inserted into the object to be fitted, such as automobiles, for example. A cable harness plan corresponds to the actual spatial arrangement of the individual cable strands in the cable harness, that is to say which cable strand is bent at which point at which angle where positions of branches or bonds are located and with which plugs the ends of the cable strands are occupied.In order to keep the individual strands of the cable set in a specific shape, so that they can be guided, for example, in doors and trunk flaps, injection molded parts or plastic or rubber guides, referred to below as guides, are usually subsequently applied around the cable harness wound with adhesive tape. However, these injection molded parts and guides have the disadvantage that additional material and assembly costs are incurred. Particularly in the case of injection-molded parts, the main task is to position them securely at a desired location, so that these parts usually have very low flexibility. However, in the transitions from rigid to movable components such as doors, trunk lids, electrically pivotable exterior mirrors, some flexibility is necessarily required to fully maintain the functions of the movable components.WO 2015 / 004190 A1 discloses a method for sheathing elongate material such as, in particular, lines or cable sets, in which the elongate material is sheathed in a helical line or in the axial direction with an adhesive tape having curable adhesive applied thereto, and the adhesive applied to the adhesive tape is cured by supplying radiation energy such as heat. For thermal curing, a temperature of 175° C. is used.A disadvantage of this method is the high curing temperature, which is not very practicable in the automobile industry, for example, when cable strands are assembled during the manufacturing process, in particular because the cable insulations often made of PVC can be damaged. Consequently, cable plans have hitherto only been laid in prefabricated injection moulds. This is associated with high production costs.Therefore, adhesive tapes are desirable which cure at at most 110° C., preferably at most 100° C., more preferably at about room temperature, so that the covering of adhesive tapes can be integrated in the production processes of the cable harnesses or cable plans. After curing, the adhesive tapes must have the requisite requirements for dimensional stability and flexibility. On the other hand, the adhesives must not cure already during storage, since otherwise they can no longer be used.DE 100 39 982 A1 discloses adhesive tapes for the sheathing of elongate material, comprising a nonwoven carrier having a basis weight of from 20 g / m 2 to 80 g / m 2 and a pressure-sensitively adhesive, non-curing silicone adhesive, these adhesive tapes having to fulfil, as a further function, the bundling and permanent fixing of the individual cables to form a cable harness.It is therefore an object of the present invention to provide an adhesive tape for coating elongate material which meets the requirements described above.To solve the technical problems, the use of an adhesive tape for covering elongate material is proposed, comprising a tape-shaped carrier which is coated on at least one side with a tin-free silicone elastomer composition curable at room temperature, the uncured composition having a Williams plasticity of 100 to 350 at 25° C., preferably 100 to 250 at 25° C.According to one embodiment of the invention, the elongate material is a cable harness which comprises a bundle of a plurality of cables, such as 3 to 1000 cables, preferably 10 to 500 cables, in particular between 50 and 300 cables.According to the invention, the tin-free room temperature curable silicone elastomer composition is a kit comprising the following components: a) a terminal base polymer comprising a polysiloxane or a mixture of polysiloxanes having a viscosity of at least 150,000 mPas at 25°C and terminal di-(C 2-4)- alkoxysilyl groups, b) 2 to 20 parts by weight per 100 parts by weight of the base polymer of a particulate reinforcing filler; c) 30p to 50p parts by weight per 100 parts by weight of the base polymer of a particulate non-reinforcing filler, where ρ is the average density of the particulate non-reinforcing filler; d) a crosslinking catalyst selected from the group consisting of organic titanium oxides and organic zirconium oxides.Such room temperature curable silicone elastomer compositions are described in WO 2018 / 109425 A1 and WO 2018 / 109493 A1, which is fully incorporated herein by reference.The base polymer may comprise one or more polymers of the general formula: -[-S i( R 1)( R 2)- O-]- wherein R 1 and R 2 are independently selected from linear or branched (C 1-6)- alkyl groups, linear or branched (C 2-6) - alkenyl groups, linear or branched (C 2-4) - haloalkyl groups and phenyl groups as described in WO 2018 / 109425 A1. For example, R 1 and R 2 may be independently selected from a methyl group, an ethyl group, a trifluoromethyl group, a 2,2,2-trifluoroethyl group, a 3,3,3-trifluoropropyl group and a 4,4,4-trifluoropropyl group. The base polymer may comprise a hydroxy-terminal polysiloxane or a mixture of hydroxy-terminal polysiloxanes. The hydroxy-terminal polysiloxanes may have the general formula: HO-[-Si(R 1)( R 2)- O-] n-[- Si(R 1)( R 2)- OH, wherein R 1 and R 2 are as described above and n is selected such that the hydroxy-terminal polysiloxane or the mixture of hydroxy-terminal polysiloxanes has a viscosity of at least 150 000 mPas at 25° C. The viscosity of the base polymer is preferably from 150,000 mPas to 1,000,000 mPas, more preferably 250,000 mPas to 500,000 mPas, as described in WO 2018 / 109425 A1.The di-(C 2-4)- terminal alkoxysilyl groups may have the general formula: -SiR a( OR b)( OR c) wherein R a is selected from linear or branched (C 1-10) - alkyl groups, linear or branched (C 2-8) - alkenyl groups, a (C 6-10)- aryl group, each of the aforementioned groups being independently substituted with one or more of a halogen group, a cyano group, an amyl group, a -NHR e- group, a -NR e Rf group, a -OeR group, a -C(=O)R e- group, a carboxyl group, a glycidyl group and a sulfanyl group, wherein R b and R c are independently selected from linear or branched (C 2-4) - alkyl groups and R e and R f are independently selected from linear or branched (C 1-6)- alkyl groups, as described in WO 2018 / 109425 A1. For example, R a may be a methyl or vinyl group, and R b and R c may independently be an ethyl group, an n-propyl group or an isopropyl group.The organic titanium oxides and organic zirconium oxides may be represented by the general formula: M(OR g)a( R h)4-a wherein M is titanium or zirconium, each R g is independently a linear or branched (C 1-12)- alkyl group, and each R h is independently a ligand having the general formula R'-(-O-)=CH-C (=O)-R", wherein R' and R" are each independently a linear or branched (C 1-6)- alkyl group or a linear or branched (C 1-6) - alkoxy group, and n is an integer from 0 to 4, as described in WO 2018 / 109425, A1.The crosslinking catalyst may be selected from, for example, diisobutoxy bis(ethyl acetate) titanate, titanium diisobutoxy bis(acetylacetonate), titanium diisopropoxide bis(acetylacetonate), titanium diisopropoxide bis(ethylacetoate) and dibutoxy bis(acetylacetonate).The at least one particulate reinforcing filler preferably has a B.E.T. surface area of at least 60 m 2 / g, for example 60 m 2 / g to 450 m 2 / g, more preferably 80 m 2 / g to 150 m 2 / g. The particulate reinforcing filler is preferably selected from talc, calcium carbonate, calcium silicate, mica, barium sulfate, precipitated silica and mixtures thereof.The at least one particulate non-reinforcing filler may comprise a filler having a needle-like structure, preferably having an average particle length (L50) of at least 5 μm, such as 5 μm to 90 μm, preferably 10 μm to 30 μm. The particulate non-reinforcing filler is preferably an inorganic mineral filler, for example selected from table spar (wollastonite), aluminum borate and mixtures thereof.The filler having a needle-like structure may be present in amounts of, for example, 20 wt.% to 75 wt.% based on the total weight of the at least one particulate non-reinforcing filler, as described in WO 2018 / 109425 A1.The curable silicone elastomer composition may further contain adhesion promoters, stabilizers, fibrous fillers and / or colorants, as described in WO 2018 / 109425 A1.The curable silicone elastomer composition, which acts here as a matrix polymer, forms a self-supporting three-dimensional film (wherein the spatial extent in the thickness direction of the film is generally very much smaller than the spatial extents in the longitudinal and transverse directions, i.e. than in the two spatial directions of the surface extent of the film; for the meaning of the term "film", see also further below in this respect).The curable silicone elastomer composition is moldable in the uncured state. In the cured, shaped state, it remains flexible and, after a stress (deflection, bending), resumes the shaped geometry.The supports used may be all known films and textile supports such as knits, laid scrims, belts, braids, needled pile textiles, felts, woven fabrics (comprising canvas, twill and atlas weave), knitted fabrics (comprising warp knit and knit) or nonwovens, where "nonwoven" is to be understood as meaning at least textile planar structures according to EN 29092 (1988), and stitch-bonded nonwovens and similar systems. Particularly advantageous is an adhesive tape in which a woven fabric, a nonwoven fabric or a knitted fabric is used as the carrier. Such supports are described, for example, in WO 2015 / 004190 A1, which is fully incorporated herein by reference.Furthermore, spacer fabrics and knitted fabrics with lamination can be used. Spacer fabrics of this type are disclosed in EP 0 071 212 B1. Spacer fabrics are mat-shaped layered bodies with a cover layer made of a fiber or filament fleece, a backing layer and individual or tufts of holding fibers present between these layers, which are needled through the particle layer distributed over the surface of the layered body and connect the cover layer and the backing layer to each other.Suitable nonwovens are particularly consolidated staple fiber nonwovens, but also filament, meltblown and spunbonded nonwovens, which are usually additionally to be consolidated. Mechanical, thermal and chemical consolidation are known as possible consolidation methods for nonwovens. Nonwovens have proven to be particularly advantageous which are consolidated in particular by oversewing with separate threads or by mesh. Such consolidated nonwovens are produced, for example, on stitch-bonded machines of the "Malimo" type from Karl Mayer, formerly Malimo, and can be obtained, inter alia, from Hoptex Group AG.As the support, a kunit or multiknit nonwoven fabric can be further used. A spun-knit nonwoven fabric is characterized in that it results from the processing of a longitudinally oriented nonwoven fabric into a planar structure which has stitches on one side and stitches on the other, but has neither threads nor prefabricated planar structures. Such a nonwoven is also produced for a long time, for example on stitch-bonded machines of the "Malimo" type from Karl Mayer.A multiknit nonwoven is characterized in comparison with the kunit nonwoven in that the nonwoven experiences consolidation by puncturing on both sides with needles both on the top side and on the bottom side. As a starting product for a multiknit, one or two unidirectionally meshed nonwoven pile fabrics produced by the Kunit process are generally used. In the end product, both nonwoven fabric top sides are formed into a closed surface by fiber mesh and are connected to one another by virtually perpendicular fibers. The additional introducible of further pierceable sheet materials and / or spreadable media is provided.Finally, stitch-bonded webs are also suitable as a precursor for forming a carrier according to the invention and an adhesive tape according to the invention. A stitched nonwoven is formed from a nonwoven material having a plurality of seams running parallel to one another. These seams are formed by sewing in or stitch-knitting continuous textile threads. For this type of nonwoven, stitch-bonded machines of the "Malimido" type are known from Karl Mayer.Needle-punched fleeces are also particularly suitable. In needle punch fleece, a fibrous web becomes a sheet structure with the aid of barbed needles. By alternating puncturing and pulling out of the needles, the material is consolidated on a needle bar, whereby the individual fibers become entangled to form a solid sheet structure.Furthermore, a staple fiber fleece which is preconsolidated in the first step by mechanical processing or which is a wet fleece which has been laid hydrodynamically, wherein between 2 wt. % and 50 wt. % of the fibers of the fleece are fusible fibers, in particular between 5 wt. % and 40 wt. % of the fibers of the fleece. Such a nonwoven is characterized in that the fibers are wet laid or, for example, a staple fiber nonwoven is preconsolidated by forming meshes of fibers of the nonwoven by needle punching, sewing, air and / or water jet processing. In a second step, heat setting takes place, the strength of the nonwoven being increased again by the melting or fusing of the fusible fibers.Advantageously and at least in regions, the carrier has a smooth-ground surface on one or both sides, preferably a smooth-ground surface over the entire surface. The smooth-ground surface may be machined, as explained, for example, in EP 1 448 744 A1. In this way, the repellency of dirt is improved.As starting materials for the support, in particular (chemical) fibers (staple fiber or continuous filament) made of synthetic polymers, also called synthetic fibers, made of polyester such as 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 vegetable egg white fibers and / or such as animal egg white fibers and / or natural fibers made of cotton, sisal, flax, silk, hemp, linen, coconut or wool are provided. However, the present invention is not limited to the materials mentioned, but rather, it is possible, as recognized by the person skilled in the art without having to be carried out according to the present invention, to use a large number of further fibers for producing the nonwoven.Furthermore, yarns made from the indicated raw materials are also suitable. In fabrics or laid scrims, individual filaments can be made from a mixed yarn, i.e., they can have synthetic and natural constituents. As a rule, however, the warp threads and the weft threads are each embodied in a single type.Polyester is preferably used as the material for the carrier, because of the excellent ageing resistance and the excellent media resistance to chemicals and operating agents such as oil, gasoline, antifreeze and the like. Furthermore, polyester has the advantage that it leads to a very abrasion-resistant and temperature-resistant carrier, which is of particular importance for the specific application for bundling cables in automobiles and, for example, in the engine compartment.Advantageously, the basis weight of the textile carrier is between 30 g / m 2 and 300 g / m 2 further advantageously between 50 g / m 2 and 200 g / m 2, particularly advantageously between 50 g / m 2 and 150 g / m 2, very particularly advantageously between 70 g / m 2 and 130 g / m 2.According to a particularly advantageous embodiment of the invention, a woven or nonwoven fabric made of polyester is used as the carrier, which woven or nonwoven fabric has a weight per unit area of between 50 g / m 2 and 150 g / m 2.Advantageously, the mass application of the silicone elastomer composition applied to the carrier and / or introduced into the carrier is between 30 g / m 2 and 400 g / m 2, further advantageously between 100 g / m 2 and 250 g / m 2, particularly advantageously between 100 g / m 2 and 200 g / m 2. According to one embodiment of the invention, the mass application in the case of woven textiles and nonwovens is between 50 g / m 2 and 400 g / m 2, more advantageously between 100 g / m 2 and 250 g / m 2, more advantageously between 100 g / m 2 and 200 g / m 2 and in the case of films between 30 g / m 2 and 400 g / m 2, more advantageously between 50 g / m 2 and 250 g / m 2, more advantageously between 70 g / m2and 200 g / m2.The ready-coated material is preferably cut to a width of 20±2 mm (any other width is also conceivable) and, when used for wrapping elongate material, wound spirally with an overlap of 50% around the elongate material-such as a cable bundle.The ready-coated material is preferably provided with a protective film.The invention relates to the use of an adhesive tape which is used in flexible shaping. The use at transitions from rigid to movable components is particularly advantageous, since a high and recurring stress acts on the cable harness at these positions, which frequently leads to fatigue of the cable sheathing. The use of curable silicone elastomer compositions in the adhesive tape enables a controlled deflection of the entire cable harness. The curable silicone elastomer composition thereby ensures that the cable sheaths do not experience direct friction at the transitions from rigid to movable components. A further advantage of the invention is that, due to the desired restoring force of the curable silicone elastomer composition, the cable strands experience only a minimally necessary deflection, so that the entire cable strand is exposed to less load than, for example, when bellows are used.The invention relates to the use of an adhesive tape for sheathing elongate material, such as in particular lines or cable sets, wherein an adhesive tape as described above is guided in a helical line around the elongate material or the elongate material is sheathed in the axial direction by the adhesive tape, the elongate material together with the sheathing adhesive tape is brought into the desired arrangement, in particular into the cable set plan, the elongate material is held in this arrangement, while the curable silicone elastomer composition is caused to cure by the supply of moisture.The tape is preferably spirally wound around the elongate material with an overlap of 30% to 70%, more preferably 40 to 50%, in particular about 50%.The williams plasticity (W.P.) is determined by the method described in WO 2018 / 109425 A1.Examples:Example 1 - Preparation of an Adhesive TapeFor the preparation of the curable silicone elastomer composition, 100 parts by weight of a hydroxy terminated polydimethylsiloxane having a viscosity of 400,000 mPas at 25°C is functionalized with 2.45 parts vinyl triethoxy silane to give a terminal polysiloxane having a terminated vinyl triethoxy siloxane group. This compound was mixed with 15.5 parts poly(dimethyl siloxane) treated fumed silica (Cabosil™ TS720), 82.7 parts (first grade) talc (Magsil™ D200), 26.1 parts (second grade) talc (Magsil™ 2628c), 10.8 parts Sil-Cell™ 35 / 34, 1.03 parts 3-glycidyloxypropyltriethoxysilane (GLYEO), 1.94 parts Diisobutoxybisethylacetoacetatotitanat 2.45 parts methyltriethoxysilane (MTES), and 0.52 parts HTV red pigment (Holcosil™).The curable silicone elastomer composition described above was pressed out with the aid of a press at 22° C. and a pressure of about 150 bar between a fluorosilicone-coated 50 μm PET film and a 220 μm thick PET fabric carrier to give a film having a thickness of about 500 μm, using a 220 μm thick PET fabric carrier having a weight per unit area of 130 g / m 2. Subsequently, the material was cut into strips having a width of 20 mm.Example 2 - Bending Test for Determining StiffnessA test pattern consisting of 250 individual lines having a line cross section of 0.35 mm 2, was bundled to a pattern line set using a 9 mm wide adhesive tape (tesa 51618), so that the pattern line set had a diameter of 23±5 mm and a length of 300±50 mm. This pattern line set was spirally wound with the stiffening material, ensuring 50% overlap. Subsequently, the stiffening material was cured by means of moisture.The cured pattern lead set was subjected to a bending test to determine the effect of the stiffening material on stiffness. The bending test was carried out on a tensile testing machine. For this purpose, the pattern line set was placed on two jaws at a distance of 70 mm and pressed and loaded centrally with a pressure fin around a distance of 30 mm. The force required for the deformation of the measurement path was recorded in Newton by a tensile testing machine. The test speed was 100 mm / min both at the load and at the load relief of the pattern line set. The test was performed at 3 different locations of the line set (beginning, middle and end). The bending force results from the average of the three individual measurements and was evaluated in three categories as follows:Rating categories 3-point Bending Test: + well suited for application (250-350 N) O restrictedly suited for application (200-250 N and 350-400 N) - not suited for application (<200 and >400 N)For comparison, a commercially available adhesive tape, tesa ®51036, was subjected to the same experiment. The results are shown in Table 1 below.Example 3 - C-Shape Test for Determining Stiffness at Different TemperaturesA test method was developed for determining the rigidity of a bent cable pattern (C cable pattern bending test). To produce a C cable pattern (see FIG. 1 ), a cable line ( 10) having a line cross section of 0.35 mm is wound 2100 times around a holder ( 1) to form a pattern line set. The holder (1) comprises two opposed semicircular guides (2, 3) with a diameter of 120 mm, spaced apart by a distance (A) of about 210 mm. The wound cable set is shown in FIG. 1.The number of cable windings is 100. A pattern line set with a diameter of 15±5 mm and a circumference of 690 mm is produced. At the vertices of the semicircular segments and at two straight line sections (legs) in each case, the cable bundle (10) is tied together and fixed by cable ties (4, 5, 6, 7, 8, 9) with a tensile force of 210±10 N, such that the cable bundle (10), after removal from the holder, has sufficient rigidity to not deform. In order to further improve the rigidity of the cable bundle (10), a support (11) is positioned between the legs of the cable bundle and is likewise fixed by cable ties.The cable bundle (10) produced in this way is removed from the holder and wound around with the adhesive tape to be tested (width 19 mm-20 mm) with a 50% overlap. For this purpose, the winding is started on a cable tie (e.g. 6 or (7)) of the leg in the direction of a segment of a circle ((6)->(4) or (7)->(5)). When the winding reaches the cable tie (4) or (5) at the apex of the semi-circular segment, it is removed and the winding is continued until the next cable tie ((4)->(8) or (5)->(9)) of the opposite leg. The same procedure is also carried out on the other side, on the other semicircular segment.The samples thus prepared are subjected to the corresponding crosslinking method (moisture). With a side cutter, the patterns adjacent to the remaining cable ties are cut to obtain two "C-shaped" cable (C-cable) patterns each having an un-wrapped portion on both sides of the semi-circular wrapped portion. The section is made at a distance of the diameter (120 mm) from the apex of the semi-circular segment, projected onto the center of the circle.Loops are tied to the leg ends of the patterns with a length of cable to allow it to be suspended at one end and a weight to be suspended at the other end. The remaining cable ties are now removed, since they can distort the test result. The distance between the legs is now determined.One of the two samples is stored at room temperature and the other at 60° C.A 1 kg weight is suspended on the respective lower leg of the "C-test piece". After one hour, the deflection of the cable bundle is noted (deflection behavior at RT or 60° C. for 1 h) and the weight is removed. After one minute, the deflection is determined again (restoring behavior for 1 min at RT or 60° C.). After one hour, the deflection is then determined again and recorded (restoring behavior at RT or 60° C. for 1 h).The determined C-shape deformation values were classified into three categories, well suited for application, limitedly suited for application, and not suitable for application. Categories were evaluated as follows:Evaluation categories of C-shape bending test (room temperature and 60° C.): + well suited for application (30-70% deflection) O restrictedly suited for application (>15-30%) - not suitable for application (<15%)Evaluation categories of C-shape bending test (recovery behavior at RT and 60° C.): + well suited for application (>50% deflection) ◯ restrictedly suited for application (30-50%) - not suitable for application (<30%)For comparison, a commercially available adhesive tape, tesa ®51036, a PET woven tape with an acrylate adhesive composition, was subjected to the same experiment. The results are also shown in Table 1 below. Table 1: Table 1:Formulation from Example 1+++tesa® 51036◯--C.
