Definitions
- the invention relates to a method for producing an adhesive tape and to an apparatus for carrying out the method for producing the adhesive tape.
- Adhesive tapes have long been used in industry for the production of wiring harnesses.
- the adhesive tapes are used for bundling a plurality of electrical lines before installation or already mounted state, to reduce the space requirement of the trunk group by bandaging and to achieve additional protection functions.
- an adhesive tape with a textile support is known, on one side of which a pressure-sensitive adhesive is applied, and the pressure-sensitive adhesive is built up from a dried, polymer-acrylate-crosslinked polymer acrylate dispersion.
- the acrylate dispersion includes monomeric acrylates and ethylenically unsaturated co-monomers that are not acrylates.
- the pressure-sensitive adhesive additionally contains between 10 and 100% by weight of a tackifier. In this case, an aqueous acrylate dispersion is first applied to the support and then dried.
- EP 2 695 926 A1 discloses adhesive tapes for covering cables with a carrier and a dried polymer dispersion applied to one side of the carrier, the polymer being composed of 95 to 100% by weight of ethyl acrylate and / or two ethylhexyl acrylate 0, 0 to 5.0% by weight of an ethylenically unsaturated monomer having an acid or acid anhydride function.
- the problem with applying the polymer dispersion to the textile support is the fact that low-viscosity polymer dispersions penetrate through the support. This creates the problem that, on the one hand, a great deal of polymer dispersion must be used in order to achieve a full-surface application on one textile side; on the other hand there arises the problem that when the dried adhesive tape is wound into a roll, the individual layers stick together and make unwinding impossible.
- a band-shaped carrier is provided.
- the aqueous dispersion adhesive and the thickener come into contact with each other after or during application. Subsequently, the dispersion adhesive is dried.
- the thickening takes place only on the textile support.
- one side of the band-shaped textile carrier is coated with a thickener, and then an aqueous dispersion adhesive is applied to the thickener. Subsequently, the dispersion adhesive is dried. "Thereafter” means that the thickener is first applied to one side of the textile support and then the aqueous dispersion adhesive is applied to the thickener at the same point in time
- the thickener can be applied immediately before the aqueous dispersion adhesive so that the thickener has a thickener (short) period of time, in particular 1 to 10 s, before the thickener strikes the aqueous dispersion adhesive At the moment of impact, the dispersion adhesive begins to thicken, so that its viscosity increases prevented.
- one side of the textile support is coated with a thickener and applied to another side of the textile support, an aqueous dispersion adhesive. Subsequently, the dispersion adhesive is dried. In this case, the thickener is pressed through the textile support, or the thickener flows through the textile support by gravity.
- the thickener and the aqueous dispersion adhesive are applied simultaneously in this advantageous variant.
- the invention makes use of the idea of not immediately applying and drying a high-viscosity dispersion adhesive to one side of the support layer to thereby produce an adhesive tape which can be wound up. Since highly viscous dispersion adhesives are difficult to handle, they must be pressed through a slot die under high pressure and first advanced through a line system to the nozzle. The processing of a high viscosity dispersion adhesive involves high pressure generation.
- the invention makes use of the idea of applying a thickener and an aqueous dispersion adhesive to a textile support.
- the dispersion adhesive thickened immediately and preferably abruptly, so that the thickened dispersion adhesive can penetrate only very little in the textile carrier and in particular can not penetrate this.
- thickener and dispersion adhesive are applied to the same side of the textile support, the side of the textile support facing away from the application side remains completely dry, that is, intact from both the thickener and the aqueous dispersion adhesive. After drying the thickened, applied dispersion adhesive, the adhesive tape can be easily wound up.
- the thickener is applied over the entire surface of the textile support. Further preferably, the dispersion adhesive is also applied over the entire area on the full thickness thickener.
- the method according to the invention can have several variants.
- the thickener can be applied over the entire surface of the textile support, while the dispersion adhesive is partially coated, in particular in one or more running in the machine direction strips.
- the thickener can be partially applied, wherein the dispersion adhesive is then coated only in areas in which the thickener is applied. Further preferably, thickener and dispersion adhesive are applied in one or more MD strips, wherein the strips of thickener are preferably of greater width than the strips of dispersion adhesive. It has been shown that when certain thickener variants are used in the metered addition in low-viscosity dispersion adhesives at the point where the thickener meets the dispersion adhesive surface, the viscosity increases sharply.
- a double-slot die is used to apply the thickener and the aqueous dispersion adhesive; it can preferably have a slot width (also referred to as height) of 20 to 700 ⁇ m, in particular 50 to 500 ⁇ m, more particularly 100 to 300 ⁇ m, and a length, which corresponds to the width of the textile carrier; while lengths between 10 to 4000 mm, preferably between 1000 and 2000 mm are used, but all other nozzle lengths are conceivable.
- two individual slot nozzles can be used, which are arranged on one and the other side of the textile support.
- the textile carrier is guided around a casting roll and rests with a side facing away from the order side on the casting roll and is advanced by rotational movements of the casting roll.
- a double slit nozzle is preferably provided on the adhesive side of the textile carrier, the feed rate of the textile carrier and a slot spacing of the double slit nozzle being selected such that the aqueous dispersion adhesive is in turn only about one to 10 ms after the thickener has been applied to the textile carrier the thickener is applied.
- the thickener can not penetrate through the textile carrier, and by applying the aqueous dispersion adhesive, the thickener is prevented from further penetrating the textile carrier, but thickens the dispersion adhesive.
- a low penetration of the dispersion adhesive and the thickener in the textile support is desired, so that the dispersion adhesive and the textile carrier form a firm connection with each other.
- After thickening the dispersion adhesive it is dried and a pressure-sensitive adhesive tape is produced, which can be wound up.
- a dispersion adhesive with a viscosity of 0.2 Pa * s to 30 Pa * s ⁇ 5 Pa * s, especially from 0.5 Pa * s to 15 Pa * s used ⁇ 5 Pa * s. More preferably, the viscosity of the dispersion adhesive is between 2 to 5 Pa * s. It is particularly advantageous if the thickener has a similar or the same viscosity as the dispersion adhesive.
- the viscosity measurement is carried out with an ARES (Rheometric Scientific) rheometer at room temperature and at a shear rate of 100 s -1 with a 50 mm diameter cone and plate system.
- ARES Heometric Scientific
- the device is suitable for carrying out the abovementioned processes or the processes listed below.
- the device comprises a casting shaft having a casting shaft longitudinal direction and a double slot nozzle having a gap longitudinal direction which is arranged along the casting shaft longitudinal direction, preferably both longitudinal directions are arranged parallel to one another.
- a first slot nozzle and a second slot nozzle may be arranged on one side of a textile carrier, or they may be arranged opposite one another on the one and the other side of the textile carrier. Between the Doppelschlitzdüse and the casting shaft, a free space is provided which forms a kind of gap through which a textile support can be advanced.
- the textile carrier is deflected around the casting shaft and provided with a feed by the casting shaft or other means.
- a feed direction of the textile carrier is arranged transversely, preferably perpendicular to the longitudinal direction of the casting shaft and / or the double slot nozzle.
- a first slot nozzle of the double slot nozzle is provided with a feed device with a thickener, the slot nozzle being in fluid-conducting connection with the feed device with the thickener.
- the thickener is provided in a reservoir and is passed through a piping system, which is part of the supply device, to the first slot nozzle and applied from there to a casting shaft facing away from the side of the textile support.
- a second slot nozzle of the double slot nozzle communicates with a second feeder with an aqueous dispersion adhesive.
- the second slot nozzle is also part of the double slot nozzle and is in fluid communication with the second supply means with a reservoir for the dispersion adhesive in combination.
- the first slot nozzle is arranged in the feed direction in front of the second slot nozzle. This ensures that the thickener is first applied to the side of the textile carrier facing away from the casting shaft by the first slot nozzle and immediately thereafter applied by the second slot nozzle of the dispersion adhesive to the provided with the thickener textile carrier.
- a drying device for an adhesive tape is provided in the feed direction after the double-slit nozzle.
- the drying device extracts the water from the aqueous dispersion adhesive and thus dries the dispersion adhesive on the textile support.
- the choice of dispersion adhesives and thickener will be described in the context below.
- the method according to the invention is used in particular for producing an adhesive tape, in particular for wrapping cables, from a preferably textile carrier and from a pressure-sensitive adhesive applied on at least one side of the carrier in the form of a dried polymer dispersion, the polymer being composed of:
- the polymer consists of 95.0 to 99.5% by weight of n-butyl acrylate and / or 2-ethylhexyl acrylate and 0.5 to 5% by weight of an ethylenically unsaturated monomer having an acid or acid anhydride function, more preferably 98 , 0 to 99.0 wt .-% of n-butyl acrylate and / or 2-ethylhexyl acrylate and 1, 0 to 2.0 wt .-% of an ethylenically unsaturated monomer having an acid or acid anhydride function.
- the pressure-sensitive adhesive composition may additionally be admixed with the residual monomers mentioned below in addition to the tackifiers and / or additives mentioned below, such as light stabilizers or anti-aging agents, in the amounts also mentioned below.
- the polymers of the pressure-sensitive adhesive consist only of the monomers (a) and (b) in the stated proportions.
- n-butyl acrylate forms the monomer (a).
- Suitable monomers (b) are, for example, acrylic acid, methacrylic acid, itaconic acid, maleic acid, fumaric acid and / or maleic anhydride.
- R 3 H or CH 3 , preferably the mixture of acrylic acid or methacrylic acid is preferably used. Particularly preferred is acrylic acid.
- the polymer has the following composition:
- the polymer dispersion is prepared by the process of emulsion polymerization of said components. Descriptions of this process can be found, for example, in: "Emulsion Polymerization and Emulsion Polymers” by Peter A. Lovell and Mohamed S. El-Aasser - Wiley-VCH 1997 - ISBN 0-471 -96746-7 or in EP 1 378 527 B1 In the case of polymerization, it can not be ruled out that not all monomers are converted into polymers, although it is obvious that the residual monomer content should be as small as possible.
- the dispersion adhesive is a pressure-sensitive adhesive, that is to say an adhesive which, even under relatively slight pressure, permits a permanent bond with almost all adhesive properties and, after use, can be removed again from the primer without leaving any residue.
- a PSA acts permanently tacky at room temperature, so has a sufficiently low viscosity and a high initial tack, so that it wets the surface of the respective Klebegrunds already at low pressure.
- the adhesiveness of the dispersion adhesive is based on its adhesive properties and its removability on its cohesive properties.
- the dispersion adhesive must be above its glass transition temperature at the processing temperature to have viscoelastic properties. Since the cable set winding is carried out at normal ambient temperature (approximately between 15 ° C to 25 ° C), the glass transition temperature of the pressure-sensitive adhesive formulation is preferably below +15 ° C (determined by DSC (differential scanning calorimetry) according to DIN 53 765 at a heating rate of 10 K. min).
- DSC differential scanning calorimetry
- the glass transition temperature of the acrylate copolymers can be estimated according to the equation of Fox from the glass transition temperatures of the homopolymers and their relative proportions.
- the quantitative composition of the monomer mixture is advantageously chosen such that according to equation (G1) analogous to the Fox equation (see TG Fox, Bull. Am. Phys 1956, 7, 123) gives the desired TG value for the polymer.
- acrylate copolymers having a glass transition temperature of at most 0 ° C. are preferred.
- the polymers according to the invention have, according to ASTM D3330, an adhesion to steel of at least 1.0 N / cm (with a basis weight of the dispersion adhesive of 30 g / m 2 on a 23 ⁇ m polyester film as support).
- adheresive resin is meant, in accordance with the general understanding of the art, an oligomeric or polymeric resin which increases the autoadhesion (tack, inherent tack) of the pressure-sensitive adhesive compared to the otherwise non-adhesive-containing, but otherwise identical pressure-sensitive adhesive composition This effect is also present when the dispersion adhesive is added up to 15% by weight (corresponding to ⁇ 15 parts by weight) or from 5 to 15% by weight of tackifier (based on the mass of the dried polymer dispersion) Preferably, 5 to 12, more preferably 6 to 10 wt .-% tackifier (based on the mass of the dried polymer dispersion) is added.
- Tackifiers which are also referred to as tackifier resins, in principle all known substance classes are suitable.
- Tackifiers are, for example, hydrocarbon resins (for example polymers based on unsaturated Cs or Cg monomers), terpene-phenolic resins, polyterpene resins based on raw materials such as ⁇ - or ⁇ -pinene, aromatic resins such as cumarone-indene resins or styrene-based or ⁇ -methylstyrene such as rosin and its derivatives, for example disproportionated, dimerized or esterified rosin, for example reaction products with glycol, glycerol or pentaerythritol, to name just a few.
- hydrocarbon resins for example polymers based on unsaturated Cs or Cg monomers
- terpene-phenolic resins polyterpene resins based on raw materials such as ⁇ - or ⁇ -pinene
- aromatic resins such as cumarone-
- resins without readily oxidizable double bonds such as terpene-phenolic resins, aromatic resins and particularly preferably resins which are prepared by hydrogenation, for example hydrogenated aromatic resins, hydrogenated polycyclopentadiene resins, hydrogenated rosin derivatives or hydrogenated polyterpene resins.
- resins based on terpene phenols and rosin esters are also preferred.
- Particular preference is given to resins based on terpene phenols and rosin esters having a softening point above 90 ° C. according to ASTM E28-99 (2009).
- the resins are expediently used in dispersion form. They can be mixed so easily with the polymer dispersion finely divided. Particularly preferred is the variant of the invention in which no adhesive resins are added to the pressure-sensitive adhesive. Surprisingly and unpredictably for the person skilled in the art, the lack of adhesive resins in the adhesive tape does not lead-as the person skilled in the art would expect-to an insufficient bond strength. In addition, the flagging behavior is surprisingly no worse.
- the dispersion adhesive can be diluted with water.
- adhesives based on polyurethane dispersions can also be applied by the process according to the invention.
- Other typical dispersion adhesives are described in the textbook “Bonding - Basics, Technologies, Applications” by G. Habenicht, 2009, Springer Verlag, Berlin / Heidelberg, in Chapter 3.5.
- the proportions of thickener or rheology additives are after the mixing of thickener and dispersion adhesive in the range of 0.1 to 5 wt .-% based on the mass of the dried polymer dispersion.
- the organic thickeners in turn, split into two main principles of action: (i) the thickening of the aqueous phase, ie, not associating, and (ii) associative formation between thickener molecule and particles, in part involving the stabilizers (emulsifiers).
- Representatives of the first (i) group of substances are water-soluble polyacrylic acids and polycoacrylic acids which form polyelectrolytes with a large hydrodynamic volume in the basic medium.
- ASE alkali swellable emulsion
- They are characterized by high perturbation viscosities and severe shear thinning.
- Another class of substances are the modified polysaccharides, in particular cellulose ethers such as carboxymethylcellulose, 2-hydroxyethylcellulose, carboxymethyl-2-hydroxyethylcellulose, methylcellulose, 2-hydroxyethylmethylcellulose, 2-hydroxyethylethylcellulose, 2-hydroxypropylcellulose, 2-hydroxypropylmethylcellulose, 2-hydroxybutylmethylcellulose.
- modified polysaccharides in particular starch derivatives and special polyethers belong to this class of substances.
- the active group of (ii) associative thickeners are, in principle, block copolymers having a water-soluble middle block and hydrophobic end blocks, the end blocks interacting with the particles or themselves, thereby forming a space network incorporating the particles.
- Typical representatives are familiar to the skilled person as HASE (hydrophobically modified alkali-swellable emulsion), HEUR (hydrophobically modified ethylene oxides urethane) or HMHEC (hydrophobically modified hydroxyethyl cellulose).
- HASE hydrophobically modified alkali-swellable emulsion
- HEUR hydrophobically modified ethylene oxides urethane
- HMHEC hydrophobically modified hydroxyethyl cellulose
- the associative thickeners cause more or less Newtonian (shear rate independent) or pseudoplastic (shear fluidizing) flow behavior. Sometimes they also show a thixotropic character, that is, they show not only a shear force dependence of the viscosity but also a time dependence.
- the inorganic thickeners are mostly phyllosilicates of natural or synthetic origin, examples are hectorites and smectites. In contact with water, the individual layers separate from each other. Through different charges on surfaces and edges of the platelets, they form a space-filling house structure in peace, resulting in high quiescent viscosities up to yield points. When shearing collapses the house structure and there is a significant drop in shear viscosity observed. Depending on the charge, concentration and geometric dimensions of the platelets, the structural structure may take some time, so thixotropy can also be achieved with such inorganic thickeners.
- thickeners can be stirred directly into the adhesive dispersion or, in some cases, advantageously prediluted or predispersed in water.
