Definitions

  • the present invention relates to a geometrically defined pressure-sensitive adhesive film that was produced using stereolithography processes.
  • coating units which usually coat the liner over its full width; certain coating geometries (points or strips) are also possible to a narrowly limited extent in such units. In any case, however, it is neither possible to vary the geometries completely freely in a single coating step, nor is it possible to produce different geometries in a single coating step, such as are necessary for gluing emblems consisting of different letters or other symbols.
  • a stamping process is usually used after the coating process. This procedure has the disadvantage of the often low degree of material utilization, since the production of the stamped parts produces up to 90% waste that cannot be used.
  • An adhesive layer produced in this way is preferably used as a carrierless adhesive tape (transfer tape), but can also form an adhesive layer of an adhesive tape.
  • Adhesive layers that are to be used as a pressure-sensitive adhesive tape and are not provided with a stable backing can be brought into a geometrically defined shape only with difficulty, if at all. All previous attempts to accomplish this with the usual current manufacturing processes result in damage to the tape produced or render it unusable.
  • the new manufacturing process of the Polyjet Modeling process according to the invention falls into the category of the processes known as “rapid prototyping” or “additive manufacturing” and is therefore a “3D printing” application in the broadest sense.
  • WO 2019/120818 A1 describes in very general terms the production of an adhesive surface by applying an adhesive to at least one surface of a part to be joined or a transfer adhesive carrier using a 3D printing device.
  • the corresponding 3D printing device which works according to the inkjet principle or is fed by an endless strand, and the method for gluing two parts to be joined are also claimed here.
  • This method is also used for a wide selection of different types of adhesive that can be used here, as well as for both homogeneous and different layer thicknesses.
  • EP 3196000 B1 describes a method for producing a composite material component by printing a component skeleton and introducing a resin into this skeleton.
  • the skeleton can be printed using the PolyJet printing process.
  • WO 2019/1215170 A1 claims an aqueous acrylic adhesive dispersion for 3D printing
  • WO 2020/146452 A1 an additive manufacturing process using an amine-containing adhesive polymer
  • WO 2020/165193 A1 claims a 3D printing process
  • adhesive film or “adhesive film” means any form of two-dimensional adhesive systems, i.e. not only adhesive films, but also adhesive tapes, adhesive foils, adhesive strips, adhesive plates or adhesive die-cut parts.
  • adhesive tape or “adhesive film” also includes so-called “transfer films”, ie unsupported adhesive tapes.
  • Adhesives or adhesive films are referred to as “pressure-sensitive adhesive”, “pressure-sensitively sticky” or “pressure-sensitive” adhesives, which are able to join two joining partners to one another only by applying pressure.
  • pressure-sensitive adhesive pressure-sensitively sticky or “pressure-sensitive” adhesives
  • a permanent connection between the joining partners can be realized under relatively weak contact pressure. The connection is reversible, i.e. it can be released again without destroying the parts to be joined.
  • 3D printing means the application of adhesive masses to a liner using the stereolithography process.
  • Root temperature means a temperature of 23 ⁇ 2 °C.
  • a further object is to provide a geometrically defined pressure-sensitive adhesive film which has been produced in the stereolithography process by means of band polymerisation.
  • a geometrically defined pressure-sensitive adhesive film having the features of claim 1.
  • Advantageous developments result from the dependent claims. Accordingly, a geometrically defined pressure-sensitive adhesive film based on a generative printing process is specified, the pressure-sensitive adhesive composition particularly comprising acrylates.
  • UV acrylates are processed with the stereolithography method and printed in geometrically defined forms.
  • the geometric shape in all spatial directions, so that not only two-dimensional adhesive tapes with a geometric definition, but also three-dimensional adhesive tapes with a geometric definition can be produced.
  • a pressure-sensitive adhesive film has a bond strength of at least 0.2 N/mm.
  • the bond strength is determined here on steel based on DIN EN 1939:1996 at 23° C. ⁇ 2° C. and 50% ⁇ 5% relative humidity at a peel-off speed of 300 mm/min and a peel-off angle of 180°.
  • an etched PET film with a thickness of 50 ⁇ m is used as the intensifying film.
  • a 25 mm wide measuring strip is bonded to the steel substrate using a 5 kg roller at a temperature of 23 °C ⁇ 2 °C.
  • the adhesive film is pulled off at 300 mm/min 10 minutes after application.
  • the measured value (in N/mm) is the mean of five individual measurements.
  • Pressure-sensitive adhesives have a permanently tacky effect at room temperature, ie they have a sufficiently low viscosity and high initial tack, so that they wet the surface of the respective substrate even with slight contact pressure.
  • the bondability of the adhesives is based on their adhesive properties and their redetachability on their cohesive properties.
  • the geometrically defined pressure-sensitive adhesive film has no backing and is therefore suitable for forming a transfer film.
  • the adhesive mass which corresponds to the finished adhesive film in the final state, is applied to a flexible material such as a film or between two flexible materials before application.
  • a flexible material such as a film or between two flexible materials before application.

  • a further storage container with a second adhesive and a further post-crosslinking line are connected behind the first storage container and the post-crosslinking line. It is thus possible to implement an asymmetrical adhesive tape structure with all of the adhesives mentioned below by connecting storage containers in series.
  • One of these printed adhesives can also function as a carrier system, so that all imaginable layer structures are technically possible.
  • Adhesive films or adhesive tapes are also possible in which two liners are not used, but rather only a single liner that is repellent on both sides.
  • a first side of the adhesive film is covered with one side of the double-sided separating liner and a second side of the adhesive film when it is wound onto a roll or a spool is then covered with the reverse side of the double-sided separating liner.
  • the geometrically defined pressure-sensitive adhesive film has at least one backing. If a backing material is present, it can be provided with a geometrically defined (pressure-sensitive) adhesive on one or preferably both sides.
  • the carrier material includes all flat structures such as foils, foams, fabrics, scrims, nonwovens and papers or combinations thereof. Different backings can be combined with the adhesives for different applications. In this embodiment, only the carrier material needs to be finished if necessary, which means that the overall waste is significantly reduced compared to the standard coating and punching process.

  • Layer thicknesses between 100 ⁇ m and 1000 ⁇ m are ideally suited for bridging tolerances in the parts to be bonded.
  • Layer thicknesses between 1 ⁇ m and 50 ⁇ m lead to reduced adhesion on the parts to be joined, but at the same time reduce the amount of material used.
  • Adhesives used are, on the one hand, all adhesives known to those skilled in the art based on UV acrylates, which can be polymerized by means of UVA, UVB or UVC. Examples of such adhesives are well known and described in adhesive practice and in the literature.

  • the adhesive films K1 and R1 have an identical chemical composition. Only the manufacturing process is varied. Thus, R1 is coated using standard coating processes in a 2-roller application over a width of 450 mm and band-polymerized. In contrast to this, K1 is applied in the width to be tested by means of stereolithography processes and is also band-polymerized.
  • the adhesives K1 and R1 have the same bond strength both initially and after 24 hours.
  • K1 has a higher lap shear strength than R1, but experience has shown that this is due to the lower adhesive layer thickness.
  • the tensile shear strengths would therefore also be the same within the scope of the standard deviation if the thickness of the adhesive layer was identical. It can thus be said that the geometrically defined pressure-sensitive adhesive layer which was produced using the stereolithography process has the same technical adhesive properties as a conventionally coated adhesive film.
