Definitions

  • the invention relates to the use of an adhesive tape for gluing in particular rigid foam parts.
  • Japanese laid-open publication JP 07 179 828 describes a single-sided adhesive tape which has a carrier to which a second layer is applied, which contains a metallic structure. A pressure-sensitive adhesive is in turn coated on the second layer. Due to the metallic structure, the second layer can be heated via magnetic induction, which reduces the adhesive strength of the pressure-sensitive adhesive.
  • an adhesive force is only generated in the adhesive coating by heating the metallic layer to a certain temperature. If this temperature is exceeded, the adhesive tape is removed.
  • the tape When used, for example when sealing plastic containers, the tape sticks to the body due to the pressure sensitive adhesive.
  • the adhesive tape can then only be detached from the substrate if the adhesive strength of the pressure-sensitive adhesive is reduced.
  • the heat generated by induction in the metallic structure of the second layer serves to detack the adhesive tape,
  • Two parts to be glued cannot be connected to one another with the disclosed adhesive tape in such a way that separation is only possible by destroying or damaging at least one of the two parts.
  • An adhesive tape which is disclosed in EP 0 237 657, has a comparable structure.
  • the adhesive tape is used to connect pieces of carpet, which are glued together by means of the adhesive tape, by induction to the Generation of sufficient adhesive power is required in the metallic layer.
  • Strapless adhesive tapes made from butyl rubber compositions which stick on both sides are also known.
  • priming is also cost-intensive.
  • the hard foam part can be pressed onto the surface with high pressure, while at the same time both the surface, the adhesive tape and the hard foam part are annealed.
  • the materials to be glued together mainly non-ferrous materials
  • the materials to be glued together can easily be damaged, for example deformed.
  • parts must be pressed with very high pressure in order to achieve sufficient adhesive strength.
  • this entails a high level of mechanical effort.
  • both methods are complex and therefore time-consuming, and in some cases also impractical.
  • the invention is based on the object of providing an adhesive tape with which the quick and secure bonding of, in particular, hard foam parts can be achieved.
  • the invention relates to the use of an adhesive tape for bonding hard foam parts in particular, very particularly those made of polyurethane or polyethylene, the adhesive tape consisting of a metallic intermediate carrier and a thermoplastic adhesive, preferably a self-adhesive butyl rubber adhesive.
  • the adhesive tape is also suitable for fastening open, rough and / or uneven plastic fabrics, webs or webs or similar known materials.
  • the adhesive tape preferably has a thickness of 0.2 to 4 mm, in particular of 1 to 2 mm.
  • the metallic intermediate carrier preferably has a thickness of 10 ⁇ m to 1000 ⁇ m, in particular of 40 ⁇ m to 60 ⁇ m, very particularly 50 ⁇ m.
  • the metallic intermediate carrier preferably consists of an aluminum foil, but in addition to this, the metallic intermediate carrier can consist of a metallic grid and / or a metallic fabric.
  • an adhesive tape can be used for gluing, in particular, rigid foam parts, which consists of a thermoplastic adhesive, a metal powder or metallic fibers being particularly homogeneously distributed in the thermoplastic adhesive.
  • the self-adhesive butyl rubber adhesive consists of a pre-crosslinked butyl rubber which is mixed with carbon black, talc, plasticizers and resin.
  • the self-adhesive butyl rubber adhesive advantageously has a shear strength greater than 5 cN / cm 2 at temperatures of 130 ° C. and undergoes crosslinking after heating to above 130 ° C.
  • the adhesive tape thus has a certain cohesiveness at temperatures below 130 ° C. After heating to temperatures above 130 ° C there is a crosslinking, which is responsible for the fact that the mentioned cohesiveness is exceeded after cooling to room temperature. At the same time, the viscosity of the butyl rubber adhesive is reduced during the heating, so that the porous or rough substrates to be bonded are properly wetted.
  • the method shown below has proven to be particularly advantageous for producing the adhesive tape according to the invention with an aluminum foil. Thereafter, the self-adhesive butyl rubber adhesive, which is covered with release paper, is first applied to both sides of an aluminum foil in a strip-like manner, with at least one strip per side, and then the coated aluminum foil is cut to lengths of the desired dimensions.
  • the adhesive is used optimally, there is no waste.
  • the method with which the hard foam parts are glued to a solid surface also lies within the inventive concept.
  • the process can be described as follows: a) First, adhesive tape sections are glued to the substrate. b) Then the preformed hard foam part is glued onto the adhesive tape sections, whereby the hard foam part is fixed in the desired position. c) During the same time causes an induction machine by induction heating of the metallic intermediate carrier in the adhesive tape on at least 130 ⁇ C to 200 ° C, is pressed, the hard foam part ending with a slight, manually generated pressure on the ground.
  • a hard foam part is to be glued to lacquered surfaces or similarly smooth surfaces, it is also sufficient if the metallic intermediate layer is fixed to the lacquer surface with a usual inexpensive fix, i.e. an adhesive tape that is adhesive on both sides. Due to the excellent, extremely smooth surface of the lacquer layer, the adhesive strength that can be achieved with the fix is sufficient.
  • the rigid foam part on the other hand, must in turn be fixed with a section of the preferred butyl rubber adhesive according to the induction process described.
  • the adhesive tape 3 which consists of three layers 31, 32, 33 composed, glued to the inner door panel 1, and divided into several sections.
  • the first layer 31 and the third layer 33 of the adhesive tape 3 are formed by a butyl rubber compound, in which a second, metallic layer 32 is embedded, consisting of an aluminum foil.
  • the metallic layer 32 is then heated by induction for a total of 2-5 seconds, to a temperature of 200 ° C.
  • the temperature in the surrounding layers 31, 33 made of butyl rubber increases at the same time. This rise in temperature ensures that, on the one hand, the viscosity of the butyl rubber composition becomes lower, that is to say it wets the existing unevenness more intensely, and, on the other hand, an increase in the adhesive force in the adhesive composition.
  • the hard foam part 2 is pressed onto them with a slight manual pressure.
  • FIG. 2 shows the process in the view of the hard foam part 2 (shown here as “transparent”).
  • the two, here square-shaped, adhesive sections 3 which are used to glue the hard foam part 2 onto the inner door panel 1.
  • the adhesive tape produced according to the particularly advantageously described manufacturing process is used for bonding hard foam parts.
  • two strips 31 and 33 of the butyl rubber adhesive are each applied by lamination above and below an aluminum foil 32, which is used as a metallic intermediate carrier, and then the aluminum foil 32, which is then coated on both sides, is cut to length.
  • the section 3 thus produced in the desired length is pressed onto the inner door panel 1. Due to the low self-adhesion, it sticks to it. Only then is the rigid foam part 2 placed on the section 3.
  • the aluminum foil 32 heats up by induction. This heat is passed on to the strips of butyl rubber adhesive 31, 33. The slight manual pressure ensures that the porous or rough surfaces of the hard foam part 2 or the door interior trim 1 are properly wetted.
  • FIG. 4 again shows the type of gluing according to FIG. 3 in view of the rigid foam part 2 (also shown here as “transparent”).
