Definitions

  • the invention relates to a stretchable sealing tape with a closed surface and at least one underside adhesive layer, wherein the surface consists of a metal foil.
  • Such sealing tapes can be molded on structured surfaces and are used for sealing and packaging purposes.
  • sealing tapes are generally about 0.8 to 1.5 mm thick, wherein the thickness of the metal foil is 0.030 to 0.150 mm.
  • the films generally have a smooth or dimpled surface and allow only very small strains. In many cases, however, a greater Dehn Anlagenkeit would be desirable to bridge protrusions or bumps.
  • Out DE 102 30 552 A1 is a stretchable web material known.
  • a thin metal foil is coated with a tear-resistant non-woven or fabric and then provided by creping transversely to the intended direction of stretching with small wrinkles.
  • This also creates a rugged surface that makes it difficult to glue multiple webs and due to the capillary action makes special measures in sealing required.
  • the creping process requires more material than would be at least necessary for the intended stretch, since a certain excess must be present because of the irregular surface formation.
  • Creped aluminum foils allow high elongation at low tensile forces, which in addition to the good deformability but also has the disadvantage that a so-called micro-fold of about 0.1 mm to 1-2 mm, that can be stretched to 10 or 20 times. Such extreme local strains can not be uniform to the neighboring ones Layers are transferred, but it can cause delamination or cracks under the film, which lead to undesirable capillary effects.
  • sealing tape which consists of an approximately 0.2 mm thick painted aluminum sheet, which has about 3 mm deep shafts transverse to the direction of stretching at a distance of about 6 mm.
  • the corrugated sheet has on the bottom in addition a smooth continuous adhesive layer of butyl rubber of about 1 mm thickness and a release film. It is obvious that the troughs formed by the 3 mm high and 6 mm long waves can not be sealed by a 1 mm thick butyl layer in the case of overlaps, even with careful laying of the sealing tape.
  • the object of the present invention is to provide an expandable sealing strip which has a closed metal surface and, even with overlaps, ensures a tight connection, thus enabling simple assembly and thus minimizing the risk of damage.
  • the basic idea of the invention is to use a closed metal foil and to avoid high local strains by the film being so finely corrugated that the underlying adhesive layer is substantially thicker than the wave height of the foil. This is achieved by the metal foil as in a "fine wave" in the Corrugated cardboard production is curled and the surface makes a nearly closed impression.
  • an aluminum foil of approximately 0.050 thickness is preferably provided with shafts approximately 0.4 mm high and approximately 1.2 mm long.
  • This sealing strips can be made with a total of less than 1.0 mm thickness, which are easy to stretch by hand and can be tightly connected in the overlap area by lightly pressing.
  • the aluminum foil may be coated with a colored acrylate layer or similar varnish for color matching or weathering resistance.
  • the adhesive layer on the underside is preferably a rubber adhesive, but acrylic adhesives, hot melt adhesives, bitumen or special reactive adhesive systems may also be used. It is also conceivable that the troughs with a cheap material such. To fill a highly filled hot melt adhesive and a thin adhesive film, possibly even at the edges, underneath to install.
  • the hot melt adhesive also has the advantage that it can be glued on site with hot air.
  • the cover layer In order to increase the tear strength of a thin metal foil for the cover layer, which would otherwise fulfill all the functions, it can also be reinforced with a plastic film, a plastic non-woven or other organic fibers.
  • the cover layer can also be made of a non-metallic, if necessary vapor-deposited film, such as e.g. a polyester or acrylate film, if it is matched to the restoring forces of the adhesive layer.
  • molded parts such as e.g. Aprons for roof windows are made.
  • Fig. 1 a longitudinal section through the sealing tape according to the invention in a much enlarged view
  • Fig. 2 shows the longitudinal section of the same sealing tape in the stretched state
  • Fig. 3 shows the sealing tape after Fig. 1 with a nonwoven reinforcement of the cover layer and an additional adhesive layer on the underside including a peelable protective film.
  • the sealing tape 1 according to the invention is shown in enlarged longitudinal section.
  • the sealing tape 1 according to the invention has a stretchable cover layer 2 and a lower adhesive layer 3.
  • the stretchable cover layer 2 is a corrugated foil preferably made of 0.050 mm thick aluminum with a wave height h of about 0.4 mm. It can also be color-coated.
  • the lower cover layer 3 consists of butyl rubber.
  • the total height H of the sealing tape 1 according to the invention is 0.9 mm.
  • Fig. 2 shows the sealing band 1 " in a state stretched by about 35% in the shaft direction X.
  • the total height H" is reduced by about 30%, contrary to the elongation, to about 0.7 mm.
  • the stretchable support element 2 is only weakly wavy and the wave height h" is about 0.20 mm, so that just with strong strains of the sealing strip 1 "the bonding with a second sealing strip 1" is facilitated.
  • Fig. 3 shows the sealing tape 1 of the invention Fig. 1 ,
  • the stretchable cover layer 3 is reinforced on the underside of a tear-resistant PE film 5 of 15 g / m 2 basis weight.
  • the adhesive layer 3 is completely or partially coated with a peelable protective film 4 and another thin adhesive film 6.
