Definitions

  • the invention relates to a foam sealing tape, which has based on a fully recovered state across its width two height areas connected by a low area, wherein the foam sealing tape is soaked for delayed recovery and in the low region an insert is disposed, wherein the insert formed swelling is.
  • a foam sealing tape is for example from the WO 2009/138311 A1 known.
  • the known foam sealing tapes are used in a compressed state in a joint. According to the impregnation for delayed recovery, these foam-sealing tapes then return over a certain period of time, such that they regardless of their design in the fully recovered condition profiled design having all over the other side, so for example, the soffit of the window opening abut.
  • the sealing tapes are preferably produced from an integral foam strip and, opposite to their contact surface on the reveal, more preferably have a self-adhesive layer, which may initially be covered, as supplied, with a cover layer.
  • the EP 243699 A2 describes a fire seal tape consisting of one or more flexible, highly compressible sealing strips and with one or more Intumeszenz fire protection carriers, wherein the fire protection or the or are completely or largely covered by the sealing strips.
  • the insert preferably consists at least partially of a material other than foam, in particular of a foam other than the mentioned open-cell, for the delayed return.
  • a material other than foam in particular of a foam other than the mentioned open-cell, for the delayed return.
  • it can also consist of such an open-cell, soaked for delayed recovery foam, in which case, preferably in particular in the impregnate, function-improving additives are included.
  • the subject of the invention thus relates to the foam-sealing tape according to claim 1 as such, based on a fully recovered state over its width has two height ranges connected by a low region, wherein the foam-sealing tape is soaked for delayed recovery and in the low region an insert is arranged, and according to the further subclaims.
  • the insert is made of a swellable material. In this case, reference is made in full to the materials described below.
  • the foam sealing tape can be adapted to different requirements by the insert, regardless of the foam, for example, in terms of waterproofness, fire protection behavior, without interference with the foam material, as would be the case for example with an impregnation of the foam material with a particle-containing impregnate , Nevertheless, the property profile of the sealing strip as a whole and, for example, in the case of a change in volume of the insert in the case of a changing environment such as exposure to moisture or, in the case of fire, also the properties such as, for example, the air permeability of the foam material can be changed.
  • the foam is, for example, a polyurethane foam.
  • the open cell nature can be characterized by an air permeability.
  • the air permeability can be, for example, in the range from 20 to 1000 l / m 2 sec, measured according to DIN EN 9237 on a 10 mm thick sample at 0.5 mbar vacuum, sample surface 100 cm 2 , for example in the range of 20 to 500 l / m 2 sec or 20 to 250 l / m 2 sec, for certain applications preferably 20 to 150 l / m 2 sec or 50-200 l / m 2 sec at the desired low air permeability.
  • the measurement can be performed with a Frank device, for example the Frank device type 21443.
  • the foam may have a density of, for example, 25 to 100 kg / m 3 .
  • the insert consists of a source material.
  • a source material This is a material swelling with respect to moisture and also a material which swells with respect to heat, as is known in particular as an intumescent material, but according to the invention a combination of the two materials.
  • a swelling material for example, the seal in the building can be improved.
  • the passage of water can be delayed and / or the air permeability of the foam sealing tape by the swelling, which then - in the installed state - a higher compression in the joint is reduced.
  • a kind of dynamic sealing can also be established so that, depending on the moisture content of the environment, a higher or lower sealing force acts on the soffit or the inserted part, such as the window frame.
  • the moisture-swelling material is thus preferably reversibly swellable, so in dry air again before under swelling recorded water, for example at 25 ° C and 5% relative humidity.
  • the intumescent compound can provide a seal against air leakage and a fire resistance in case of fire.
  • the swellable (moisture-swellable) mineral is particularly preferably a clay mineral, in particular bentonite. Such is easily introduced into the insert and particularly environmentally friendly and harmless even in case of fire, since unlike organic materials no fire gases are released.
