Definitions

  • the invention relates to a sealing band with a body made of a resilient flexible foam, which is impregnated at least over a cross-sectional area with at least one impregnating agent, and wherein the sealing tape upper and lower broad sides, which can be applied to the opposite joint edges of a sealed building gap, the body of the Dichtbandbreitrise assigned upper and lower broad sides and these connecting narrow sides, which are arranged in Abdichtantechnisch the sealing tape interior space and space outside, and on the lower carcass broadside a self-adhesive layer for attaching the sealing strip is attached to a component, wherein the sealing tape as a roll with a plurality of radially superimposed lying turns is made up and in the turns each of the lower broad side of the body comes with the upper body width for surface contact. Furthermore, the invention relates to a building with the arranged in a joint sealing tape.
  • Sealing tapes which are partially or completely impregnated for delayed recovery, are from the EP 1 600 571 A1 such as EP 688,382 A1 already known. These sealing tapes may have mounting aids such as adhesive tapes for attachment to contact surfaces.
  • sealing tapes can be assembled, stored and transported in the simplest and space-saving manner in the compressed and rolled-up state.
  • the sealing tape properties should as far as possible not change even after long storage, wherein the maximum possible duration of storage is often limited by a deterioration of adhesives contained, for example as a result of separation, exudation or aging thereof, in particular if the adhesives are present in a tack-activated state on the stocked sealing tape ,
  • sealing tape should be produced with little effort and cost.
  • This object is achieved by the provision of a generic sealing tape, in which a cover layer is permanently adhered to the upper broad side of the body, that the sealing tape with the cover layer of a first turn on the self-adhesive layer of an adjacent turn is rolled up and that the adhesive force of the cover layer against the body is greater than the adhesive force of the cover layer against the self-adhesive.
  • the object is achieved by a construction with a sealing tape arranged in a joint according to the invention, wherein the sealing tape with the self-adhesive layer is fastened to a component bounding the joint.

  • the adhesive force of the cover layer with respect to the impregnated body can be higher than the adhesion of the cover layer to the non-impregnated body, which is achieved in particular by the use of hot melt adhesives as an adhesive, in particular in combination with the use of Impregnating agents based on acrylate and / or methacrylate polymers, in which the said polymers are preferably used as a dispersion of the polymer particles, especially preferred as aqueous dispersions.
  • the adhesive force of the cover layer against the body is in this case higher than the adhesive force of the cover layer against the self-adhesive, which may be given, for example, by a suitable choice of the cover layer material and the roughness of the cover layer surface. These requirements are generally met by plastic films.
  • the self-adhesive layer can thus come into contact with the covering layer layer of the underlying turn.
  • the sealing tape according to the invention thus the removal of the cover of the adhesive to expose the self-adhesive surface on the carcass broadside as mounting aid is already done when rolling the sealing tape in one operation. An additional cover layer of the self-adhesive layer to be removed by the customer is thereby unnecessary, so that waste which is produced and disposed of on-site is avoided.
  • the self-adhesive on the impregnated body has a higher adhesive force than on the corresponding body without impregnation.
  • this offers advantages in relation to the sealing strip which is made up as a roll.
  • this increases the maximum storage life of the sealing strip, which ensures that the cover layer can be more easily separated from the self-adhesive without the latter detaching itself from the upper side of the sealing strip, since with increasing aging of the prefabricated sealing strip also a change in adhesive forces the individual layers can enter each other.
  • the adhesive force of the self-adhesive layer against the sealing band body has as For example, also due to a diffusion of components of the self-adhesive in the body and / or a diffusion of components of the impregnating agent in the self-adhesive layer ,
  • the sealing tape according to the invention thus also has an increased storage life.
  • the top layer of the opposite body broad side which rests flat on the free adhesive side of the self-adhesive layer in rolled-up sealing tape can be varied and varied, since when unrolling the sealing tape and separating the self-adhesive layer from the top layer If necessary, even greater adhesive forces between the cover layer and self-adhesive layer are acceptable, as in the case of a non-impregnated body and thus a lower adhesive force between the self-adhesive layer and the cover layer.
  • any change or decrease in the adhesive properties of the self-adhesive layer may occur, for example with regard to adhesion to the body.
  • the cover layer or its surface properties can thus be chosen to be more variable than unimpregnated body and thus low adhesive force of the self-adhesive layer against the cover layer. For example.
  • topsheet may thereby further consist of materials from a wider range.
  • the sealing tape can also be used if in conventional sealing tapes to improve the determination of the sealing strip in the joint itself would be desirable on the opposite Dichtbandbreitseite another adhesive, such as for better attachment of the sealing strip a wall reveal, since sufficient adhesion of the sealing strip is already achieved by the said self-adhesive layer on the component limiting the joint.

  • a cover layer is permanently attached to the body by means of an adhesive layer in the form of a melt adhesive layer on the body upper side 3a.
  • the cover layer is not destructively removable from the body, usually with destruction or damage to the body by adhering to the adhesive layer areas of the body.
  • the melting temperature the adhesive is about 90 ° C.
  • the hotmelt adhesive here is, for example, one based on a thermoplastic PE-EVA copolymer. According to a modification, the hot-melt adhesive (hotmelt) is based on ethylene-vinyl acetate copolymers (EVAC, EVA).
  • the hot melt adhesive may also be applied to the body in multiple layers.
  • the cover layer permanently fixed to the body by means of the hot-melt adhesive is here a plastic film, for example a PE film.
  • the thickness of the cover layer is here about 35 microns thick.
  • the cover layer has a non-stick coating on its free upper side, for example in the form of a very thin silicone layer.
  • a commercially available double-sided adhesive tape is applied as a self-adhesive layer with adhesive-reactive lower side 7a or adhered to the body.
  • adhesive layers are, for example, already used as self-adhesive layers in the sealing tape illmod 600, a product of Tremco illbruck philosophy GmbH, Bodenwschreib, Germany, or in other known sealing tapes.
  • the self-adhesive layer may be factory provided on its side facing away from the body with a decal such as, for example, from silicone paper.

  • This decal is removed before the sealing tape is made up as a roll.
  • the sealing tape with the self-adhesive layer protective, adhered to this decal can be compressed, for example. By passing through a roller mill. Then the decal is removed at the factory.
  • the then free self-adhesive layer is then releasably adhered to the free upper side of the cover layer 6 when rolling up the sealing tape in order to assemble this as a roll.
  • the sealing tape roll can then be handled by the customer in the usual way, with separation of the self-adhesive layer 7 of the cover layer, whereby the free adhesive-reactive bottom 7a of the self-adhesive layer. 7 then exposed.
  • the cut-to-length sealing tape can then be fastened directly to a component such as a frame component.
  • the soft foam material of the body and the impregnating agent (if present) in the above examples a) to e) is the same in each case.
  • the foam material of the body (raw foam) in this case has a density of 28 kg / m3 and an air permeability of 150 l / m 2 s.
  • the self-adhesive layer adheres more strongly to the impregnated foam by about 125 times ((5.0 N / 25 mm) :( 0.04 N / 25 mm)) than on the top layer.
  • adhesion of the self-adhesive layer (double-sided adhesive tape) to the non-impregnated foam is only about 80 times greater than that on the cover layer.
  • impregnated foam is even better than non-impregnated foam Foam ensures that a simple separation of the thin cover layer is made by the double-sided adhesive tape. In this way, the cover layer can be varied more varied, for example.
  • this increases the possible storage life of the sealing strip, for example, from the viewpoint of a reduction in the adhesive force of the cover layer and / or the self-adhesive layer on the body with increasing storage life.
  • top layer with hot melt adhesive adheres more strongly to the impregnated body than on the non-impregnated body, here with about 28% higher adhesion.
  • the sealing tape according to the invention is further characterized in that it has a long service life even at elevated temperature (for example 50 ° C.) and elevated pressure (for example when compressed to 7% of its volume at full free return) in the installation position. It is under these conditions, as they can easily result in temperature-related component displacements in the joint area, virtually no flow of the impregnating film observed, for example, by accumulation of impregnating agent on the non-pressure-loaded sealing strip surfaces can be noticeable.
  • sealing tapes according to the invention can be simulated, for example, by appropriate tests in a drying oven, wherein in the case of sealing tapes according to the invention, even after 1-2 hours or even after 5-10 hours or beyond, for example after 24 or 48 hours, no change or no bleeding can be observed, wherein sealing strips produced by impregnation with acrylate solutions show a significantly more unstable behavior than those produced by impregnation with acrylate dispersions.
  • the sealing strip according to the invention has a very high storage life, without significant change in the adhesive forces of the individual layer we cover layer and self-adhesive layer with the impregnated body and each other.
  • the sealing band body has an air permeability of about 75 l / m 2 s
