Definitions

  • the present invention relates to a roll of sealing tape made of a sealing tape made of soft, compressible foam, which is impregnated for delayed recovery after compression and, at least in some areas, comprises a substance that reduces the thermal conductivity of the sealing tape.
  • Compressible sealing tapes are used to seal joints between a frame profile, e.g. a window or door, and a building wall to seal the joints against drafts and driving rain. Such sealing tapes are usually wound up in a compressed manner to form sealing tape rolls for space-saving storage, for transport and for better handling during assembly. If such pre-compressed sealing tapes are installed in a joint between e.g. In addition to air permeability and driving rain tightness, the thermal conductivity of the sealing tape is one of the most important properties of the sealing tape. A low thermal conductivity of the sealing tape increases thermal insulation.
  • the foams used for the production of sealing tapes have a relatively low thermal conductivity due to the numerous air-filled pore spaces between the cell webs, which means that they are fundamentally suitable for effective thermal insulation.
  • the foam of a compressible sealing tape is usually additionally impregnated with a sticky impregnate in order to delay the return of the compressed sealing tape to its fully expanded state for better workability on the building site. Delayed recovery is often exploited in joint sealing by first compressing the foam into the joint to be sealed, whereupon the foam self-expands to a partially expanded functional state and seals the joint.
  • the impregnation of the foam has the undesirable effect that the thermal conductivity of the sealing tape is increased due to the material properties of the impregnate and its homogeneous distribution within the foam.
  • a joint sealed with such an impregnated sealing tape accordingly has reduced thermal insulation.
  • the WO 2018/127381 A1 discloses a sealing tape that has been treated with an impregnating composition containing airgel particles of fumed silica.
  • the introduced airgel particles are intended to counteract a reduction in the pore spaces present within the foam due to compression of the sealing tape and thus reduce the thermal conductivity of the sealing tape, particularly in a compressed state.
  • the object of the present invention is to provide a sealing tape wound up into a roll of sealing tape, which combines the properties of delayed recovery and high thermal insulation with good compressibility.
  • a sealing tape roll according to the invention consists of a sealing tape made of soft, compressible foam, which is impregnated to delay recovery after compression and at least in some areas includes at least one substance that reduces the thermal conductivity of the sealing tape.
  • the sealing strip has an upper side, a lower side and two side flanks connecting the upper side and the lower side, a longitudinal direction which is aligned parallel to the lower side and to the side flanks and transverse to a transverse direction, and a vertical direction which is aligned perpendicular to the lower side of the sealing strip. on.
  • the sealing tape is wound around an axis, which extends transversely to the longitudinal direction of the sealing tape, to form the sealing tape roll in such a way that the top of a turn rests against the bottom of an adjacent turn of the sealing tape roll and the side flanks of the sealing tape form end faces of the sealing tape roll.
  • the substance is selected from the group consisting of small plastic spheres consisting of a polymeric shell containing gas and expanded due to heating, or graphite.
  • a sealing tape wound onto a roll of sealing tape with delayed recovery wherein the at least one substance increases the thermal conductivity of the Sealing tape effectively reduced, the compressibility of the sealing tape is still given to a large extent.
  • Sealing tapes extend much further in their longitudinal direction than in their transverse direction and are therefore wound up around an axis of rotation to form a sealing tape roll for space-saving storage, during which the foam of the sealing tape is strongly compressed. Even when installed in a partially compressed state, the sealing tape foam does not expand completely, as effective sealing of joints cannot be guaranteed in this way.
  • the installed condition of the sealing tape is defined as the partially compressed condition in which the sealing tape is in a joint between a frame member, e.g. B. a window or door frame, and a building wall is arranged.
  • the longitudinal direction of the sealing tape extends along the circumferential joint and the sealing tape lies flat with the underside and the top on the frame element and on the building wall. One side edge of the sealing strip then faces the inside of the room and the opposite side edge faces the outside of the room.
  • the height direction of the sealing tape extends perpendicularly to the underside between the frame member and the building wall.
  • a high level of compressibility is therefore an essential basis for the versatile and flexible use of a sealing tape.
  • the sealing tape may be compressed to a height in the height direction of 5-25%, for example 10%, 15% or 20% of the initial height of the fully expanded sealing tape.
  • the sealing tape when wound up has a compressed height in the height direction of 5-20%, most preferably 5-15% of the initial height of the fully expanded sealing tape.
  • the sealing tape consists of a permanently elastic soft foam.
  • the foam has a net-like basic structure in which webs with interposed cell membranes are arranged.
  • a foam suitable for the invention is also resilient, ie it should automatically expand back into the uncompressed initial state after compression has taken place.
  • the sealing tape consequently consists of any open-cell or mixed-cell resilient foam selected from the group consisting of polyurethane foam, melamine resin foam, silicone foam, PVC foam or polyethylene foam.
  • the foam is a Polyurethane foam (PU foam).
  • the foam is preferably an open-cell foam, for example an open-cell PU foam.
  • the foam can also be a mixed-cell foam that has both open and closed cell walls.
  • the foam can also be a reticulated foam (eg a reticulated PU foam) in which all or at least some of the foam cell walls have been perforated in the course of an aftertreatment.
  • Such raw foams have a density of 20-200 kg/m 3 , preferably 20-50 kg/m 3 , particularly preferably 28-30 kg/m 3 .
  • the flexible foam preferably has a compressive strength of more than 2 kPa in the raw state.
  • the compression hardness is preferably more than 2.1 kPa, more preferably more than 2.2 kPa, particularly preferably more than 2.3 kPa.
  • the compression hardness is preferably less than 4 kPa, preferably less than 3.8 kPa and more preferably less than 3.6 kPa.
  • the compression hardness is a measure of the strength of the foam. The values given here are based on a compression of 40% compared to the initial height.
  • the compression hardness is determined according to DIN EN ISO 3386 and the CV40 is specified.
  • the foam forming the sealing tape is also at least partially and preferably completely treated with a sticky impregnate to delay the recovery of the compressed foam after its compression and thus provide sufficient time for sealing even difficult-to-access or particularly thin joints.
  • the impregnate is preferably a sticky solution, suspension or dispersion. It preferably has an acrylate dispersion. In an advantageous embodiment, the acrylate dispersion has acrylate polymer particles dispersed in a homogeneous phase.
  • the foam is particularly preferably impregnated with a proportion by weight of acrylate dispersion for delayed recovery in such a way that the sealing tape at 20° C.
  • the impregnate also contains at least one substance that reduces the thermal conductivity of the sealing tape.
  • the terms “reduce”, “reduce” or “reduce” the thermal conductivity are to be understood in this way be that the thermal conductivity of a sealing tape due to the at least one substance is lower than that of an otherwise identical sealing tape that does not contain this substance.
  • the substance is present in the impregnate in a proportion of 1-25% by weight, preferably 1-7% by weight, more preferably 3-6% by weight, most preferably 5-6% by weight, respectively based on 100 wt .-% impregnate before.
  • the substance does not dissolve in the impregnate, but remains in particle form.
  • the substance is preferably distributed homogeneously in the impregnate, i.e. the substance is preferably dispersed in the impregnate.
  • the impregnate can also contain one or more binders, fillers and/or auxiliaries, e.g.
  • the impregnate can give the foam and, accordingly, the sealing tape additional functionalities, such as flame retardancy, UV protection, hydrophobicity, airtightness or coloring, in addition to delayed resilience and reduced thermal conductivity.
  • the sealing tape preferably meets a number of DIN standards with regard to e.g. Resistance.
  • the foam of the sealing tape is impregnated with the impregnate comprising the substance by means of impregnation.
  • the foam is immersed in the impregnate in such a way that the impregnate penetrates into the foam cells together with the substance and completely or at least partially wets the inner and outer cell structure. Therefore, the impregnate used for the impregnation of the sealing tape should preferably be of average viscosity.
  • the sealing tape comprises an open-cell foam in order to achieve the most homogeneous possible penetration and distribution of the impregnate and thus of the substance in the foam. The amount of impregnate absorbed by the foam can then optionally be adjusted by squeezing or squeezing out the impregnated foam.
  • a foam impregnated in this way has a density of 30-150 kg/m 3 , preferably 50-70 kg/m 2 , for example 55 kg/m 2 , 60 kg/m 2 or 65 kg/m 2 .
  • the substance that reduces the thermal conductivity is introduced into the sealing tape. Accordingly, the substance is not added to the starting materials during the production of the foam, but is subsequently added to the raw foam that has already been produced. This allows the sealing tape to be flexibly equipped with the at least one substance.
  • the substance is distributed homogeneously in the sealing strip as a result of the impregnation, i.e. the substance is distributed in a largely uniform manner over the entire width and the entire length of the sealing strip.
  • the substance is in the final sealing tape of the sealing tape roll in a proportion of 0.2-15% by weight, preferably 0.3-10% by weight, e.g. 0.3% by weight, 1% by weight or 3% by weight.
  • the sealing tape can also be divided into different sub-areas, which are separated from one another, for example by means of suitable separating layers present in the foam, and the substance is only in one or more, but not in all, sub-areas of the sealing tape.
  • a sealing tape can be provided in which different partial areas have different functionalities.
  • the substance can also be present in different concentrations in the various sub-areas.
  • it can also be advantageous to gradually increase or reduce the concentration of the substance along the length of the sealing tape by selectively squeezing the impregnate out of the foam. As a result, different sections of the sealing tape can have different density.
  • the substance should also be dimensioned in such a way that it is present in the cells of the foam after impregnation.
  • the substance should therefore consist of individual particles whose diameter is less than 500 ⁇ m, preferably less than 400 ⁇ m, less than 300 ⁇ m, less than 200 ⁇ m and most preferably less than 150 ⁇ m.
  • the substance preferably consists of microspheres, ie small plastic spheres, which consist of a polymer shell containing gas and are expanded due to heating, the plastic spheres in the expanded state having a diameter of 30-120 ⁇ m, preferably 30-50 ⁇ m, e.g 35 ⁇ m, 40 ⁇ m or 45 ⁇ m.
  • the surfaces of the plastic balls can be modified, eg have a hydrophobic surface layer.
  • the plastic beads are preferably added to the impregnate in an unexpanded state with a diameter of about 10 ⁇ m, ie they are dispersed in the impregnate.
  • the balls then expand due to the temperature increase during drying of the impregnated foam.
  • the impregnated foam is usually dried at temperatures of 70° C. to 210° C., preferably at about 100° C. to 190° C., for a period of about 1 to 20 minutes. Due to the heating, the gas inside the plastic balls expands and increases the internal pressure, while the polymer shell softens due to the heat. As a result, the volume of the microsphere increases, usually in excess of forty to sixty times the original volume.
  • the specific weight of the plastic balls is reduced from around 1,000 kg/m 3 to around 30 kg/m 3 .
  • partially or completely pre-expanded plastic beads can also be added to the impregnate. Microspheres, expanded due to heating, retain their increased volume for a long time even under ordinary temperature conditions. At the same time, however, the expanded plastic balls remain permanently elastic, i.e. they can still be compressed within the sealing tape. This means that the sealing tape can be wound onto a roll of sealing tape in a highly pre-compressed state, despite the plastic balls it contains.
  • the spheres form bulbous, gas-filled projections which lead to a reduction in the thermal conductivity of the sealing tape.
  • thermal conductivity also thermal conductivity number ⁇ , k or ⁇ refers to the property of a substance to transport thermal energy in the form of heat by means of thermal conduction, i.e. thermal conductivity is determined by the speed at which heat spreads through a substance. Thermal conductivity is expressed in watts per meter Kelvin (W/mK).
  • the thermal conductivity of the sealing tape comprising the plastic spheres described herein is between 10 and 10 in both a partially compressed state 90%, preferably between 10 and 80%, more preferably between 40 and 75%, and in a non-compressed state ⁇ 0.040 W/mK, preferably ⁇ 0.395 W/mK.
  • the information on thermal conductivity given in this application refers to a determination under the standard conditions according to DIN standard EN 12667 using a plate device provided for this purpose, taking into account the sample dimensions and density at a mean temperature of the sample of 10°C (see example below) .
  • a sealant's thermal conductivity increases as it is compressed as the cell walls of the individual foam cells are compressed. Since the sealing tape must be at least partially compressed when installed in order to completely seal a joint, the thermal conductivity should not be > 0.040 W/mK when the sealing tape is compressed by at least 50%.
  • the thermal conductivity of the sealing tape can possibly be further reduced by varying the volume size of the microspheres and their quantity in the sealing tape. For example, by increasing the volume size of the balls, the thermal conductivity of the sealing tape can be reduced accordingly.
  • the inventors determined that a proportion of the plastic balls in the impregnate of 6% by weight (based on 100% by weight impregnate) noticeably reduced the conductivity of the sealing tape impregnated with them (see example).
  • the proportion of plastic balls in the final sealing tape is therefore preferably 0.2-15% by weight, particularly preferably 0.3-10% by weight, for example 0.3% by weight, 5% by weight or 10% by weight (based in each case on 100% by weight of sealing tape). This proportion ensures reduced thermal conductivity and high compressibility of the sealing tape.
  • the at least one thermal conductivity-reducing substance consists of graphite, preferably graphite in the form of graphite dust consisting of graphite particles with an average particle size of 5-500 nm, preferably 5-200 nm, eg 100 nm Determination of particle sizes known from the prior art.
  • the average particle size of the graphite dust particles can be measured using laser diffractometry or spectroscopic methods.
  • the graphite may also be in the form of larger graphite flakes having an average particle size of 5-500 ⁇ m, preferably 5-200 ⁇ m, more preferably 5-100 ⁇ m, 5-50 ⁇ m, 5-25 ⁇ m, most preferably 5-15 ⁇ m, e.g 10 ⁇ m.
  • the graphite is preferably not present in the form of rigid, ie non-compressible, airgel particles.
  • the graphite preferably the graphite dust
  • the graphite dust is introduced into the foam via the impregnate and is thus distributed homogeneously within the cell structure.
  • the graphite dust is preferably so fine and is arranged in the compressible foam in such a way that the individual graphite dust particles do not or at least hardly touch each other even in the heavily precompressed sealing tape on the sealing tape roll. The effect of this is that the heat conduction between the individual graphite particles is disrupted or, preferably, completely prevented.
  • the graphite evenly distributed in the foam reflects thermal radiation and thereby reduces the heat transport within the sealing tape.
  • the thermal conductivity of the sealing tape which includes the graphite, preferably the graphite powder, is both in a partially compressed state of between 10 and 90%, preferably between 10 and 80%, more preferably between 40 and 75%, of the initial height and in the uncompressed state ⁇ 0.040 W/mK, preferably ⁇ 0.0385 W/mK.
  • the exact extent of the reduction in thermal conductivity caused by the graphite can be controlled, among other things, by the amount of graphite that is added to the impregnate before the foam is impregnated. It can be advantageous if the impregnate contains more than 2% by weight, more than 7% by weight or even more than 10% by weight of graphite, based on 100% by weight of impregnate.
  • the impregnate can contain up to 15% by weight of graphite.
  • a significantly higher proportion of graphite in the impregnate would result in the foam absorbing too much graphite during impregnation, so that the individual graphite particles are mostly in direct contact with one another. This can lead to an undesirable increase in thermal conductivity, which would override the desired principle of thermal radiation reflection.
  • the proportion of graphite in the final sealing tape is preferably 0.1-10% by weight, particularly preferably 0.2-7% by weight, for example 0.2% by weight, 1% by weight or 3% by weight (in each case based on 100% by weight of sealing tape).
  • the final sealing tape has a height of 5 mm-200 mm, preferably 10 mm-120 mm, particularly preferably 10 mm-90 mm or 20-80 mm.

  • the side flanks 8, 10 In the compressed state of the sealing strip 2, the side flanks 8, 10 have a lower height (H1) than in the expanded state of the sealing strip 2 (height H2).
