Abstract

Multilayer composite seal (2a-c) formed from at least one moisture-impermeable and / or vapor-barrier separating layer (4) made of aluminum, and at least one fabric layer (6) connected to the separating layer (4), wherein the composite seal (2a-c) preferably has no bitumen ,

Description

The invention relates to a multilayer composite seal to seal against moisture and vapor.

In construction, the seal plays against moisture, such. As against non-pressing water, an important role. To protect walls, floors and roofs from damaging water absorption are used as moisture barrier water-repellent protective coatings, mineral waterproofing or impregnation such as plastic dispersions, the z. B. applied to an outer surface of a basement wall. Alternatively, PVC films or bitumen membranes are arranged as so-called wall barriers in or under a wall.

It is an object of the invention to provide an improved composite seal for sealing against ingress of moisture and steam or water in buildings.

This object is achieved with the features of claim 1, 26 and 29, respectively.

Advantageous embodiments are the subject of the dependent claims.

According to claim 1, a multi-layer composite seal or structural seal is provided, the z. B. as a wall barrier (on, in or under a wall), as a screed barrier (eg., On a raw concrete ceiling under a screed, eg., Before applying the thermal insulation and a release liner), as a roof barrier or flat roof z. B. on a trapezoidal roof or concrete roof and as a moisture barrier (eg., For a basement or in wet areas), in particular as a vapor barrier can be used.

The multilayer composite seal consists of at least one moisture-impermeable and / or vapor-barrier separating layer of aluminum and at least one fabric layer connected to the separating layer. The composite seal preferably has no bitumen. Unlike the prior art, in the present composite seal, the aluminum barrier provides the moisture barrier / vapor barrier so that the use of bitumen is not necessary. Due to the aluminum separating layer, the composite seal has an S _d value> 1500 m. The use of aluminum (rather than aluminum bituminous sheets), especially aluminum in combination with acrylate or hot melt adhesives, significantly reduces the basis weight of the composite seal, thereby facilitating handling. Furthermore, in contrast to bitumen membranes or aluminum bituminous membranes, aluminum is much less sensitive to temperature and remains flexible even at temperatures of up to minus 5 ° C., ie the composite sealing can be well processed even at low temperatures.

The fabric layer or a fabric is a crossed (eg right-angled or nearly rectangular) thread system of longitudinal threads (warp threads) and transverse threads (weft threads), in which the threads pass in a certain rhythm (binding) above and below the transverse threads. The binding of the fabric or the "weave" of the threads with each other creates a strong and dense composite, which ensures high tear resistance and tear strength of the composite seal. When installing the composite seal, therefore, mechanical damage of the composite seal can be prevented, so that a tight barrier against water and water vapor is ensured even under load during or after installation. Preferably, the fabric layer is formed of a natural fiber, glass fiber or plastic fiber (eg polyester, or polyethylene (PE)).

The at least one fabric layer may have a thread density in the longitudinal direction and / or transverse direction between 3-15 threads / cm, preferably between 5-10 threads / cm, more preferably between 3 to 7 threads / cm, and additionally or alternatively a grid spacing in at least one (Lattice) direction of not more than 5 mm, preferably not more than 4 mm and more preferably not more than 2 mm. The specifications for thread density and grid spacing relate to a mean thread density and an average grid spacing in which a manufacturing tolerance must be taken into account. The at least one fabric layer preferably forms a closed or substantially closed surface or closed surface image.

Preferably, the at least one fabric layer has a basis weight of preferably 20 g / m ² -150 g / m ² , preferably 50 g / m ² -120 g / m ² and particularly preferably 60 g / m ² -90 g / m ² . For example, the fabric layer has a basis weight of about 70 g / m ² .

Preferably, the composite seal has at least a first protective layer, which is connected to the separating layer, and optionally at least a second protective layer, which is connected to the fabric layer. The separating layer and fabric layer are therefore preferably coated on both (outer) sides with a protective layer or protective layer. The first protective layer and / or the second protective layer are alkali-resistant, so that the two protective layers protect the non-alkali-resistant aluminum from damage.

The individual contiguous layers of the composite seal may be interconnected in various ways. Bonding, laminating, spraying, fusing, concatenating and melt pressing are particularly advantageous. In this case, different methods can be used to connect the individual layers together. Particularly preferably, the second protective layer is connected to the fabric layer by means of fusing and / or gluing, the fabric structure of the fabric layer penetrating through the protective layer or forming on the outside of the protective layer, so that mortar can anchor itself to the fabric structure. or better adheres to the composite seal.

The aluminum separating layer preferably has a thickness of 9 μm-20 μm, preferably 10 μm-15 μm and particularly preferably 10 μm-13 μm. For example, a thickness of about 12 microns.

The first protective layer is preferably made of plastic, in particular of polyethylene terephthalate (PET) or of a PET film or of high-density polyethylene (HDPE). The density of HDPE is between 0.94 g / cm ³ to 0.97 g / cm ³ . In particular, the first protective layer may have a thickness of preferably 10 μm-50 μm, preferably 15 μm-30 μm and particularly preferably 20 μm-25 μm. For example, a first protective layer of PET has a thickness of 23 μm. The use of PET offers the further advantage that the density of the composite seal against moisture / steam is increased. In particular, when using a protective layer made of PET with a larger surface density or a thicker / thicker protective layer, the areal density (thickness) of the aluminum separating layer can be reduced without the S _d value of the composite seal being reduced.

Preferably, the second protective layer is made of plastic, in particular of low-density polyethylene (LDPE). The density of LDPE is between 0.915 g / cm ³ and 0.935 g / cm ³ . The second protective layer may have a basis weight of preferably 10 g / m ² -50 g / m ² , preferably 15 g / m ² -40 g / m ² and particularly preferably 20 g / m ² -30 g / m ² . For example, a second protective layer of LDPE has a basis weight of 25 g / m ² . Particularly preferred as the second protective layer, a flame retardant (FR = flame retardant) LDPE coating is used, for. B. with an areal density of 25 g / m ² .

By using the materials described above, the composite seal is much less sensitive to temperature than bitumen or PVC and remains flexible even at temperatures as low as -20 ° C to -40 ° C, allowing the composite seal to work well even at low temperatures can. For example, a folding of the composite seal up to a temperature of -20 ° C is possible, for. B. for making a so-called L-lock or Z-lock. Usually, when using less flexible masonry barriers such. B. PVC when forming a Z or L-lock at the transition between the horizontally extending ground and the vertical wall formed a groove to avoid a sharp kink in the PVC web at this transition or to prevent the rigid PVC web breaks at this point. In contrast, the above-described highly flexible composite seal can easily be bent at a (sharp) angle of 90 °, so that when used as an L or Z-lock, the formation of a groove at the transition between the horizontally extending ground and the vertical wall is not necessary.

In addition, the flexibility of the composite seal makes it easy to form connections to existing sealing levels or to masonry. For example, the composite seal described above (as opposed to the relatively stiff bitumen or PVC) can simply be bonded flat to a wall / wall because the flexible composite seal adapts to any surface. In particular, the composite seal is compatible with bitumen and PVC and can be bonded or glued without problems to these materials.

Preferably, the composite seal is web-shaped, so that it can be easily transported and processed as a roll product. For example, the composite seal may be provided as roll stock having a width of between 0.1m-1.5m. Preferred web widths are: 11.5 cm, 17.5 cm, 24.0 cm, 30 cm, 36.5 cm, 50 cm, 75 cm and 100 cm. Due to the low surface density of the multi-layer composite waterproofing, significantly more running meters per meter of roll can be provided without impairing the handling properties (during laying). For example, a PVC masonry barrier typically provides 25 meters per roll. For example, a multi-layered composite seal as described above may be provided at 50 meters per roll, i. H. The compound seal can be laid in greater length without any Anstückeln, so fewer connections (between the individual roles) are necessary. Fewer connections mean less assembly work and less potential weaknesses in the sealing layer of the composite seal.

For connecting individual web-shaped composite seals (in the longitudinal direction), a first adhesive strip may be arranged in a first end region on a first side of the composite seal and optionally in an opposite second End region may be disposed on an opposite second side of the composite seal a second adhesive strip. Ie. in the optional embodiment, an adhesive strip is disposed on an upper surface at one end of the sealing sheet and a second adhesive strip is disposed on a lower surface at the other end of the sealing sheet. When two webs are joined, the ends or end regions of the webs to be joined are arranged in an overlapping manner so that the adhesive strips rest on one another at the end regions of the webs. This provides a 'glue-on-glue' compound, which immediately gives a tight and well-adhered bond. Particularly preferably, the first and / or second adhesive strip are formed from an acrylate adhesive. Alternatively, a so-called hot melt adhesive based on synthetic resins may be used. This embodiment of the web-shaped composite seal is particularly advantageous when used as screed seal, in which the composite seal between a raw concrete floor and a screed for separation of the screed is moved from the supporting surface. The composite seal protects the screed from rising damp.

The above-described (longitudinal) adhesive strips may extend over the entire length or substantially the entire length of a composite web seal, so that the end portions or side edges of the webs can be longitudinally interconnected. In addition, it is possible to provide (transverse or end sides) adhesive strips which extend over the entire width or substantially over the entire width of the composite web-like seal so that frontally adjacent or overlapping webs can be glued together as described above. For example, an adhesive strip may have a width of 2 cm to 8 cm, preferably 3 cm to 5 cm.

If z. For example, if the (longitudinal) adhesive strips have a width (transverse to the longitudinal direction of the web-shaped composite seal) of 3 cm, adjacent webs are laid overlapping each other 3 cm as described above, so that the adhesive strips lie on top of each other and a 'glue-on-glue' Connection can be made. When connecting or bonding bituminous membranes, significantly greater overlap is required to ensure a dense sealing level. Due to the lower overlap in the connection of the composite seal described, a total of less sealing material per square meter is consumed, thus saving material and costs.

For example, when assembling the composite seal as a screed seal, the individual webs are designed and their side regions or transverse edges in the longitudinal direction as described above connected to each other. If no adhesive strips are provided along the end edges of the composite seal, the webs are designed so that the end edges of adjacent webs z. B. overlap by about 5 cm. The front edges are then connected by gluing with adhesive tapes vapor-tight. For example, adhesive tapes with a width of 100 mm or 200 mm may be used which have a butyl or bitumen based self-adhesive layer. In particular, in this embodiment the screed seal is not adhesively bonded to the entire surface (eg raw concrete).

According to a further embodiment, the composite seal is coated on one side over the entire surface or substantially over the entire surface with an adhesive, for. B. with an acrylate adhesive or hot melt adhesive as described above. In this embodiment, the composite seal can be used for example as a flat roof barrier, in which the individual webs of the composite seal are glued over the entire surface with a concrete ceiling of the flat roof. Adjacent membranes of the composite seal are laid with at least 8 cm overlap and glued to obtain a dense layer.

Particularly preferably, the adhesive coating and the adhesive strips described above are cold-bonding, so that the individual webs of the composite seal can be easily glued together and / or with a substrate. As described above, for. As an acrylate adhesive can be used. Acrylic adhesives have a high resistance to aging and temperature and are insensitive to UV radiation and oxidation. For example, between 40 to 80 g / m ^{2 of} acrylate adhesive are applied to the foam, preferably between 45 to 70 g / m ² , more preferably about 50 g / m ² . Alternatively, so-called hot melt adhesives can be used. Hot melt adhesives are based on originally non-adhesive synthetic resins, which at temperatures of z. B. be liquefied above 150 ° C and obtained by this process when re-cooled good stickiness and high adhesion. For example, acrylate adhesives can be well wet-glued and can be processed at temperatures of up to minus 10 ° C.

To protect the adhesive coating or the adhesive strips, the adhesive can be covered over the entire surface with a removable protective cover. For example, a protective cover made of paper, polyethylene (PE) or polyethylene terephthalate (PET) or a combination of these materials. The protective cover is removable for laying the composite seal.

When using the composite seal with one-sided full-surface adhesive coating, a primer can be applied between masonry and composite seal to ensure secure adhesion of the composite seal to the substrate. Masonry may be a flat roof, a floor or a wall of reinforced concrete or, alternatively, a brick wall (eg basement) as described above.

Below is described by way of example the vertical or vertical laying of a web-like composite seal with adhesive coating as described above as a moisture barrier for basement waterproofing. For substrate preparation, a primer or primer is applied thinly and evenly to the substrate or the outer wall of the cellar. The web-shaped compound seal is cut to facilitate handling before laying and laid in web width from top to bottom. For this purpose, the protective paper about 50 cm are deducted and aligned the cut sheet at an upper edge of the wall to be sealed and pressed. Then the protective paper is pulled off slowly and evenly downwards and at the same time the web is carefully glued on. Adjacent webs should be adhered at least 80 mm overlapping to obtain a tight moisture barrier. The overlap area must be carefully rolled. To protect the composite seal against mechanical damage (eg when filling the excavation pit), a protective fleece can be applied to the composite seal or insulating panels (eg perimeter panels) can be mounted on the composite seal.

Alternatively, the composite seal can be used with adhesive coating for horizontal sealing against soil moisture (eg basement floor). Before laying, the substrate is preferably precoated with a primer (see above). The moisture barrier can be cut to size prior to installation as described above or glued directly from the roll to the substrate to be sealed. Adjacent webs should also overlap at least 80 mm and be carefully rolled in the overlap area.

According to a further preferred refinement, the composite seal has at least one (outer) nonwoven layer connected to the second protective layer or the fabric layer, i. H. the nonwoven layer forms an outside of the composite seal. In this embodiment, the composite seal preferably has no adhesive coating or adhesive strips. In this embodiment, the composite seal with fleece layer is particularly suitable for use as a wall barrier, such as. z. B. as L / Z lock.

The nonwoven layer is preferably made of polypropylene (PP), polyethylene (PE), polyester, polybutylene terephthalate (PET), polybutylene terephthalate (PBT) or polyamide (PA). The fleece layer is particularly preferably in the form of a spunbonded nonwoven, in particular as a hydrophilized (water-permeable) PP spunbonded nonwoven with an areal density of, for example, 40 g / m ² . A PP nonwoven layer preferably has a surface density of between 15 g / m ² -100 g / m ² , and a PE nonwoven layer has an areal density of between 10 g / m ² -150 g / m ² . When using the composite seal, the nonwoven layer facing upwards or outwards. The surface of the at least one nonwoven layer is slightly rough or fibrous, so that here the outwardly facing surface of the nonwoven layer offers a very good adhesion ground for masonry mortar and plaster.

Instead of or in addition to the nonwoven layer, a foam layer may be provided. For example, a PE, PP, PU or plastic foam layer, which protects the composite seal against damage to bumps. Preferably, the foam layer has a thickness in the range of 0.5-3 mm, 0.75-2 mm, 0.8-1.5 mm or 0.9-1.3 mm. Alternatively or additionally, the foam layer has a basis weight of 15-300 kg / m ² , 20-200 kg / m ² , 25-100 kg / m ² or 28-50 kg / m ² .

The multilayer composite seal described above may have a basis weight of 120-300 g / m ² , preferably 130-250 g / m ^2, and more preferably 140-200 g / m ² . For example, a basis weight of or about 162 g / m ² . Ie. the multilayer composite seal is at least 5 times lighter per square meter compared to a PVC masonry barrier of the same thickness (eg 1.2 mm).

In a particularly preferred embodiment, the composite seal is a masonry barrier for use in masonry. The masonry barrier is also called a wall barrier. In the masonry arrangement, this masonry barrier (the composite seal) is provided at a masonry to block rising damp. The preferred width of the masonry barrier is: 11.5 cm, 17.5 cm, 24 cm, 30 cm, 36.5 cm or 50 cm or is in the range of 8-15 cm, 15 to 20 cm, 20 to 25 cm , 25 to 35 cm, 35 cm to 40 cm or 40 to 60 cm.

As a masonry barrier, the composite seal may preferably be used without adhesive tape and adhesive coating in, on or under a wall. For example, the composite seal can be installed as a so-called L-lock or Z-lock: In unpainted, two-shell masonry (inner shell and veneer) on the building base, the composite seal behind the veneer on the outside of the Inner shell raised. The vertically laid wall barrier track is to be led to a (previously laid) horizontal wall barrier track with a corresponding overlap or is glued to it, so that no moisture bridges arise. Alternatively, the horizontal and vertical part of the wall barrier (one-piece) can be laid out of a track, ie in one step horizontal barrier and vertical barrier are laid. In this embodiment, no connections and overlaps between a horizontal and vertical part of the masonry block or composite seal must be provided.

In a further, particularly preferred embodiment, a plurality of adjacent webs of the composite seal are provided as a surface seal. The composite seal is advantageously provided as a planar vapor barrier for sealing flat roofs, trapezoidal roofs, concrete surfaces (eg raw concrete ceilings). The adjacent composite sealing sheets are preferably overlapping as described above. Preferably, each web for the planar sealing arrangement has a width in the range of 80 to 150 cm, 100 to 180 cm, 120 to 220 cm, 140 to 250 cm, or 150 to 300 cm.
