Definitions

• a disadvantage of this solution is that the adhesive tape becomes detached from the sheet over time owing to return forces, and so one or more unsealed points can occur in the seal. Furthermore, the period of adhesion of the adhesive tape at the penetration point depends, in addition to the material of the adhesive, on the thoroughness of the adhesion. Owing to regular time constraints at the place of installation, the adhesive tape is generally applied without thorough application of pressure, in particular without continuous application of pressure on all adhesion points. Fixed adhesion of the adhesive tape, in particular continuous fixed adhesion of all adhesion points to the penetration and to the sheet, is thus not ensured. Pockets of air are left which are disadvantageous for a long-lasting adhesive effect. As a result, a high level of sealing tightness cannot be achieved.
• a sealing tape and a method for producing such a sealing tape are known from European patent application EP 2 873 700 A1 which relates to a different type.
• This sealing tape is provided for use in road construction and thus relates to a different technical field.
• the sealing tape includes a tape body in which a bitumen-containing binder is incorporated. This sets in a reactive manner and is thus not suitable for the air-tight sealing of penetrations in buildings, in particular of component penetrations through synthetic sheets in roofs, buildings and the like, such as vapor barrier sheets or dampproof membranes which are used in the heat insulation of buildings.
• the conventional sealing tape requires for this purpose a reaction-triggering or reaction-accelerating activator in order to provide energy for the production of the reactive bitumen.
• the sealing tape is additionally used to seal a joint between a cold element and an adjoining asphalt layer which will subsequently be laid whilst hot and is used exclusively in road construction.
• the filler is formed in the manner of modeling clay for this purpose.
• An advantage of the sealing tape in accordance with the invention is that, owing to the modulating capacity and softness of the filler, pockets of air can be very effectively pushed from the adhesive region at the interface between the penetration and synthetic sheet via the adhesive surfaces at the penetration and at the sheet outwards to the two long sides and ends of the installed sealing tape, in particular said pockets of air can be moved outwards in a kneading manner and can thus be eliminated.
• the tubing is formed from a soft, vapor diffusion-resistant and water-tight material.
• the material of the at least one tubing-forming film is formed from polyethylene, polyethylene terephthalate, polyamide, polypropylene or a combination thereof, preferably as a film laminate.
• a very high level of stability for the film is advantageously achieved with the materials polyethylene and polyethylene terephthalate. Since these materials are also cost- effective to procure, a very favorable sealing tape can thus be provided.
• the film tubing has a material thickness of 50 to 120 pm, preferably 50 to 100 pm and in a particularly preferred manner 60 to 80 pm. Therefore, the film tubing has on the one hand the required solidity, even when applied in a kneading manner, and on the other hand sufficient flexibility.
• a hardening material such as epoxide resin, gypsum, dental cement or cement can also be used as the filler.
• the filler can harden at a subsequent point in time.
• this is associated with the disadvantage that the deformability is limited and the actual adhesion between the film tubing and penetration and between the film tubing and synthetic sheet is encumbered by stiffening caused by hardening of the filling compound.
• a further disadvantage is the storage capacity limited by the hardening at a subsequent point in time because the filler must still be able to be processed in a kneading manner in order to utilize the advantages. Therefore, in contrast the selection of the non-hardening materials mentioned further above is preferred.
• the interior of the tubing is filled with the filler up to at least 50%.
• the interior of the tubing is filled with at least between 60% and 100% filler, in a particularly preferred manner between at least 70% and 90%, in a further preferred manner between at least 70% and 80%.
• the filler is preferably distributed uniformly in the longitudinal direction of the tubing.
• the filler can be received, in an expedient manner, in a sheath, separate from the film tubing, preferably of a film having the above- mentioned properties, which sheath is expediently attached partially to the inner tubing wall and in the longitudinal direction of the tubing.
• the adhesive layer arranged on or applied to the outer peripheral surface of the tubing extends over at least between 20% and 60%, preferably at least between 30% and 60%, in a particularly preferred manner between 40% and 50% of the periphery of the tubing, wherein the adhesive layer extends uniformly in this peripheral region along the length of the tubing.
• the adhesive layer is provided on the outer peripheral surface over half of the periphery.
• the adhesive layer can be a double-sided adhesive tape which is applied separately to the film tubing, or an adhesive coating.
• the adhesive layer includes acrylate, in particular in a further preferred manner water- resistant, UV-crossl inked and/or modified acrylate.
• the adhesive application amount is between 80 and 250 g/m 2 , preferably 120 to 200 g/m 2 .
• the film tubing can be closed in an air-tight manner at standardized, regular or even irregular distances so that it can be cut at these points (in the manner of an ice cube pack made from film).
• the tubing is welded at regular and/or irregular distances along its length at at least one point, preferably a multiplicity of points, orthogonal to the longitudinal direction or comprises a separating wall.
• the points at which the film tubing is to be closed in an air-tight manner can thus be produced by welding at least one of these points along a tubing peripheral line or by a type of separating wall between at least two film tubing sections, specifically for portioning or cutting the length of the tubing and the filler thereof.
• sealing tape blank or section preferably prefabricated sealing tape section.
• This sealing tape blank or section is formed as a tubing from at least one film comprising a filler.
• the tubing is closed at its opposite ends and so a tubular, in itself closed blank is provided, the filler of which is preferably soft and can be modeled.
• the outer peripheral surface of the sealing tape blank is at least partially provided with an adhesive layer.
• the sealing tape blank is pre-fabricated to length. Different lengths are hereby possible, wherein these lengths are dependent on the outer circumference of the respective penetration.
• the outer periphery is 31.4 cm for a pipe diameter of 100 mm.
• the overhang is larger in an expedient manner because the periphery of the ellipse formed at the penetration point on the slanted roof is greater than the outer circumference of the pipe. Therefore, the pre-fabricated blank is measured preferably by adding the circumference of the penetration plus an overhang of at least 30, preferably at least 50, mm.
• Figure 1 shows a perspective view of a sealing tape wound in a roll in accordance with the present invention
• Figure 2A shows a cross-section through a first exemplified embodiment of a sealing tape of the present invention, wherein the tubing includes only approximately 80% filler in the interior;
• Figure 2B shows a cross-section through a tubing of a second exemplified embodiment of the invention, wherein the interior of the tubing is completely filled with filler;
• Figure 3 shows a perspective view of a sealing tape in accordance with the invention adhered at the sealing point after cutting in accordance with a third embodiment
• Figure 4 shows a cross-section through a sealing tape section attached at a penetration point.
• Figure 1 shows a sealing tape 1 in accordance with the invention which is wound in form of a roll and which is formed as a tubing 4 from at least one film.
• a filler 5 is received in the tubing 4 which is soft and can be modeled.
• the tubing On the inner side of the outer peripheral surface 6 of the tape, i.e. the side facing the wound roll, the tubing is provided at least partially with an adhesive layer 7 (not shown in figure 1).
• the tubular shape of the sealing tape 1 is flexible and so, owing to the modeling clay-like filling 5, unevenness on the outer peripheral surfaces 6 of the tubing can be seen.
• the tubing 4 is completely filled with filler 5. Since the film is flexible, the sealing tape 1 can be kneaded very effectively.
• Figure 2A shows a cross-section through the sealing tape 1 in accordance with the invention in a second embodiment. It can be clearly seen that the interior 10 of the tubing is not completely filled with filler 5. Approximately 80% of the hollow inner space of the tubing 4 is filled with filler 5, wherein the remaining 20% of the inner space 10 of the tubing is not filled with filler 5 but preferably comprises approximately up to 20% air.
• a further cross-section through a sealing tape 1 in accordance with the present invention is shown.
• the tubing 4 is completely filled with filler 5, preferably up to 100%.
• An adhesive layer 7 extends over half of the outer peripheral surface 6.
• the adhesive layer 7 can be a coating which is applied directly to the outer peripheral surface 6 of the tubing 4, e.g. by spraying.
• the tubing 4 can be formed from more than one film, and so the tubing 4 is formed as a film laminate (not shown in the figures).
• the sealing tape 1 is shown in figures 2A and 2B with a circular cross-section. It will be self-evident that the actual contour can deviate from the idealized circular illustration owing to the kneading process when applying the sealing tape 1 , cf. also figure 1.
• Figure 3 shows a penetration 2 which leads through an opening in a synthetic sheet 3, in particular a vapor barrier sheet, wherein the sheet 3 is attached to a building roof (not shown in figure 3).
• a sealing tape blank 8 in accordance with the invention as per a further embodiment of the invention is attached. This blank 8 is wrapped around the entire circumference of the penetration 2 and has an excess.
• the sealing tape cutting 8 formed in this case from a polyethylene film indicates in a partial cross-section the filling of the tubing 4 which is made of a soft material which can be modeled.
• the filler 5 is a hydrogel which is permanently soft and can be kneaded very easily. It is also readily apparent that the filler 5 is predominantly located in the region of the interface between the penetration 2 and synthetic sheet 3. By modeling the filler 5 is it is possible that this can be attached to the interface region in a precise manner. In a very simple manner, the modeled filler 5 can be pressed-on in this interface region by hand, wherein improved pressure distribution occurs on the adhesive layer 7 by means of the filler 5.
• the adhesive layer 7 is arranged on the side of the sealing tape 1 which faces the penetration 2 and the synthetic sheet 3.
• the adhesive layer 7 can now be fixedly adhered to the penetration 2 and the synthetic sheet 3 very practically by hand and above all over the entire surface, wherein pockets of air are pushed outwards by applying pressure by hand to the tubing starting from the interface - indicated by a dashed line - between the penetration 2 and the synthetic sheet 3.
• the soft filler 5 which can be modeled, the number of pockets of air can be drastically reduced or completely eliminated.
