Definitions
- the present invention is a novel, flexible, to various sealing contours and sizes, e.g. Rohr penbowitch applicable, preferably self-adhesive equipped, present in roll form and processable in the form of a flexible, elastic sleeve seal material consisting of the composite of at least one flexible, elastic plastic such. a TPE and at least one nonwoven fabric.
- the material should ensure complete air and moisture tightness of the contour to be sealed.
- the collar can be either adhesive or non-adhesive.
- the particular advantage of such a gasket is that it does not require a prefabricated grommet, sealing lip or a prefabricated sealing collar, but it forms itself due to their special material properties and thus is flexible adaptable to each passage body.
- Sealing collars are known in many forms both from the practical application and from the patent literature. They are used to seal openings in walls of all kinds, mainly in the construction sector (eg pipe penetrations or cable penetrations). Such penetrations must be made airtight in accordance with the provisions of the Heat Insulation Ordinance (EnEV). As a rule, these sealing collars are made as Autowarn of an elastic material or a plastic plate having a centrally disposed opening or a plurality of openings distributed in the plate and a either only this opening or even the entire plastic plate surrounding pronounced sealing collar or a sealing grommet.
- EnEV Heat Insulation Ordinance
- an air-tight and moisture-proof sealing of, for example, cables is effected through a passage opening, such as a wall, as described in DE 20 2010 006 034 U1 and DE 20 2010 007 695 U1.
- a grommet is glued to increase the tightness with the material that is penetrated.
- the butt ends are designed to increase the air-tightness overlapping, described or cuffs with several successively arranged sealing lips, as well as cuffs that are designed from the outset on specific sealing contours (conical, angular, etc.) or those which are in firm connection with a sealing grommet or a kind of sealing base be applied to the body.
- either the diameter of the grommet is not variable, but already determined from the outset and the seal so that only applicable for certain contours or sizes or grommet and surrounding collar are slotted in L jossachsraum continuously, the slot then in the use position in the Normally sealed vapor-tight by gluing.
- rubber-elastic sealing grommets which are pushed over the ends of sealing tubes for wall penetrations of cables and finally materially connected to the wall.
- spout and sleeve in conjunction with permanently viscous or thermosetting sealants claimed, inter alia, in DE 100 53 115 Cl.
- Replacement Blade especially with sealant and / or adhesive impregnable side strips of fabric, non-woven and / or bituminous mass are attached as a primer, whereby the edge portions of the joint tape are no longer stretchable in contrast to the central portion.
- DE 10151731 AI treats a one-sided self-adhesive flexible sealing tape, in particular on butyl or acrylic basis for the sealing of component passages through plastic films on roofs, in which the band is covered on one side with a stretchable carrier film made of plastic, preferably polyethylene and in particular polyamide, so that sealing tape and carrier film are designed stretchable.
- WO 2006/066034 A2 has a self-adhesive flange material consisting of an adhesive layer between an upper and a lower, firmly bonded to the adhesive layer cover of fleece, films, coated paper, non-woven film laminates, plastic or metal on the subject, the covers the Not completely cover the adhesive layer, but each one edge zone of the adhesive remains free of the respective cover.
- EP 2031141 A1 relates to an adhesive tape for closing or sealing gaps and joints comprising at least two longitudinal strips extending parallel to one another in the longitudinal direction, one of these longitudinal strips having a greater extensibility at least in the longitudinal direction of the adhesive tape than a second of these longitudinal strips and the second longitudinal strip is not or only weakly stretchable.
- thermoplastic elastomeric film material As far as the sealing material itself is concerned, none of these protective rights addresses the use of thermoplastic elastomeric film material and its possible advantages in contrast to the materials described in the prior art.
- the object of the present invention is thus to provide a reliable seal of e.g. To achieve pipe penetrations with the simplest installation.
- the material must have a high elasticity, a low permanent elongation, a high tear propagation resistance and water resistance and durability.
- Such material properties are achieved in the case according to the invention by the use of a suitable transverse and / or longitudinally elastic sealing material, which consists essentially of at least
- Another advantage of such a composite material is that it does not tend to fray because there are no fiber-like fabrics or the like in the TPE.
- TPE and nonwoven it is important to note that in addition to their specific material characteristics and in addition to process parameters such as temperature profile and cooling, the thicknesses of the TPE and the type of fleece are particularly important for the laminating process: the thicker the TPE was extruded, the more temperature-resistant must be the nonwoven, since with increasing layer thickness of the TPE, of course, the necessary heat to the nonwoven during laminating increases.
- TPE materials according to the invention have shown that many conventional nonwoven types with a melting range of less than 130 ° C. are not usable because they tend to melt at correspondingly high production temperatures in the laminating process.
- FIGS. 1 cross-section
- 2 top view
- the TPE material is fed in granular form to the extruder.
- the material is melted and the melt is homogenized materially and thermally.
- the material melted in this way is discharged via the nozzle as a film or as a film with a basis weight of about 110 g / m 2 (1).
- the fleece (2) is fed to the TPE film via rollers and laminated together.
- the TPE fleece laminate (6) is now cooled and wound up by means of several cooling and withdrawal rollers. Shortly before winding the material is trimmed edge and cut to the desired width. When winding, the fleece is on the outside.
- the TPE material (1) is preferably SEBS (styrene-ethylene-butylene-styrene).
- SEBS styrene-ethylene-butylene-styrene
- Thermoplastic elastomers are plastics that behave at room temperature comparable to the classic elastomers, but can be plastically deformed under heat and thus show a thermoplastic behavior. In some areas, they have physical crosslinking points that dissolve when exposed to heat, without the macromolecules decomposing. Therefore, they can be processed much better than normal elastomers.
- SEBS flexible or elastic plastics
- other flexible or elastic plastics may also be used here, such as e.g. SIS, SBS, SEPS or coextruded plastics, if necessary with additives such. UV stabilizers modified.
- the SEBS-TPE is naturally excellent in weather, temperature and ozone resistance, and is resistant to water, acids, bases, alcohols, detergents and UV, whereas hydrocarbons (eg oil and fuels) can undergo structural changes upon prolonged contact cause.
- hydrocarbons eg oil and fuels
- TPEs are coextruded or otherwise bonded to other materials, the SEBS always causing the elastic phase and thus the degree of softness in such a composite.
- Such permanently soft-elastic materials or material composites and their production processes are known in principle, in particular from products and industrial property rights in the field of hygiene applications,
- Replacement Blade eg as an elastic component in diapers / diaper ears or from medial applications (gloves, face masks, surgical drapes, production of soft handles, eg for walking aids and other handles) or generally as an elastification or impact modifier component.
- SEBS is generally well suited for bonding with polyolefin plastics, tear strength, elasticity and service life meet the ever increasing demands of the industry.
- the preferred styrenic block polymers herein are basically three blocks: two styrene endblocks as relatively hard components and a soft hydrogenated midblock of ethylene-butylene.
- the mechanical properties allow applications of 40 ° C. up to 120 ° C, the compression set and tensile set values as well as the dynamic fatigue strength of the material are excellent.
- the compression set (DVR) indicates to what extent a deformed material returns after a certain time and temperature.
- a DVR of e.g. 0% indicates that the material has returned to 100%, ie fully reset, at a DVR of e.g. 100%, the material to 0%, so not reset.
- DVR values are important, e.g. in sealing applications or damping elements.
- the tensile set (ZVR) is the percentage of permanent deformation of a specimen that remains after relief.
- Dynamic fatigue strength refers to the ability of a material to withstand stresses due to dynamic forces without fatigue damage.
- the SEBS carries the main function of the laminate. It is responsible for the elasticity, the tear propagation resistance and the tightness. Essentially, the nonwoven fulfills the function of a processing aid: it prevents the pure TPE film from blocking due to its inherent tackiness. In addition, the fleece also improves the tear resistance of the laminate.
- the nonwoven used here in first experiments is a hydroentangled, highly tear-resistant, flexible spunbonded non-woven based on polypropylene with a weight per unit area of about 35 g / m 2 , but further tests have shown that
- Test specimen width 60 mm
- Clamping length 40 mm
- Exhaust speed 300 m / min
- the tensile strength in the longitudinal direction was between 2 and 5 MPa and the elongation at break in the longitudinal direction between 30 and 250%.
- the tear strength in the transverse direction was 0.5 to 4 MPa, the transverse elongation at break between 200 and 600%.
- an opening in the full-surface sealing material (6) can be cut free by hand, so that it is suitable for any desired size of pipe penetrations and thus openings to be sealed.
- both the current size of an opening adapted pattern in printed on the laminate shape are advantageous as well as already punched into the laminate holes.
- TPE (1) it is also quite possible to cover the TPE (1) not only on one side, but on both sides with a fleece (2), in which case also quite different nonwovens can be used.
- a fleece (2) in which case also quite different nonwovens can be used.
- several layers of suitable TPE and nonwoven materials for the sealing material according to the invention can be laminated together, with it
- the optional adhesive equipment of the material is laminated in a separate operation, either over the entire surface or in the form of a transfer adhesive strip or several such strips (3) or in the form of adhesive dots, covered by an adhesive-repellent liner material (4). If transfer adhesive strips are used, they are preferably applied to the edge of the TPE nonwoven laminate (6) which has already been cut to the desired width. The laminated with the transfer adhesive tapes laminate is wound up again. However, depending on the application, it may also be advantageous not to apply any adhesive to the laminate.
- Preferred adhesives for application to the laminate are transferless adhesive tapes (3) in the form of a solvent-free hotmelt adhesive based on synthetic rubber in a thickness of at least 0.20 mm, since such pressure-sensitive adhesive tapes have a high initial adhesion and final strength and because of the higher adhesive application even on rough materials very Adhere well, but also especially on low-energy plastics such as polyethylene and polypropylene.
- Such adhesives have a good heat resistance of about -30 to about + 70 ° C, they are quite resistant to aging and moisture insensitive and also have a high resistance to UV radiation and oxygen.
- carrier-based pressure-sensitive adhesive tapes can also be used, whereby, just as in the case of transfer adhesive tapes, the side of the adhesive tape not bonded to the nonwoven is covered until it is used with a release liner (4).
- the sealing material is in roll form.
- the rolls can be perforated transversely (5) at a certain distance to allow strip of the sealing sleeve material to be easily detached from the roll
