Definitions
- the present invention relates to a sealing strip and a method for its manufacture.
- the object of the present invention is to provide a sealing strip which has improved thermal insulation properties and at the same time has the known quality of EPDM (ethylene propylene diene rubber) seals.
- EPDM ethylene propylene diene rubber
- a sealing strip for sealing an intermediate space between a first component and a second component, in particular for windows or doors, with a cross-section that is essentially constant along a profile sheet or profile direction (A), the sealing strip being in a sectional plane lying transversely to the profile sheet a functional area formed from a first EPDM cellular rubber and an insulating area (which can also be referred to as an insulating area) formed from a second EPDM cellular rubber, the first EPDM cellular rubber and the second EPDM cellular rubber having different properties.
- the sealing strip can be a strand-like body, which has its greatest extension along or parallel to the profile sheet. Along this extension or profile sheet, the sealing strip can preferably have a constant cross section or a constant cross-section distribution in the functional area and in the insulating area.
- the wording "essentially constant cross-section" includes smaller local deviations, such as notches or incisions, which can be made at periodic intervals along the profile sheet on the sealing strip. These can serve to improve the ability of the sealing tape to be laid in corners.
- the first component can be a window sash, for example, whereas the second component can be a frame, in particular a blind frame or window frame, in which the window sash is held. Furthermore, the first component can be a door leaf and the second component can be a door frame.
- the first component can be a window sash and the second component can be a pane of glass held by the window sash.
- the sealing tape can bring about damping and/or insulation by sealing the intermediate space. Insulation can prevent or limit the propagation of energy (ie heat or sound). Thus, an insulating effect can be achieved.
- damping can be a conversion of kinetic energy into another, no longer relevant form of energy (ie energy dissipation can be achieved). For example, when sound is insulated, sound transmission can be prevented by reflection. On the other hand, when the sound is dampened, the sound energy can be converted into heat. The following is not expressly distinguish between insulation and damping, since both effects can be caused by the same characteristics.
- EPDM abbreviated ethylene-propylene-diene
- M group includes terpolymers of ethylene, propylene and an unspecified diene.
- EPDM is one of the synthetic rubbers with a saturated main chain (according to DIN ISO 1629: M group).
- EPDM rubbers can have double bonds in the side chains and can therefore be sulfur vulcanizable.
- the use of EPDM is advantageous because EPDM has high weather and ozone resistance as well as high thermal stability. It also has an advantageous chemical resistance to polar media (such as water or alcohol).
- EPDM only has a low impact on the environment during production, processing and use, which is why it also meets the latest environmental standards.
- EPDM is characterized by favorable processability and low material costs. Furthermore, a sufficient permanent elasticity of EPDM is to be mentioned as an advantageous property for a sealing strip in the sense of the present invention.
- the EPDM is in the form of foam rubber.
- the foam rubber can be a largely closed-pore and elastic foam and belong to the pore rubbers.
- the sponge rubber can be produced from EPDM with the addition of propellant gases. Sponge rubber can be embossed EPDM, for example.
- the manufacturing process of the first cellular rubber for the functional area can differ from the manufacturing process of the second cellular rubber for the insulating area, so that, for example, a cellular rubber with a larger pore space is provided in the insulating area.
- foam rubber is characterized by its advantageous thermal insulation properties. It is particularly advantageous that the entire functional area and insulating area are made exclusively of foam rubber.
- the insulating area can be arranged in the intermediate space such that it faces an outside (ie, for example, a side exposed to the environment) of the first and the second component.
- the insulating area can have mainly insulating properties.
- the functional area can face an inside of the first and the second component and mainly have mechanical properties such as locking the sealing tape in the gap and/or blocking a passage through the gap. Nevertheless, the functional area can also have insulating properties.
- the different properties of the first EPDM sponge rubber and the second EPDM sponge rubber can be, for example, a different density, elongation, tensile strength, elasticity, thermal conductivity, hardness, compression set at 100° C., compression set at -25° C., tensile strength and/or elongation.
- the density of the functional area can be higher than that of the insulating area by a factor in the range from 2 to 5, in particular in a range from 3 to 4.5.
- the elongation, tensile strength and resilience can be negligible.
- the properties mentioned should reach a certain minimum value.
- the functional area can advantageously fulfill its main function, namely to hold the sealing tape at a desired position.
- the insulating area can advantageously fulfill its main function, namely providing an insulating or isolating effect.
- the first sponge rubber can have an elongation of more than 100%.
- the second sponge rubber can have an elongation in a range from 0 to 200%.
- the elongation can be a relative change in length (ie an elongation or a shortening) of a body under load relative to a state without load.
- the first cellular rubber and the second cellular rubber can be connected to one another during a manufacturing process, for example.
- the sealing strip can be produced by a coextrusion process.
- the first foam rubber and the second foam rubber can be brought together before leaving a profile nozzle, which defines the desired cross section of the sealing strip.
- the profile nozzle can then define the shape of the functional area and the insulating area.
- the sealing tape according to the invention can be provided, which realizes the two contradictory properties, mechanical strength and durability as well as improved insulating properties by less strong material, in one sealing tape.
- the insulation area can be designed more simply and thus more cost-effectively.
- the functional area can preferably have a fastening section with which the sealing strip can be fixed to the first component or the second component.
- the fastening section can be designed to be brought into engagement with a complementary element formed on the first or the second component, it being possible for the fastening section to be held in the complementary element, in particular in a slot or a joint, preferably in a positive and/or non-positive manner .
- the fastening section can be designed in the form of a barb, so that it ensures a secure and permanent hold on the complementary element of the first or the second component.
- the functional area can have a support section which is supported on the first or the second component. The support section is preferably supported on the same component on which the fastening section is also fixed.
- the support section and the fastening section can expediently be arranged in such a way that the functional area is fixed in a tensioned manner on the first or the second component.
- the fastening section can fix the functional area in the manner of a barb, whereas the support section presses against the first or the second component.
- the compressive force required for this can be brought about by the geometric shape of the support section and/or by the material properties of the support section. In this way, the functional area and thus the entire sealing strip can be securely fixed without the sealing strip wobbling or being able to slip. Furthermore, tolerances in the manufacturing process of the functional area can thus be compensated for and a secure hold of the sealing strip can nevertheless be achieved.
- a support section can be formed on the insulating area from the first foam rubber or the second foam rubber.
- the functional area and the insulating area can be connected to one another, it being possible for a connecting line to be formed between the functional area and the insulating area.
- the connection can be materially bonded, for example in that the sealing tape is coextruded.
- the connecting line can have a force transmission section, in which the connecting line extends essentially in a straight line.
- the section of the connecting line via which force is transmitted from the fastening section to the insulating area indirectly via or through the functional area can preferably be regarded as the force transmission section.
- the straight extension of the connecting line in the force transmission section has the advantage that stress peaks in the material can be avoided both in the functional area and in the insulating area and in particular in the contact area of the two areas.
- the term essentially straight means that the connecting line in the force transmission section, in particular at its distal ends, can certainly have small curves, in particular in order to achieve particularly low-stress transitions to the adjacent areas of the connecting line.
- the fastening section is arrow-shaped, with the arrow-shaped geometry of the fastening section engaging in a corresponding undercut on a frame (as an example of the first or second component) and being able to form a positive and/or non-positive engagement.
- the fastening section can be designed symmetrically to a line of symmetry.
- the line of symmetry can advantageously divide the functional area into two halves of equal size. In this way it can be ensured that the force transmitted by the fastening section is transmitted to the functional area in equal parts on the right and on the left side of the fastening section.
- the functional area and/or the insulating area can have a projection, in particular a lip, which is designed to come into contact with the first or the second component.
- the projection can serve to create a connection between the sealing strip and the first component or the second component, in particular to prevent or at least reduce the passage of gas (in particular air).
- the protrusion can cause the intermediate space to be mechanically blocked.
- the sealing strip can establish a connection between the first component and the second component, which connection traverses the gap.
- the first or the second component can be in contact with the fastening portion, whereas the other of the first or the second component is in contact with at least the projection.
- the projection can be designed in such a way that it comes into contact with the first or the second component in a prestressed manner.
- the pretensioning can be effected by the projection being inclined or bent in a direction such that the first or the second component at least partially displaces the projection relative to the functional area in a mounted state of the sealing strip, compared to an unmounted state of the sealing strip.
- the projection can have an elastic restoring force, so that the projection can apply a restoring force, which counteracts the direction of displacement, during a displacement.
- the elastic restoring force can be brought about by material properties of the respective foam rubber and/or by a geometric shape of the projection. As a result, a secure sealing of the intermediate space can be achieved, since secure contact of the projection with the first component or the second component is always guaranteed.
- the protrusion is provided on the functional area.
- the projection is provided on the insulating area. It is also conceivable that a projection is provided on the functional area and on the insulating area. In this case, the projection can protrude from the functional area and/or the insulating area into the intermediate space.
- the Insulating area and/or the functional area have a contact section. The projection can be part of the abutment section. The contact section can be wavy.
- the contact section can preferably be designed to come into contact with the first or second component, in particular with a pane.
- the contact section can reliably contact a surface that is not perfectly flat, in that the wavy contact section adapts to the shape of the surface.
- the abutment section can have a substantially sinusoidal geometry.
- a wave crest of the wavy contact section particularly preferably has a smaller extension than the projection or projections. In this way it can be ensured that the projection can always shield the contact section against external influences due to its greater extension in the direction of the first or second component and thus a particularly flawless contact of the contact section with the first or second component can be ensured. In this way, it is possible in particular to prevent grains of dust or liquids from getting into the area between the contact section and the first or second component.
- the first EPDM sponge rubber can have a density in a range from 0.1 to 2.0 g/cm 3 , in particular from 0.4 to 1.5 g/cm 3 .
- This density range has turned out to be advantageous because a sufficiently high resistance to physical and chemical influences, such as impacts, vibrations and temperature differences can be achieved and at the same time a basic insulating function can be ensured.
- the functional area which is formed from the first cellular rubber, can be exposed to higher mechanical loads than the insulating area. Nevertheless, the functional area can provide a certain sealing function through the selection of the density area, so that the sealing tape can provide an improved sealing effect overall.
- the second EPDM sponge rubber can have a density in a range from 0.05 to 1.0 g/cm 3 , in particular from 0.1 to 0.4 g/cm 3 .
- a very high insulating effect can be achieved in this area, so that the insulating area is responsible for a high degree of insulation of the sealing tape.
- other material properties such as, for example, the mechanical resilience, are negligible in the insulating area, since the functional area assumes these functions in the sealing tape according to the invention.
- the functional area and/or the sealing area can define at least one cavity that extends in the profile sheet.
- the functional area and/or the insulating area can surround at least one cavity in the cross section of the sealing strip or at least one cavity can be provided in the functional area and/or insulating area.
- the hollow space can be designed in such a way that the overall geometric stability of the sealing strip is increased.
- the cavity can improve the insulating properties.
- the stability and, on the other hand, the sealing property of the sealing strip can be improved by the hollow space.
- the cavity can have an essentially rectangular shape in cross section.
- several cavities can also be provided, in particular five cavities can be provided.
- the functional area can expediently have two cavities, one of which is preferably arranged in the fastening section.
- the insulation area can have three cavities. In an alternative embodiment, five cavities can be provided in the insulation area.
- the first EPDM sponge rubber may have a hardness greater than 40 Sh A and/or the second EPDM sponge rubber may have a hardness less than 40 Sh A.
- the functional area can provide its function (i.e. holding the sealing strip and providing a seal between the first component and the second component) while being sufficiently resistant to wear.
- the first EPDM cellular rubber can have a tensile strength greater than 5 N/mm 2 and/or the second EPDM cellular rubber can have a tensile strength in a range from 0 to 5 N/mm 2 .
- the mechanical resilience of the Functional area and the insulating area can be designed for the respectively assigned main function.
- the resilience of the first sponge rubber can be about 1.5-3 times the resilience of the second sponge rubber. The preferred ratio of the resilience ensures that the functional area, which has to absorb the higher, often fluctuating forces during use, achieves the same service life as the insulating area.
- the reliability of the sealing tape as a whole can be increased.
- the first EPDM sponge rubber can have a thermal conductivity in a range from 0.05 to 0.5 W/(mK), in particular from 0.08 to 0.35 W/(mK), and/or the second EPDM sponge rubber can have a Have thermal conductivity in a range from 0.01 to 1.0 W/(mK), in particular from 0.01 to 0.08 W/(mK).
- the thermal conductivity also called thermal conductivity coefficient, can be a material property that determines the flow of heat through the first foam rubber and the second foam rubber due to heat conduction.
- the thermal conductivity shows how well a material conducts heat or how well it is suitable for thermal insulation. The lower the value of thermal conductivity, the better the thermal insulation.
- the sealing strip according to the invention can be formed by a step of coextrusion, so that the first cellular rubber and the second cellular rubber are brought together to form the sealing strip.
- the first EPDM cellular rubber and the second EPDM cellular rubber can thus preferably be formed together.
- the constant formation of the functional area and the insulating area along the profile sheet favors the production of the sealing strip Co-extrusion, since particularly simple geometries can be provided on both extrusion dies.
- a particularly high level of skill in connecting the functional area and the insulating area can be achieved by co-extrusion.
- the very good cross-linking of both foam rubbers contributes in particular to this.

- the first foam rubber has a density that is approximately 4 times higher than that of the second foam rubber.
- the functional area has two cavities or recesses 6 which extend in the profile sheet A. A cavity 6 is arranged in the fastening section 4 .
- the insulating area 3 has three further cavities 6 which also extend along the profile sheet A.
- the functional area 2 has a support section 7 which interacts with the fastening section 4 in such a way that when the sealing strip 1 is fixed to a component, the sealing strip is braced against the component in order to be held securely thereon.

- the sealing strip 8 can be additionally secured against detachment on a component to which it is attached.
- the hook section 8 interacts with a further undercut on the respective component.
