Definitions
- the present invention relates to a panel with a swellable sealing lip and an arrangement of panels with a swellable sealing lip, a method for producing a panel with a swellable sealing lip and the use of a swellable material for sealing panels.
- Panels with retaining profiles are known per se and can be used in particular as decorated wall or floor panels, the term wall panel also being understood to mean panels which are suitable for covering ceilings or doors. They usually consist of a carrier or core made of a solid material, for example a wood-based material, plastic or composite material, which is provided on at least one side with a decorative layer and a cover layer and optionally with further layers, for example a wear layer arranged between the decorative and cover layer .
- the decorative layer is usually a printed paper that is impregnated with a resin.
- the top layer and the other layers are usually made of resin.
- Such known panels have retaining profiles on the panel edges in a manner known per se.
- the holding profiles hold the panels together in the installed state by means of a positive connection.
- Various holding profiles are known. Simple fillings have a simple groove and a complementary bung that act perpendicular to the panel plane. More complex holding profiles are known, in particular, for panels for glueless installation.
- the complementary holding profiles are from two to connecting panels designed so that the positive connection by hooks and undercuts also prevents the panels from being pulled apart.
- the panels can therefore be installed floating, so they do not have to be glued to the floor and they do not have to be glued together. This makes laying such panels particularly easy and quick, and the laid floor can also adapt to a certain extent to unevenness in the floor due to the flexibility of the connections and can also react to temperature fluctuations.
- the moisture protection of such panels may therefore still offer room for improvement. There is room for improvement in particular in the Longevity of moisture protection and in the simplicity of using a moisture protection result.
- the invention proposes a panel with a swellable sealing lip.
- the panel comprises a panel top and a panel underside as well as at least four panel edges lying opposite one another in pairs, with complementary retaining profiles provided in pairs on the opposite panel edges, the retaining profiles being designed such that further panels with a complementary retaining profile can be attached to a retaining profile of a panel, at least one of which Holding profile at least partially has a swellable sealing lip along its longitudinal axis.
- panel in the sense of the invention is to be understood in particular as wall, ceiling, door or floor panels. These can have a decor that imitates a decorative template and is applied to a carrier plate. Decorative panels are used in a variety of ways, both in the interior of rooms and for decorative cladding of buildings, for example in trade fair construction. One of the most common areas of application for decorative panels is their use as flooring. The decor panels often have a decor that is supposed to emulate a natural material.
- the term "swellable" is to be understood as the property of a material to swell by absorption of gas or liquid or to increase its volume.
- the volume increase can be, for example, a doubling or a tenfold increase in volume.
- sealing lip is to be understood as an elongated device which can hydraulically seal two surfaces lying against one another.
- panel edge is to be understood as the surface which connects the top side of the panel to the underside of the panel.
- holding profile is to be understood as the geometric configuration of the panel edge. The term also includes multi-part holding profiles.
- complementary holding profile is to be understood as a holding profile whose geometric configuration essentially supplements that of another holding profile. In other words, a holding profile that has recesses essentially where the other holding profile has savings and vice versa. Two complementary holding profiles can therefore be attached to one another in a form-fitting manner. Cavities can remain between the complementary holding profiles.
- a holding profile can be a groove and a complementary holding profile has a bung, or a holding profile can have a hook and a complementary holding profile has a corresponding undercut, or both holding profiles have hooks and undercuts.
- a previously described panel thus serves in particular to protect against the penetration and penetration of liquids at panel joints.
- a panel according to the invention comprises a panel top and a panel underside as well as at least four panel edges opposite one another in pairs.
- Complementary retaining profiles are provided in pairs on the opposite panel edges, the retaining profiles being designed in such a way that further panels with a complementary retaining profile can be attached to a retaining profile of a panel. In other words, several such panels can be laid on one surface and connected to one another via the complementary holding profiles.
- the panels according to the invention are characterized in that at least one holding profile has a swellable sealing lip along the longitudinal axis.
- the means for protection against penetration and penetration of liquids at panel joints does not have to be made available during installation.
- the panels according to the invention can therefore be installed in exactly the same way as panels without a swellable sealing lip, but at the same time, after installation, offer improved protection against penetration and penetration of liquids at panel joints.
- the swellability of the sealing lip means that no permanent, additional stresses act on the connection of the holding profiles joined together, and that additional stress is only generated when the sealing lip swells, if necessary. This means that the connections remain flexible at the same time allow improved protection against penetration and penetration of liquids at panel joints.
- the swellable sealing lip essentially consists of a material swellable by absorbing aqueous liquids.
- Aqueous liquids can be, for example, rain water, dirty water, drinks, cleaning water, washing water, sweat or urine.
- the swellable sealing lip consists essentially of a water-insoluble polymer.
- the swellable sealing lip has a water-absorbing material selected from the group consisting of: superabsorbers, acrylonitrile copolymers, polyacrylamide copolymers, ethylene-maleic anhydride copolymers, polyvinyl alcohol copolymers, or combinations thereof. It can also be provided in one embodiment of the invention that the swellable sealing lip has a water-absorbing material selected from the group consisting of: crosslinked carboxymethyl celluloses, compressed celluloses, modified celluloses, cellulose ethers, bran or combinations thereof.
- the swellable sealing lip swells particularly well and therefore cannot be particularly thin, is particularly thin, and can be easily processed and / or attached.
- the swellable sealing lip consists essentially of a material which forms hydrogels with water.
- the swellable sealing lip has a binder.
- a binder is understood to mean a material that can hold particles of a material together.
- the binder can be, for example, an elastomer, which is in the form of a powder or a fiber.
- the swellable sealing lip extends along the entire length of the holding profile.
- At least one holding profile of each of the complementary holding profiles has a swellable sealing lip.
- At least one holding profile of each pair of opposing complementary holding profiles has a swellable sealing lip. This means that at least half of the holding profiles have a swellable sealing lip. For a panel with four panel edges, this means that it is provided that at least two non-opposite holding profiles have a swellable sealing lip.
- all holding profiles have a swellable sealing lip.
- the swellable sealing lip is attached to the holding profile in a material, non-positive or positive manner.
- the sealing lip does not inadvertently separate from the panel before laying.
- the sealing lip does not unintentionally detach from the panel during transport, storage or cutting of the panels.
- a cohesive connection can in particular make it possible for the swellable sealing lip to be attached to the holding profile at any point. This advantageously also allows the attachment of a swellable sealing lip at filigree points on the holding profile.
- An adhesive can be provided for a material connection. It can thereby be achieved that a powdery sealing lip can also be attached to the holding profile.
- a sealing lip with a particularly large cross-section can be attached to the holding profile.
- a particularly large absolute change in volume when the sealing lip swells can thereby be achieved.
- a groove can be provided, into which a sealing lip can be pressed.
- the swellable sealing lip is essentially flush with the holding profile.
- Attaching a further panel with a complementary holding profile has a clearance fit or transition fit to the complementary holding profile of the further panel.
- the swellable sealing lip is arranged in the holding profile of the panel edge in such a way that the swellable sealing lip, after attachment of a further panel with a complementary holding profile, after swelling, rests in a hydraulically sealing form on the complementary holding profile of the further panel .
- the invention also proposes an arrangement of at least two panels with a swellable sealing lip.
- the panels have complementary holding profiles on facing panel edges and are attached to one another by the complementary holding profiles.
- the arrangement is characterized in that at least one of the mutually facing complementary holding profiles has a swellable sealing lip along the longitudinal axis, and the swellable sealing lip has a clearance fit or transition fit to the complementary holding profile of the other panel edge, the swellable Sealing lip after absorption of an aqueous liquid, in a hydraulically sealing form against the complementary holding profile of the other panel edge.
- each panel joint has a swellable sealing lip and it can be achieved that if necessary, that is when a liquid comes into contact with the joint, the panel joint is sealed by the swelling of the sealing lip without any additional Tensions act on the connection of joined holding profiles.
- the invention also proposes a method for producing a panel with a swellable sealing lip.
- a position for attaching the swellable sealing lip can already be provided when the holding profile is formed.
- the swellable sealing lip can also be adapted to the holding profile.
- the swellable sealing lip can be applied before or after the application of a decorative layer and a cover layer and, if appropriate, further layers, for example a wear layer arranged between the decorative and cover layer.
- the carrier can be made of a material that is customary for panels.
- the invention further proposes to use a swellable material for sealing panels.
- a swellable material is used to seal the panels described above.
- the panel joints are sealed by swelling of the material only when needed, i.e. when a liquid comes into contact with the joint, without additional stresses first acting on the connection of the holding profiles joined together.

Es wird ferner eine Anordnung derartiger Paneele, ein Verfahren zur Herstellung solcher Paneele und die Verwendung eines Materials zum Abdichten derartiger Paneele vorgeschlagen.

Description
Die vorliegende Erfindung betrifft ein Paneel mit quellbarer Dichtlippe, sowie eine Anordnung von Paneelen mit quellbarer Dichtlippe, ein Verfahren zur Herstellung eines Paneels mit quellbarer Dichtlippe und die Verwendung eines quellbaren Materials zum Abdichten von Paneelen.The present invention relates to a panel with a swellable sealing lip and an arrangement of panels with a swellable sealing lip, a method for producing a panel with a swellable sealing lip and the use of a swellable material for sealing panels.
Paneele mit Halteprofilen sind an sich bekannt und können insbesondere als dekorierte Wand- oder Bodenpaneele verwendet werden, wobei unter dem Begriff Wandpaneel auch Paneele zu verstehen sind, die zur Decken- oder Türbekleidung geeignet sind. Sie bestehen üblicherweise aus einem Träger beziehungsweise Kern aus einem festen Material, beispielsweise einem Holzwerkstoff, Kunststoff oder Kompositmaterial, der auf mindestens einer Seite mit einer Dekorschicht und einer Deckschicht sowie gegebenenfalls mit weiteren Schichten, beispielsweise einer zwischen Dekor- und Deckschicht angeordneten Verschleißschicht, versehen ist. Die Dekorschicht ist üblicherweise ein gedrucktes Papier, das mit einem Harz imprägniert ist. Auch die Deckschicht und die übrigen Schichten werden meist aus Harz hergestellt.Panels with retaining profiles are known per se and can be used in particular as decorated wall or floor panels, the term wall panel also being understood to mean panels which are suitable for covering ceilings or doors. They usually consist of a carrier or core made of a solid material, for example a wood-based material, plastic or composite material, which is provided on at least one side with a decorative layer and a cover layer and optionally with further layers, for example a wear layer arranged between the decorative and cover layer . The decorative layer is usually a printed paper that is impregnated with a resin. The top layer and the other layers are usually made of resin.
Solche bekannten Paneele weisen in an sich bekannter Weise an den Paneelkanten Halteprofile auf. Die Halteprofile halten die Paneele im verlegten Zustand durch eine formschlüssige Verbindung zusammen. Dabei sind verschiedene Halteprofile bekannt. Einfache Spundungen weisen eine einfache Nut und einen komplementären Spund auf, die senkrecht zur Paneelebene wirken. Komplexere Halteprofile sind insbesondere bei Paneelen zur leimlosen Verlegung bekannt. Dabei sind die komplementären Halteprofile von zwei zu verbindenden Paneelen so ausgestaltet, dass die formschlüssige Verbindung durch Haken und Hinterschneidungen auch ein Auseinanderziehen der Paneele verhindert. Die Paneele können deswegen schwimmend Verlegt werden, müssen also nicht mit dem Boden verklebt werden, und sie müssen auch nicht miteinander verleimt werden. Dadurch ist das Verlegen derartiger Paneele besonders einfach und schnell und der verlegte Boden kann sich durch die Flexibilität der Verbindungen auch in gewissem Maße an Unebenheiten des Bodens anpassen und auch auf Temperaturschwankungen reagieren.Such known panels have retaining profiles on the panel edges in a manner known per se. The holding profiles hold the panels together in the installed state by means of a positive connection. Various holding profiles are known. Simple fillings have a simple groove and a complementary bung that act perpendicular to the panel plane. More complex holding profiles are known, in particular, for panels for glueless installation. The complementary holding profiles are from two to connecting panels designed so that the positive connection by hooks and undercuts also prevents the panels from being pulled apart. The panels can therefore be installed floating, so they do not have to be glued to the floor and they do not have to be glued together. This makes laying such panels particularly easy and quick, and the laid floor can also adapt to a certain extent to unevenness in the floor due to the flexibility of the connections and can also react to temperature fluctuations.
Ein Problem derartig verlegter Paneele ist es jedoch, dass die Fugen anfällig für den Eintritt von Flüssigkeiten sind. Dabei können Flüssigkeiten sogar durch die Fuge unter die Paneele geraten, wo sie nicht mehr erreicht und entfernt werden können, ohne die Paneele vorher zu entfernen. Dadurch kann zum Beispiel ein Schaden am Boden unter den Paneelen entstehen. Zudem kann sich zum Beispiel gesundheitsgefährdender Schimmel zwischen Paneelunterseite und Untergrund bilden. Dieser kann unentdeckt bleiben und dessen Entfernung auch sehr aufwendig sein.However, one problem with panels laid in this way is that the joints are susceptible to the ingress of liquids. Liquids can even get through the joint under the panels, where they can no longer be reached and removed without first removing the panels. This can cause damage to the floor under the panels, for example. In addition, harmful mold can form between the underside of the panel and the surface. This can remain undetected and its removal can also be very complex.
Es gibt deswegen ein Bedürfnis, die Fugen von verlegten Paneelen vor dem Eindringen und insbesondere Durchdringen von Flüssigkeiten zu schützen. Es ist bekannt, dass die Fugen beim Verlegen verleimt werden können. Dadurch ergibt sich aber der Nachteil, dass das Verlegen der Paneele mit wesentlich mehr Aufwand verbunden ist. Zudem wird dadurch die Flexibilität der Paneelverbindungen eingeschränkt. Ferner ist bekannt, die verlegten Paneele mit einer Versiegelung zu behandeln. Dabei ergibt sich jedoch der Nachteil, dass die Versiegelung nur begrenzt ein Eindringen von Flüssigkeiten in die Fugen verhindern kann und dass die Haltbarkeit der Versiegelung wesentlich kürzer als die Lebensdauer der verlegten Paneele ist und deswegen häufig neu aufgetragen werden muss.There is therefore a need to protect the joints of installed panels from the penetration and in particular penetration of liquids. It is known that the joints can be glued when laying. However, this has the disadvantage that laying the panels is associated with considerably more effort. This also limits the flexibility of the panel connections. It is also known to treat the installed panels with a seal. However, this has the disadvantage that the seal can only prevent liquids from penetrating into the joints to a limited extent, and that the durability of the seal is significantly shorter than the service life of the installed panels and therefore often has to be reapplied.
Der Feuchtigkeitsschutz solcher Paneele kann deswegen unter Umständen noch Verbesserungspotential bieten. Verbesserungspotential kann sich dabei insbesondere in der Langlebigkeit des Feuchtigkeitsschutzes und in der Einfachheit der Verwendung eines Feuchtigkeitsschutzes ergeben.The moisture protection of such panels may therefore still offer room for improvement. There is room for improvement in particular in the Longevity of moisture protection and in the simplicity of using a moisture protection result.
Es ist daher die Aufgabe der vorliegenden Erfindung, verbesserte Mittel zum Schutz vor dem Durchdringen von Feuchtigkeit oder Flüssigkeiten durch Paneelfugen bereitzustellen.It is therefore the object of the present invention to provide improved means for protecting against the penetration of moisture or liquids through panel joints.
Gelöst wird diese Aufgabe durch Paneele gemäß Anspruch 1 sowie ferner durch eine Anordnung derartiger Paneelen gemäß Anspruch 14, ein Verfahren zur Herstellung solcher Paneele nach Anspruch 15 und die Verwendung eines Materials zum Abdichten derartiger Paneele nach Anspruch 16. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen, in der Beschreibung oder den Figuren angegeben, wobei weitere in den Unteransprüchen oder in der Beschreibung oder den Figuren beschriebene oder gezeigte Merkmale einzeln oder in einer beliebigen Kombination einen Gegenstand der Erfindung darstellen können, wenn sich aus dem Kontext nicht eindeutig das Gegenteil ergibt.This object is achieved by panels according to claim 1 and further by an arrangement of such panels according to claim 14, a method for producing such panels according to claim 15 and the use of a material for sealing such panels according to claim 16. Preferred embodiments of the invention are in the subclaims , specified in the description or the figures, wherein further features described or shown in the subclaims or in the description or the figures, individually or in any combination, can constitute an object of the invention if the context does not clearly indicate the opposite.
Mit der Erfindung wird ein Paneel mit einer quellbaren Dichtlippe vorgeschlagen.The invention proposes a panel with a swellable sealing lip.
Das Paneel umfasst eine Paneeloberseite und eine Paneelunterseite sowie wenigstens vier sich paarweise gegenüberliegende Paneelkanten, mit an den gegenüberliegenden Paneelkanten paarweise vorgesehenen komplementären Halteprofilen, wobei die Halteprofile so ausgestaltet sind, dass an ein Halteprofil eines Paneels weitere Paneele mit komplementärem Halteprofil anbringbar sind, wobei zumindest ein Halteprofil zumindest teilweise entlang seiner Längsachse eine quellbare Dichtlippe aufweist.The panel comprises a panel top and a panel underside as well as at least four panel edges lying opposite one another in pairs, with complementary retaining profiles provided in pairs on the opposite panel edges, the retaining profiles being designed such that further panels with a complementary retaining profile can be attached to a retaining profile of a panel, at least one of which Holding profile at least partially has a swellable sealing lip along its longitudinal axis.
Es konnte in überraschender Weise gezeigt werden, dass derartige Paneele ohne zusätzlichen Aufwand einfach verlegt werden können und dabei verbesserten Schutz gegen Eindringen und Durchdringen von Flüssigkeiten an den Fugen aufweisen.It was surprisingly shown that such panels can be easily installed without additional effort and have improved protection against the penetration and penetration of liquids at the joints.
Unter dem Begriff "Paneel" sind im Sinne der Erfindung insbesondere Wand-, Decken, Tür- oder Bodenpaneele zu verstehen. Diese können ein auf eine Trägerplatte aufgebrachtes eine Dekorvorlage nachbildendes Dekor aufweisen. Dekorpaneele werden dabei in vielfältiger Weise sowohl im Bereich des Innenausbaus von Räumen, als auch zur dekorativen Verkleidung von Bauten, beispielsweise im Messebau, verwendet. Eine der häufigsten Einsatzbereiche von Dekorpaneelen ist deren Nutzung als Fußbodenbelag. Die Dekorpaneele weisen dabei vielfach ein Dekor auf, welches einen Naturwerkstoff nachempfinden soll.The term "panel" in the sense of the invention is to be understood in particular as wall, ceiling, door or floor panels. These can have a decor that imitates a decorative template and is applied to a carrier plate. Decorative panels are used in a variety of ways, both in the interior of rooms and for decorative cladding of buildings, for example in trade fair construction. One of the most common areas of application for decorative panels is their use as flooring. The decor panels often have a decor that is supposed to emulate a natural material.
Unter dem Begriff "quellbar" ist im Sinne der Erfindung die Eigenschaft eines Materials zu verstehen durch Aufnahme von Gas oder Flüssigkeit anzuschwellen, beziehungsweise sein Volumen zu vergrößern. Die Volumenvergrößerung kann beispielsweise eine Verdopplung oder Verzehnfachung des Volumens sein.In the context of the invention, the term "swellable" is to be understood as the property of a material to swell by absorption of gas or liquid or to increase its volume. The volume increase can be, for example, a doubling or a tenfold increase in volume.
Unter dem Begriff "Dichtlippe" ist eine längliche Vorrichtung zu verstehen, welcher zwei aneinander liegende Flächen hydraulisch abdichten kann.The term “sealing lip” is to be understood as an elongated device which can hydraulically seal two surfaces lying against one another.
Unter dem Begriff "Paneelkante" ist im Sinne der Erfindung die Oberfläche zu verstehen, welche die Paneeloberseite mit der Paneelunterseite verbindet.In the context of the invention, the term “panel edge” is to be understood as the surface which connects the top side of the panel to the underside of the panel.
Unter dem Begriff "Halteprofil" ist die geometrische Ausgestaltung der Paneelkante zu verstehen. Dabei werden unter dem Begriff auch mehrteilige Halteprofile verstanden.The term “holding profile” is to be understood as the geometric configuration of the panel edge. The term also includes multi-part holding profiles.
Unter dem Begriff "komplementäres Halteprofil" ist ein Halteprofil zu verstehen, dessen geometrische Ausgestaltung die eines anderen Halteprofils im Wesentlichen ergänzt. Also ein Halteprofil, das im Wesentlichen dort Aussparungen aufweist, wo das andere Halteprofil Einsparungen aufweist und umgekehrt. Zwei komplementäre Halteprofile sind deswegen formschlüssig aneinander befestigbar. Dabei können Hohlräume zwischen den komplementären Halteprofilen verbleiben. Beispielsweise kann ein Halteprofil eine Nut aufweisen und ein komplementäres Halteprofil einen Spund, oder ein Halteprofil kann einen Haken aufweisen und ein komplementäres Halteprofil eine entsprechende Unterschneidung, oder beide Halteprofile weisen Haken und Unterschneidungen auf.The term "complementary holding profile" is to be understood as a holding profile whose geometric configuration essentially supplements that of another holding profile. In other words, a holding profile that has recesses essentially where the other holding profile has savings and vice versa. Two complementary holding profiles can therefore be attached to one another in a form-fitting manner. Cavities can remain between the complementary holding profiles. For example, a holding profile can be a groove and a complementary holding profile has a bung, or a holding profile can have a hook and a complementary holding profile has a corresponding undercut, or both holding profiles have hooks and undercuts.
Ein vorbeschriebenes Paneel dient somit insbesondere dem Schutz gegen Eindringen und Durchdringen von Flüssigkeiten an Paneelfugen.A previously described panel thus serves in particular to protect against the penetration and penetration of liquids at panel joints.
Im Detail umfasst ein erfindungsgemäßes Paneel eine Paneeloberseite und eine Paneelunterseite sowie wenigstens vier sich paarweise gegenüberliegenden Paneelkanten. An den gegenüberliegenden Paneelkanten sind dabei paarweise komplementäre Halteprofile vorgesehenen, wobei die Halteprofile so ausgestaltet sind, dass an ein Halteprofil eines Paneels weitere Paneele mit komplementärem Halteprofil anbringbar sind. In anderen Worten können mehrere derartige Paneele auf einer Fläche verlegt werden und über die komplementären Halteprofile miteinander verbunden werden.In detail, a panel according to the invention comprises a panel top and a panel underside as well as at least four panel edges opposite one another in pairs. Complementary retaining profiles are provided in pairs on the opposite panel edges, the retaining profiles being designed in such a way that further panels with a complementary retaining profile can be attached to a retaining profile of a panel. In other words, several such panels can be laid on one surface and connected to one another via the complementary holding profiles.
Die erfindungsgemäßen Paneele sind dabei dadurch gekennzeichnet, dass zumindest ein Halteprofil entlang der Längsachse eine quellbare Dichtlippe aufweist.The panels according to the invention are characterized in that at least one holding profile has a swellable sealing lip along the longitudinal axis.
Dadurch wird vorteilhafter Weise erreicht, dass das Mittel zum Schutz gegen Eindringen und Durchdringen von Flüssigkeiten an Paneelfugen nicht erst beim Verlegen bereitgestellt werden muss. Die erfindungsgemäßen Paneele können deswegen genauso verlegt werden, wie Paneele ohne eine quellbare Dichtlippe, bieten aber nach dem Verlegen gleichzeitig einen verbesserten Schutz gegen Eindringen und Durchdringen von Flüssigkeiten an Paneelfugen. Weiterhin wird vorteilhafter Weise erreicht, dass durch die Quellbarkeit der Dichtlippe keine dauerhaften, zusätzlichen Spannungen auf die Verbindung von aneinandergefügten Halteprofilen wirken und eine zusätzliche Spannung erst durch das Quellen der Dichtlippe bei Bedarf erzeugt wird. Dadurch wird erreicht, dass die Verbindungen flexibel bleiben aber gleichzeitig einen verbesserten Schutz gegen Eindringen und Durchdringen von Flüssigkeiten an Paneelfugen erlauben.It is thereby advantageously achieved that the means for protection against penetration and penetration of liquids at panel joints does not have to be made available during installation. The panels according to the invention can therefore be installed in exactly the same way as panels without a swellable sealing lip, but at the same time, after installation, offer improved protection against penetration and penetration of liquids at panel joints. Furthermore, it is advantageously achieved that the swellability of the sealing lip means that no permanent, additional stresses act on the connection of the holding profiles joined together, and that additional stress is only generated when the sealing lip swells, if necessary. This means that the connections remain flexible at the same time allow improved protection against penetration and penetration of liquids at panel joints.
In einer Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe im Wesentlichen aus einem durch Aufnahme wässriger Flüssigkeiten quellbarem Material besteht.In one embodiment of the invention, it can be provided that the swellable sealing lip essentially consists of a material swellable by absorbing aqueous liquids.
Dadurch kann erreicht werden, dass die Paneele insbesondere einen verbesserten Schutz gegen Eindringen und Durchdringen von Flüssigkeiten, wie sie im Alltag am häufigsten vorkommen, aufweisen. Wässrige Flüssigkeiten können dabei zum Beispiel Regenwasser, Schmutzwasser, Getränke, Putzwasser, Waschwasser, Schweiß oder Urin sein.It can thereby be achieved that the panels in particular have improved protection against the penetration and penetration of liquids, as they occur most frequently in everyday life. Aqueous liquids can be, for example, rain water, dirty water, drinks, cleaning water, washing water, sweat or urine.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe im Wesentlichen aus einem wasserunlöslichen Polymer besteht.In a further embodiment of the invention it can be provided that the swellable sealing lip consists essentially of a water-insoluble polymer.
Dadurch kann insbesondere erreicht werden, dass die quellbare Dichtlippe auch nach häufigem Kontakt mit wässrigen Flüssigkeiten funktionsfähig bleibt.This can in particular ensure that the swellable sealing lip remains functional even after frequent contact with aqueous liquids.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe ein wasserabsorbierendes Material aufweist, ausgewählt aus der Gruppe bestehend aus: Superabsorbern, Acrylnitril Copolymeren, Polyacrylamid Copolymeren, Ethylen-Maleinsäureanhydrid Copolymeren, Polyvinylalkohol Copolymeren, oder Kombinationen davon. Ebenso kann in einer Ausgestaltung der Erfindung vorgesehen sein, dass die quellbare Dichtlippe ein wasserabsorbierende Material aufweist, ausgewählt aus der Gruppe bestehend aus: vernetzten Carboxymethylcellulosen, komprimierten Cellulosen, modifizierten Cellulosen, Celluloseethern, Kleie oder Kombinationen davon.In a further embodiment of the invention, it can be provided that the swellable sealing lip has a water-absorbing material selected from the group consisting of: superabsorbers, acrylonitrile copolymers, polyacrylamide copolymers, ethylene-maleic anhydride copolymers, polyvinyl alcohol copolymers, or combinations thereof. It can also be provided in one embodiment of the invention that the swellable sealing lip has a water-absorbing material selected from the group consisting of: crosslinked carboxymethyl celluloses, compressed celluloses, modified celluloses, cellulose ethers, bran or combinations thereof.
Dadurch kann erreicht werden, dass die quellbare Dichtlippe besonders gut quillt und deswegen besonders dünn sein kein, besonders gut Wasser aufnehmen kann, sowie leicht zu verarbeiten und/oder anzubringen ist.It can thereby be achieved that the swellable sealing lip swells particularly well and therefore cannot be particularly thin, is particularly thin, and can be easily processed and / or attached.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe im Wesentlichen aus einem Material besteht, welches mit Wasser Hydrogele bildet.In a further embodiment of the invention it can be provided that the swellable sealing lip consists essentially of a material which forms hydrogels with water.
Dadurch kann erreicht werden, dass Wasser, welches mit der Dichtlippe in Kontakt kommt, besonders gut von der Dichtlippe aufgenommen wird. Ferner kann dadurch vorteilhafter weise erreicht werden, dass die quellbare Dichtlippe nach der Aufnahme von Wasser nicht tropft und somit auch kein Wasser durch die Dichtlippe hindurch sickert.It can thereby be achieved that water which comes into contact with the sealing lip is particularly well absorbed by the sealing lip. Furthermore, it can advantageously be achieved that the swellable sealing lip does not drip after the absorption of water and thus no water seeps through the sealing lip.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe ein Bindemittel aufweist.In a further embodiment of the invention it can be provided that the swellable sealing lip has a binder.
Dadurch kann erreicht werden, dass auch Materialien, die üblicherweise spröde sind oder in Pulverform vorliegen, zu einer Dichtlippe verarbeitet werden können. Unter einem Bindemittel wird ein Material verstanden, welches Partikel eines Materials zusammenhalten kann. Das Bindemittel kann beispielsweise ein Elastomer sein, welches als Pulver oder als Faser vorliegt.It can thereby be achieved that materials which are usually brittle or are in powder form can also be processed to form a sealing lip. A binder is understood to mean a material that can hold particles of a material together. The binder can be, for example, an elastomer, which is in the form of a powder or a fiber.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass sich die quellbare Dichtlippe entlang der gesamten Länge des Halteprofils erstreckt.In a further embodiment of the invention, it can be provided that the swellable sealing lip extends along the entire length of the holding profile.
Dadurch kann vorteilhafterweise erreicht werden, dass die Paneelfuge über die gesamte Länge der Paneelkante gegen Eindringen und Durchdringen von Flüssigkeiten geschützt ist. Insbesondere kann dadurch erreicht werden, dass eine Dichtwirkung auch eintritt, wenn das Paneel im Zuge der Montage gekürzt wird.This advantageously means that the panel joint is protected against the penetration and penetration of liquids over the entire length of the panel edge. In particular, it can be achieved that a sealing effect also occurs if the panel is shortened in the course of assembly.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass zumindest ein Halteprofil jedes der paarweise komplementären Halteprofile eine quellbare Dichtlippe aufweist.In a further embodiment of the invention it can be provided that at least one holding profile of each of the complementary holding profiles has a swellable sealing lip.
In anderen Worten kann vorgesehen sein, dass von jedem Paar sich gegenüberliegender komplementärer Halteprofile zumindest ein Halteprofil eine quellbare Dichtlippe aufweist. Dies bedeutet, dass zumindest die Hälfte der Halteprofile eine quellbare Dichtlippe aufweist. Für ein Paneel mit vier Paneelkanten bedeutet dies, dass vorgesehen ist, dass zumindest zwei nicht gegenüberliegende Halteprofile eine quellbare Dichtlippe aufweisen.In other words, it can be provided that at least one holding profile of each pair of opposing complementary holding profiles has a swellable sealing lip. This means that at least half of the holding profiles have a swellable sealing lip. For a panel with four panel edges, this means that it is provided that at least two non-opposite holding profiles have a swellable sealing lip.
Dadurch kann vorteilhafterweise erreicht werden, dass nach der Verlegung mehrerer derartiger Paneele auf einer Fläche, alle Paneelfugen zumindest eine quellbare Dichtlippe aufweisen. Dadurch kann erreicht werden, dass alle Paneelfugen und insbesondere auch die Punkte an denen zwei Fugen, beziehungsweise drei Paneele, aufeinandertreffen gegen Eindringen und Durchdringen von Flüssigkeiten geschützt sind.This advantageously means that after the laying of several such panels on one surface, all panel joints have at least one swellable sealing lip. It can thereby be achieved that all panel joints and in particular also the points at which two joints, or three panels, meet, are protected against the penetration and penetration of liquids.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass alle Halteprofile eine quellbare Dichtlippe aufweisen.In a further embodiment of the invention, it can be provided that all holding profiles have a swellable sealing lip.
Dadurch kann vorteilhafterweise erreicht werden, dass nach der Verlegung mehrerer derartiger Paneele auf einer Fläche, alle Paneelfugen zwei quellbare Dichtlippe aufweisen. Dadurch kann erreicht werden, dass alle Paneelfugen und insbesondere auch die Punkte an denen zwei Fugen, beziehungsweise drei Paneele, aufeinandertreffen besonders gut gegen Eindringen und Durchdringen von Flüssigkeiten geschützt sind.This advantageously means that after laying several such panels on one surface, all panel joints have two swellable sealing lips. It can thereby be achieved that all panel joints and in particular also the points at which two joints or three panels meet, are particularly well protected against the penetration and penetration of liquids.
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe an dem Halteprofil stoffschlüssig, kraftschlüssig oder formschlüssig befestigt ist.In a further embodiment of the invention, it can be provided that the swellable sealing lip is attached to the holding profile in a material, non-positive or positive manner.
Dadurch kann erreicht werden, dass sich die Dichtlippe vor dem Verlegen nicht ungewollt von dem Paneel trennt. Beispielsweise kann erreicht werden, dass sich die Dichtlippe beim Transport, beim Lagern oder beim Schneiden der Paneele nicht ungewollt von dem Paneel löst.It can thereby be achieved that the sealing lip does not inadvertently separate from the panel before laying. For example, it can be achieved that the sealing lip does not unintentionally detach from the panel during transport, storage or cutting of the panels.
Durch eine stoffschlüssige Verbindung kann insbesondere ermöglicht werden, dass die quellbare Dichtlippe an einer beliebigen Stelle an dem Halteprofil angebracht werden kann. Dadurch ist vorteilhafter weise auch die Anbringung einer quellbaren Dichtlippe an filigranen Stellen des Halteprofils möglich. Für eine stoffschlüssige Verbindung kann dabei ein Kleber vorgesehen sein. Dadurch kann erreicht werden, dass auch eine pulverförmige Dichtlippe an dem Halteprofil angebracht werden kann.A cohesive connection can in particular make it possible for the swellable sealing lip to be attached to the holding profile at any point. This advantageously also allows the attachment of a swellable sealing lip at filigree points on the holding profile. An adhesive can be provided for a material connection. It can thereby be achieved that a powdery sealing lip can also be attached to the holding profile.
Durch eine kraftschlüssige und/oder formschlüssige Verbindung kann erreicht werden, dass eine Dichtlippe mit einem besonders großflächigen Querschnitt an dem Halteprofil angebracht werden kann. Dadurch kann eine besonders große absolute Volumenänderung beim Quellen der Dichtlippe erreicht werden. Dafür kann beispielsweise eine Nut vorgesehen sein, in welche eine Dichtlippe hineingepresst werden kann.By means of a non-positive and / or positive connection, it can be achieved that a sealing lip with a particularly large cross-section can be attached to the holding profile. A particularly large absolute change in volume when the sealing lip swells can thereby be achieved. For this purpose, for example, a groove can be provided, into which a sealing lip can be pressed.
In einer Ausgestaltung der Erfindung kann weiterhin vorgesehen sein, dass die quellbare Dichtlippe im Wesentlichen bündig mit dem Halteprofil abschließt.In one embodiment of the invention it can further be provided that the swellable sealing lip is essentially flush with the holding profile.
Dadurch kann erreicht werden, dass keine zusätzlichen Spannungen auf die Verbindung von aneinandergefügten Halteprofilen wirken.It can thereby be achieved that no additional stresses act on the connection of the holding profiles joined together.
In einer Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe derartig im Halteprofil der Paneelkante angeordnet ist, dass die quellbare Dichtlippe nachIn one embodiment of the invention it can be provided that the swellable sealing lip is arranged in the holding profile of the panel edge in such a way that the swellable sealing lip follows
Anbringung eines weiteren Paneels mit komplementärem Halteprofil, zum komplementären Halteprofil des weiteren Paneels eine Spielpassung oder Übergangspassung aufweist.Attaching a further panel with a complementary holding profile, has a clearance fit or transition fit to the complementary holding profile of the further panel.
Dadurch kann ebenfalls erreicht werden, dass keine zusätzlichen Spannungen auf die Verbindung von aneinandergefügten Halteprofilen wirken.This can also ensure that no additional stresses act on the connection of holding profiles joined together.
In einer Ausgestaltung der Erfindung kann vorgesehen sein, dass die quellbare Dichtlippe derartig im Halteprofils der Paneelkante angeordnet ist, dass die quellbare Dichtlippe nach Anbringung eines weiteren Paneels mit komplementärem Halteprofil, nach einem Quellen, in hydraulisch abdichtender Form an dem komplementären Halteprofil des weiteren Paneels anliegt.In one embodiment of the invention, it can be provided that the swellable sealing lip is arranged in the holding profile of the panel edge in such a way that the swellable sealing lip, after attachment of a further panel with a complementary holding profile, after swelling, rests in a hydraulically sealing form on the complementary holding profile of the further panel .
Dadurch kann erreicht werden, dass bei Bedarf, also wenn eine Flüssigkeit mit der Fuge in Kontakt kommt, durch das Quellen der Dichtlippe die Paneelfuge abgedichtet wird, ohne dass zuvor zusätzliche Spannungen auf die Verbindung von aneinandergefügten Halteprofilen wirken.This means that if necessary, i.e. if a liquid comes into contact with the joint, the panel joint is sealed by swelling of the sealing lip, without additional tension acting on the connection of the holding profiles that have been joined together.
Mit der Erfindung wird ferner eine Anordnung von mindestens zwei Paneelen mit quellbarer Dichtlippe vorgeschlagen.The invention also proposes an arrangement of at least two panels with a swellable sealing lip.
Im Detail ist eine Anordnung von mindestens zwei erfindungsgemäßen Paneelen vorgesehen. Dabei weisen die Paneele an einander zugewandten Paneelkanten komplementäre Halteprofile auf und sind durch die komplementären Halteprofile aneinander befestigt.In detail, an arrangement of at least two panels according to the invention is provided. The panels have complementary holding profiles on facing panel edges and are attached to one another by the complementary holding profiles.
Die Anordnung ist dabei dadurch gekennzeichnet, dass mindestens eines der aneinander zugewandten komplementären Halteprofile entlang der Längsachse eine quellbare Dichtlippe aufweist, und die quellbare Dichtlippe zum komplementären Halteprofil der anderen Paneelkante eine Spielpassung oder Übergangspassung aufweist, wobei die quellbare Dichtlippe nach Absorption einer wässrigen Flüssigkeit, in hydraulisch abdichtender Form an dem komplementären Halteprofil der anderen Paneelkante anliegt.The arrangement is characterized in that at least one of the mutually facing complementary holding profiles has a swellable sealing lip along the longitudinal axis, and the swellable sealing lip has a clearance fit or transition fit to the complementary holding profile of the other panel edge, the swellable Sealing lip after absorption of an aqueous liquid, in a hydraulically sealing form against the complementary holding profile of the other panel edge.
Durch diese Anordnung kann insbesondere erreicht werden, dass jede Paneelfuge eine quellbare Dichtlippe aufweist und es kann erreicht werden, dass bei Bedarf, also wenn eine Flüssigkeit mit der Fuge in Kontakt kommt, durch das Quellen der Dichtlippe die Paneelfuge abgedichtet wird, ohne dass zuvor zusätzliche Spannungen auf die Verbindung von aneinandergefügten Halteprofilen wirken.With this arrangement it can be achieved in particular that each panel joint has a swellable sealing lip and it can be achieved that if necessary, that is when a liquid comes into contact with the joint, the panel joint is sealed by the swelling of the sealing lip without any additional Tensions act on the connection of joined holding profiles.
Mit der Erfindung wird zudem ein Verfahren zur Herstellung eines Paneels mit quellbar Dichtlippe vorgeschlagen.The invention also proposes a method for producing a panel with a swellable sealing lip.
Im Detail ist vorgesehen, dass das Verfahren die Schritte aufweist:
- Bereitstellen eines Trägers,
- Ausformen von einem Halteprofil an zumindest einer Kante des Trägers,
- Anbringen einer quellbaren Dichtlippe an das Halteprofil
- Providing a carrier,
- Forming a holding profile on at least one edge of the carrier,
- Attach a swellable sealing lip to the holding profile
Dadurch kann vorteilhafterweise erreicht werden, dass bei der Ausformung des Halteprofils bereits eine Stelle zum Anbringen der quellbaren Dichtlippe vorgesehen werden kann. Zudem kann dadurch auch die quellbare Dichtlippe an das Halteprofil angepasst werden. Die quellbare Dichtlippe kann dabei vor oder nach dem Aufbringen von einer Dekorschicht und einer Deckschicht sowie gegebenenfalls weiterer Schichten, beispielsweise einer zwischen Dekor- und Deckschicht angeordneten Verschleißschicht, aufgebracht werden. Der Träger kann dabei aus einem für Paneele üblichen Material gefertigt sein.As a result, it can advantageously be achieved that a position for attaching the swellable sealing lip can already be provided when the holding profile is formed. In addition, the swellable sealing lip can also be adapted to the holding profile. The swellable sealing lip can be applied before or after the application of a decorative layer and a cover layer and, if appropriate, further layers, for example a wear layer arranged between the decorative and cover layer. The carrier can be made of a material that is customary for panels.
Mit der Erfindung wird weiterhin vorgeschlagen, ein quellbares Material zum Abdichten von Paneelen zu verwenden.The invention further proposes to use a swellable material for sealing panels.
Im Detail ist vorgesehen, dass ein quellbares Material zum Abdichten von vorbeschriebenen Paneelen verwendet wird.It is envisaged in detail that a swellable material is used to seal the panels described above.
Durch die Verwendung eines quellbaren Materials kann vorteilhafterweise erreicht werden, dass die Paneelfugen nur bei Bedarf, also wenn eine Flüssigkeit mit der Fuge in Kontakt kommt, durch das Quellen des Materials abgedichtet wird, ohne dass zuvor zusätzliche Spannungen auf die Verbindung von aneinandergefügten Halteprofilen wirken.By using a swellable material, it can advantageously be achieved that the panel joints are sealed by swelling of the material only when needed, i.e. when a liquid comes into contact with the joint, without additional stresses first acting on the connection of the holding profiles joined together.
Die Erfindung ist nachfolgend anhand der Figuren weiter erläutert. Die Figuren zeigen mögliche Ausgestaltungen der Erfindung.
