Description
Die Erfindung betrifft ein Bodenpaneel mit einem Kern, einer auf die Oberseite des Kerns aufgebrachten Deckschicht und einem auf die Unterseite des Kerns aufgebrachten Gegenzug und ein Verfahren zu seiner Herstellung.The invention relates to a floor panel having a core, a top layer applied to the top of the core and a backing applied to the underside of the core and a method for its production.
Ein solches Bodenpaneel ist beispielsweise aus der
Die Vorteile einer Deckschicht aus Vinyl gegenüber einem Laminatboden mit einer Kunstharzdeckschicht bestehen in der deutlich geringeren Geräuschentwicklung beim Begehen (Trittschall) und der weicheren und damit angenehmeren Oberfläche. Eine Holzwerkstoffplatte (HDF, MDF) als Trägerplatte ist nicht geeignet, für Paneele eingesetzt zu werden, die in Bereichen mit erhöhter Luftfeuchte oder gar mit direkter Wassereinwirkung eingesetzt werden. Damit sind für den vorgenannten Bodenbelag, ebenso wie für die Standardlaminatböden auch, bestimmte Anwendungsbereiche ausgeschlossen.The advantages of a cover layer of vinyl compared to a laminate floor with a synthetic resin topcoat consist in the significantly lower noise during walking (impact sound) and the softer and thus more pleasant surface. A wood-based panel (HDF, MDF) as a support plate is not suitable for use in panels that are used in areas with high humidity or even direct water exposure. Thus, certain applications are excluded for the aforementioned flooring, as well as for the standard laminate floors.
Zur Lösung dieses Problems wurde ein Bodenbelag auf Basis von reinem Vinyl entwickelt. Aus Kostengründen sind derartige Vinylböden ohne Trägerplatten nur ca. 5 mm dick, was eine Reihe von Nachteilen mit sich bringt. Wenn Vinylpaneele leimlos miteinander verbunden werden sollen, muss das dafür vorgesehene Profil (Klick-Profil) in ein nur 5 mm starkes Produkt eingebracht werden, womit die Auswahl des Profils stark eingeschränkt ist. Da es sich bei Vinyl um einen thermoplastischen Kunststoff handelt, muss auch dem Kriechverhalten des Materials bei erhöhten Temperaturen Rechnung getragen werden. Thermoplasten erweichen und verlieren damit langsam ihre Festigkeit. Damit besteht die Gefahr, dass sich die Profile öffnen können, was zu Spaltenbildung an der Verbindungsstelle führt, die sichtbar ist und einen minderwertigen Qualitätseindruck beim Betrachter hinterlässt. Dies gilt insbesondere in Räumen mit Fußbodenheizungen oder in Ländern mit höheren Temperaturen in bestimmten Jahreszeiten. Ein weiterer Nachteil besteht darin, dass durch die geringe Stärke des Paneels in Kombination mit den thermoplastischen Eigenschaften seines Materials Unebenheiten im Untergrund leicht durch den Bodenbelag hindurchtreten können. Mit der Beseitigung der Feuchtigkeitsempfindlichkeit solcher Paneele müssen dann andere Nachteile des Produkts in Kauf genommen werden.To solve this problem, a floor covering based on pure vinyl was developed. For cost reasons, such vinyl floors without support plates are only about 5 mm thick, which brings a number of disadvantages. If vinyl panels are to be bonded together without glue, the profile provided for this purpose (click profile) must be inserted in a product only 5 mm thick, which considerably limits the selection of the profile. Since vinyl is a thermoplastic, the creep behavior of the material at elevated temperatures must also be taken into account. Thermoplastics soften and slowly lose their strength. There is thus the danger that the profiles may open, which leads to the formation of gaps at the connection point, which is visible and leaves an inferior quality impression on the viewer. This is especially true in rooms with underfloor heating or in countries with higher temperatures in certain seasons. Another disadvantage is that due to the small thickness of the panel in combination with the thermoplastic properties of its material, unevenness in the ground can easily pass through the floor covering. With the removal of the moisture sensitivity of such panels then other disadvantages of the product must be accepted.
Von dieser Problemstellung ausgehend, sollen Bodenpaneele zur Verfügung gestellt werden, die feuchtigkeitsunempfindlich sind, zum leimlosen Verlegen in ihrer Verbindungstechnik (Kantenprofilierung) ohne Einschränkungen auf bewährte Profile zurückgreifen können und die Vorteile von Vinylpaneelen beim Begehen bieten.Starting from this problem, floor panels are to be made available that are insensitive to moisture, for glueless laying in their connection technique (edge profiling) without restrictions on proven profiles and can provide the benefits of vinyl panels when walking.
Zur Problemlösung zeichnet sich ein gattungsgemäßes Bodenpaneel dadurch aus, dass der Kern mehrschichtig aufgebaut ist und mindestens eine erste Schicht bestehend aus einer Mischung aus Magnesiumoxid und Magnesiumchlorid mit Zuschlagstoffen aufweist, an die sich beidseitig je mindestens eine Schicht aus einem Glasfasergewebe anschließt, und die Deckschicht aus Polyvinylchlorid besteht.To solve the problem, a generic floor panel is characterized by the fact that the core is multi-layered and has at least a first layer consisting of a mixture of magnesium oxide and magnesium chloride with aggregates, on each side at least one layer of a glass fiber fabric connects, and the cover layer Polyvinyl chloride exists.
Eine Trägerplatte auf Basis von Magnesiumsalzen ist feuchtigkeitsfest. Dieses Material ist unter der Bezeichnung Sorelzement bekannt und wird herkömmlich als Estrich beim Hausbau eingesetzt. Es ist auch bekannt, Sorelzement für die Herstellung von Industriefußböden und von Schleif- und Poliersteinen für die Marmorindustrie zu verwenden. Zu seinen Vorteilen zählen die sehr schnelle Festigkeitsentwicklung und die hohe Endfestigkeit. Im Wohnungsbau wurden solchen Estriche in der Nachkriegszeit als „Steinholz“ bekannt. Zusätzlich zu dem Magnesiumchlorid und dem Magnesiumoxid enthielten diese Beläge erhebliche Mengen an Holzmehl als Füllstoff. Steinholzfußböden sind fußwarm und angenehm zu begehen. Sie besitzen auch eine gewisse Eigenelastizität. Im Vergleich zu einer Holzwerkstoffplatte quillt dieses Material aber nicht auf. Durch die beiden Schichten aus Glasfasergewebe wird der Kern stabilisiert, sodass er neben der Feuchtigkeitsunempfindlichkeit auch hohe Festigkeitseigenschaften besitzt. Gleichzeitig ist eine Profilierung der Seitenkanten in derselben Art und Weise möglich, wie bei einer Trägerplatte aus HDF oder MDF. Trotz der Glasfasergewebelagen liegt der Preis dieses Trägerwerkstoffes auf dem Niveau von Holzwerkstoffplatten gleicher Stärke, was seine Ursache in der nahezu uneingeschränkten zur Verfügung stehenden Rohstoffbasis hat. Magnesium ist eines der häufigsten Elemente in der Erdkruste. In großen Lagerstätten liegen die benötigten Salze teilweise schon in der benötigten Reinheit vor. Vorteilhaft ist weiterhin, dass das Trägermaterial nach der Nutzung auch problemlos recycelt werden kann. Die Deckschicht kann großflächig oder als einzelne Vinylpads auf den Kern aufgeklebt werden. Auch der Gegenzug wird auf die Unterseite des Kernes aufgeklebt, wobei als Klebstoffe PU, Epoxid usw. eingesetzt werden sollten, die eine hohe Wasserbeständigkeit besitzen.A support plate based on magnesium salts is moisture resistant. This material is known as Sorelzement and is commonly used as screed in house building. It is also known to use corrosive cement for the manufacture of industrial flooring and of sanding and polishing stones for the marble industry. Its advantages include the very fast strength development and the high final strength. In residential construction, such screeds were known in the post-war period as "stone wood". In addition to the magnesium chloride and magnesium oxide, these coatings contained significant amounts of wood flour as a filler. Stone wood floors are warm and pleasant to walk on. They also have a certain inherent elasticity. Compared to a wood-based panel, this material does not swell up. Through the two layers of glass fiber fabric, the core is stabilized, so that he also has high strength properties in addition to the insensitivity to moisture. At the same time a profiling of the side edges in the same manner is possible, as in a carrier plate made of HDF or MDF. Despite the glass fiber fabric layers, the price of this carrier material is at the level of wood-based panels of the same thickness, which has its cause in the almost unlimited available raw material base. Magnesium is one of the most common elements in the earth's crust. In large deposits, the required salts are sometimes already present in the required purity. A further advantage is that the carrier material can be easily recycled after use. The cover layer can be adhered to the core over a large area or as individual vinyl pads. Also, the counter-pull is glued to the underside of the core, being used as adhesives PU, epoxy etc. should be used, which have a high water resistance.
Vorzugsweise ist vorgesehen, dass der Kern eine zweite Schicht aufweist, die aus einer Mischung aus Magnesiumoxid und Magnesiumchlorid mit Zuschlagstoffen besteht. Wenn sich beidseitig auch an die zweite Schicht eine Schicht aus einem Glasfasergewebe anschließt, wird die Festigkeit und Stabilität des Kernes weiter erhöht.It is preferably provided that the core has a second layer, which consists of a mixture of magnesium oxide and magnesium chloride with additives. If a layer of a glass fiber fabric also connects to the second layer on both sides, the strength and stability of the core is further increased.
Wenn an die beiden äußeren Schichten aus Glasfasergewebe je eine nicht gewebte Vliesschicht angrenzt, verbessern sich die Stabilitätseigenschaften des Kernes weiter. Außerdem haben die Vliesschichten den Vorteil, dass sie bei der Plattenherstellung als Trennschichten dienen können, und dadurch verhindert wird, dass sich der Säure-Base-Zement mit den zur Formung der Platte notwendigen Formplatten verbindet.If a nonwoven nonwoven layer adjoins the two outer layers of glass fiber fabric, the stability properties of the core continue to improve. In addition, the nonwoven layers have the advantage that they can serve as release layers in the plate production, and thereby prevents the acid-base cement with the mold plates necessary for forming the plate connects.
Vorzugsweise bestehen die Zuschlagstoffe zumindest teilweise aus Lignozellulose, insbesondere aus Holzmehl, Holzfasern und/oder Holzspänen.Preferably, the additives are at least partially made of lignocellulose, in particular of wood flour, wood fibers and / or wood shavings.
Die Trittschalleigenschaften des Bodenpaneels werden weiter verbessert, wenn der Gegenzug aus Kork besteht. Der Gegenzug kann aber auch aus einer Kunststofffolie oder aus Papier bestehen.The impact sound properties of the floor panel will be further improved if the return is made of cork. The return can also consist of a plastic film or paper.
Um mehrere Paneele leimlos miteinander verbinden zu können, sind an den Seitenkanten Verbindungsmittel mit darin integrierten Verriegelungsmitteln angebracht, wie sie bei den als Klickpaneele bekannten Laminatpaneelen in vielfältiger Form realisiert werden können.In order to be able to connect a plurality of panels without glue, connecting means with locking means integrated therein are attached to the side edges, as can be realized in a variety of forms in the laminate panels known as click panels.
Insgesamt wird ein Produkt erzielt, das im Hinblick auf die Entstehung von Tritt- und Raumschall optimiert ist. Neben dem thermoplastischen Polyvinylchlorid als Deckschicht ist dafür auch das Kernmaterial mit einer gegenüber Holzwerkstoffen erhöhten Rohdichte von 1100 kg/m3 bis 1400 kg/m3 verantwortlich, und durch die Verwendung von elastischen Klebern und dem Gegenzug aus Kork werden diese Eigenschaften weiter optimiert.Overall, a product is achieved, which is optimized in terms of the formation of footstep and room sound. In addition to the thermoplastic polyvinyl chloride as a top layer, the core material is also responsible for this with a raw density of 1100 kg / m 3 to 1400 kg / m 3 compared with wood-based materials, and these properties are further optimized by the use of elastic adhesives and the cork backing.

Die Vliesschichten
Die Mischung aus Magnesiumchlorid und Magnesiumoxid ist auch unter der Bezeichnung Sorelbeton bekannt. Ein Säure-Base-Zement, der von Stanislaw Sorel entwickelt wurde. Als Säure fungiert eine wässrige Magnesiumchloridlösung, als Base kaustisch gebrannter Magnetisit. Je nach Reaktivität des verwendeten Magnesiumoxids kommt es innerhalb von Minuten oder aber auch erst nach Stunden zu einem Härten des Gemisches. Die Zeit, die zum Aushärten benötigt wird, ist somit einstellbar.The mixture of magnesium chloride and magnesium oxide is also known as Sorelbeton. An acid-base cement developed by Stanislaw Sorel. The acid used is an aqueous magnesium chloride solution, caustic calcined magnetisite as the base. Depending on the reactivity of the magnesium oxide used, hardening of the mixture takes place within minutes or else only after hours. The time required for curing is thus adjustable.
Zunächst wird der Kern
Nach dem Kalibrieren wird der Aufbau in einen Trockenofen gebracht, wo er trocknet und aushärtet (Kristallisierung der Magnesiumsalze). Dabei bleibt die Abdeckplatte mit dem Aufbau verbunden, damit sich die Oberseite nicht verwirft.After calibration, the assembly is placed in a drying oven where it dries and hardens (crystallization of magnesium salts). The cover remains connected to the structure so that the top does not discard.
Nach dem Trocknen wird die Vinylschicht
