Description

Die Erfindung betrifft eine Schalldämmatte gemäss dem Oberbegriff des Anspruchs 1 sowie einen Bodenbelag mit Schalldämmatte gemäss Anspruch 8.The invention relates to a sound insulation mat according to the preamble of claim 1 and a floor covering with soundproofing mat according to claim 8.

Wenn nachfolgend verallgemeinernd von Laminatböden gesprochen wird, so sind darunter Bodenbeläge zu verstehen, die aus hochverdichteten Spanplatten hergestellt sind und zumindest auf der Oberseite eine Beschichtung und/oder ein Furnier aufweisen. Die Höhe solcher Laminatböden beträgt im allgemeinen zwischen 6 und 8 mm. Neben vielen Vorteilen weisen solche Laminatböden den Nachteil auf, dass beim Begehen laute Gehgeräusche entstehen. Dies wirkt sich insbesondere in grossen und stark frequentierten Räumen sehr negativ aus.If in the following spoken generally of laminate floors floor coverings that are made of high density Chipboard are made and at least on the Have a coating and / or a veneer on the top. The The height of such laminate floors is generally between 6 and 8 mm. In addition to many advantages, such laminate floors have the Disadvantage that loud walking noises arise when walking. This particularly affects large and heavily frequented areas Clear out very negatively.

Die Ursachen dafür lassen sich vereinfacht ausgedrückt folgendermassen erklären:The causes of this can be put simply as follows to explain:

Laminatbodenelemente sind leicht und wegen ihres verdichteten Aufbaus sehr steif und hart. Bei direkter Schritt-Anregung, speziell mit harten Absätzen, erzeugen sie im jeweiligen Raum - Senderaum- einen hohen, durch die Luft übertragenen Schallpegel, dessen Frequenz in einem subjektiv als äusserst unangenehm empfundenen Bereich liegt.Laminate flooring elements are light and compact because of them Structure very stiff and hard. With direct step stimulation, especially with hard heels, they create in the respective room - Broadcast room - a high sound level transmitted through the air, its frequency in a subjectively extremely uncomfortable perceived area.

Auch die Verwendung von Unterlagen wie beispielsweise Kork, Filz und dergleichen bringt keine nennenswerte Verbesserung, da solche Unterlagen zwar die Schallübertragung zwischen Bodenbelag und Boden dämpfen, den Schallpegel -Luftschallübertragungim eigentlichen Senderaum jedoch kaum heruntersetzen.The use of documents such as cork, Felt and the like bring no significant improvement because such documents do the sound transmission between flooring and floor dampen, the sound level airborne sound transmission but hardly reduce the actual broadcasting room.

Es ist daher die Aufgabe der Erfindung, eine Schalldämmatte für steife Bodenbeläge vorzuschlagen, mittels welcher die Schallabstrahlung im Senderaum massgeblich vermindert werden kann. It is therefore the object of the invention to provide a sound insulation mat for propose stiff flooring, by means of which the sound radiation can be significantly reduced in the broadcasting room.

Diese Aufgabe wird durch eine Schalldämmatte gelöst, welche die im Anspruch 1 in Kombination aufgeführten Merkmale aufweist und flächig mit der Unterseite des Bodenbelags verbunden ist.This task is solved by a sound insulation mat, which the features in combination in claim 1 and is connected to the underside of the floor covering.

Versuche mit einer Schalldämmatte, die aus einem flexiblen, thermoplastischen Kunststoff mit viskoelastischem Verhalten gefertigt und vollflächig mit dem Laminatboden verklebt ist und eine Höhe von 2.lmm und ein Dichte von 2.4g/m3 aufweist, haben eine Schallpegelreduktion im Senderaum von 3dB(A) bewirkt.Experiments with a sound insulation mat, which is made of a flexible, thermoplastic material with viscoelastic behavior and is fully glued to the laminate floor and has a height of 2.lmm and a density of 2.4g / m 3 , have a noise level reduction in the transmission room of 3dB (A. ) causes.

Bevorzugte Ausführungen der Schalldämmatte sind in den abhängigen Ansprüchen 2 bis 7 umschrieben.Preferred versions of the sound insulation mat are in the dependent Claims 2 to 7 circumscribed.

Im Anspruch 8 wird zudem ein Bodenbelag unter Schutz gestellt, dessen Unterseite mit einer oder mehreren Schalldämmatte(n) gemäss einem der Ansprüche 1 bis 7 versehen ist.Claim 8 also places a floor covering under protection, whose underside with one or more sound insulation mat (s) according one of claims 1 to 7 is provided.

Bevorzugte Ausführungsformen dieses Bodenbelags sind in den abhängigen Ansprüchen 9 bis 11 umschrieben.Preferred embodiments of this flooring are in the dependent Claims 9 to 11 circumscribed.

Anhand der Figur 1 soll nachfolgend ein bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert werden.A preferred embodiment is shown below with reference to FIG the invention will be explained in more detail.

Fig. 1 zeigt einen Querschnitt durch einen Laminatboden 2 der aus einer Vielzahl von mittels Nut 3 und Kamm 4 zusammengefügten Laminatbodenelementen 2A besteht. Auf der Unterseite jedes Laminatbodenelements 2A ist eine Schalldämmatte 1 vollflächig verklebt angebracht. Um die Schalldämmatten 1 einfach und schnell am jeweiligen Laminatbodenelement 2A anbringen zu können, sind diese einseitig mit einer Selbstklebeschicht versehen, welche mit einer abziehbaren Folie bedeckt ist. Vorzugsweise werden die Schalldämmatten 1 in Formaten gefertigt, die auf die Grössen der Laminatbodenelemente 2A abgestimmt sind, wobei die Schalldämmatten 1 sowohl in der Breite wie auch in der Länge vorzugsweise um einige Millimeter kürzer, bzw. schmaler als das jeweilige Laminatbodenelement 2A sind. Diese Gestaltung vereinfacht das Aufkleben, ohne dass dabei nennenswerte Nachteile bezüglich der Schalldämmung in Kauf genommen werden müssten.Fig. 1 shows a cross section through a laminate floor 2 from a variety of by means of groove 3 and 4 comb Laminate flooring elements 2A consists. On the bottom of each Laminate flooring element 2A is a sound insulation mat 1 over the entire surface glued attached. To the sound insulation mats 1 simple and to be able to quickly attach to the respective laminate floor element 2A, are self-adhesive on one side, which is covered with a peelable film. Preferably the sound insulation mats 1 are manufactured in formats that are matched to the sizes of the laminate flooring elements 2A, the sound insulation mats 1 both in width and in the length is preferably a few millimeters shorter or narrower than the respective laminate floor element 2A. This design simplifies the gluing without significant Disadvantages in terms of sound insulation accepted would have to be.

Die Schalldämmatte 1 ist aus einem flexiblen, thermoplastischen Kunststoff mit viskoelastischem Verhalten gefertigt, wobei unter viskoelastischem Verhalten ein Deformationsverhalten verstanden wird, bei dem sowohl eine zähplastische wie auch eine elastische Verformung beteiligt ist. Dieses Verhalten wird oft auch mit -innerer Dämpfung- umschrieben. Anstelle eines thermoplastischen Kunststoffes kann auch ein Naturstoff mit gleichartigem Deformationsverhalten, z.B. modifiziertes Bitumen, verwendet werden. Die Dichte der Schalldämmatte 1 sollte zumindest 2g/cm3 betragen. Durch das relativ hohe, spezifische Gewicht braucht die Schalldämmatte 1 nicht sehr hoch zu sein. In der Regel genügt eine Höhe von ca. 2 mm, um eine Schallpegelreduktion im Senderaum in der Grössenordnung von 3dB(A) zu erreichen. Dies ist insofern wichtig, als dass die Gesamthöhe des Bodenbelags -Laminatbodenelement 2A plus Schalldämmatte 1- in der Regel 10mm nicht überschreiten sollte.The sound insulation mat 1 is made of a flexible, thermoplastic material with viscoelastic behavior, wherein viscoelastic behavior is understood to mean a deformation behavior in which both a tough plastic and an elastic deformation is involved. This behavior is often described with internal damping. Instead of a thermoplastic, a natural material with the same deformation behavior, eg modified bitumen, can also be used. The density of the sound insulation mat 1 should be at least 2 g / cm 3 . Due to the relatively high, specific weight, the sound insulation mat 1 need not be very high. As a rule, a height of approx. 2 mm is sufficient to achieve a sound level reduction in the transmission room in the order of 3dB (A). This is important insofar as the total height of the floor covering laminate floor element 2A plus sound insulation mat 1 should generally not exceed 10 mm.

Die Schalldämmatte ist aus einem EVA-Kunststoff - Ethylen/Vinylacetat-Copolymer- gefertigt. Als Grundmischung sind 10 bis 40 Gewichtsprozent eines Ethylen/Vinylacetat-Mischpolymeres vorgesehen, wobei der Vinylacetatanteil 10 bis 45 Gewichtsprozent der Grundmischung ausmacht. Vorzugsweise enthält die Grundmischung zudem zwischen 60 und 90 Gewichtsprozent Füllstoffe mit einer Dichte von zumindest 2,5g/cm3.The sound insulation mat is made of an EVA plastic - ethylene / vinyl acetate copolymer. 10 to 40 percent by weight of an ethylene / vinyl acetate copolymer is provided as the base mixture, the vinyl acetate portion accounting for 10 to 45 percent by weight of the base mixture. The basic mixture preferably also contains between 60 and 90 percent by weight of fillers with a density of at least 2.5 g / cm 3 .

Die übrigen Daten der Schalldämmatte sehen wie folgt aus: Wärmeleitfähigkeit: > 0,3 W/mK Druckfestigkeit: ca. 30 N/cm2 Shore A-Härte: 80-90 Wasserdampfdiff.-Widerstandsfaktor µ: ca. 40'000 Brandkennziffer: 5,3 The other data of the sound insulation mat look as follows: Thermal conductivity: > 0.3 W / mK Compressive strength: approx. 30 N / cm 2 Shore A hardness: 80-90 Water vapor diff. Resistance factor µ: approx.40,000 Brand code: 5.3

Unter Laminatbodenelement wird im allgemeinen Sprachgebrauch ein aus hochverdichteten Spanplatten hergestelltes Element bezeichnet, das zumindest auf der Oberseite -Gehfläche- beschichtet und/oder mit einem Furnier versehen ist. Die Dicke derartiger Laminatbodenelemente beträgt im allgemeinen zwischen 6 und 8 mm. Da solche Laminatbodenelemente relativ leicht und dabei sehr hart sind, eignet sich die erfindungsgemässe Schalldämmatte 1 insbesondere zur Verwendung mit derartigen Bodenbelägen. Allerdings kann die beschriebene Schalldämmatte natürlich auch zusammen mit beliebig anderen, steifen Bodenbelägen eingesetzt werden.In general, laminate flooring is used refers to an element made from high-density chipboard, that is coated at least on the top surface and / or is provided with a veneer. The thickness of such Laminate flooring elements is generally between 6 and 8 mm. Because such laminate flooring elements are relatively light and at the same time are very hard, the soundproofing mat according to the invention is suitable 1 in particular for use with such floor coverings. However, the sound insulation mat described can of course also be used used together with any other stiff flooring will.

Anstelle von Schalldämmatten die nachträglich an die einzelnen Laminatbodenelemente angeklebt werden, ist es durchaus denkbar, dass derartige Schalldämmatten bei der Herstellung der Laminatbodenelemente in einem zusätzlichen Arbeitsgang direkt aufgebracht -verklebt- werden.Instead of sound insulation mats, they can be added to the individual Laminate floor elements are glued, it is quite conceivable that such sound insulation mats in the manufacture of the laminate floor elements applied directly in an additional step to be glued.
