Abstract

The floor covering has a usable layer which is produced by needlefelt technology and is needle-punched with a batt. A heavy-duty backing of electrically conductive plastic is applied to the surface opposite the usable layer. The electrostatic charge on the surface can be conducted to the bottom surface by an electrically conductive batt which on the one hand is applied with the heavy-duty backing and on the other hand is self-adhesive on the downward-facing surface.

Beschreibung description

Die Erfindung betrifft ein elektrisch ableitfähiges textiles Bodenbelagmaterial gemäss dem Oberbegriff des Anspruches 1. The invention relates to an electrically conductive textile floor covering material according to the preamble of claim 1.

Aus der CH-Patentschrift Nr. 526 940 ist ein textiles Bodenbelagmaterial bekannt, das aus einer oberen Vliesschicht aus trittfesten synthetischen Fasern und einer elektrisch leitfähig ausgerüsteten zweiten Vliesschicht besteht, die so vernadelt ist, dass die aus dem ersten Vlies gebildete Nutzschicht nicht elektrisch leitfähig ist. From CH Patent No. 526 940 a textile floor covering material is known which consists of an upper non-woven layer made of hard-wearing synthetic fibers and an electrically conductive second non-woven layer which is needled in such a way that the wear layer formed from the first non-woven is not electrically conductive .

In der CH-Patentschrift Nr. 529 542 ist ein antistatisch ausgerüsteter Florteppich beschrieben, der aus einem Grundgewebe, einer Begehfaserschicht mit einer höchstens an das Grundgewebe angrenzenden Schicht aus antistatischem Material und einer Rückenschicht aus einem polymeren Material besteht. CH Patent No. 529 542 describes an antistatically finished pile carpet which consists of a base fabric, a walk fiber layer with a layer of antistatic material which at most adjoins the base fabric and a back layer made of a polymeric material.

Der dem genannten Stand der Technik anhaftende Nachteil besteht darin, dass eine auf der Oberseite vorhandene elektrische Aufladung nicht vollständig zur Unterseite abgeleitet wird. The disadvantage inherent in the prior art is that an electrical charge on the top is not completely discharged to the bottom.

Ziel der Erfindung ist es, ein elektrisch ableitfähiges, textiles Bodenbelagmaterial zu schaffen, bei dem dieser Nachteil nicht auftritt. The aim of the invention is to provide an electrically conductive, textile flooring material in which this disadvantage does not occur.

Dieses Ziel wird erfindungsgemäss mit den kennzeichnenden Merkmalen des Patentanspruches 1 erreicht. This aim is achieved according to the invention with the characterizing features of patent claim 1.

Um einerseits eine Schallisolation zu bewirken und andererseits das Gewicht pro Flächeneinheit nicht zu hoch werden zu lassen, ist ein nach Nadelfilztechnologie hergestelltes Faservlies das elektrisch leitfähig ist, auf die Schicht kaschiert. Der Vorteil besteht darin, dass das Bodenbelagmaterial bahnenmässig verlegt werden kann. In order on the one hand to provide sound insulation and on the other hand not to make the weight per unit area too high, a nonwoven fabric made using needle felting technology that is electrically conductive is laminated onto the layer. The advantage is that the flooring material can be laid as a membrane.

Bei einem bevorzugten Ausführungsbeispiel der Erfindung ist eine eine elektrisch leitfähige Kunststoffschicht bildende Schwerbeschichtung auf der der Trittschicht abgewandten Fläche der Basisschicht aufgebracht, die Schicht ist aus einem nach der Nadelfilztechnologie hergestelltes Faservlies, das elektrisch leitfähig ist, und das Bodenbelagmaterial ist plattenförmig. In a preferred embodiment of the invention, a heavy-duty coating forming an electrically conductive plastic layer is applied to the surface of the base layer facing away from the wear layer, the layer is made of a non-woven fabric made according to needle felting technology, which is electrically conductive, and the flooring material is plate-shaped.

Die Vorteile des bevorzugten Ausführungsbeispiels sind im wesentlichen darin zu sehen, dass das Bodenbelagmaterial auf der Oberseite auftretende elektrische Aufladung zur Unterseite ableiten kann, wegen der als Faservlies ausgebildeten selbsthaftenden Schicht eine Schallisolation bewirkt und eine rutschhemmende Wirkung erzielt wird, eine massstabile Platte vorliegt, die einfach verlegbar ist, und bis zu 2 mm dicke Flachkabel unter der Platte verlegt werden können. The advantages of the preferred exemplary embodiment are essentially to be seen in the fact that the floor covering material can dissipate electrical charges occurring on the upper side, that due to the self-adhesive layer formed as a non-woven fabric causes sound insulation and a non-slip effect, a dimensionally stable plate that is simple is present can be laid, and flat cables up to 2 mm thick can be laid under the plate.

Am folgenden Beispiel wird die vorliegende Erfindung erläutert. The present invention is illustrated by the following example.

Das Bodenbelagmaterial enthält ein vorgenadel-tes Vlies aus synthetischen Fasern und einem Anteil elektrisch leitfähigen synthetischen Fasern, die gleichmässig über die Fläche verteilt eingenadelt sind. Dieses Vlies wird zusammen mit einem Endlosfaservlies so vernadelt, dass ein bahnenförmiges Material mit einer Nutzschicht und einer Basisschicht entsteht. The flooring material contains a pre-needled fleece made of synthetic fibers and a portion of electrically conductive synthetic fibers, which are needled evenly over the surface. This fleece is needled together with an endless fiber fleece in such a way that a web-shaped material with a wear layer and a base layer is produced.

Auf die der Nutzschicht abgewandten Seite der On the side facing away from the wear layer

Basisschicht wird eine Schwerbeschichtung aus elektrisch leitfähigem Kunststoff aufgebracht. Durch diese Schwerbeschichtung ist ein Vorstanzen erforderlich. Auf der nach unten gerichteten Fläche der Schwerbeschichtung wird ein nach der Nadelfilztechnologie hergestelltes Faservlies vorgesehen, das durch gleichmässig verteilte elektrisch leitende Fasern elektrisch leitfähig gemacht und das auf der nach unten gerichteten Seite durch geeignete Mittel eine selbsthaftende Wirkung versehen wird. Dieses Faservlies wird durch eine Folie abgedeckt, um eine Reduktion der selbsthaftenden Wirkung durch Verschmutzung zu verhindern. Schlussendlich werden durch einen Stanzvorgang Platten hergestellt. A heavy coating made of electrically conductive plastic is applied to the base layer. Due to this heavy coating, pre-punching is required. On the downward-facing surface of the heavy coating, a nonwoven fabric made according to the needle felt technology is provided, which is made electrically conductive by uniformly distributed electrically conductive fibers and which is provided with a self-adhesive effect on the downward-facing side by suitable means. This fiber fleece is covered with a film to prevent a reduction in the self-adhesive effect due to contamination. Finally, plates are produced by a punching process.

Diese Platten haben aufgrund der Schwerbeschichtung und der selbsthaftenden Wirkung des elektrisch leitfähigen Faservlieses sehr gute Selbstliegeeigenschaften und eignen sich insbesondere zur Verlegung in Rechenzentren. Due to the heavy coating and the self-adhesive effect of the electrically conductive fiber fleece, these panels have very good self-supporting properties and are particularly suitable for laying in data centers.
