Description

Flammenhemmendes elastiAches Bodenbelagselement Flame-retardant elastic flooring element
Die Erfindung betrifft ein elastisches Bodenbelagselement, insbesondere einThe invention relates to an elastic floor covering element, in particular a
Fallschutzelement, aufweisend ein Gummigranulat und ein Bindemittel. Fall protection element, comprising a rubber granulate and a binding agent.
Elastische Bodenbelagselemente werden für eine Vielzahl von Aufgaben eingesetzt, beispielsweise als Fallschutzbelag. Derartige Fallschutzelemente können elastische Rasengiter bzw. elastische Bodenbeläge ausbilden, wie sie beispielsweise in dem EPResilient floor covering elements are used for a variety of tasks, for example as fall protection covering. Such fall protection elements can form elastic lawn grids or elastic floor coverings, as they are, for example, in the EP
2 019 169 A bzw. dem EP 2 374932 A gezeigt werden. 2 019 169 A and EP 2 374932 A.
Eine weitere Anwendemöglichkeit ist die Verwendung eines elastischen Bodenbelagselements als Schallschutzelement, wie es beispielsweise von der EP 2 463451 A1 offenbart wird. Another possible application is the use of an elastic floor covering element as a soundproofing element, as disclosed, for example, by EP 2 463451 A1.
Derartige Bodenelemente sind aus brennbaren Stoffen zusammengesetzt. Sie können somit nicht in Bereichen eingesetzt werden, in den besondere Anforderungen an das Brandverhalten gestellt werden. Aus dem Stand der Technik sind Möglichkeiten bekannt, mit denen das Brandverhalten von Elastomeren durch Zugabe von Zusatzstoffen verändert werden kann. Such floor elements are composed of combustible materials. They can therefore not be used in areas in which special requirements are placed on fire behavior. Possibilities are known from the prior art with which the fire behavior of elastomers can be changed by adding additives.
Aus dem EP 2 203 515 B1 sind thermoplastische Elastomere bekannt, welche durch Zusatzstoffe flammhemmend wirken und so als Dichtung in Brandschutz-sensiblen Bereichen eingesetzt werden können. Der dort offenbarte halogenfreie thermoplastische Elastomer-Compound umfasst ein Styrol enthaltenes thermoplastisches Elastomer, ein Ammoniumspolyphosphat enthaltenes Flammschutzmittel, Weichmacher, ein sekundäres Polymer in Form von Polypropylen und expandierbaren Graphit. Thermoplastic elastomers are known from EP 2 203 515 B1, which have a flame-retardant effect due to additives and can thus be used as a seal in areas sensitive to fire protection. The halogen-free thermoplastic elastomer compound disclosed there comprises a styrene-containing thermoplastic elastomer, a flame retardant containing ammonium polyphosphate, plasticizers, a secondary polymer in the form of polypropylene and expandable graphite.
Das EP 2669 324 A1 zeigt die Herstellung von dämmschichtbildenden Bauartikeln für den vorbeugenden Brandschutz, wie z.B. Dichtungen oder Manschetten, auf Basis eines PP Elastomers. In das Matrixmaterial wird zusätzlich zu intumeszierenden Blähgraphit zumindest ein Treibmittel und ein Flammschutzmittel eingebettet. EP 2669 324 A1 shows the production of building articles that form an insulating layer for preventive fire protection, such as seals or sleeves, based on a PP elastomer. In addition to intumescent expandable graphite, at least one propellant and one flame retardant are embedded in the matrix material.
Aufgabe dieser Patentanmeldung ist es, ein flammenhemmendes Bodenbelagselement vorzuschlagen, welches einfach aufgebaut und mit nur wenigen Verfahrensschritten kostengünstig herstellbar ist. Diese Aufgabe wird durch das erfindungsgemäße Bodenbelagselement mit den Merkmalen des Anspruchs 1 gelöst. Ein wesentlicher Grundgedanke der Erfindung ist es, das Gummigranulat des bekannten elastischen Bodenbelagselements vor dem Binden einen Gewichts-Anteil an Blähgraphit bei zu mischen. Die intumesziernde Wirkung des Blähgraphits erschwert eine Wanderung einer Flammenfront. Sie reduziert den kritischen Wärmestrom und die Rauchentwicklung. Zudem verhindert sie ein Abtropfen bzw. Abfallen von brennenden Material. Diese Wirkung des Blähgraphits macht sich die Erfindung für die Bildung eines flammenhemmenden elastischen Bodenbelags zu nutze. The object of this patent application is to propose a flame-retardant floor covering element which is simple in construction and can be manufactured inexpensively with just a few process steps. This object is achieved by the floor covering element according to the invention with the features of claim 1. An essential basic idea of the invention is to mix a weight proportion of expandable graphite with the rubber granulate of the known elastic floor covering element before binding. The intumescent effect of expandable graphite makes it difficult for a flame front to migrate. It reduces the critical heat flow and smoke development. It also prevents burning material from dripping or falling off. The invention makes use of this effect of expandable graphite for the formation of a flame-retardant, elastic floor covering.
Das Bodenbelagselement ist erfindungsgemäß vollständig und vorzugsweise mit einem gleichbleibenden Anteil von Blähgraphit durchsetzt. Eine separate flammenhemmende Beschichtung einer Oberfläche des Bodenbelagselements ist nicht erforderlich. According to the invention, the floor covering element is completely and preferably permeated with a constant proportion of expandable graphite. A separate flame-retardant coating of a surface of the floor covering element is not necessary.
Ein weiterer Vorteil der erfindungsgemäßen Bodenbelagselemente ist, dass der aus ihnen zusammengesetzte Bodenbelag nicht vor Ort gegossen werden muss, sondern aus vorgefertigten Bodenbelagselementen auf bekannte Weise zusammengesetzt werden kann. A further advantage of the floor covering elements according to the invention is that the floor covering composed of them does not have to be poured on site, but can be assembled from prefabricated floor covering elements in a known manner.
Zur Fertigung der Bodenbelagselemente sind nur wenige Verfahrensschritte erforderlich. Hierzu ist der bekannte Herstellungsprozess nur dahingehend abzuwandeln, dass das Gummigranulat und der Blähgraphit vor oder während des Benetzen mit dem Bindemittel im gewünschten Mischungsverhältnis durchmischt werden. Only a few process steps are required to manufacture the floor covering elements. For this purpose, the known manufacturing process can only be modified so that the rubber granulate and expandable graphite are mixed in the desired mixing ratio before or during wetting with the binder.
Von besonderem Vorteil ist es, wenn das Bodenbelagselement aus dem Gummigranulat, dem Blähgraphit und dem Bindemittel besteht. Die Zusammensetzung des Bodenbelagselements nur aus diesen drei Komponenten reicht aus, um die gewünschte flammenhemmende Wirkung zu erzielen. It is particularly advantageous if the floor covering element consists of the rubber granulate, the expandable graphite and the binding agent. The composition of the floor covering element from just these three components is sufficient to achieve the desired flame-retardant effect.
Vorteilhafterweise weist der Blähgraphit einen Gewichts-Anteil von weniger als 10 % des Gesamtgewichts des elastischen Bodenbelagselements auf. Mit diesem Mischungsverhältnis wird sichergestellt, dass das Bodenbelagselement nach der EN 13501-1 für Bodenbeläge die Bedingungen der Klassifizierung Bfl - s1 als schwer entflammbarer Bodenbelag der europäischen Klasse Bfl und in Bezug auf seineThe expandable graphite advantageously has a weight fraction of less than 10% of the total weight of the elastic floor covering element. This mixing ratio ensures that the floor covering element according to EN 13501-1 for floor coverings meets the conditions of the classification B fl - s1 as heavy Flammable flooring of European class B fl and in terms of its
Rauchentwicklung von s1 übertrifft. Exceeds smoke development of s1.
In einer vorteilhaften Ausführungsform weist der Blähgraphit einen Gewichts-Anteil von 5 % bis 6 % des Gesamtgewichts des elastischen Bodenbelagselements auf. Ein derartiges Mischungsverhältnis reicht aus, um gemäß EN 13.5.2001-1 für Bodenbeläge die Norm Bfl - s1 zu erreichen. Ein solches Mischungsverhältnis wird gewählt, wenn ein möglichst effizienter Einsatz der kostentreibenden Komponente Blähgraphit angestrebt wird. In an advantageous embodiment, the expandable graphite has a weight proportion of 5% to 6% of the total weight of the elastic floor covering element. Such a mixing ratio is sufficient to achieve the B fl - s1 standard for floor coverings in accordance with EN 13.5.2001-1. Such a mixing ratio is chosen when the most efficient possible use of the cost-driving component expandable graphite is sought.
Von Vorteil ist es, wenn das Gummigranulat ein EPDM-Gummigranulat und/oder ein Recycling-Gummigranulat ist. Ist das Gummigranulat des Bodenbelagselements ein Ethylen, Propylen, Dien, Monomer (EPDM)-Gummigranulat, und/oder ein Recycling- Gummigranulat, sind die für den Fallschutz wichtigen Elastzitätsmerkmale besonders leicht zu einzustellen. Zugleich besitzt ein EPDM-Gummigranulat zum einen ein im gesamten Korn durchgehende gleiche Färbung. Zum anderen verfärbt sich das EPDM-Granulat auch unter starker und lang anhaltender Sonneneinstrahlung nicht wesentlich, wodurch in ganz besonders bevorzugter Weise ein Bodenbelagselement herstellbar ist, welches eine dauerhaft gleichbleibende Färbung des erfindungsgemäßen Bodenbelagssystems erlaubt. Ein besonderer Vorteil des Recycling-Gummigranulats ist, dass ein beispielsweise durch die Zerkleinerung von Kraftf a h rze u g reife n gewonnenes Altgummi einer weiteren Verwendung zugeführt werden kann. It is advantageous if the rubber granulate is an EPDM rubber granulate and / or a recycling rubber granulate. If the rubber granulate of the floor covering element is ethylene, propylene, diene, monomer (EPDM) rubber granulate and / or recycled rubber granulate, the elasticity characteristics that are important for fall protection are particularly easy to set. At the same time, an EPDM rubber granulate has, on the one hand, the same color throughout the entire grain. On the other hand, the EPDM granulate does not discolor significantly even under strong and long-lasting solar radiation, whereby a floor covering element can be produced in a particularly preferred manner which allows a permanently constant color of the floor covering system according to the invention. A particular advantage of the recycling rubber granulate is that old rubber obtained, for example, by the shredding of motor vehicles, can be used for further use.
Als ein Bindemittel eignet sich jedes dem Fachmann geläufige elastische Bindemittel, mit dem die Granulatteilchen untereinander verbunden werden können. Vorzugsweise ist das Bindemittel zumindest im Wesentlichen ein Polyurethan (PU), mit dem die Granulatteilchen und der Blähgraphit vorzugsweise vollständig ummantelt werden bzw. sind. Ein für die vorzugsweise vollständige Ummantelung geeigneter Gewichts- Anteil des PU am Gesamtgewicht des Bodenbelagselements beträgt 8 % bis 12 %, insbesondere 10 %. Any elastic binder known to the person skilled in the art, with which the granulate particles can be connected to one another, is suitable as a binder. The binder is preferably at least essentially a polyurethane (PU) with which the granulate particles and the expandable graphite are or are preferably completely coated. A proportion by weight of PU in the total weight of the floor covering element that is suitable for preferably complete sheathing is 8% to 12%, in particular 10%.
Von besonderem Vorteil ist es auch wenn das elastische Bodenbelagselement ein Fallschutzelement ist. Bodenbeläge, insbesondere Fallschutzbeläge, sind an sich bekannt. Das erfindungsgemäße Bodenbelagselement wirkt gegenüber einer senkrecht auf die Oberfläche des Belags wirkenden Kraft energieabsorbierend, so dass eine fallende Person — etwa ein Kind auf einem öffentlichen oder privaten Kinderspielplatz — beim Auftreffen auf das Bodenbelagselement vergleichsweise geringe Beschleunigungskräfte erfährt. Entsprechend der sinkendenIt is also of particular advantage if the elastic floor covering element is a fall protection element. Floor coverings, in particular fall protection coverings, are known per se. The floor covering element according to the invention acts in an energy-absorbing manner with respect to a force acting perpendicularly on the surface of the covering, see above that a falling person - for example a child in a public or private children's playground - experiences comparatively low acceleration forces when hitting the flooring element. According to the falling
Beschleunigungskraft sinkt die Verletzungsgefahr. Acceleration force reduces the risk of injury.
Insbesondere weist das erfindungsgemäße Bodenbelagselement auch eineIn particular, the floor covering element according to the invention also has a
Versickerungsfähigkeit auf. ln einer besonders bevorzugten Ausführungsform wird das Bodenbelagselement als Schallschutzelement wie beispielsweise eingesetzt, wie beispielsweise aus der EP 2Infiltration capacity. In a particularly preferred embodiment, the floor covering element is used as a soundproofing element such as, for example, from EP 2
463451 A1 bekannt. 463451 A1 known.
