Description

Aufsaugmatte Absorbent mat
Beschreibungdescription
Die Erfindung betrifft eine Aufsaugmatte für Öl und ölhaltige Flüssigkeiten, die aus einer saugfähigen Schicht und einer Unterlage aus einer undurchlässigen Siegelschicht besteht.The invention relates to an absorbent mat for oil and oil-containing liquids, which consists of an absorbent layer and a base of an impermeable sealing layer.
Zum Reinigen von mit Öl beschmutzten Flächen, beispielsweise Böden von Werkstätten oder Garagen, ist es bekannt, ein ölbinden- des Material, beispielsweise Sägemehl, auf die verschmutzte Fläche zu streuen; nachdem sich dieses vollgesaugt hat, muß es in verhältnismäßig mühevoller Arbeit wieder entfernt werden, wobei jedoch nicht vermieden werden kann, daß ölflecken zurückbleiben.For cleaning surfaces contaminated with oil, for example floors of workshops or garages, it is known to sprinkle an oil-binding material, for example sawdust, on the contaminated surface; after it has soaked itself up, it has to be removed with relatively great effort, but it cannot be avoided that oil stains remain.
Vielfach behilft man sich in Garagen damit, unter den Motorblock eines Kraftfahrzeuges eine Unterlage aus Pappe oder Papier zu legen, die herabtropfendes Öl auffangen soll. Vor allem im vollgesaugten Zustand kann sich eine solche Unterlage sehr leicht entzünden, so daß die Brandgefahr sehr groß ist. Außerdem läßt es sich nicht vermeiden, daß das Öl nach kurzer Zeit durch die Unterlage durchdringt und den Garagenboden verschmutzt.In garages, people often help themselves by placing a cardboard or paper surface under the engine block of a motor vehicle to catch dripping oil. Especially when fully soaked, such a pad can ignite very easily, so that the risk of fire is very high. In addition, it can not be avoided that the oil will penetrate through the pad after a short time and contaminate the garage floor.
Gegenstand der DE-A 43 26 224 ist eine Vorrichtung zum Auffangen von Öl, Benzin oder dergleichen, deren saugfähige Schicht aus einem dünnen Papierblatt besteht, dessen Rückseite zur Verhinderung eines Durchschlags von Öl versiegelt ist, beispielsweise durch eine Kunststoffschicht aus Polypropylen oder Poly- ethylen. Abgesehen davon, daß die verhältnismäßig dünne Papier- schicht nicht in der Lage ist, größere Mengen von Öl oder ölhaltigen Flüssigkeiten aufzunehmen, so daß insbesondere beim Entsorgen der Aufsaugmatte eine vorsichtige Handhabung erforderlich ist, besteht auch hier das Problem der Brandgefahr, da das mit Öl getränkte Papier vor allem in Anwesenheit von Benzin- oder Lösungsmitteldämpfen durch Glimmen oder offene Flammen sofort Feuer fängt.DE-A 43 26 224 relates to a device for collecting oil, gasoline or the like, the absorbent layer of which consists of a thin sheet of paper, the back of which is sealed to prevent oil from breaking through, for example by a plastic layer made of polypropylene or polyethylene . Apart from the fact that the relatively thin paper layer is not able to absorb large amounts of oil or oil-containing liquids, so that careful handling is particularly necessary when disposing of the absorbent mat, there is also the risk of fire here, since the paper soaked in oil is especially in the presence of petrol. or solvent vapors from smoldering or open flames catch fire immediately.
In der DE-A 33 05 223 ist ein Verfahren zum Aufsaugen von Öl auf Wasserflächen beschrieben, bei dem eine Matte aus Gewebe oder Filtervlies verwendet wird, in die Blähton oder Torfmull eingenäht ist. Derartige Vliesmatten eignen sich jedoch nicht dazu, auf einen Garagen- oder Werkstattboden gelegt zu werden, um herabtropfendes Öl aufzufangen und gleichzeitig den Boden vor Verschmutzungen zu bewahren.DE-A 33 05 223 describes a method for absorbing oil on water surfaces, in which a mat made of fabric or filter fleece is used, into which expanded clay or peat garbage is sewn. However, fleece mats of this type are not suitable for being placed on a garage or workshop floor in order to catch dripping oil and at the same time to protect the floor from dirt.
Der Erfindung liegt die Aufgabe zugrunde, eine Aufsaugmatte der eingangs angegebenen Art zur Verfügung zu stellen, die in der Lage ist, abtropfendes Öl oder ölhaltige Flüssigkeiten sicher so zu binden, daß selbst eine offene Flammenbildung keinen Brand der mit der Flüssigkeit benetzten oder vollgesaugten Matte verursachen kann.The invention has for its object to provide an absorbent mat of the type specified, which is able to bind dripping oil or oily liquids so that even an open flame does not cause a fire of the wet or soaked mat with the liquid can.
Erfindungsgemäß wird diese Aufgabe bei einer Aufsaugmatte der angegebenen Gattung dadurch gelöst, daß die saugfähige Schicht aus einem schwer entflammbaren, hochabsorbierenden und dauerhaft rückhaltefähigen Material besteht.According to the invention, this object is achieved with an absorbent mat of the type specified in that the absorbent layer consists of a flame-retardant, highly absorbent and permanently retentive material.
Bei einer derartigen Aufsaugmatte gelangt die abtropfende und aufzusaugende Flüssigkeit in die saugfähige Schicht, in der sie bis zur Entsorgung der Aufsaugmatte dauerhaft gespeichert bleibt. Da die saugfähige Schicht aus einem schwer entflammbaren Material besteht, vorzugsweise Viscose in Form von Vlies, Gewebe oder Filz, ist selbst bei einer Stichflammenbildung durch entzündete Benzindämpfe ein Brand nicht zu befürchten. Die saugfähige Schicht ist vorzugsweise . über eine Polyurethanschicht mit der Siegelschicht verbunden.In the case of such an absorbent mat, the dripping and absorbing liquid reaches the absorbent layer, in which it remains permanently stored until the absorbent mat is disposed of. Since the absorbent layer consists of a flame-retardant material, preferably viscose in the form of fleece, fabric or felt, there is no need to fear a fire, even if there is a flash of flame due to ignited gasoline vapors. The absorbent layer is preferred. connected to the sealing layer via a polyurethane layer.
Wenn die Unterlage aus der undurchlässigen Siegelschicht, die vorzugsweise ebenfalls aus einer schwer entflammbaren Folie besteht, auch die Seitenkanten der saugfähigen Schicht übergreift, steht eine allseits abgedichtete Unterlage zur Verfügung, bei der ein Entweichen der in der saugfähigen Schicht gespeicherten, ölhaltigen Flüssigkeit nach keiner Seite hin möglich ist.If the underlay made of the impermeable sealing layer, which preferably also consists of a flame-retardant film, also overlaps the side edges of the absorbent layer, there is an underlay which is sealed on all sides and in which the oily liquid stored in the absorbent layer cannot escape on either side is possible.
Die Aufsaugmatte gemäß der Erfindung eignet sich insbesondere zum Schutz von Fußböden in Garagen, Fahrzeugstellplätzen, Werkstätten, Fabrikhallen oder Heizölvorratskellern vor abtropfendem oder auslaufendem Öl und ölhaltigen Flüssigkeiten wie beispielsweise Motoröl, Getriebeöl, Schmieröl, Hydrauliköl, Dieselöl oder Heizöl. Die Aufsaugmatte kann in allen geeigneten Größen hergestellt und im Handel bereitgehalten werden, beispielsweise in Tankstellen, Verbrauchermärkten oder im Kfz-Zubehörhandel.The absorbent mat according to the invention is particularly suitable for protecting floors in garages, vehicle parking spaces, workshops, factories or heating oil storage basements from dripping or leaking oil and oil-containing liquids such as engine oil, gear oil, lubricating oil, hydraulic oil, diesel oil or heating oil. The absorbent mat can be manufactured in all suitable sizes and kept ready in the trade, for example in petrol stations, hypermarkets or in the automotive accessories trade.
Die Erfindung ist nachstehend an Ausführungsbeispielen erläutert, die in der Zeichnung dargestellt ist. Es zeigen:The invention is explained below using exemplary embodiments, which is illustrated in the drawing. Show it:
Figur 1 die Draufsicht einer Aufsaugmatte gemäß der Erfindung, Figur 2 einen schematischen Längs- oder Querschnitt der Aufsaugmatte,1 shows the top view of an absorbent mat according to the invention, FIG. 2 shows a schematic longitudinal or cross section of the absorbent mat,
Figur 3 eine Variante der Figur 2 und Figur 4 eine weitere Variante.Figure 3 shows a variant of Figure 2 and Figure 4 shows another variant.
Wie die Figuren zeigen, hat die Aufsaugmatte 10 vorzugsweise die Form eines Rechtecks, beispielsweise mit einer Breite von 70 bis 90 cm und einer Länge von 110 bis 150 cm. In Figur 2 ist zu erkennen, daß die Aufsaugmatte eine saugfähige Schicht 12 hat, die das eigentliche Speichermedium für Öl und ölhaltige Flüssigkeiten bildet. Die saugfähige Schicht 12 kann aus Viscose, Vlies, Gewebe oder Filz bestehen. Das hochabsorbierende Material dieser Schicht 12 ist dauerhaft rückhaltefähig für die aufzufan- genden Flüssigkeiten. Aus Gründen des Brandschutzes ist dieses Material schwer entflammbar. Ein besonders geeignetes Material ist unter der Bezeichnung "Lenzing Viscose FR" im Handel, eine schwer entflammbare, zellulosische Viscosefaser, der ein flammenhemmendes, halogenfreies Pigment auf Phoεphorbasis beigemischt ist (vgl. DE-A 25 32 521). Dieses Material zeichnet sich unter anderem aus durch seine permanente Schwerentflammbarkeit, seine gute Hitzeisolation, seinen guten Widerstand gegen Funken und Metallspritzer und seine geringe elektrostatische Aufladung.As the figures show, the absorbent mat 10 preferably has the shape of a rectangle, for example with a width of 70 to 90 cm and a length of 110 to 150 cm. In Figure 2 it can be seen that the absorbent mat has an absorbent layer 12 which forms the actual storage medium for oil and oil-containing liquids. The absorbent layer 12 can consist of viscose, fleece, fabric or felt. The highly absorbent material of this layer 12 is permanently retentive for the liquids. This material is flame retardant for reasons of fire protection. A particularly suitable material is commercially available under the name "Lenzing Viscose FR", a flame-retardant, cellulosic viscose fiber to which a flame-retardant, halogen-free pigment based on phosphorus has been added (cf. DE-A 25 32 521). This material is characterized, among other things, by its permanent flame resistance, its good heat insulation, its good resistance to sparks and metal splashes and its low electrostatic charge.
Wie Figur 2 weiter zeigt, ist die saugfähige Schicht 12 auf ihrer Unterseite durch eine Folie aus einer undurchlässigen Siegelschicht 14 abgedeckt, die mit der oberen Schicht 12 über eine Polyurethanschicht 16, vorzugsweise PU-Schaum, verklebt ist. Auch die Siegelschicht 14 besteht vorzugsweise aus einer PU-Folie.As FIG. 2 further shows, the absorbent layer 12 is covered on its underside by a film made of an impermeable sealing layer 14, which is glued to the upper layer 12 via a polyurethane layer 16, preferably PU foam. The sealing layer 14 also preferably consists of a PU film.
Bei der Variante der Figur 3 übergreift die Folie (Siegelschicht 14) alle Seitenkanten 18 der saugfähigen Schicht 12.In the variant in FIG. 3, the film (sealing layer 14) overlaps all side edges 18 of the absorbent layer 12.
Im Beispiel der Figur 4 hat die Aufsaugmatte 10 einen sandwichartigen Aufbau, bei dem die schwer entflammbare Schicht 12 aus zwei Lagen 12' und 12'' besteht, von denen die obere Lage 12' beispielsweise bessere Rückhaltefähigkeiten und Brandschutzeigenschaften als die untere Lage 12* ' aufweist, die aus einem ebenfalls noch schwer entflammbaren Material besteht.In the example of FIG. 4, the absorbent mat 10 has a sandwich-like structure, in which the flame-retardant layer 12 consists of two layers 12 'and 12' ', of which the upper layer 12', for example, has better retention and fire protection properties than the lower layer 12 * ' has, which also consists of a flame retardant material.
Die Schichten 12 und 14 der Aufsaugmatte 10 bestehen aus biologisch abbaubarem und wiederverwertbarem Material, so daß eine problemlose Entsorgung der gebrauchten Aufsaugmatte 10 möglich ist, beispielsweise in Verbrennungsanlagen, in denen die gewonnene Energie für Heizzwecke genutzt werden kann. Die Aufsaugmatte eignet sich nicht nur zum Schutz von Garagen- oder Werkstattböden, sondern auch als Unterlage für ölbenetzte Teile bei Reparaturarbeiten, beispielsweise Motor- und Getriebeteile, und für Auffanggefäße bei einem Motor- oder Getriebeölwechsel.The layers 12 and 14 of the absorbent mat 10 consist of biodegradable and recyclable material, so that the used absorbent mat 10 can be disposed of without problems, for example in incineration plants in which the energy obtained can be used for heating purposes. The absorbent mat is not only suitable for protecting garage or workshop floors, but also as a base for oil-soaked parts for repair work, for example engine and transmission parts, and for collecting vessels when changing the engine or transmission oil.
Figur 1 zeigt, daß die Oberseite der Aufsaugmatte 10 mit Verwendungshinweisen bedruckt werden kann, beispielsweise mit verkehrsüblichen Stop-Zeichen 20, die als Einparkhilfe dienen, wenn die Aufsaugmatte 10 auf einem Garagenboden liegt. FIG. 1 shows that the top of the absorbent mat 10 can be printed with usage instructions, for example with stop signs 20 which are customary in traffic and which serve as a parking aid when the absorbent mat 10 lies on a garage floor.
