Description

AT 404 749 BAT 404 749 B

Die Erfindung betrifft eine flexible wasserdurchlässige mehrschichtige Matte zum Schutz gegen Pflanzenwurzeln.The invention relates to a flexible, water-permeable, multi-layer mat for protection against plant roots.

Es ist bekannt, daß Kupfer, insbesondere Kupferfolie, bremsend auf Pflanzenwurzeln wirkt. Für großflächige Abschirmungen, insbesonders bei Flachdachaufbauten, wurden zu diesem Zweck bisher bituminierte 5 Dachpappenbahnen mit Kupfereinlage oder auch grobmaschige Kupfernetze verwendet.It is known that copper, in particular copper foil, has a braking effect on plant roots. For large-scale shielding, especially in the case of flat roof structures, 5 bituminized roofing felt sheets with copper inlay or coarse-meshed copper nets were used for this purpose.

So ist beispielsweise in der DE 28 27 136 A1 eine bituminierte Dachbahn beschrieben, die aus einem Vlies, einer gefältelten Metallfolie, beispielsweise einer Aluminium- oder Kupferfolie und einer Bitumenschicht besteht. Diese Dachbahn wird zum Abdichten von Dächern verwendet, wobei die Metallfolie zur Wärmereflexion dienen soll. io In der DE 42 23 761 A1 wird eine Bitumendachbahn mit einem an der Oberfläche aufkaschierten Kunstfaservlies beschrieben, wobei das Kunstfaservlies zur Vermeidung des Einwachsens von Wurzelfäden in die Bitumenschicht elementares Kupfer enthält. Diese Wirkung als Wurzelbremse kann allerdings bei dieser Dachbahn nur sehr kurzfristig sein, da sich das elementare Kupfer aufgrund des aufgebrachten Substrats (i.a. Erde beim Anlegen von Dachgärten) rasch auf chemischen Weg umwandelt und somit seine 15 Wirkung als Wurzelbremse verliert.For example, DE 28 27 136 A1 describes a bituminized roofing membrane which consists of a fleece, a pleated metal foil, for example an aluminum or copper foil and a bitumen layer. This roofing membrane is used to seal roofs, with the metal foil being used for heat reflection. DE 42 23 761 A1 describes a bitumen roofing membrane with a synthetic fiber fleece laminated to the surface, the synthetic fiber fleece containing elemental copper to prevent root threads from growing into the bitumen layer. However, this effect as a root brake can only be very short-term with this roofing membrane, since the elemental copper quickly changes chemically due to the substrate applied (e.g. earth when creating roof gardens) and thus loses its effect as a root brake.

Diese wasserundurchlässigen, bituminisierten Dachbahnen sind aufgrund der Bitumengrundschicht relativ steif und unflexibel, wodurch bei der Herstellung nur begrenzte Breiten und Flächen der Dachbahn gefertigt werden können. Ferner hat die Verwendung von Bitumen den Nachteil des Versprödens.These waterproof, bituminized roofing membranes are relatively stiff and inflexible due to the bitumen base layer, which means that only limited widths and areas of the roofing membrane can be produced. Furthermore, the use of bitumen has the disadvantage of becoming brittle.

Die in der DE 3444669 A1 beschriebene Deckung für Dächer, Fassaden usw. beschreibt einen 20 wasserdurchlässigen Verbundkörper aus Schaumstoff (vgl. S.6 letzter Absatz), wobei die metallische Außenhaut hauptsächlich dekorativen Zwecken dient (vgl. S.5 Absatz 3), aber auch Reißfestigkeit und Korrossionsbeständigkeit der Deckung erhöhen soll. Eine Wirkung gegen das Ein- und/oder Durchdringen von Wurzeln wird nicht erwähnt.The covering for roofs, facades, etc. described in DE 3444669 A1 describes a 20 water-permeable composite body made of foam (see p. 6 last paragraph), the metallic outer skin mainly serving decorative purposes (see p. 5 paragraph 3), but should also increase the tensile strength and corrosion resistance of the cover. An effect against the penetration and / or penetration of roots is not mentioned.

Aufgabe der Erfindung ist es, eine wasserdurchlässige flexible Wurzelbremsmatte bereitzustellen, die 25 großflächig gefertigt werden kann, hohe Zugfestigkeit und langfristige Wurzelbremswirkung aufweist und auch bedenkenlos in kritischen Anwendungsgebieten, beispielsweise bei der Abdeckung von Deponien, beim Schutz von Kanalbauten u.dgl. eingesetzt werden kann.The object of the invention is to provide a water-permeable, flexible root brake mat which can be produced over a large area, has high tensile strength and long-term root braking effect and also without hesitation in critical areas of application, for example when covering landfills, when protecting sewer structures and the like. can be used.

Gegenstand der Erfindung ist daher eine mehrschichtige wasserdurchlässige Matte als Wurzelbremse, dadurch gekennzeichnet, daß sie aus mindestens einer Schicht Kupferfolie, und mindestens einer Schicht 30 aus nadelbarem Vlies besteht, wobei die Schichten durch Vernadeln miteinander verbunden sind.The invention therefore relates to a multilayer water-permeable mat as a root brake, characterized in that it consists of at least one layer of copper foil and at least one layer 30 of needle-punched nonwoven, the layers being connected to one another by needling.

Die erfindungsgemäße Matte kann gegebenenfalls zusätzliche Schichten aufweisen, beispielsweise auffixierte Sandkörner zur Erhöhung der Abriebfestigkeit, der UV-Beständigkeit und der Brandbeständigkeit, Asche zur Erhöhung der Brandbeständigkeit und der Durchstanzverbesserung, Korkschichten, Kunststoffolien, Aktivkohle, Zeolith, poröse Mineralstoffe u.dgl. zur Erhöhung der Absorbtionsfähigkeit. Latex Gewebe, 35 Gewirke zur Erhöhung der Zugfestigkeit, Wärmedämmaterialien, Drainagematerialien und dergleichen. Diese Materialien können als zusätzliche Schichten vorgesehen sein, aber auch direkt in die Vliesschichte eingearbeitet werden.Eine Erhöhung der Zugfestigkeit kann auch durch in das nadelbare Vlies ein- bzw. aufgebrachte zugfeste Fäden erreicht werden.The mat according to the invention can optionally have additional layers, for example fixed grains of sand to increase abrasion resistance, UV resistance and fire resistance, ash to increase fire resistance and improve punching, cork layers, plastic films, activated carbon, zeolite, porous minerals and the like. to increase the absorption capacity. Latex fabrics, 35 knitted fabrics for increasing tensile strength, thermal insulation materials, drainage materials and the like. These materials can be provided as additional layers, but can also be incorporated directly into the nonwoven layer. An increase in tensile strength can also be achieved by means of tension-resistant threads inserted or applied in the needlable nonwoven.

Die Kupferfolie kann auch vorbehandelt und/oder oberflächenbeschichtet sein (oder verschiedene 40 Substanzen beigemischt haben), wodurch z.B. die Korrosionsbeständigkeit der Matte erhöht werden kann.The copper foil can also be pretreated and / or surface-coated (or have mixed in various substances), e.g. the corrosion resistance of the mat can be increased.

Die erfindungsgemäße Matte weist eine Dicke von etwa 0,2 bis 5 cm oder mehr auf. Die Dicke der eingebrachten Kupferfolie hängt von der geforderten Stabilität gegen das Einwachsen von Wurzeln ab und kann beispielsweise etwa 0,01 bis 0,1 mm betragen.The mat according to the invention has a thickness of about 0.2 to 5 cm or more. The thickness of the copper foil introduced depends on the required stability against root ingrowth and can be, for example, about 0.01 to 0.1 mm.

Die Wahl des Grundvlieses hängt ebenso wie gegebenenfalls die Wahl einer Abdeck- und/oder 45 Verstärkungsschicht hauptsächlich von den zu erwartenden mechanischen Belastungen ab. Verwendbare Vliese weisen beispielsweise Flächengewichte von 100 - 500 g/m2 auf.The choice of the basic fleece, as well as the choice of a covering and / or reinforcement layer, depends mainly on the mechanical loads to be expected. Usable nonwovens have, for example, basis weights of 100-500 g / m2.

Die erfindungsgemäße Matte weist gegenüber der bekannten bituminisierten Wurzelbremsmatte eine bedeutend höhere Flexibilität, aber auch höhere Lebensdauer und Zugfestigkeit auf, sodaß eine großflächige Fertigung und Anwendung möglich ist. So können beispielsweise Matten mit einer Breite von 5 m und so einer Länge von 50 m einfach hergestellt und auch gehandhabt werden. Dies erlaubt eine durchgehende Befestigung großer Flächen. Durch die größere Flexibilität müssen aber auch etwa notwendige Überlappungen bei Verwendung von mehreren Bahnen nicht (können jedoch) durch Verkleben, Vernähen und dergleichen, miteinander verbunden werden.The mat according to the invention has a significantly higher flexibility than the known bituminized root brake mat, but also a longer service life and tensile strength, so that large-scale production and use is possible. For example, mats with a width of 5 m and a length of 50 m can be easily manufactured and handled. This allows large areas to be fixed throughout. Due to the greater flexibility, however, any necessary overlaps when using multiple webs do not (but can) be connected to one another by gluing, sewing and the like.

Aufgrund ihrer Eigenschaften kann die erfindungsgemäße Matte beispielsweise bei der Abdeckung von 55 Deponien oder als Schutzlage beim Kanalbau verwendet werden. Durch ihre Flexibilität paßt sie sich dabei der nachsinkenden und sich dabei verformenden Deponieoberfläche an (die bekannten Bitumen-Dachbahnen sind dafür ungeeignet). Bei Kanalrohren wiederum können Längsstreifen der erfindungsgemäßen Wurzelbremsmatte eingebaut und anschließend der Länge nach über dem Rohr überlappend zusammenge- 2Due to its properties, the mat according to the invention can be used, for example, when covering 55 landfills or as a protective layer in sewer construction. Due to its flexibility, it adapts to the sinking and deforming landfill surface (the known bitumen roofing membranes are unsuitable for this). In the case of sewer pipes, in turn, longitudinal strips of the root brake mat according to the invention can be installed and then overlapped lengthwise over the pipe

AT 404 749 B schlagen werden. Als Alternative kann die Schutzmatte beispielsweise als Einlage in die Rohrschalung schon bei der Herstellung der Kanalrohre eingebracht werden, wobei sich dann die rauhe Vliesoberfläche beim Aushärten des Betons mit diesem dauerhaft verbindet. Ein Beispiel für eine erfindungsgemäße Matte ist in Fig. 1 dargestellt. Darin bedeutet 1 ein Unterlagsvlies, das gegebenenfalls auch ein Gewebe, Gewirke oder eine Kunststoffolie sein kann, 2 eine Kupferfolie, 3 ein nadelbares Vlies. Zur Herstellung der Matte bringt man in einem fortlaufenden Verfahren auf das Unterlagsvlies (1), beispielsweise 200 g/m2, die Kupferfolie (2), z.B. 0,032 mm, auf. Darüber legt man das Vlies (3), z.B. 200 g/m2, und vernadelt das ganze Paket mit einer herkömmlichen Nadelmaschine. Dabei durchstechen wiederhakenbesetzte Nadeln 10-tausende Male/m2 (vorzugsweise 5 - 80 Einstiche/cm2) das Deckvlies (3), nehmen von diesem Fäden mit, durchstechen weiters die Kupferfolie (2), wodurch diese wasserdurchlässig wird, und das Unterlagsgewebe (1), mit dem sich die Fäden des Deckvliese (3) verschlingen, über Reibung verbinden und somit das Schichtpaket Zusammenhalten. Zur Verbesserung des Verfahrens kann das Produkt zusätzlich an der Unterseite thermisch oder mit Klebstoff/Harz behandelt werden. Dieses Produkt ist zugfest, flexibel, wasserdurchlässig- und somit als Filter verwendbar, langlebig, abriebfest, wurzeltest, kostengünstig, leicht, mit Messer oder Schere schneidbar, die Kupferfolie ist aufbeiden Seiten geschützt. Als Grundversion kann die zuvor beschriebene Version auch ohne Unterlagsvlies (1) vernadelt werden, wodurch sie jedoch weniger zugfest wird. Weiters können die Wurzelschutzmatten zusätzliche Materialien und Schichten aufweisen. z.B.: aufgesprühtes Bitumen (Hitzebeständigkeit), auffixierte Sandkörner (Abriebfestigkeit, UV-Schutz, Brandbeständigkeit.....), zusätzliche Kleber, Kunstharz, auffixierter Kork, Kunststoffo lien (Wasserdichtheit,..), Latex, Gewebe, Gewirke, Schaumstoffe, biologisch abbaubare Materialien, weitere Kupferfolien- und Vliesschichten (z.B. als Durchstanzverbesserung). Diese Materialien könne auch in und/oder zwischen den Schichten eingebracht werden, z.B. eine Lage Asche (ca. 0,5 - 12 mm, als Durchstanzverbesserung, Brandhemmung.....) zwischen das Deckvlies (3) und der Kupferfolie (2) bei Variante 1. Weiters Materialien wie: Aktivkohle, Zeolith, rieselfähige (eventuell poröse) Mineralstoffe, Kork, Gips, Zement, Torf, Holzspäne, Wärmedämmaterial, Bentonit, Sand, Verstärkungsfaden, Brandhemmer, Drainagematerialien, usw.. Derartige Matten mit demselben prinzipiellen Aufbau, bzw. die entsprechenden Varianten können auch andere Funktionen erfüllen. Z.B.: elektromagnetische Abschirmung, Wärmedämmung, Brandhemmung, Stromleitung, Erdung, Verpackung, Bauelement, Einrichtungs- oder Möbelelement, Harzgrundelement, Aufsaugmatten, Heilbehelf, Belag, Lichtabschirmung, usw.. Patentansprüche 1. Mehrschichtige, luft- und wasserdurchlässige Matte mit einer Kupferfolie als Wurzelbremse, dadurch gekennzeichnet, daß sie aus mindestens einer Schicht aus nadelbarem Vlies 3 und einer mit dieser Vliesschicht 3 vernadelten Schicht aus Kupferfolie 2 besteht.AT 404 749 B. As an alternative, the protective mat can be introduced, for example, as an insert in the pipe formwork during the manufacture of the sewer pipes, the rough fleece surface then permanently bonding to the concrete when it hardens. An example of a mat according to the invention is shown in FIG. 1. Therein 1 means an underlay fleece, which can optionally also be a woven, knitted or plastic film, 2 a copper foil, 3 a needlable fleece. In order to produce the mat, the copper foil (2), e.g. 0.032 mm, on. The fleece (3), e.g. 200 g / m2, and needles the whole package with a conventional needle machine. In doing so, barbed needles pierce the cover fleece (3) ten thousand times / m2 (preferably 5 - 80 punctures / cm2), take away from this thread, further pierce the copper foil (2), which makes it permeable to water, and the underlay fabric (1) , with which the threads of the nonwoven (3) intertwine, connect via friction and thus hold the layer package together. To improve the process, the bottom of the product can also be treated thermally or with adhesive / resin. This product is tensile, flexible, permeable to water and therefore usable as a filter, durable, abrasion-resistant, root-tested, inexpensive, light, can be cut with a knife or scissors, the copper foil is protected on both sides. As the basic version, the version described above can also be needled without underlay fleece (1), but this makes it less tensile. Furthermore, the root protection mats can have additional materials and layers. eg: sprayed on bitumen (heat resistance), fixed grains of sand (abrasion resistance, UV protection, fire resistance .....), additional glue, synthetic resin, fixed cork, plastic oils (water resistance, ..), latex, fabrics, knitted fabrics, foams, biodegradable materials, further layers of copper foil and fleece (e.g. to improve punching). These materials can also be incorporated in and / or between the layers, e.g. a layer of ash (approx. 0.5 - 12 mm, as punching improvement, fire resistance .....) between the cover fleece (3) and the copper foil (2) in variant 1. Furthermore, materials such as: activated carbon, zeolite, free-flowing (possibly porous) minerals, cork, gypsum, cement, peat, wood shavings, thermal insulation material, bentonite, sand, reinforcing thread, fire retardants, drainage materials, etc. Such mats with the same basic structure, or the corresponding variants, can also perform other functions. For example: electromagnetic shielding, thermal insulation, fire resistance, power line, grounding, packaging, component, furnishing or furniture element, resin base element, absorbent mats, remedies, covering, light shielding, etc. Claims 1.
