Abstract

The invention relates to a polymer mixture for sheathing cables and lines. Part of this mixture is a propylene homopolymer or copolymer having a melt flow index of from 0.5 to 100 g/10 min, measured at 230 DEG C/216 kg. Polyethylene and/or synthetic rubber is admixed with this polymer as mixing partner. A further constituent of the polymer mixture is a flameproofing agent comprising an intumescent system based on ammonium polyphosphate or a metal hydroxide.

Description

Die Erfindung betrifft eine Polymermischung für die Ummantelung von Kabeln und Leitungen. Für solche Anwendungsgebiete werden nach dem Stand der Technik weichgemachte PVC-Materialien in verschiedenen Shore-Härten eingesetzt. Auch Kunstkautschuk-Mischungen sind hierfür bereits eingesetzt worden. Zum Stand der Technik wird verwiesen auf das Deutsche Gebrauchsmuster 76 41 030, in dem ein biegsamer Leitungs­ trägerstreifen beschrieben ist, der aus einem thermoplastischen Mate­ rial oder einem synthetischen Kautschuk besteht, in dem eine oder meh­ rere elektrische Leitungen verlegt sind. Soweit solche Kabelummante­ lungen aus weichgemachten Polyvinylchlorid bestehen, sind diese halo­ genhaltig und setzen bei Verbrennung giftige Halogenwasserstoffe frei.The invention relates to a polymer mixture for the sheathing of Cables and wires. For such applications, according to State of the art plasticized PVC materials in various Shore hardness used. Synthetic rubber compounds are also used for this already been used. The state of the art is referred to German utility model 76 41 030, in which a flexible pipe Carrier strip is described, which is made of a thermoplastic mate rial or a synthetic rubber in which one or more rere electrical lines are laid. So much for such cable sheaths lungs made of plasticized polyvinyl chloride, these are halo genetically and release toxic hydrogen halide when burned.

Dieser Nachteil läßt sich bei der Verwendung von Synthesekautschuk für die Kabelummantelung vermeiden. Hier ist jedoch der Nachteil eines sehr kostenintensiven Ummantelungsmaterials zu sehen, wodurch der Ein­ satz auf Spezialanwendungsgebiete begrenzt ist.This disadvantage can be found when using synthetic rubber avoid cable sheathing. However, the disadvantage here is one to see very expensive sheathing material, which makes the one set is limited to special areas of application.

Als halogenfreie Variante solcher Kabelummantelungen sind in der Ver­ gangenheit auch schon Polyethylen und dessen Copolymere mit und ohne halogenfreiem Flammschutz eingesetzt worden. Diese Grundmaterialien haben neben dem Vorteil der Halogenfreiheit aber den Nachteil, daß sie im höheren Temperaturbereich nur eingeschränkt verwendbar sind.As a halogen-free variant of such cable sheathing are in the Ver Polyethylene and its copolymers with and without halogen-free flame protection has been used. These basic materials have the disadvantage of freedom from halogen but the disadvantage that they can only be used to a limited extent in the higher temperature range.

Hier setzt die Erfindung ein, die es sich zur Aufgabe gestellt hat, gegenüber den aus dem Stand der Technik bekannten Ummantelungsmateria­ lien ein steiferes Material anzugeben, welches erhöhte Zugfestigkeit aufweist und welches durch spezielle Mischungspartner beliebig ein­ stellbare Endeigenschaften aufweist. This is where the invention comes in, which has set itself the task of compared to the casing material known from the prior art lien to specify a stiffer material, which increased tensile strength and which one by any special mixing partner adjustable final properties.  

Erfindungsgemäß wird hier ein Polypropylen-Homo- oder Copolymer mit einem Schmelzindex von 0,5 bis 100 g/10 Min. unter Verwendung der Meß­ methode 230°C/2,16 kg eingesetzt, dem als Mischungspartner Polyethy­ len und/oder Synthesekautschuk sowie Flammschutzmittel aus einem Intu­ meszenzsystem auf Basis Ammoniumpolyphosphat oder einem Metallhydroxid zugemischt sind.According to the invention, a polypropylene homo- or copolymer is used here a melt index of 0.5 to 100 g / 10 min. using the meas method 230 ° C / 2.16 kg used, the mixing partner Polyethy len and / or synthetic rubber and flame retardants from one Intu Mescence system based on ammonium polyphosphate or a metal hydroxide are mixed.

Durch die Verwendung der erfindungsgemäßen Mischungen aus Polypropylen mit Polyethylen und/oder Synthesekautschuk und dem speziellen Flamm­ schutzmittel lassen sich die Eigenschaften der Ummantelungsmate­ rialien in einem weiten Bereich einstellen, insbesondere was die Flexibilität und die Zugfestigkeit/Reißdehnung der Ummantelung be­ trifft. Wesentliches Merkmal der erfindungsgemäßen Mischung ist die Tatsache, daß die genannten guten Eigenschaften bei zunehmender Wärme­ belastung weitgehend erhalten bleiben. Durch Verwendung der verschie­ denen Schmelzindizes des Polypropylen kann zudem individuell auf die Parameter der Verarbeitbarkeit eingegangen werden.By using the mixtures of polypropylene according to the invention with polyethylene and / or synthetic rubber and the special flame The properties of the coating material can be protected rialien in a wide range, especially what the Flexibility and the tensile strength / elongation at break of the sheathing be meets. The essential feature of the mixture according to the invention is that The fact that the good properties mentioned with increasing heat the burden remains largely intact. By using the various which melt indices of polypropylene can also be customized to the Processability parameters are addressed.

Mit den erfindungsgemäßen Polymermischungen erzielt man ein maßge­ schneidertes, halogenfreies Ummantelungsmaterial mit entsprechendem Flammschutz für verschiedene Einsatzzwecke. Hierbei ist wesentlich, daß die guten Isolationseigenschaften des Polypropylens weitgehend erhalten bleiben.With the polymer mixtures according to the invention, a dimension is achieved Tailored, halogen-free sheathing material with the appropriate Flame retardants for various purposes. Here it is essential that the good insulation properties of polypropylene largely remain.

Die Verwendung von Polypropylenhomopolymer ohne die Beimischung von Synthesekautschuk ergibt ein sehr steifes Ummantelungsmaterial mit hoher Zugfestigkeit. Demgegenüber resultiert aus der Verwendung von Polypropylen-Copolymer mit hohen Anteilen von Polyethylen und/oder Synthesekautschuk ein relativ flexibles Ummantelungsmaterial mit erhöhter Reißdehnung bzw. Streckbarkeit.The use of polypropylene homopolymer without the addition of Synthetic rubber results in a very stiff covering material high tensile strength. In contrast, the use of Polypropylene copolymer with high proportions of polyethylene and / or Synthetic rubber with a relatively flexible sheathing material increased elongation at break or stretchability.

Bei der erfindungsgemäßen Polymermischung hat sich als zweckmäßig er­ wiesen, daß der Mengenanteil des Polypropylen-Homo- oder Copolymers 20-100 Gewichtsprozent beträgt. In the polymer mixture according to the invention, it has been found to be expedient indicated that the proportion of the polypropylene homo- or copolymer Is 20-100 percent by weight.  

Auf diese Weise lassen sich die speziellen Eigenschaften des Ummante­ lungsmaterials individuell einstellen.In this way, the special properties of the ummante Adjustment material individually.

Das gleiche gilt für den Mengenanteil des Polyethylen- und/oder Syn­ thesekautschuks, der erfindungsgemäß 0,1 bis 40 Gewichtsprozent betra­ gen soll. Hierdurch läßt sich die Flexibilität und die Zugfestigkeit/ Reißdehnung des Ummantelungsmaterials beeinflussen.The same applies to the proportion of polyethylene and / or syn thesis rubber, which according to the invention amounts to 0.1 to 40 percent by weight should. This allows flexibility and tensile strength / Affect the elongation at break of the sheathing material.

Schließlich erscheint es zweckmäßig, daß der Anteil des halogenfreien Flammschutzmittels, 1-5 Gewichtsprozent beträgt. Diese Variationsmög­ lichkeiten der eingesetzten Menge an Flammschutzmitteln ermöglicht die Erfüllung der diversen Brandanforderungen nach verschiedenen Normen.Finally, it seems appropriate that the proportion of halogen-free Flame retardant, 1-5 weight percent. This possible variation of the amount of flame retardants used Fulfillment of the various fire requirements according to different standards.

In der nachfolgenden Tabelle sind verschiedene Rezepturbeispiele einer Polymermischung aus Polypropylen flammgeschützt angegeben, wobei die Materialeigenschaften dieser speziellen Mischungen nachfolgend ange­ geben sind:The following table shows various recipe examples of one Polymer mixture of polypropylene indicated flame retardant, the Material properties of these special mixtures are given below are:
