Description

Ummantelung für elektrische Kabel und Leitungen Zusatz zum Patent 887 964 In der Patentschrift 887 964 sind für isolierte elektrische Leitungen oder Kabel Ummantelungen beschrieben, die aus polymerisierten Derivaten der Acrylsäure bestehen, denen Füllstoffe zugesetzt sind. Diese Kabelummantelungen genügen im allgemeinen den gestellten Ansprüchen. Für gewisse Fälle ist es erwünscht, ein Mantelmaterial zu besitzen, das unter Beibehaltung der wertvollen Eigenschaften dieser Massen sich durch eine hohe Druckfestigkeit auch bei erhöhten Temperaturen auszeichnet.Sheathing for electrical cables and wires. Patent addition 887 964 In the patent specification 887 964 are for insulated electrical lines or Cable sheaths are described which are made from polymerized derivatives of acrylic acid exist, to which fillers are added. These cable sheaths are generally sufficient the demands made. In certain cases it is desirable to have a jacket material to own that while maintaining the valuable properties of these masses themselves characterized by high compressive strength even at elevated temperatures.

Es wurde nun gefunden, daß durch den Zusatz von Chloropren (polymeres Clilor-2-Butadien-i, 3) zu den Mantelmassen nach Patent 887 964 Massen erhalten werden, die einem vulkanisationsähnlichen Prozeß unterworfen werden können, wobei der thermoplastische Zustand weitgehend beseitigt wird.It has now been found that the addition of chloroprene (polymeres Clilor-2-butadiene-i, 3) obtained for the jacket masses according to patent 887,964 masses which can be subjected to a vulcanization-like process, wherein the thermoplastic state is largely eliminated.

Es ist bereits bekannt, Butadien gemeinsam mit Derivaten der Acrylsäure zu polymerisieren und dann einem Vulkanisationsprozeß zu unterwerfen, wobei weicligummiähnliche Massen erhalten werden. Demgegenüber besitzen die Mantelmassen gemäß der Erfindung den Vorteil einer erhöhten C51-, Alterungs- und Ozonbeständigkeit sowie eine Herabgeminderte Brennbarkeit. Für dien erfindungsgemäßen Verwendungszweck sind diese Eigenschaften von großer Bedeutung, da bei elektrischen Kabeln und Leitungen häufig mit der Anwesenheit von 01 oder Ozon gerechnet werden muß. Auch in bezug auf .Mterungsbeständigkeit werden sehr hohe Anforderungen gestellt. Außerdem ist es van Wert, daß die Brandsicherheit durch derartige Zusätze möglichst erhöht wird.It is already known that butadiene can be polymerized together with derivatives of acrylic acid and then subjected to a vulcanization process, with compounds similar to white rubber being obtained. In contrast, the coating compounds according to the invention have the advantage of increased C51, aging and ozone resistance and reduced flammability. These properties are of great importance for the purpose according to the invention, since the presence of oil or ozone must often be expected in electrical cables and lines. Very high requirements are also placed on aging resistance. In addition, it is of value that the fire safety is increased as much as possible by such additives.

Die Herstellung der erfindungsgemäßen Massen kann in der Weise erfolgen, daß man das Chloro-Aren zunächst für sich mit Füllstoffen und gegebenenfalls auch mit Weichmachern, Antoxydantien, Schwefel u..dgl. mischt und diese Mischung mit einer gesondert hergestellten Mischung nach dem Patent 887 964 auf Walzen @od. d'gl. verarbeitet. Man kann aber auch so verfahren,.daß zunächst das Chloropren mit den polymerisierten Acrylsäurederivaten vereinigt wird und dann die erforderlichen Zusatzstoffe beigegeben werden.The compositions according to the invention can be prepared in such a way that that you can first use the chloro-arene with fillers and, if necessary, also with plasticizers, antioxidants, sulfur and the like. mixes and this mix with a separately prepared mixture according to the patent 887 964 auf Walzen @od. d'gl. processed. But one can also proceed in such a way that first the chloroprene with the polymerized acrylic acid derivatives is combined and then the necessary additives be added.

Es kommen für den Verwendungszweck Mischungen in Frage, die Chloropren und polymerisierte Acrylsäurederivate im Verhältnis io:9o bis 50:5o enthalten. Die so erhaltenen :Mischungen sind weich und geschmeidig und lassen sich beispielsweise auf der Strangpresse gut verarbeiten. Nach der Verformung wird das ummantelte Kabel in bekannter Weise durch eine Wärmebehandlung vulkanisiert. Man hat es in .der Hand, u. a. durch Wahl eines mehr oder weniger harten Chloroprens, Mantelmassen von härterer oder weicherer Beschaffenheit den Erfordernissen entsprechend herzustellen.Mixtures, the chloroprene, can be used for this purpose and polymerized acrylic acid derivatives in a ratio of 10: 9o to 50: 5o. the so obtained: Mixtures are soft and pliable and can be for example Process well on the extruder. After the deformation, the sheathed cable becomes vulcanized in a known manner by a heat treatment. You have it in your hand i.a. by choosing a more or less hard chloroprene, sheath masses of harder or of a softer quality according to the requirements.
