Description
Ummantelung für isolierte elektrische Leitungen oder Kabel In der Patentschrift 887 964 wird eine isolierte elektrische Leitung oder ein Kabel mit einer Ummantelung beschrieben, die aus polymerisierten Derivaten der Acrylsäure für sich oder im Gemisch miteinander besteht mit einem Zusatz von 4o bis 9o % eines oder mehrerer Füllstoffe. Eine Ummantelung gemäß dem Patent weist sehr wertvolle Eigenschaften auf, wie beispielsweise absolute C51-, hohe Alterungs-, Wasser- und Säurebeständigkeit, die das Material für seine Verwendung als Ummantelungsmaterial an Stelle von Blei besonders geeignet machen.Sheathing for insulated electrical lines or cables In the Patent specification 887 964 is an insulated electrical wire or cable with described a sheath made of polymerized derivatives of acrylic acid on its own or in a mixture with one another, with an addition of 40 to 90% of one or more fillers. A jacket according to the patent has very valuable Properties such as absolute C51, high aging, water and Acid resistance, which makes the material suitable for its use as a cladding material make it particularly suitable in place of lead.
Da das Material unter Verwendung von reversibel thermoplastischen Stoffen hergestellt ist, liegt es in der Natur der Massen, daß sie bei höheren Temperaturen von dem elastischen in einen sehr plastischen Zustand übergehen, während umgekehrt bei tieferen Temperaturen sich das Material in einem Zustand geringerer Geschmeidigkeit befindet.Because the material using reversible thermoplastic When substances are manufactured, it is in the nature of the masses that they operate at higher temperatures change from the elastic to a very plastic state, while vice versa at lower temperatures the material becomes less pliable is located.
Für gewisse Zwecke ist es nun erwünscht, über ein Material zu verfügen, das innerhalb eines breiten Temperaturbereiches mehr elastische Eigenschaften beibehält. In der Praxis hat sich herausgestellt, daß in verschiedenen Fällen eine absolute ölbeständigkeit des Mantelmaterials nicht erforderlich ist, so daß den in der Patentschrift 887 964 beschriebenen Massen Zusätze in geringere Mengen zugegeben werden können, die an sich keine Ölbeständigkeit aufweisen. Bei Verwendung derartiger Zusätze, wie z. B. plastizierter Altgummi bzw. Regenerat in Höhe bis zu roo/o, hat sich überraschenderweise herausgestellt, daß die mechanischen Eigenschaften der in der Patentschrift 887 964 verwendeten Masse in dem beschriebenen Sinne verbessert werden können.For certain purposes it is now desirable to have a material which retains more elastic properties over a wide temperature range. In practice it has been found that in various cases an absolute Oil resistance of the jacket material is not required, so that in the patent 887 964 described mass additives can be added in smaller amounts, which in themselves have no oil resistance. When using such additives, such as B. plasticized old rubber or regrind in the amount of up to roo / o, has surprisingly turned out to be the mechanical Properties of the patent specification 887 964 used mass can be improved in the sense described.
Eine derartige Masse kann z. B. vorteilhafterweise bestehen aus: 30,5o Teilen polymerisiertem Äthylacrylat, 9,0o Teilen Regenerat (70% Kautschuksubstanz), 0,7o Teilen ß-Naphthol, 0,8o Teilen Stearinsäure, 36,0o Teilen Talkum, 23,0o Teilen Ruß.Such a mass can, for. B. advantageously consist of: 30.5o Parts of polymerized ethyl acrylate, 9.0o parts of regenerated material (70% rubber substance), 0.7o parts of β-naphthol, 0.8o parts of stearic acid, 36.0o parts of talc, 23.0o parts Soot.
Die oben beschriebene Masse besitzt z. B. eine erhöhte Kältebeständigkeit bis zu - 1g° C. Gleichzeitig weist sie bei höheren Temperaturen noch ausgesprochen elastische Eigenschaften gegenüber der nach dem obengenannten Patent hergestellten Mantelmasse auf. Die Verbesserung der bekannten, oben beschriebenen mechanischen Eigenschaften eines reversibel thermoplastischen. Materials ist um so überraschender, als sie schon durch Zusätze von so geringen Mengen eines plastizierten Altgummis (i o %) erfolgt. Der gleiche Effekt ist nicht nur bei Massen beobachtet worden, die aus polymerisierten Derivaten der Acrylsäure für sich oder im Gemisch miteinander bestehen, sondern auch bei Polyacrylaten, die polymerisierte Vinyläther enthalten. Diese Massen enthalten dieselben Füllstoffe, wie sie in der Patentschrift 887 964 beschrieben sind.The mass described above has z. B. increased resistance to cold up to - 1g ° C. At the same time it shows at higher temperatures even more pronounced elastic properties compared to that produced according to the above-mentioned patent Sheath mass on. The improvement of the known, above-described mechanical Properties of a reversible thermoplastic. Materials is all the more surprising than they did by adding such small amounts of a plasticized old rubber (i o%) takes place. The same effect has not only been observed on masses, those from polymerized derivatives of acrylic acid alone or as a mixture with one another exist, but also with polyacrylates that contain polymerized vinyl ethers. These compositions contain the same fillers as those in patent specification 887,964 are described.
