Description

Der Patentinhaberin ist gestattet worden, die Erfinderbenennung nachzuholen Hülle für elektrische Leitungen und Kabel Es ist bekannt, hochpolymerisiertes Isobutylen zun- Isolation für elektrische Leitungen zu verwenden. Isobutylen hat hohes Isolationsvermögen, geringe di@elektrische Verluste, es ist sehr kältebeständig und zeigt nur geringe Alterungserscheinungen. Nachteilig ist, d@aß das nicht vulkanisierb.are hochpolymerisierte Isobutylen einen erheblichen kalten Fluß besitzt, d. h. auf dem Isobutylen lastende Gewichte prägen sich erheblich in das Isobutylen ein. In der praktischen Verwendung des Isobutylens als Leiterhülle bedeutet das, daß die Leiter sich in der Hülle .allmählich verlagern.The patent owner has been allowed to make up the inventor's designation Sheath for electrical wires and cables Highly polymerized isobutylene is known to use insulation for electrical lines. Isobutylene has high insulation properties, low di @ electrical losses, it is very cold-resistant and shows only minor Signs of aging. The disadvantage is that it is not vulcanizable and is highly polymerized Isobutylene has significant cold flux; H. on the isobutylene burdensome Weights are significantly imprinted on the isobutylene. In practical use of isobutylene as a conductor sheath, this means that the conductor is gradually moving into the sheath relocate.

Die nachteiligen Eigenschaften des hochpo'.ymerisierten Isobutylen,s können erfindungsgemäß durch Zusatz von vulkanisierbaren Polysulfiden im Verhältnis i : io und darüber bis i : i behoben werden. Polysulfide sind kautschukähnliche Kunststoffe, die ähnlich wie Kautschuk vulkanisierbar sind, große Wasser- und Ölbeständigkeit aufweisen, aber schlechte mechanische Eigenschaften, d. h. geringe Festigkeit und Dehnung, besitzen und auch nicht kältebeständig sind. In Verbindung mit hochpolymerisiertem Isobutylen machen sich jedoch die ungünstigen Eigenschaften der Polysulfide nicht bemerkbar. Die ,aus hochpolymerisiertem Isobutylen und Polysulfiden bestehenden Hüllen weisen überraschend günstige mechanische und elektrische Eigenschaften neben hoher Wasser-, Kälte- und ölbeständigkeit auf. Die Mischung beider Stoffe ergibt einen praktisch neuen Stoff mit sehr günstigen Eibenschaften.The disadvantageous properties of the highly polymerized isobutylene, s can according to the invention by adding vulcanizable polysulfides in proportion i: io and above until i: i are fixed. Polysulfides are similar to rubber Plastics that can be vulcanized in a similar way to rubber, have great water and oil resistance but have poor mechanical properties, i. H. low strength and Stretch, possess and are also not resistant to cold. In conjunction with highly polymerized However, the unfavorable properties of the polysulfides do not make isobutylene noticeable. The ones made up of highly polymerized isobutylene and polysulfides Casings also have surprisingly favorable mechanical and electrical properties high water, cold and oil resistance on. The mixture of both Substances results in a practically new substance with very favorable properties.

Die Verarbeitun,b der Polysulfide mit niedriger, mit dem hochpolymerisierten Isobutylen mit hoher Verarbeitungstemperatur in der Mischmaschine läßt sich dadurch ermöglichen, daß dem Isobutylen niedri-polymerisiertes Isobutylen in flüssigem Zustand zugesetzt wird.The processing of the polysulphides with lower, with the highly polymerized Isobutylene with a high processing temperature in the mixer can thereby allow the isobutylene to be low-polymerized isobutylene in a liquid state is added.

Hierdurch wird erreicht, daß das polymerisierte Isobutylen mit der für die Polysulfide erforderlichen niedrigen Temperatur verarbeitet werden. kann.This ensures that the polymerized isobutylene with the low temperature required for polysulphides to be processed. can.

Der aus der Mischung der genannten Stoffe gewonnene neue Stoff ist bei geringen Zusätzen von Polysulfiden nicht vulkanisierbar, dagegen läßt er sich bei größeren Zusätzen nahe der oberen Grenze vulkanisieren.The new substance obtained from the mixture of the substances mentioned is not vulcanizable with small additions of polysulphides, on the other hand it can be vulcanize near the upper limit in the case of larger additives.

,Nach :einem bevorzugten Mischungsverhältnis besteht die Hülle aus 4o 0 o hochpolymerisiertem Isobutylen, i 0'o niedrigpo.lymerisiertem Isobutylen, 30 «o Polysulfide, 5 0lo künstlichem Kautschuk, 5 @?" Beschleunigern verschiedener Art, i9 0 o Füllstoffen.According to: a preferred mixing ratio, the shell consists of 4o 0 o highly polymerized isobutylene, i 0'o low-polymerized isobutylene, 30 "o polysulphides, 5 0lo synthetic rubber, 5 @?" Accelerators of various Kind, i9 0 o fillers.
