Die Erfindung bezieht sich auf eine Füllmasse, insbesondere zum Füllen von Kabelseelen, die aus einem Petrolat, einem hochmolekularen Öl, einem hochmolekularen Polymer und Verarbeitungshilfsmittel(n) besteht.The invention relates to a filling compound, especially for filling cable cores from a Petrolat, a high molecular oil, one high molecular polymer and processing aids consists.

Aus der US-PS 37 75 548 ist eine Füllmasse bekannt, die zu ca. 80 Gewichtsprozent aus Petrolat, zu ca. 10 Gewichtsprozent aus Polyisobutylen und zu ca. 10 Gewichtsprozent aus Polyäthylen und/oder Polybuten-1 besteht.From US-PS 37 75 548 a filling compound is known about 80 percent by weight from petrolatum, about 10 Percentage by weight of polyisobutylene and about 10 Percentage by weight of polyethylene and / or polybutene-1 consists.

Derartige Füllmassen haben den Zweck, die Kabelseele längswasserdicht zu machen. Gemäß den Anforderungen der Deutschen Bundespost müssen die Füllmassen in einem Temperaturbereich von -5°C bis +70°C einsetzbar sein. Für Kabel, die in arktischen oder tropischen Ländern betrieben werden, sind diese Füllmassen nicht geeignet.Such fillers have the purpose of the cable core to make it longitudinally watertight. According to the requirements of German federal post office must fill the masses in one Temperature range from -5 ° C to + 70 ° C can be used. For cables used in arctic or tropical countries these fillers are not suitable.

Der Erfindung liegt die Aufgabe zugrunde, preiswerte Füllmassen anzugeben, die in einem breiteren Temperaturbereich einsetzbar sind. The invention has for its object inexpensive Fill masses to be specified in a wider range Temperature range can be used.  

Die Lösung dieser Aufgabe ist durch die im Hauptanspruch genannte Füllmasse gegeben. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten.The solution to this problem is through the main claim given filler. Advantageous configurations are contained in the subclaims.

Die neuen Füllmassen sind in einem Temperaturbereich vonThe new filling compounds are in a temperature range of

  • -35°C bis +95°C einsetzbar. Sie weisen auch unter Scher- und Druckbeanspruchung einen hohen Tropfpunkt auf und sind trotzdem leicht, auch kalt, verarbeitbar. Sie besitzen gute elektrische Eigenschaften und eine gute Verträglichkeit mit den bei Kabeln üblicherweise verwendeten Materialien.-35 ° C to + 95 ° C applicable. They also show under shear and pressure load have a high dropping point on and are still light, also cold, processable. they have good electrical properties and good ones Compatibility with the usual for cables used materials.

Die neuen Füllmassen bestehen aus
50 bis 80 Gewichtsteilen eines weichen Petrolats,
5 bis 40 Gewichtsteilen eines hochmolekularen Öls,
1 bis 8 Gewichtsteilen eines hochmolekularen Polymers und
0,5 bis 7 Gewichtsteilen Verarbeitungshilfsmittel.
Das weiche Petrolat besteht aus einem raffinierten, paraffinischen Öl mit Petroleum-Harz, beispielsweise TCV 70 der Firma Witco. Das hochmolekulare Öl besteht vorzugsweise aus Polyisobutylen mittleren Molekulargewichts mit mikrokristallinen Wachsen, beispielsweise Naptel der Firma BP-Chemie. Als Polymer ist insbesonder Polyäthylen- oder Polypropylen in Pulverform geeignet. Als Verarbeitungshilfsmittel kommt Stearinsäure und/oder ein Gleitmittel in Betracht.The new filling compounds consist of
50 to 80 parts by weight of a soft petrolatum,
5 to 40 parts by weight of a high-molecular oil,
1 to 8 parts by weight of a high molecular weight polymer and
0.5 to 7 parts by weight of processing aids.
The soft petrolat consists of a refined, paraffinic oil with petroleum resin, for example TCV 70 from Witco. The high molecular weight oil preferably consists of medium molecular weight polyisobutylene with microcrystalline waxes, for example Naptel from BP-Chemie. In particular, polyethylene or polypropylene in powder form is suitable as the polymer. Stearic acid and / or a lubricant can be used as processing aids.

Ein bevorzugtes Ausführungsbeispiel hat folgende Zusammensetzung:
60 Gewichtsteile weiches Petrolat,
35 Gewichtsteile Polyisobutylen von mittlerem Molekulargewicht mit mikrokristallinen Wachsen
5 Gewichtsteile Polyäthylenpulver einer Dichte von 0,94 g/cm3 und
0,5 Gewichtsteile Stearinsäure. A preferred embodiment has the following composition:
60 parts by weight of soft petrolatum,
35 parts by weight of medium molecular weight polyisobutylene with microcrystalline waxes

0.5 parts by weight of stearic acid.

Die einzige Figur zeigt ein gefülltes optisch-elektrisches Kabel im Querschnitt. Es weist ein zentrales Stützelement 6 auf, um das sechs Bündeladern 1 und ein Kupfer-Zweier 2 angeordnet sind. Darüber befindet sich eine Seelenbewicklung 5. Die Zwischenräume zwischen den obengenannten Elementen sind mit der Füllmasse 3 gefüllt. Dadurch ist die Kabelseele längswasserdicht. Über der Seelenbewicklung 5 befindet sich ein Kabelmantel 4, beispielsweise ein Schichtenmantel mit Zugentlastungselementen.The single figure shows a filled optical-electrical cable in cross section. It has a central support element 6 , around which six loose tubes 1 and a copper pair 2 are arranged. There is a soul wrapping 5 above it. The spaces between the above-mentioned elements are filled with the filling compound 3 . This makes the cable core longitudinally watertight. A cable sheath 4 , for example a layer sheath with strain relief elements, is located above the core winding 5 .
