Description
Kabelisolierung und -ummantelung aus Polyvinylchlorid oder polyvinylchloridhaltigen Mischpolymerisaten und Weichmachern Es ist bekannt, daß sich aus Vinylhalogeniden durch Polymerisation Erzeugnisse herstellen lassen, die homogene Massen mit thermoplastischen Eigenschaften darstellen. Um die Verarbeitbarkeit dieser Massen zu verbessern, wurden Weichmacher zugesetzt, wodurch jedoch mit steigenden Weichmachergehalt die dielektrischen Eigenschaften des Kunststoffes verschlechtert werden, während mit sinkendem Weichmachergehalt mechanische Eigenschaften, wie Biegsamkeit, Geschmeidigkeit eine Herabsetzung erleiden.Cable insulation and sheathing made from polyvinyl chloride or polyvinyl chloride-containing copolymers and plasticizers. It is known that products which are homogeneous masses with thermoplastic properties can be produced from vinyl halides by polymerization. In order to improve the processability of these compositions, plasticizers have been added, but the dielectric properties of the plastic material are degraded whereby with increasing plasticizer content, while with decreasing plasticizer content mechanical properties such as flexibility, smoothness suffer a reduction.
Es besteht daher bei der Verwendung von Polyvinylchlorid oder von Mischpodymeirisaten, die Polyvinylchlorid zum wesentlichen Teil enthalten, für Kabelummantelungen das Bestreben, den Weichmacherzusatz zu verringern, ohne die mechanischen Eigenschaften nachteilig zu verändern.There is therefore the use of polyvinyl chloride or of Mixed body products, which mainly contain polyvinyl chloride, for cable sheathing the endeavor to reduce the addition of plasticizers without compromising the mechanical properties to change disadvantageously.
Gemäß der Erfindung wird dies durch Zusätze von PoIymerisaten aus Acrylsäurebutylester erreicht, welche die Fähigkeit haben, die dielektrischen Eigenschaften nicht zu verschlechtern, mechanisch aber insbesondere bei tiefen Temperaturen eine Verbesserung herberiführen. Diese Zusätze werden dem PolyvinyIchlorid bzw. po@lyvinylchloridhaltigen Polymerisaten zugemischt. Der Zusatt -beträgt gemäß der Erfindung I bis 5 Gewichtsprozent des Pölyvinylhalogenids bzw. des Mischpolymerisates, welch letzteres beispielsweise neben 8o Gewichtsteilen Polyvinylchlorid 2o Gewichtsteile Po-lyacrylsäureätliylester enthalten kann.According to the invention, this is done by adding polymers Acrylic acid butyl ester achieved, which have the ability to have the dielectric properties not to deteriorate, mechanically but especially at low temperatures one Bring about improvement. These additives are the polyvinyl chloride or polyvinyl chloride-containing Added polymers. The addition - amounts according to the invention I to 5 percent by weight of the polyvinyl halide or the copolymer, which the latter, for example, in addition to 80 parts by weight of polyvinyl chloride, 2o parts by weight May contain polyacrylic acid ethyl ester.
Die Verwendung von Polyisobuty len als Weichmacher für Polyvinylchlorid ist bereits bekannt, doch ist die Herstellung und insbesondere die Verarbeitung solcher Mischungen schwierig, wodurch sich die Anwendung dieser Mischungen in der Praxis verbietet. Ferner ist es bekannt, monomeren A crylsäurebutylester gemeinsam mit anderen Acrylsäureestern oder mit Vinylelilorid zu polymerisieren, jedoch gestatten solche Mischpolymerisate nicht die Veränderung des Mengenverhältnisses nach ihrer Fertigstellung.The use of polyisobutylene as a plasticizer for polyvinyl chloride is already known, but the production and especially the processing Such mixtures difficult, which makes the application of these mixtures in the Practice forbids. It is also known to share monomeric butyl acrylate polymerize with other acrylic acid esters or with vinylelilorid, but allow such copolymers do not change the proportions according to their Completion.
Die Herstellung der Masse gemäß der Erfindung kann durch Vermischen des oder der Polymerisate mit dem Palyacrylsäurebutylester auf der Mischwalze oder in Knetinaschinen unter Zuhilfenahme erhöhter Temperaturen und/oder nötigenfalls auch geringer Mengen von Lösungsmitteln erfolgen. Das Lösungsmittel bewirkt eine erhöhte Plastizität zu Beginn des Mischvorganges und verflüchtigt sich bei der Weiterverarbeitung.The composition according to the invention can be prepared by mixing of the polymer (s) with the butyl acrylate on the mixing roller or in kneading machines with the aid of elevated temperatures and / or if necessary small amounts of solvents can also be used. The solvent causes a increased plasticity at the beginning of the mixing process and evaporates during further processing.
Die Zusammensetzung der Mischung gemäß der Erfindung kann wie folgt
sein: 6o Gewichtsteile Polyvinylchlorid,
Es zeigt sich also, daß durch den erfindungsgemäßen Zusatz die Kälteschlagfertigkeit von Kabelisolierungen und -ummantelunbgen erhöht wird und Beschädigungen an den mit dieser Masse umhüllten Leitern oder Kabeln unter den vorerwähnten Bedingungen nicht auftreten.It can therefore be seen that the additive according to the invention increases the ability to hit the cold of cable insulation and sheathing is increased and damage to the conductors or cables covered with this mass under the aforementioned conditions do not occur.
