Description
Die Erfindung liegt auf dem Gebiet der elektrischen Kabel und Leitungen und ist bei der Herstellung einer vernetzbaren Iso liermischung auf EPR-Basis anzuwenden.The invention is in the field of electrical cables and Lines and is in the process of producing a cross-linkable iso Applying mixture based on EPR.
Als Werkstoff für die Isolierung elektrischer Kabel und Lei tungen werden häufig Olefin-Polymere (wie z. B. Polyethylen, PE) Oder Olefin-Copolymere (wie z. B. Ehylen-Propylen-Kaut schuk, EPR) und Abmischungen aus diesen Kunststoffen ver wendet. Beispielsweise ist für kunststoffisolierte Stark stromkabel des Mittelspannungsbereiches eine vernetzbare Iso liermischung bekannt, die aus PE und EPR in Anteilen zwischen etwa 80 : 20 und 20 : 80 besteht. Als EPR-Anteil wird ein kri stallines Ethylen-Propylen-Copolymerisat mit 78% Ethylenge halt verwendet. Der Anteil an PE erhöht die mechanische Fe stigkeit und Härte der Mischung. Diese Mischung enthält keine Weichmacher und im wesentlichen auch keinen Füllstoff (DE 31 11 524 A1).As a material for the insulation of electrical cables and lei olefin polymers (such as polyethylene, PE) or olefin copolymers (such as ethylene-propylene chew schuk, EPR) and mixtures of these plastics ver turns. For example, Stark is for plastic insulated Power cable of the medium voltage range a networkable iso lier mixture known from PE and EPR in proportions between about 80:20 and 20:80. A kri stalline ethylene-propylene copolymer with 78% ethylene just used. The proportion of PE increases the mechanical Fe strength and hardness of the mixture. This mixture does not contain any Plasticizer and essentially no filler (DE 31 11 524 A1).
Als Umhüllung für elektrische Kabel und Leitungen ist weiter hin eine unvulkanisierte Mischung auf der Basis eines Ethy len-Propylen-Copolymerisates mit einem kleineren Anteil eines Polyethylen bekannt, die mit größeren Anteilen einer Gleitmit telkombination und eines Füllstoffes versehen ist (DE 23 05 444 B1).As a covering for electrical cables and wires is further towards an unvulcanized mixture based on an Ethy len-propylene copolymer with a smaller proportion of one Polyethylene known with a larger proportion of a glide telkombination and a filler is provided (DE 23 05 444 B1).
Im übrigen ist es auch üblich, vernetzbare Isoliermischungen
auf EPR-Basis zu verwenden, die keine weitere Polymerkompo
nente, dafür aber gewisse Weichmacheranteile enthalten. Bei
den verwendeten EPR-Sorten kann es sich sowohl um amorphe Ty
pen (Ethylengehalt kleiner 65%, Anwendungsbereich: elektri
sche Isolierung im Niederspannungsbereich) als auch um kri
stalline Typen (Ethylengehalt größer 65%, Anwendungsbereich:
Hochspannungs-Elektrokabelisolierung) handeln. Die Moone-Vis
kosität dieser EPR-Typen liegt zwischen 20 und 70. Bei ei
nigen Anwendungen wird eine besonders flexible Isolation ge
wünscht. Diese hohe Flexibilität ist bisher nur durch den Zu
satz von Weichmachern erreichbar (Produktinformation der Fa.
DuPont). - Der Nachteil einer mit Weichmachern angereicherten
Isoliermischung auf EPR-Basis liegt darin, daß die für bei
spielsweise Hochspannungsleitungen notwendige Gleich- bzw.
Wechselspannungsfestigkeit nicht mit ausreichender Sicherheit
erreichbar ist. Bei hohen elektrischen Anforderungen an die
Isoliermischungen ist es daher üblich, die Anforderungen be
züglich der Flexibilität herabzusetzen.In addition, it is also common to use crosslinkable insulating mixtures based on EPR, which do not contain any further polymer components, but do contain certain plasticizer components. The EPR grades used can be both amorphous types (ethylene content less than 65%, application area: electrical insulation in the low-voltage range) and crystalline types (ethylene content greater than 65%, application area:
High-voltage electrical cable insulation). The Moone viscosity of these EPR types is between 20 and 70. For some applications, a particularly flexible insulation is desired. This high degree of flexibility has so far only been achieved by adding plasticizers (product information from DuPont). - The disadvantage of an EPR-based insulating mixture enriched with plasticizers is that the DC or AC voltage strength required for example in high-voltage lines cannot be achieved with sufficient certainty. In the case of high electrical requirements for the insulation mixtures, it is therefore customary to reduce the requirements with regard to flexibility.
Ausgehend von einer vernetzbaren, weichmacherfreien Isolier mischung für elektrische Kabel und Leitungen auf der Basis eines Ehtylen-Propylen-Kautschuks mit einem kleineren Anteil eines Polyethylens liegt der Erfindung die Aufgabe zugrunde, die Mischung so zu modifizieren, daß ein flexibler Werkstoff entsteht, der auch hochspannungstechnischen Anforderungen ge nügt.Starting from a cross-linkable, plasticizer-free insulation mixture for electrical cables and wires on the base a ethylene-propylene rubber with a smaller proportion of a polyethylene, the invention is based on the object to modify the mixture so that a flexible material arises, which also ge high-voltage requirements is enough.
Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, daß die Mischung die folgenden Komponenten enthält: AufTo achieve this object, the invention provides that the mixture contains the following components: On
- 1) 100 Gew.-Teile eines amorphen Ehtylen-Propylen-Co- oder Terpolymerisats (EPM oder EPDM) mit einem Ehtylengehalt von 55 bis 65%, dessen Mooney-Viskosität kleiner 25 ist,1) 100 parts by weight of an amorphous ethylene-propylene-Co or Terpolymers (EPM or EPDM) with an ethylene content from 55 to 65%, whose Mooney viscosity is less than 25,
- 2) 5 bis 20 Gew.-Teile eines Polyethylens mit einer Dichte kleiner 0,92 g/cm³,2) 5 to 20 parts by weight of a density polyethylene less than 0.92 g / cm³,
- 3) 50 bis 150 Gew.-Teile eines Füllstoffes in Form eines kalzinierten Kaolins und3) 50 to 150 parts by weight of a filler in the form of a calcined kaolin and
- 4) etwa 1 bis 3 Gew.-Teile eines Vinylsilans.4) about 1 to 3 parts by weight of a vinyl silane.
Durch die Verwendung eines EPR-Kautschucks mit einem im obe ren Bereich des amorphen Zustandes liegenden Ethylengehalt und durch Zusatz einer gewissen Menge eines Polyethylens/PE geringer Dichte wird der Werkstoff auch ohne Zusatz von Weichmachern hinreichend flexibel. Der Anteil an PE kann da bei innerhalb des angegebenen Bereiches variiert und dadurch die gewünschte Härte (Shore A) eingestellt werden. - Die ge ringe Viskosität des verwendeten EPR-Kautschucks erleichtert das Verarbeiten im Extruder. Der Einsatz dieser speziellen EPR-Type, die im Handel beispielsweise unter dem Warenzeichen "Nordel 2522" der Fa. DuPont erhältlich ist, ermöglicht auch die Verwendung von calciniertem Kaolin als Füllstoff, ohne daß dadurch die geforderten elektrischen Eigenschaften unter schritten werden. Zur Verbesserung der Feuchteresistenz und der Zugfestigkeit wird der Mischung weiterhin ein Vinylsilan zugegeben. Alternativ dazu kann auch ein silanisiertes Kaolin als Füllstoff verwendet werden.By using an EPR rubber with one in the above ren range of the amorphous state ethylene content and by adding a certain amount of a polyethylene / PE The material becomes low density even without the addition of Plasticizers sufficiently flexible. The proportion of PE can be there varies within the specified range and thereby the desired hardness (Shore A) can be set. - The ge rings viscosity of the EPR rubber used relieved processing in the extruder. The use of this special EPR-Type, which is commercially available, for example, under the trademark "Nordel 2522" from DuPont is also possible the use of calcined kaolin as a filler without that thereby the required electrical properties under be paced. To improve moisture resistance and the tensile strength of the mixture continues to be a vinyl silane admitted. Alternatively, a silanized kaolin can be used can be used as filler.
Flexible elektrische Leitungen, wie sie beispielsweise als Hochspannungsleitungen für Röntgengeräte benötigt werden und deren Isolierung aus einer gemäß der Erfindung hergestellten Abmischung bestehen, weisen eine hohe Lehnigkeit von größer 650 auf (d. h. ein 60 cm langes Leitungsstück biegt sich durch das eigene Gewicht um einen Winkel größer 65° durch). Die nach VDE 0472 § 603 Prüfart L gemessene statische Flexibili tät liegt innerhalb des für solche Leitungen vorgesehenen Be reiches. Bei der Prüfung dieser Eigenschaft wird ein Lei tungsstück von 3 m Länge mit dem einen Ende an einer Schiene befestigt; das andere Ende wird - von einem Minimalabstand von 20 cm ausgehend - nach außen bewegt, bis sich eine an beiden Leitungsenden senkrecht verlaufende Schlaufe bildet. Der Abstand der beiden senkrecht verlaufenden Schlaufenenden auf der Schiene ist bei erfindungsgemäß isolierten Leitungen kleiner als 55 cm und liegt damit innerhalb des geforderten Bereiches. Flexible electrical lines, such as as High voltage lines are needed for X-ray machines and their isolation from a manufactured according to the invention Mixing exist, have a high leanness of greater 650 on (i.e. a 60 cm length of pipe bends your own weight through an angle greater than 65 °). The Static flexibility measured according to VDE 0472 § 603 test type L. act is within the intended for such lines Be rich. When examining this property, a lei piece of 3 m long with one end on a rail attached; the other end is - from a minimum distance starting from 20 cm - moved outwards until one comes on forms a vertical loop at both ends of the cable. The distance between the two vertical loop ends is on the rail in lines insulated according to the invention smaller than 55 cm and is therefore within the required Area.
