Description

Schichtpreßstoff auf Polyäthylen-Terephthalsäureester-Basis Die Erfindung betrifft einen Schichtstoff, der durch Tränken eines Gewebes oder von Fasern mit einer härtbaren Kunststofflösung und Behandeln mehrerer so hergestellter Lagen mittels Druck und Wärme hergestellt und als Ausgangsmaterial zur Verwendung für elektrotechnische Zwecke, insbesondere zum Aufbau von Isolierteilen von elektrischen Schaltern, dient.Laminate based on polyethylene terephthalic acid ester The invention relates to a laminate that is made by impregnating a fabric or fibers with a hardenable plastic solution and treating several layers produced in this way by means of Pressure and heat produced and used as a raw material for electrotechnical Purposes, in particular for the construction of insulating parts of electrical switches.

Es sind bereits derartige Schichtpreßstoffe aus Papierschnitzeln, Faden- und Gewebematerial, aus Baumwolle, Zellulose oder ähnlichen abgewandelten Naturstoffen, mit Phenolaldehyd und sonstigen härtbaren Kunstharzen bekannt. Diese zeichnen sich durch geringes Gewicht aus und haben sich auf weiten Gebieten der Elektrotechnik durchgesetzt. Von Nachteil jedoch sind deren Feuchtigkeitsempfindlichkeit, geringe statische Bruchlast, Schlagfestigkeit und Abriebfestigkeit.There are already such laminates made of shredded paper, Thread and fabric material, modified from cotton, cellulose or similar Natural substances, with phenol aldehyde and other curable synthetic resins known. These are characterized by their low weight and have proven themselves in large areas of the Electrical engineering prevailed. However, their sensitivity to moisture is a disadvantage, low static breaking load, impact resistance and abrasion resistance.

Es wurde nun gefunden, daß letztere Eigenschaften verbessert werden, wenn. man Fäden oder ein Gewebe von Polyäthylen-Terephthalsäureestern als Trägermaterial verwendet. Ein daraus hergestellter Schichtpreßstoff zeigt größere Bruch-, Schlag- und Zerreißfestigkeit als die bisherigen aus Zellulose-, Baumwoll-oder Naturstoffen hergestellten Schichtpreßstoffe.It has now been found that the latter properties are improved, if. threads or a fabric of polyethylene terephthalic acid esters are used as the carrier material used. A laminate made from it shows greater breakage, impact and tensile strength than the previous ones made of cellulose, cotton or natural materials manufactured laminates.

Gegenstand der Erfindung ist die Verwendung von Schichtpreßstoffen aus mit Kunstharz verbundenen Terephthalsäureestern in Form von Faser- oder Gewebematerial zum Aufbau von Isolierteilen von elektrischen Schaltern, wie z. B. Schaltkammerwandungen, Isolierstangen od. dgl.The invention relates to the use of laminates from terephthalic acid esters combined with synthetic resin in the form of fiber or fabric material for the construction of insulating parts of electrical switches, such as. B. switching chamber walls, Insulating rods or the like.

Diese Schichtpreßstoffe zeigen sehr gute thermische Eigenschaften, gute Biegefestigkeit sowie eine sehr geringe, praktisch vernachlässigbare Wasseraufnahme und Quellung und sind gegen die üblichen Lösungsmittel beständig. Sie sind besonders zur Verwendung im Freien und, dank ihrer Säurebeständigkeit, in mit Säuredämpfen verseuchten Räumen geeignet.These laminates show very good thermal properties, good flexural strength and very low, practically negligible water absorption and swelling and are resistant to the usual solvents. You are special for use outdoors and, thanks to its acid resistance, in with acid vapors suitable for contaminated rooms.

Dank der hervorragenden Isoliereigenschaften, der geringen Wasseraufnahme und der hohen mechanischen Festigkeit eignet sich dieses Material daher zum Aufbau von Isolierteilen von elektrischen Schaltern, z. B. auch zur Halterung in Form von Rohren, als Wandmaterial zur Auskleidung von Schaltkammern.Thanks to the excellent insulating properties and the low water absorption and the high mechanical strength, this material is therefore suitable for construction of insulating parts of electrical switches, e.g. B. also for mounting in the form of Pipes, as wall material for lining switching chambers.

Diese Schichtpreßstoffe können als Isolierteile für elektrische Schalter in verschiedenen Formen, wie Platten, Stangen., Röhren usw., hergestellt und nach bekannten Methoden zu Formkörpern beliebiger Gestalt weiterverarbeitet werden.These laminates can be used as insulating parts for electrical switches in various shapes, such as plates, rods., tubes, etc., made and according to known methods can be further processed to moldings of any shape.

Es war schon bekannt, zum Isolieren elektrischer Leiter, wie z. B. Kabeldrähten, Terephthalsäureester in Form von Faden- oder Filmmaterial zu verwenden sowie Schichtstoffe daraus herzustellen. Jedoch hatte man noch nicht erkannt, daß sich aus Terephthalsäureestern hergestellte Schichtpreßstoffe, ein aus diesem Material hergestelltes sogenanntes Hart gewebe, als Isolierteile für elektrische Schalter besonders vorteilhaft verwenden lassen, da sie überraschenderweise sowohl gute elektrische Eigenschaften, auch bei erhöhter Temperatur, aufweisen als auch außergewöhnliche mechanische Eigenschaften, insbesondere eine hohe Bruchfestigkeit und Schlagfestigkeit, besitzen. Wegen dieser Eigenschaften sind sie speziell zur Verwendung als Isolierteile von elektrischen Schaltern geeignet.It was already known to insulate electrical conductors such. B. To use cable wires, terephthalic acid ester in the form of thread or film material as well as producing laminates from them. However, it was not yet recognized that Laminates made from terephthalic acid esters, one from this material Manufactured so-called hard tissue, as insulating parts for electrical switches Can be used particularly advantageously, surprisingly because they are both good electrical Properties, even at elevated temperatures, are also exceptional mechanical properties, especially high breaking strength and impact resistance, own. Because of these properties, they are specially designed for use as insulating parts suitable for electrical switches.

Die Leistungsfähigkeit von Schaltern kann dadurch wesentlich gesteigert werden gegenüber Schaltern, bei welchen Hartgewebe auf Zellulosebasis oder ähnlichem Material zur Isolation verwendet wird.This can significantly increase the performance of switches are compared to switches in which hard tissue based on cellulose or the like Material is used for insulation.
