Abstract

In known multilayered insulating foils having at least one plastic foil and at least a surface insulator made of fibrous material, the individual layers are interconnected with glue. The disadvantage of such a composite material is its sensitivity to hydrolysis. When the plastic foil of the electrically insulating foil is a hydrolysis-resistant thermoplastic foil and the multilayered insulating foil is produced under an appropriate pressure and at an appropriately high temperature, the thermoplastic foil acts as a hot-melt-type adhesive. The composite keeps therefore together even without glue and is hydrolysis-resistant.

Description

Die Erfindung betrifft eine Mehrschichtisolierfolie nach dem Oberbegriff des Anspruchs 1.The invention relates to a multilayer insulating film according to the Preamble of claim 1.

Aus dem Prospekt "Elektroisolierstoffe" der Firma KREMPEL ist auf Seite 3.1.8 eine Mehrschichtisolierfolie aus Polyesterfolie mit beidseitiger Aramidfaserauflage bekannt. Der Halt der Schichten wird mit Klebstoff erzielt.From the brochure "electrical insulation materials" from KREMPEL is on Page 3.1.8 a multilayer insulating film made of polyester film with known aramid fiber pad on both sides. The layers will stop achieved with glue.

Eine solche Mehrschichtisolierfolie dient bei Elektromotoren und Generatoren als Nutisolation in den Statoren und in den Rotoren (Läufer, Anker). Ferner eignet sie sich beispielsweise als Zwischenisolation bei Mehrschichtwicklungen und als Leiterisolierung. Sie ist während des Betriebs vielfachen Beanspruchungen ausgesetzt. Neben der mechanischen Beanspruchung infolge wechselnder Temperaturen und infolge der Bewegung des Rotors ist die Mehrschichtisolierfolie einer elektrischen Beanspruchung, einer thermischen und einer chemischen Beanspruchung ausgesetzt. Die chemische Beanspruchung wird hervorgerufen durch Imprägniermittel, die während der Herstellung aufgetragen werden und die Wärmeableitung begünstigen sollen, und eventuell durch eindringende Feuchtigkeit.Such a multilayer insulating film is used in electric motors and Generators as slot insulation in the stators and in the rotors (Runner, anchor). It is also suitable, for example, as Intermediate insulation in multi-layer windings and as conductor insulation. It is exposed to multiple stresses during operation. In addition to the mechanical stress due to changing temperatures and due to the movement of the rotor is the multilayer insulating film an electrical stress, a thermal and a exposed to chemical stress. The chemical stress will caused by impregnating agents that are used during manufacture should be applied and favor heat dissipation, and possibly due to penetrating moisture.

Allerdings sind auf Polyester- oder auf Polyimidbasis durch Verkleben hergestellte Isolierfolien hydrolyseempfindlich.However, are based on polyester or polyimide by gluing produced insulating foils sensitive to hydrolysis.

Der Erfindung liegt die Aufgabe zugrunde, eine Mehrschichtisolierfolie zu schaffen, die möglichst einfach ohne Verwendung von Klebstoff herstellbar ist und deren Schichten auch bei hoher Temperatur und bei Feuchtigkeitseinwirkung sich nicht lösen.The invention has for its object a To create multilayer insulating film that is as simple as possible without Use of adhesive can be produced and its layers also high temperature and when exposed to moisture.

Diese Aufgabe wird gelöst durch eine Mehrschichtisolierfolie gemäß Anspruch 1.This object is achieved by a multi-layer insulating film in accordance with Claim 1.

Vorteilhaft wirkt sich dabei aus, daß durch den Verbund die Eigenschaften der verschiedenen Einzelschichten in günstiger Weise kombiniert werden. So trägt die Kunststoffolie erheblich zur elektrischen Isolierung bei. Durch den Verbund, beispielsweise mit einem Gewebe oder einem Vlies, wird die Reißfestigkeit erhöht, die Falz- und Stanzbarkeit verbessert und die Mehrschichtisolierfolie vor schädlichen Einflüssen durch Oxydation und Hydrolyse geschützt. Außerdem hält eine Mehrschichtisolierfolie besser bei der Verarbeitung auftretenden mechanischen Einwirkungen stand. Der Verbund der Schichten wird allein durch Druck und durch Temperatur hergestellt; eine Verwendung von Klebstoff ist nicht erforderlich, da die Thermoplastfolie als Schmelzkleber wirkt. Es handelt sich um eine haltbare, hydrolysebeständige Mehrschichtisolierfolie, deren Schichten durch den guten Verbund dauerhaft zusammengehalten werden.The fact that the combination Properties of the various individual layers in a favorable way be combined. So the plastic film contributes significantly electrical insulation. Through the association, for example with  a fabric or a fleece, the tensile strength is increased, the Foldability and punchability improved and the multilayer insulating film before harmful influences protected by oxidation and hydrolysis. In addition, a multilayer insulation film holds better with the Processing mechanical influences. The The layers are bonded solely by pressure and temperature produced; the use of glue is not necessary because the thermoplastic film acts as a hot melt adhesive. It is about a durable, hydrolysis-resistant multilayer insulating film, the Layers are held together permanently by the good bond.

Vorzugsweise wird die Mehrschichtisolierfolie beidseitig durch eine Gewebeschicht aus Aramidfasern (aromatisches Polyamid) begrenzt; die Gewebeschicht kann besonders gut Imprägniermittel aufnehmen.The multilayer insulating film is preferably covered on both sides by a Fabric layer made of aramid fibers (aromatic polyamide) limited; the Fabric layer can absorb impregnating agents particularly well.

Weitere vorteilhafte Ausbildungen sind den Unteransprüchen zu entnehmen.Further advantageous developments are in the subclaims remove.

Die Erfindung wird im folgenden an Hand eines Ausführungsbeispiels, aus dem sich weitere Merkmale, Einzelheiten und Vorteile ergeben, näher beschrieben.The invention is described below using an exemplary embodiment, from which further features, details and advantages result, described in more detail.

Zwischen zwei Gewebeschichten aus Aramidfasern wird eine Schicht aus Polyetheretherketon eingefügt. Diese drei Schichten werden unter eine beheizte Presse gelegt. Bei hohem Druck und bei hoher Temperatur entsteht in der Presse ein fester Verbund der drei Schichten, da das Polyetheretherketon als Schmelzkleber wirkt. Das Gewebe aus Aramidfasern, das auf der Ober- und auf der Unterseite der Mehrschichtisolierfolie vorhanden ist, kann gut Imprägniermittel aufnehmen. Das Imprägniermittel erhöht die Wärmeleitfähigkeit, was sich günstig auswirkt, wenn die Mehrschichtisolierfolie in Nuten in einem Elektromotor oder in einem Generator eingefügt wird.A layer is made between two layers of aramid fiber Polyetheretherketone inserted. These three layers are under one heated press. At high pressure and at high temperature a solid bond of the three layers is created in the press, because that Polyether ether ketone acts as a hot melt adhesive. The tissue out Aramid fibers on the top and bottom of the Multilayer insulation film is present, can be good impregnant record, tape. The impregnating agent increases the thermal conductivity, what has a favorable effect if the multilayer insulating film in grooves in an electric motor or in a generator.
