Description
Die vorliegende Erfindung betrifft ein verbessertes Verfahren zur Herstellung von isolierten Wickeldrähten durch Extrusion von Thermoplasten.The present invention relates to an improved method for producing insulated winding wires by extrusion of thermoplastics.
Lackisolierte Wickeldrähte, sogenannte "Lackdrähte" sind in der Deutschen Norm DIN 46435 von April 1977 genau charakterisiert. Sie kommen in großem Umfang im Elektromaschinenbau, Transformatorenbau und in der Elektronik zum Einsatz.Enamel-insulated winding wires, so-called "enamelled wires", are precisely characterized in the German standard DIN 46435 from April 1977. They are used on a large scale in electrical engineering, transformer construction and electronics.
Das Lietermetall, vorzugsweise Kupfer oder Aluminium, ist mit einer dünnen, jedoch mechanisch und thermisch äußerst widerstandsfähigen Kunstharzlackschicht isoliert.The supply metal, preferably copper or aluminum, is insulated with a thin, but mechanically and thermally extremely resistant synthetic resin lacquer layer.
Die Herstellung derartiger Lackdrähte erfolgt auf Drahtlackiermaschinen durch mehrfaches kontinuierliches Auftragen eines Drahtlackes auf den Metalldraht. Im Hinblick auf die Schädlichkeit der in dem Drahtlack enthaltenen Lösungsmittel und auf die sich daraus ergebenden Umweltprobleme werden zur Drahtlackierung auch schon Drahtlack-Dispersionen und wäßrige Lösungen von Drahtlackharzen sowie auch Harzschmelzen eingesetzt.Such enamelled wires are produced on wire enamelling machines by repeatedly applying an enamelled wire enamel to the metal wire. With regard to the harmfulness of the solvents contained in the wire enamel and to the environmental problems resulting therefrom, wire enamel dispersions and aqueous solutions of wire enamel resins as well as resin melts are already used for wire enamelling.
Alle diese bekannten Verfahren sind durch die damit erreichbaren verhältnismä;ßig niedrigen Absugsgeschwindigkeiten jedoch recht arbeits- und zeitaufwendig.All of these known methods, however, are quite laborious and time-consuming due to the relatively low suction speeds that can be achieved with them.
Aus der Kabelindustrie ist seit langem die Extrusion von Thermoplasten zur dickwandigen Ummantelung elektrischer Leiterbündel sowie zur Herstellung von Leitungsdrähten bekannt.The extrusion of thermoplastics for thick-walled sheathing of electrical conductor bundles and for the production of conductor wires has long been known from the cable industry.
So werden in der DE-A-26 35 895, Beispiel 4, ein Reaktionsprodukt aus p-Phenoxybenzoylchlorid und Biphenyl, sowie in der FR-A-1 548 761 Polyätherketone mit substituierten Phenolresten oder Aryläthersulfonpolymere hierfür beschrieben.S o A-1 548 761 FR-polyetherketones with substituted phenol moieties or Aryläthersulfonpolymere described for this purpose in DE-A-26 35 895, Example 4, a reaction product of p-phenoxybenzoyl chloride, and biphenyl, as well as in the.
In der DE-A-26 38 763 wird ein Verfahren zur Herstellung von lackisolierten Wickeldrähten durch Extrusion von teilkristallinen thermoplastischen Polykondensaten mit Kristallitschmelzpunkten oberhalb 170°C, vorzugsweise oberhalb 250°C, beschrieben, bei dem derart dünne Isolierschichten, wie sie laut DIN 46435 gefordert werden, erhalten werden können.DE-A-26 38 763 describes a process for the production of enamel-insulated winding wires by extrusion of partially crystalline thermoplastic polycondensates with crystallite melting points above 170 ° C., preferably above 250 ° C., in which thin insulating layers, as required by DIN 46435 will be preserved.
Außer den verschiedenen linearen Polyestern und Polyamiden werden im Text Polymere mit kettenständigen Schwefelatomen, wie z.B. Polyphenylensulfid, genannt. In den Beispielen werden die Extrusionsbedingungen für Polyäthylenterephthalat, 6,6-Polyamid sowie Polyphenylensulfid und die Eigenschaften der damit erhaltenen Wickeldrähte beschrieben.In addition to the various linear polyesters and polyamides, polymers with chain sulfur atoms, e.g. Called polyphenylene sulfide. The examples describe the extrusion conditions for polyethylene terephthalate, 6,6-polyamide and polyphenylene sulfide and the properties of the winding wires obtained therewith.
Alle diese mit den genannten Thermoplasten beschichteten Wickeldrähte haben den Nachteil, daß ihre Erweichungstemperaturen (nach DIN 46453) weit unter 300°C liegen, also den gestiegenen Anforderungen nicht entsprechen und auch, daß die Wärmeschockwerte teilweise unbefriedigend sind; außerdem wiesen die Lackdrähte eine für die Ansprüche der modernen Motorenwickeltechnik zu niedrige Oberflächenhärte auf.All of these winding wires coated with the aforementioned thermoplastics have the disadvantage that their softening temperatures (according to DIN 46453) are far below 300 ° C, ie they do not meet the increased requirements and also that the thermal shock values are in part unsatisfactory; the enamelled wires also had a surface hardness that was too low for the requirements of modern motor winding technology.
Es wurde nun überraschenderweise gefunden, daß spezielle teilkristalline thermoplastische Polykondensate mit Kristallitschmelzpunkten oberhalb 250°C hier entscheidende Verbesserungen bringen.It has now surprisingly been found that special semi-crystalline thermoplastic polycondensates with crystallite melting points above 250 ° C. bring decisive improvements here.
Gegenstand der Erfindung ist also eine Verwendung von aromatischen Polyätherketonen mit wiederkehrenden Einheiten der Formel
Es war in keiner Weise vorauszusehen und ist daher völlig überraschend, daß mit aromatischen Polyätherketonen, d. i. mit Thermoplasten, beschichtete Wickeldrähte eine Erweichungstemperatur von weit über 300°C sowie eine Oberflächenhärte von 2-3 H besitzen, wie sie sonst nur Wickeldrähte mit Duroplastbeschichtungen erreichen.It was in no way foreseeable and is therefore completely surprising that with aromatic polyether ketones, i.e. i. with thermoplastic, coated winding wires have a softening temperature of well over 300 ° C and a surface hardness of 2-3 H, which is normally only achieved with winding wires with thermoset coatings.
Im Vergleich zu den Werten bei den übrigen Thermoplasten ist außerdem der Wärmeschockwert der mit Poiyätherketonüberzüger isolierten Wickeldrähte überraschenderweise stark verbessert.In comparison to the values for the other thermoplastics, the thermal shock value of the winding wires insulated with polyether ketone coating is surprisingly greatly improved.
