Description
DEUTSCHESGERMAN
Während Lackaufträge auf Kupfer, die keinen höheren Temperaturen ausgesetzt sind, meist gut haften, neigen höheren Temperaturen, beispielsweise mehr als 120° C, insbesondere 150° C, ausgesetzte Aufträge aus hitzebeständigen Lacken, beispielsweise solche auf siliciumoTganischer Basis, zum Abplatzen, da die bei der Wärmebehandlung entstehende Kupferoxydschicht nur sehr schlecht am Kupfer haftet und sich deshalb leicht mit dem Lackauftrag abziehen läßt. Man hat deshalb schon auf Kupferleiter, die mit temperaturbeständigem Lacken isoliert sind, Zwischenschichten aus Kadmium oder Nickel oder Edelmetallen, wie Silber, aufgebracht. Die Haftfestigkeit der Laeke ist bei Silber und Nickel zwar immer noch bedeutend besser als bei Kupfer, jedoch ist dies allein nicht ausschlaggebend. Es kommt nämlich hinzu, daß je nach dem Metall der Lackauftrag längere oder kürzere Zeit zum Duircbhärten braucht. Diese Erscheinung ist wohl darin begründet, daß die betreffenden Metalle oder Metalloxyde verschieden stark die Härtung beschleunigen oder verzögern. Dies kann durch ihre chemischen Eigenschaften bedingt sein oder durch die Fähigkeit, sich mehr oder weniger gut im Lackstoff zu lösen oder in diesen zu diffundieren. Versuche haben gezeigt, daß bei Kupfer die Härtezeit verhältnismäßig· kurz ist. Bei Nickel, Silber, Aluminium ist sie aber fast viermal so lang. Kadmium oder Zinnüberzüge als Zwischenschicht haben den weiteren Nachteil, daß sie in den Kupferleiter diffundieren und dadurch dessen Leitfähigkeit beeinträchtigen.While paint applications on copper that are not exposed to higher temperatures usually adhere well, Tend to higher temperatures, for example more than 120 ° C, especially 150 ° C, exposed applications made of heat-resistant lacquers, for example those on a silicono-organic basis, to flake off, because the copper oxide layer produced during the heat treatment adheres very poorly to the copper and can therefore easily be peeled off with the paint application. So you already have copper conductors with them insulated with temperature-resistant lacquers, intermediate layers of cadmium or nickel or precious metals, like silver, applied. The adhesive strength of the Laeke is still significant with silver and nickel better than copper, but this alone is not decisive. In addition, there is the fact that Depending on the metal the lacquer application takes longer or shorter time to harden. This appearance is probably due to the fact that the metals or metal oxides in question have different strengths Accelerate or retard hardening. This can be due to their chemical properties or through the ability to dissolve more or less well in the paint or to diffuse into it. try have shown that the hardening time for copper is relatively short. With nickel, silver, aluminum but it is almost four times as long. Cadmium or tin coatings as an intermediate layer have the other Disadvantage that they diffuse into the copper conductor and thereby impair its conductivity.
Die Erfindung vermeidet diese Schwierigkeiten. Sie bezieht sich auf ein Verfahren zur Erhöhung der Dauerhaftfestigkeit temperatur beständiger, insbesondere aus siliciumorganischen Lacken bestehender Isolierlacküberzüge auf Kupfer durch eine metallische Zwischenschicht. Erfindungsgemäß wird eine Zwischenschicht aus Eisen aufgebracht.The invention avoids these difficulties. It refers to a method of increasing the Durability of temperature-resistant, in particular of organosilicon lacquers, insulating lacquer coatings on copper by means of a metallic one Intermediate layer. According to the invention, an intermediate layer made of iron is applied.

oder Drähte mit Zwischenschicht aus Eisen selbst nach vierwöchentlicher Wärmebehandlung bei etwa 200° C wiederholt gebogen und gefaltet werden konnten, ohne daß der Lack abplatzte. Auch zeigte die Lackschicht praktisch keine Verfärbung, während in derselben Weise lackierte Kupferbleche oder -drahte ohne Zwischenschicht bereits nach längstens 9stündiger Einwirkung von 200° C bei geringen mechanischen Beanspruchungen die Lackschicht abspringen lassen.or wires with an intermediate layer of iron even after four weeks of heat treatment at about 200 ° C could be bent and folded repeatedly without the varnish flaking off. Also showed the paint layer practically no discoloration, while copper sheets or wires lacquered in the same way without an intermediate layer after a maximum of 9 hours exposure to 200 ° C with low mechanical loads let the layer of paint peel off.
