Description
Verfahren zur Herstellung von Schutzschichten auf Gegenständen aus magnetisierbaren Werkstoffen Es besteht in der Technik die Aufgabe, Gegenstände, die aus mehreren Lagen oder Schichten aus hochwertigen magnetisierbaren Werkstoffen bestehen, gegen mechanische Verformungen zu schützen und sie gegen darauf aufzubringende Metallteile zu isolieren.Process for the production of protective layers on objects magnetizable materials In technology, the task is to create objects, those made of several layers or layers of high-quality magnetizable materials exist to protect against mechanical deformations and to protect them from being applied to it Insulate metal parts.
Es ist bekannt, Magnetkerne in Isoliermassen einzubetten, die unter Einwirkung des Luftsauerstoffes oder durch Wärmebehandlung hart werden. Dabei wurde auch schon vorgeschlagen, in die Isoliermassen Fasern oder sonstiges Füllmaterial einzubringen. Solche Isolierschichten haben aber den Nachteil, daß sie für Gegenstände aus hochwertigen magnetisierbaren Werkstoffen nicht benutzt werden können, weil die beim Festwerden dieser Isolierschichten auftretenden Schrumpfspannungen die magnetischen Eigenschaften der genannten Werkstoffe in merkbarer Weise verschlechtern.It is known to embed magnetic cores in insulating materials that are below Exposure to atmospheric oxygen or hardening through heat treatment. It was already proposed, fibers or other filler material in the insulating masses bring in. Such insulating layers have the disadvantage that they are used for objects made of high-quality magnetizable materials cannot be used because the shrinkage stresses that occur when these insulating layers become solid magnetic properties of the materials mentioned deteriorate in a noticeable manner.
Zur Isolierung elektrischer Bauelemente sind aber auch bereits Isoliermassen auf Chlo:rnaphthalinbasis bekanntgeworden, die einen wachsartigen Charakter besitzen. Das Einbetten von Magnetkernen in derartige Isoliermassen bietet keinen genügenden Schutz gegen äußere mechanische Beanspruchungen, da diese Massen zu weich sind.However, insulating compounds are already used to isolate electrical components based on chlorine, which have a waxy character. Embedding magnetic cores in such insulating compounds is not sufficient Protection against external mechanical loads, as these masses are too soft.
Es wurde weiterhin bereits vorgeschlagen, mit Wicklungen versehene Magnetkernanordnungen mit übereinanderliegenden Schichten aus Isoliermasse zu versehen, wovon die erste Schicht weich und nachgiebig und die äußere Schicht hart und fest sein sollte. Ein derartiger Schutz gestattet wohl, die durch die Betriebswärme der Wicklung entstehende Längenausdehnung aufzunehmen und dadurch ein Reißen der äußeren, harten Schicht zu verhindern. Eine Verspannung des Magnetkernes durch die aufgebrachte Erregerwicklung kann aber auch durch die nachgiebige Schicht, die den bewickelten Kern umgibt, nicht mehr aufgehoben werden.It has also been proposed to provide windings To provide magnetic core assemblies with layers of insulating compound lying one on top of the other, of which the first layer is soft and pliable and the outer layer hard and firm should be. Such protection probably allows the by the operating heat of Take up the length expansion occurring in the winding and thereby tear the outer, to prevent hard layer. A tension of the magnetic core by the applied Excitation winding can, however, also through the flexible layer that wraps the Surrounds core, can no longer be canceled.
Ferner wurde vorgeschlagen, Magnetkerne aus hochwertigen magnetisierbaren Werkstoffen mit einer Kunststoffschaumumhüllung zu versehen und diesen so geschützten Kern in eine Kapsel einzulegen. Diese Anordnung hat den Nachteil, daß das Wickelfenster durch die Kunststoffschaumschicht und die Kapsel in unerwünschter Weise verkleinert wird. Darüber hinaus beanspruchen solche Kerne beim Einbau in Apparate einen verhältnismäßig großen Raum.It has also been proposed to make magnetic cores from high-quality magnetizable To provide materials with a plastic foam cover and thus protect them Put the core in a capsule. This arrangement has the disadvantage that the winding window reduced in size in an undesirable manner by the plastic foam layer and the capsule will. In addition, such cores require a relatively high load when installed in apparatus great room.
Nach dem erfindungsgemäßen Verfahren werden Schutzschichten auf Gegenständen, die aus mehreren Lagen oder Schichten aus hochwertigen magnetisierbaren Werkstoffen bestehen, unter Verwendung von an sich bekannten Kunststoffmassen mit kleinem Schwund beim Festwerden oder Aushärten dadurch hergestellt, daß auf die Gegenstände unmittelbar eine 1-r 1. 1 Schicht aus. Isoliermasse auf Chlornaphthalinbasis, gemischt mit Po:lys.trol, Polyvinylchlorid oder ähnlichen Kunststoffen, aufgebracht und auf diese Schicht eine Außenschicht aus Äthoxylinharz aufgetragen wird. Durch solche Doppelschichten werden die beschichteten Gegenstände gegen mechanische Verformungen geschützt und gegen darauf aufzubringende Metallteile, insbesondere Band- oder Drahtwicklungen, isoliert.According to the method according to the invention, protective layers are produced on objects that consist of several layers or layers of high-quality magnetizable materials, using known plastic compounds with small shrinkage when solidifying or hardening, in that a 1-r 1. 1 Layer off. Insulating compound based on chloronaphthalene, mixed with Pol: lys.trol, polyvinyl chloride or similar plastics, is applied and an outer layer of ethoxylin resin is applied to this layer. Such double layers protect the coated objects from mechanical deformation and insulate them from metal parts to be applied to them, in particular tape or wire windings.
Die unmittelbar auf den Gegenstand aufgetragene Schicht aus Isoliermasse ist weich und nachgiebig, während die Außenschicht aus Äthoxylinharz hart und fest ist.The layer of insulating compound applied directly to the object is soft and pliable, while the outer layer of ethoxylin resin is hard and firm is.
Durch die gemäß der Erfindung als Pufferschicht wirkende Schicht aus Isoliermasse auf Chlornaphthalinbasis werden äußere mechanische Spannungen vom Magnetkern möglichst ferngehalten, so daß die hochgezüchteten magnetischen Eigenschaften des Kernes weitgehend erhalten bleiben.By the layer acting as a buffer layer according to the invention Insulating compound based on chloronaphthalene removes external mechanical stresses from the magnetic core as far away as possible, so that the highly cultured magnetic properties of the Kernes are largely preserved.
Das Aufbringen der erfindungsgemäß zum Einbetten der genannten Gegenstände verwendeten Isoliermassen kann z. B. durch Pressen, Tauchen, Gießen oder Spritzen erfolgen.The application of the invention for embedding the objects mentioned Insulation compounds used can, for. B. by pressing, dipping, pouring or spraying take place.
Das Verfahren ist unter anderem auch auf Gegenstände aus solchen Eisen-Silizium-Legierungen anwendbar, die durch besondere Kaltverformung und Wärmebehandlung besonders ausgezeichnete magnetische Eigenschaften besitzen, z. B. besonders hohe Anfangspermeabilität und besondere Schleifenform der Magnetisierungskurve (Rechteckschleife).The procedure is among other things also on objects made of such iron-silicon alloys applicable, which are particularly excellent due to special cold forming and heat treatment have magnetic properties, e.g. B. particularly high initial permeability and special loop shape of the magnetization curve (rectangular loop).
