Description

Verfahren zur Isolierung von elektrischen Leitern, insbesondere für Wicklungen Die Erfindung betrifft einen isolierten elektrischen Leiter für Kabel, Wicklungen, elektrische Geräte usw. und hat zur Aufgabe, einen Leiter mit hitzebeständiger, glimmfester und doch wohlfeiler Isolation zu schaffen. Die Isolation für Leiter nach einem vorgeschlagenen Herstellungsverfahren besteht wenigstens teilweise aus feinsten Glimmerschüppchen und erhärtendem Bindemittel, wie Phosphorsäure, aromatische Orthokieselsäureester od. dgl.Process for the insulation of electrical conductors, in particular for Windings The invention relates to an insulated electrical conductor for cables, Windings, electrical devices, etc. and has the task of providing a conductor with heat-resistant, To create smolder-proof and yet cheaper insulation. The insulation for conductors according to a proposed manufacturing method consists at least partially of finest mica flakes and hardening binders such as phosphoric acid, aromatic Orthosilicic acid ester or the like.

Die Erfindung betrifft nun ein besonders vorteilhaftes Verfahren zur Isolierung von elektrischen Leitern, bei dem die Isolation ebenfalls wenigstens teilweise aus feinsten. Glimmerschüppchen und erhärtendem Bindemittel besteht. Das Verfahren nach der Erfindung ist dadurch gekennzeichnet, daß der mit einem Kunststoffbindemittel versehene kleinflächige Glimmer im Flammenspritzverfahren auf die elektrisch leitenden. Körper aufgebracht wird. Als Bindemittel eignen sich für diese Flammenspritzverfahren vor allem thermoplastische Stoffe, wie Äthoxylinharze, Polyacrylsäureester, Polyamide, Polystyrole ad. dgl., die zwar für sich allein mehr oder weniger thermoplastische Eigenschaften aufweisen, jedoch wenn sie in geringer Menge mit dem anorganischen Material, wie z. B. Glimmerschüppchen, richtig verteilt und vermengt werden, auch noch bei 150° gute Klebeeigenschaften aufweisen. Für höhere Wärmebeständigkeit bis etwa 200° ist es vorteilhaft, hochwärmebeständige Polymerisationsprodukte, wie z. B. Polytetrafluoräthylen und Monochlortrifluoräthylen, als Bindemittel für den kleinflächigen Glimmer zu verwenden.The invention now relates to a particularly advantageous method for Insulation of electrical conductors, in which the insulation is also at least partly from the finest. Mica flakes and hardening binder consists. That The method according to the invention is characterized in that the with a plastic binder provided small-area mica in the flame spraying process on the electrically conductive. Body is applied. These flame spraying processes are suitable as binders especially thermoplastic materials such as ethoxylin resins, polyacrylic acid esters, polyamides, Polystyrenes ad. Like. Although more or less thermoplastic by themselves Have properties, however, when in small amount with the inorganic Material such as B. Mica flakes, properly distributed and mixed together, too still have good adhesive properties at 150 °. For higher heat resistance up to about 200 ° it is advantageous to use highly heat-resistant polymerization products, such as. B. polytetrafluoroethylene and monochlorotrifluoroethylene, as binders for small areas To use mica.

Die nach dem erfindungsgemäßen Verfahren hergestellten Isolierstoffüberzüge haben neben den verbesserten. thermischen Eigenschaften auch eine geringere Temperaturabhängigkeit der Eigenschaften als die bisher bekannten Isolierstoffüberzüge. Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens liegt vor allem darin, daß nach dem erfindungsgemäßen Verfahren sowohl sehr dünne als auch dickere Schichten der Isolation hergestellt werden können. Unter Umständen läßt sich das Verfahren auch auf Glimmer in Pulverform verwenden, wobei zweckmäßig ein Bindemittel ungefähr gleichen spezifischen Gewichtes zu wählen ist. Hierbei ist es jedoch vorteilhaft, die mit dem Bindemittel vermischte Glimmerpülpe Schwingungen auszusetzen, z. B. in einem Vibrationsbehälter oder in dem betreffenden Behälter ein Rührwerk od. dgl. anzubringen, damit eine gute Vermischung von Pülpe und Bindemittel in die Pistole gelangt.The insulating material coatings produced by the process according to the invention have next to the improved. thermal properties also have a lower temperature dependence the properties than the previously known insulating material coatings. An essential one The main advantage of the process according to the invention is that after the process according to the invention Process produced both very thin and thick layers of insulation can be. Under certain circumstances, the process can also be applied to powdered mica use, it is advisable to use a binder of approximately the same specific weight to choose. In this case, however, it is advantageous to mix it with the binder To expose mica pulp to vibrations, e.g. B. in a vibrating container or in To attach a stirrer or the like to the container in question, so that good mixing is achieved pulp and binding agent got into the gun.
