Description

Verfahren zur Herstellung von papierähnlichem Isoliermaterial, welches insbesondere zum Umwickeln von Leitern elektrischer Maschinen dienen soll Die Erfindung betrifft ein Verfahren zur Vexzdelung von Papier, Preßspan oder anderem papierähnlichem Isoliermaterial. Erfindungsgemäß werden diese Materialien zuerst mit Paraffin getränkt und hierauf in öl- löslichen Isolierlack getaucht und getrocknet.Process for the production of paper-like insulating material, which is to be used in particular for wrapping conductors of electrical machines. The invention relates to a process for wrapping paper, pressboard or other paper-like insulating material. According to the invention, these materials are first impregnated with paraffin and then dipped in oil- soluble insulating varnish and dried.

Nach einigen 'Tagen wird das Material durch Liegen an der Luft derartig geschmeidig, daß es wie Wachstuch behandelt und bei spielsweise ohne Bruch um i 8o' gefalzt werden kann.After a few days, the material becomes like this when it is left in the air supple, that it is treated like oilcloth and, for example, without breaking around i 8o 'can be folded.

Eine besonders zweckmäßige Ausführungsart des Verfahrens ist folgende: Das Isoliermaterial wird etwa 20 Minuten lang mein So bis 9o° C heißes Paraffinbad gebracht. Dann wird es herausgenommen und abtropfen lassen. Hierauf wird das so vorbehandelte Isoliermaterial in noch warmem Zustande in stark verdünnten, ofentrocknenden Isolierlack getaucht und nach dein Herausnehmen im Trockenofen bei nicht mehr als 50° C getrocknet. Bei: besonders hoher Beanspruchung des Isoliermaterials, z. B. wenn hohe Widerstandsfähigkeit gegen Nässe verlangt ist, wird es mehrmals nacheinander in Lack getaucht und darauf getrocknet.A particularly useful embodiment of the method is as follows: The insulating material becomes my paraffin bath at a temperature of sun to 90 ° C for about 20 minutes brought. Then it is taken out and drained. Then it becomes so pretreated insulation material while still warm in heavily diluted, oven-drying Dipped insulating varnish and after removing it in the drying oven at no more than 50 ° C dried. In the case of: particularly high stress on the insulating material, e.g. B. if high resistance to moisture is required, it is repeated several times in a row dipped in varnish and dried on it.

Durch das Veredelungsverfahren wird die Durchschlagsfestigkeit auf das zwei- bis dreifache erhöht, die Wasseraufnahme ungefähr auf den zehnten Teil herabgedrückt. Das Verfahren ist leicht und billig ausführbar und erfordert keine besonderen Einrichtungen.The refining process increases the dielectric strength increased by two to three times, the water intake to about a tenth depressed. The method is easy and cheap to carry out and does not require any special facilities.
