Description

Lackierverfahren für Drähte Die bisher gebräuchlichen hacke, die zur Isolierung von Drähten verwendet -werden, werden nach dem heutigen Stande. der Technik hauptsächlich mit SchNverbenzin verdünnt. Die Technik legt neuerdings hesonderenWert darauf, daß der Auftrag der lackisolierten, Drähte b.enzin- und benzolfest ist.Varnishing process for wires The hoe commonly used up to now, which are used for Insulation of wires -to be used-are according to today's standards. of the technique mainly diluted with mineral spirits. Technology has lately been of particular importance Make sure that the application of the enamel-insulated wires is resistant to petrol and benzene.

Versuche haben gezeigt, daß bei Verwendung von Lacken, wie z. B. alkoholischen Schellacklösungen, Asphalt- und öllacken, die. mit organischen Lösungsmitteln hergestellt sind, der Überzug nur wenig benzin-und benzolfest ist.Experiments have shown that when using paints such. B. alcoholic Shellac solutions, asphalt and oil varnishes, the. made with organic solvents the coating is only slightly resistant to petrol and benzene.

Es wurde gefunden, daß die an sich als L berzugslacke für Holz u. dgl. bekannten wäßrigen Lösungen von Schellack in Alka.li@en (s. z. B. das Werk »Handbuch der Lacke-und Firnisindustrie« von S e 1 i g m a n n & Z i e k e , 1930, 4. Auflage, S. 644 und 647) ein besonders geeignetes Mittel zum Isolieren der blanken Drähte sind.It has been found that the aqueous solutions of shellac known per se as L topping varnishes for wood and the like are found in Alka.li@en (see, for example, the work "Handbook of the varnish and varnish industry" by Sigmann & Zieke , 1930, 4th edition, pp. 644 and 647) are a particularly suitable means of insulating the bare wires.

Ein solcher überzug erwies sich als benzin-und benzolfest, z. B. haftete .ein solcher Oberzug nach s4stimdiger Lagerung in Benzol noch völlig fest auf dem Drahte. Außerdem hat ein so hergestellter Lack den Vorzug der Billigkeit. Ferner verursacht die Verdampfung des Lösungsmittels im Gegensatz zu Lacken, die mit Schwerbenzin oder ähnlichen Lösungsmitteln verdünnt sind, keine Belästigung und keine .Feuersgefahr.Such a coating proved to be petrol and benzene-proof, e.g. B. was liable Such an overcoat is still completely solid on the surface after a long period of storage in benzene Wires. In addition, a varnish thus produced has the merit of being cheap. Further causes the evaporation of the solvent in contrast to paints made with heavy fuel or similar solvents are diluted, no nuisance and no risk of fire.

Nach dem Auftrag wird der Lack in bekannter Weise bei höherer, zur molekularen Umlagerung des Schellacks ,ausreichender Temperatur getrocknet, wobei bei Anwendung von wäßrigen Lösungen von Schellack in Alkalien, Alkalicarbonaten oder Ammoniak außerdem der Vorteil erreicht wird, daß eine geringere Trocknungstemperatur als bei alkoholisch gelöstem Schellack genügt.After application, the paint is in a known manner at higher, to molecular rearrangement of the shellac, dried to sufficient temperature, being when using aqueous solutions of shellac in alkalis, alkali carbonates or ammonia also has the advantage that a lower drying temperature than is sufficient for shellac dissolved in alcohol.

Den mit Hilfe von Alkalien, Alkalicarbonaten oder Ammoniak hergestellten Schellacklösungen können in der gleichen Weise hergestellte Lösungen von anderen Harzen, wie z. B. Kopalen, zugesetzt werden.The one made with the help of alkalis, alkali carbonates or ammonia Shellac solutions can be prepared in the same way by others Resins such as B. copals are added.

Claims (1)

PATENTANSPRUCH: Lackierverfahren für Drähte, dadurch e eiclinet, daß der blanke Metallg 'kenn7 draht mit an sich bekannten wäßrigen Lösungen von Schellack in Alkalien, Alkalica.rbonaten oder Ammoniak, gegebenenfalls in Mischung mit in gleicher Weise hergestellten wäßrigen Lösungen, von anderen Harzen überzogen. und der sich bildende Film bei höherer Temperatur getrocknet wird. PATENT CLAIM: Painting process for wires, characterized in that the bare metal wire is coated with other resins with known aqueous solutions of shellac in alkalis, alkali carbonates or ammonia, optionally mixed with aqueous solutions prepared in the same way. and the film which forms is dried at a higher temperature.
