Description

Verfahren zum überziehen der Innenflächen von Kraftfahrzeug-Treibstofftanks mit härtbarem Kunstharz Bei den Kraftfahrzeug-Treibstofftanks besteht bisher der Mangel, daß es nicht gelingt, im Innern, insbesondere an den Schweißstel,-len, von Schlingerwänden und Bodenflächen einen vollflächigen Überzugsfilm herzustellen, der sich auch während der Benutzung fehlerlos erhält. Bei Treibstoffen, die das zur Herstellung der Tanks benutzte Eisenblech anzugreifen vermögen, wie z. B. Methanol und Dieselöl, besteht die Gefahr, daß auch bei den geringsten Lücken in dem auf der Innenwand des Treibstoffbehälters angebrachten Schutzüberzug Ausfressungen des Metalls unter allmählich weiter -fortschreitender Zerstörung ,des Films eintreten. Durch die dabei gleichzeitig auftretende Verunreinigung des Treibstoffs wird dieser praktisch unbrauchbar. Da diese Ausfressungen und Zerstörungen des Films meist an solchen Stellen der Innenoberfläche auftreten, die bei der Prüfung des Tanks auf seine Brauchbarkeit nicht ohne weiteres festgestellt werden können, sind sie in besonderem Maße bedenklich.Process for coating the interior surfaces of automotive fuel tanks with curable synthetic resin In the case of motor vehicle fuel tanks, the Deficiency that it does not succeed in the interior, especially on the welding point, -len, of To create a full-surface coating film for rolling walls and floor surfaces, which is maintained flawlessly even during use. For fuels that do able to attack sheet iron used to manufacture the tanks, such as B. methanol and diesel oil, there is a risk that even the slightest gaps in it will result the protective coating attached to the inner wall of the fuel tank Metal with gradual further-advancing destruction of the film. Due to the contamination of the fuel that occurs at the same time, it becomes practically useless. Since this erosion and destruction of the film mostly occurs such spots on the inner surface occur when testing the tank its usefulness cannot be determined without further ado, they are in particularly questionable.

Durch .das Verfahren gemäß der Erfindung werden diese Mängel vermieden. Man arbeitet in der Weise, daß man in den Behälter Kunstharzlack in der erforderlichen, nach Erfahrungen leicht zu ermittelnden Menge eingießt, den Tank in der bekannten Weise dreht oder schwenkt und von außen bis zur vollständigen Härtung des Kunstharzfilms erhitzt, wobei die entstehenden Lösungsmitteldämpfe #übgesaugt werden.The method according to the invention avoids these deficiencies. One works in such a way that one in the container synthetic resin paint in the required, according to experience, easy to determine amount pours the tank in the known Way rotates or pivots and from the outside until the synthetic resin film has hardened completely heated, the resulting solvent vapors # are sucked over.

Als Kunstharzlacke kommen alle an sich bekannten in Frage, insbesondere Formaldehydkunstharzlacke.All known per se are suitable as synthetic resin lacquers, in particular Formaldehyde synthetic resin paints.

Die Bedeutung der Erfindung wird vor allem auf :dem Gebiet der Tanks für Militärfahrzeuge gesehen, weil nachdem neuen Verfahren ein Überzug erhalten wird, der die bei Militärfalirzeugeti geforderte schnellwechelnde -Tankfiillung mit verschiedenartigen Brennstoffen gestattet, ohne die Brauchbarkeitsdauer des Tänks irgendwie zu beeinflussen.The importance of the invention is mainly on: the field of tanks seen for military vehicles because received a coating according to the new process who is the at Military falirzeugeti demanded quick changing -Filling with various fuels is permitted without affecting the useful life to somehow influence the potion.
