Die Erfindung betrifft eine schnelltrocknende, spritz- und streichfähige Grundierung zur Herstellung von schweißfesten und korrosionsfesten Schutzschichten auf entzunderten Stahlteilen, die in ihrer weiteren Verarbeitung durch Schweißung miteinander verbunden werden.The invention relates to a quick-drying, sprayable and brushable primer for production of sweat-resistant and corrosion-resistant protective layers on descaled steel parts that are in their further processing can be connected to one another by welding.
Die derzeitig bekannten Grundierungen für vorgenannten Verwendungszweck haben den Nachteil, daß sie beim Schweißen in relativ großem Abstand von der Schweißnaht verbrennen bzw. infolge unzureichender Leitfähigkeit vor der Schweißung entfernt werden müssen. Hierdurch wird ein nochmaliges Säubern und Grundieren der Schweißzone erforderlich.The currently known primers for the aforementioned purpose have the disadvantage that they burn when welding at a relatively large distance from the weld seam or as a result of insufficient Conductivity must be removed before welding. This is another The welding zone must be cleaned and primed.
Zur Verbesserung der elektrischen Leitfähigkeit der Grundierung beigegebener Zinkstaub macht den Grundierungsfilm spröde und führt ebenso wie bei Farben mit Bleiverbindungen zur Entstehung gesundheitsschädigender Dämpfe, die sowohl auf den Schweißer als auch auf die in seiner Umgebung Be- so schäftigten schädigend wirken.Zinc dust added to improve the electrical conductivity of the primer makes the The primer film is brittle and, as with paints with lead compounds, leads to the development of harmful substances Vapors that are harmful to both the welder and those around him.
Auch ist die Trockenzeit dieser Grundierungen verhältnismäßig lang, so daß eine kurzfristige Weiterverarbeitung der grundierten Teile nicht möglich ist.The drying time of these primers is also relatively long, so that further processing can be carried out in the short term the primed parts is not possible.
Die Aufgabe der Erfindung besteht darin, eine Grundierung für zu verschweißende Stahlteile zu schaffen, die in kürzester Zeit aushärtet, beim Schweißen ohne vorherige Entfernung an der Schweißstelle eine möglichst geringe Verbrennungszone aufweist, keine Verbrennungsrückstände hinter- läßt, keine gesundheitsschädigenden Dämpfe entwickelt und jedes andere Anstrichsystem als nachfolgenden Aufbau zuläßt.The object of the invention is to provide a primer for steel parts to be welded that hardens in the shortest possible time, when welding without prior removal of the Welding point has the smallest possible combustion zone, no combustion residues does not develop any harmful vapors and any other paint system than the following Construction allows.
Es wurde gefunden, daß diese Anforderungen von einer Grundierung auf der Basis von pigmentierten Lösungen synthetischer Kunstharze in Benzin- und Benzolhomologen erfüllt werden, welche aus 30 bis 35 Teilen styrolisiertem Alkydharz, 5 bis 10 Teilen Epoxyharzester, 10 bis 15 Teilen Eisenoxydrot, 14 bis 16 Teilen Siliciumcarbid, 2 bis 5 Teilen Zinkchromat, 10 bis 15 Teilen Bariumsulfat und 18 bis 22 Teilen Benzin- und Benzolhomologen besteht.It has been found that these requirements of a primer based on pigmented Solutions of synthetic resins in gasoline and benzene homologues are met, which from 30 to 35 parts of styrenated alkyd resin, 5 to 10 parts of epoxy resin ester, 10 to 15 parts of red iron oxide, 14 to 16 parts of silicon carbide, 2 to 5 parts of zinc chromate, 10 to 15 parts of barium sulfate and 18 to 22 parts gasoline and benzene homologues.
Durch den Einsatz des Epoxyharzesters und des Siliciumcarbides konnte die Verbrennungszone unter

Vermeidung von Verbrennungsrückständen auf je mm beidseitig der Schweißnaht reduziert werden.Avoidance of combustion residues can be reduced to per mm on both sides of the weld seam.
Der Einsatz des styrolisierten Alkydharzes ist ausschlaggebend für die kurze Trockenzeit, während durch den Einsatz blei- und zinkfreier Pigmente die Ausscheidung gesundheitsschädigender Dämpfe vermieden wird.The use of the styrenated alkyd resin is crucial for the short drying time during the use of lead-free and zinc-free pigments avoids the excretion of harmful vapors will.
Durch das Zusammenwirken der vorgenannten Komponenten ist eine Weiterverarbeitung jeglicher Anstrichsysteme möglich.Due to the interaction of the aforementioned components, any further processing is possible Painting systems possible.
