Description

Verfahren zum Lackieren feuerverzinkter Oberflächen Die Erfindung betrifft die Oberflächenbehandlung von feuerverzinkten Gegenständen, beispielsweise von Badewannen, Waschgefäßen u. dgl., um die blanke kristallinische Fläche zu schützen. Es ist bereits bekannt, gegossene Zinkgegenstände mit einem festhaftenden Lack zu versehen, der dem Zinkmetall das Aussehen wertvollerer Metalle gibt. Dazu ist z. B. eine vorherige galvanische Vermessingung notwendig und eine sorgfältige Vorbehandlung, wozu Vorbeizungen gehören. Ferner wurden die Oberflächen polierter Metalle bereits mit einem mit Borsäure versetzten Lack überzogen. Die Borsäure hat dabei den Zweck, die glatte Fläche aufzurauhen und für die Haftung des Lackes besser vorzubereiten.Method of painting hot-dip galvanized surfaces The invention relates to the surface treatment of hot-dip galvanized objects, for example of bathtubs, washing vessels, etc., in order to protect the bare crystalline surface. It is already known to apply a firmly adhering varnish to cast zinc objects which gives the zinc metal the appearance of more valuable metals. For this purpose z. B. a previous galvanic measurement is necessary and a careful pretreatment, which includes pre-pickling. Furthermore, the surfaces of polished metals have already been made coated with a lacquer mixed with boric acid. The purpose of boric acid is to roughen the smooth surface and better prepare it for the paint to adhere.

Demgegenüber besteht die Erfindung darin, daß feuerverzinkte Gegenstände umnittelbar nach ihrer Herstellung mit einem in bekannter Weise mit wenig Säure versetzten durchsichtigen Lack. überzogen werden. Dazu sind vornehmlich Kopal- oder Kunstharzlacke geeignet, die mit etwas Ameisen- oder Buttersäure versetzt sind. Es ist damit möglich, feuerverzinkte Blechgegenstände, also Massenartikel, die eine eingehende Einzelbehandlung wirtschaftlich nicht vertragen, auf einfachste Weise mit einem ansprechenden und festhaftenden Lacküberzug zu versehen.In contrast, the invention consists in that hot-dip galvanized objects After their preparation, they can be mixed in a known manner with a little acid offset clear varnish. be coated. These are mainly copal or Synthetic resin lacquers with a little formic or butyric acid are suitable. It is thus possible to produce hot-dip galvanized sheet metal objects, i.e. mass-produced items that have a in-depth individual treatment not economically tolerated, in the simplest way to be provided with an attractive and firmly adhering lacquer coating.

Solche Lacke erhalten z. B. folgende ,Zusammensetzung 99 % Lack und I % Säure bis etwa 99,4 % Lack und o,6_% Säure.Such varnishes receive z. B. the following, composition 99% paint and I% acid to about 99.4% lacquer and 0.6% acid.

Der geringe Säurezusatz hat den Zweck, etwa auf dem Zinküberzug bereits entstandene Oxvde zu entfernen. Ein Anätzen der verzinkten Oberfläche ist nicht erforderlich, weil diese infolge ihrer kristallinischen Beschaffenheit bereits eine rauhe Fläche aufweist. Durch dieses Verfahren ist es möglich, die Blechkörper so zu schützen und in ihrem blanken Aussehen zu =erhalten, daß sie dieses auch nach längerem Lagern behalten und infolgedessen besser verkaufsfähig bleiben.The purpose of the small addition of acid is already on the zinc coating, for example to remove the resulting oxides. There is no etching of the galvanized surface necessary because, due to their crystalline nature, they already have a has a rough surface. Through this process it is possible to make the sheet metal body like this to protect and to maintain their shiny appearance, so that they can also look after them longer storage and as a result remain better salable.
