Description
Verfahren zur Herstellung lackierter, nahtlos gepreßter Formkörper Es ist allgemein bekannt, nahtlos gepreßte Formkörper aus Blechen, z. B. Schachteln, Dosen usw., durch Tauchen oder Spritzen mit einem Lack zu überziehen. Dieses Verfahren ist jedoch umständlich und zeitraubend. Es wurde daher auch bereits vorgeschlagen, die Bleche vor der Verformung zu lackieren, wobei natürlich an .die Lacke sehr hohe Anforderungen gestellt werden. Es kamen hierfür bisher lediglich ofentrocknende Lacke, z. B. Phenolformaldehydhärzlacke, in Frage, die jedoch auf den Blechen vor der Verformung eingebrant werden müssen.Process for the production of lacquered, seamlessly pressed moldings It is well known to produce seamlessly pressed shaped bodies made of sheet metal, e.g. B. boxes, Can, etc., to be coated with a lacquer by dipping or spraying. This method however, it is cumbersome and time consuming. It has therefore already been suggested that to paint the sheets before the deformation, of course at .the paints very high Requirements are made. So far, only oven-drying ones have been used for this purpose Varnishes, e.g. B. Phenolformaldehydharzlacke, in question, however, on the metal sheets the deformation must be incorporated.
Es wurde nun überraschenderweise gefunden, daß man auch lufttrockneude Lackft. verwenden kam, wenn man dieselben auf der Grundlage von Polyvinylverbiudungen aufbaut. Die allgemeinen Eigenschaften der Polyvinylharzlacke, z. B. gute Haft- und Biegefestigkeit, sind zwar allgemein bekannt; es war jedoch nicht zu erwarten, daß sie derartig starken Beanspruchungen, wie sie beim nahtlosen Preßformen aufeeten,ohne zu reißen, gewachsen seid würden. Gute Haft- und Biegefestigkeit rühmt man nämlich auch einer großen Zahl von anderen lufttrocknenden Lacken, z. B. solchen auf der Grundlage von. Acetyloelluloise, nach, ohne daß dieselben etwa für den vorliegenden Fall geeignet wären.It has now surprisingly been found that air-drying can also be used Lackft. came to use when you use the same on the basis of Polyvinylverbiudungen builds up. The general properties of polyvinyl resin paints, e.g. B. good adhesive and flexural strength, are well known; however, it was not to be expected that they are subjected to such strong stresses as they arise in seamless compression molding without to tear, would have grown. They praise good adhesion and flexural strength also a large number of other air-drying paints, e.g. B. such on the Based on. Acetyloelluloise, after, without the same about for the present Case would be appropriate.
Als Lackgrundkörper kommen erfiudungsgemäß an sich bekannte Polyvinylverbindungen, wie Polyvinylacetat, Polyacrylsäureester, Mischpolymerisate, Polyvinylchlorid, nachchloriertes Polyvinylchlorid u. dgl., in Frage. Setzt man den Lacken Metallpulver, z. B. Aluminiumpulver, zu, so, erhält man Fo@rmkörper, die das Aussehen von reinem Aluminium haben.According to the invention, known polyvinyl compounds are used as the lacquer base, such as polyvinyl acetate, polyacrylic acid esters, copolymers, polyvinyl chloride, post-chlorinated Polyvinyl chloride and the like. If you put the paints metal powder, z. B. aluminum powder, to, so, one obtains molded bodies which have the appearance of pure aluminum.
Besonders muß ferner überraschen, daß man mit einer verhältnismäßig dünnen Lackschicht auskommt, z. B. im Falle von PolyvinylchloTid mit etwa zog Lack pro Quadratmeter. Der Auftrag der Lackschicht erfolgt zweckmäßig in an sich bekannter Weise mittels Walzen. Die der Lacke kann auf Grund der Auswahl der ,an sich für PoIyvinylverbinduingen in großer Zahl bekannten Lösungsmittel bzw. Lösungsmittelgemische so einsgestellt werden, daß unmittelbar oder nahezu unmittelbar anschließend an die Lackierung die Verformung erfolgen kann. Der hierdurch erzielte Fortschritt gegenüber. den bisher für solche Zwecke allein ver wendeten ofentrocknenden Lacken liegt atuf der Hand, da das vorliegende Verfahren wesentlich schneller und billiger arbeitet.Particularly must also surprise that one with a proportionate thin layer of varnish, z. B. in the case of PolyvinylchloTid with about pulled paint per square meter. The application of the lacquer layer is expediently carried out in a manner known per se Way by means of rollers. Which of the paints can be based on the selection of, per se for Polyvinylverbinduingen in large numbers known solvents or solvent mixtures so be set that immediately or almost immediately following the Painting the deformation can take place. The progress made as a result. the oven-drying paints that have hitherto been used for such purposes alone are atuf the hand, since the present method works much faster and cheaper.
Hinzu kommt auch, daß gewisse Polyvinylverbindungen gegenüber z. B. Phenolformaldehydharzlacken den Vorteil einer höheren Säure- und Alkalibestän digkeit aufweisen.In addition, certain polyvinyl compounds compared to z. B. Phenol-formaldehyde resin paints have the advantage of higher acid and alkali resistance exhibit.
