Description
Verfahren zur Herstellung von für die Fertigung von Konservendosen geeigneten, mit Phenolformaldehydharzlacken lackierten Blechen Für die Herstellung von lackierten Blechen, die zur Fertigung von Konservendosen, dienen, konnten bisher härtbare Phenolformaldehydharzlacke nicht verwendet werden, weil infolge der Sprödigkeit der Überzüge bei der nachfolgenden Verformung der Bleche durch Biegen, Ziehen oder Stanzen Beschädigungen der Lack:erung, wie Haarrisse, Abplatzen usw., auftraten. Selbst bei Verwendung eines fetthaltigen Untergrundes oder einer solchen Zivischenschicht treten bei Überzügen aus härtbaren Phenolformaldehydharzen die gleichen Nachteile ein. Durch diese Zerstörungen des Überzuges bzw. der gesamten Lackierung ist die Schutzwirkung der Phcnolaldehydltarze hei den Blechen hinfällig.Process for the production of for the production of cans suitable sheet metal coated with phenol-formaldehyde resin paints For the production of painted metal sheets, which are used for the production of cans, could so far Curable phenol-formaldehyde resin lacquers are not used because of their brittleness of the coatings during the subsequent deformation of the sheets by bending, pulling or Punching damage to the paintwork, such as hairline cracks, flaking, etc., occurred. Even with the use of a fatty subsoil or such an intermediate layer the same disadvantages occur with coatings made from curable phenol-formaldehyde resins a. This destruction of the coating or the entire paintwork is the Protective effect of the phenol aldehyde salts on the metal sheets is no longer applicable.
Zur Herstellung elastischer, biege-, zieh-, Wasser- und kochfester Lackierungen auf derartigen Blechen konnte hinan infolgedessen bisher nur solche elastischen Bindemittel verwenden, die bei Öllacken durch eine bestimmte Mindestmenge an Öl, bei Alkylharzlacken durch eine entsprechende. Menge an Fettsäureanteil gewährleistet werden.For the production of elastic, bending, tensile, water and boiling resistant As a result, painting on such sheets has only been possible up to now Use elastic binders, with oil varnishes by a certain minimum amount on oil, in the case of alkyl resin lacquers by a corresponding. Amount of fatty acids guaranteed will.
Zweck der vorliegenden Erfindung ist es nun, den Zusatz von Fett und Fettsäuren mÖglichst zu ersparen und trotzdem noch elastische Überzüge unter Verwendung von härtbaren Phenolformaldehydharzlacken zu erzielen. Dieses wird gemäß der Erfindung dadurch erreicht, daß nein vor dem Auftragen der härtbarcn Phcnolformaldehydharzlacke mit Lacken auf Grundläge von Polymeii,sations.-produkten grundiert, denen gegebenenfalls bis zu 5o0'o Phenolformaldchydharze zugesetzt sind. Als Polymerisationsprociukte werden für die Grundierung Polymerisate, wie künstlicher Kautschuk; StyrolT. Acryl- oder Vinylderivate, für sich allein oder in Verbindung mit geringen- Mengen ' von- -Phenolaldehydharzen oder deren Abkömmlingen verwendet, wobei der Zusatz dieser Stoffe höchstens 5o0%o betragen soll.The purpose of the present invention is now the addition of fat and To save fatty acids as much as possible and still use elastic coatings of curable phenol-formaldehyde resin lacquers. This is done according to the invention achieved by the fact that no before the application of the curable phenolic formaldehyde resin varnish primed with varnishes based on polymeii, sations.-products, which if necessary up to 50,000 phenol-formaldehyde resins are added. As polymerization products be for the primer polymers, such as artificial rubber; Styrene T. Acrylic or vinyl derivatives, on their own or in conjunction with minor Amounts of phenol aldehyde resins or their derivatives are used, the The addition of these substances should not exceed 50%.
Durch die gemäß der Erfindung benutzte Grundierung werden die verschiedenen AusdAnungskoeffizienten zwischen Metall und Überzugslack ausgeglichen. so daß beim Biegen, Ziehen oder Stanzen keine Beschädigungen der Lackierung auftreten. Es werden damit hoch biegefeste, stanzfeste. Wasser- und kochfeste Lackierungen erhalten. ' Zur Erhöhung der Wasserfestigkeit bzw. Kochfestigkeit können den reinen Polymerisationsprodukten, je nach deren Einstellung, noch gewisse Anteile .vasserabweisender Mittel, wie z. B. Paraffin, aber nur in geringer Menge, so z. B. bis zu io0!o, .oder anderer Harzkörper zugesetzt werden.With the primer used according to the invention, the various Expansion coefficient balanced between metal and top coat. so that at Bending, pulling or punching does not damage the paintwork. It will thus highly bending-resistant, punch-resistant. Preserved water and boil-proof paintwork. '' To increase the water resistance or boiling resistance, the pure polymerization products, depending on their setting, still certain proportions. B. paraffin, but only in small amounts, such. B. up to io0! O, .or other resin bodies can be added.
Die elastischen Polymerisate und die Plienolformaldehvdharze können in den üblichen Lösungsmitteln, Lösungsmittelgemischen, Wasser oder deren Gemischen, je nach der Verarbeitungsart, gelöst zur Verwendung kommen.The elastic polymers and the Plienolformaldehvdharze can in the usual solvents, solvent mixtures, water or mixtures thereof, depending on the type of processing, can be used as a solution.
Es ist bereits bekannt, Lacke auf Grundlage von Polymerisationsprodukten als Grundierun.gsmittel für Metalle u:. dgl. zu verwenden. Hieraus war aber nicht zti entnehmen, daß derartige Lacke eine brauchbare Grundierung für eine Lackierung mit härtbaren Phenolformaldehydharzlacken auf Blechen, die für ,die Fertigung von Konservendosen bestimmt sind und deren Lackierung besonderen Anforderungen genügen muß, darstellen.It is already known, paints based on polymerization products as a primer for metals etc. Like. To use. But it wasn't from this zti infer that such paints are a useful primer for a paint job with curable phenol-formaldehyde resin lacquers on sheet metal, which are used for, the manufacture of Food cans are intended and their paintwork meets special requirements must represent.
