Abstract

A non-UV-resistant synthetic resin-based binder is used in a coating material containing more than 40 wt% metallic copper pigment in a solvent or binder, which is used especially for roofing articles such as guttering, downpipes, guttering irons, snow holding grids, foot gratings and skylights etc.

Description

Die Erfindung betrifft eine Beschichtung insbesondere für Bedachungsartikel wie Dachrinnen, Fallrohre, Rinneisen, Schneefanggitter, Trittroste, Dachfenster und dergleichen, bei der in einem Löse- bzw. Bindemittel metallische Kupferpigmente in einem Anteil < 40 Gew.-% enthalten sind.The invention relates to a coating in particular for Roofing articles such as gutters, downspouts, gutter bars, Snow guards, step gratings, skylights and the like, at the metallic copper pigments in a solvent or binder are contained in a proportion <40% by weight.

Die erwähnten Bedachungsartikel und deren Zubehör bestehen überwiegend aus korrosionsgeschützten Metallen wie verzinktem Stahl, Zink oder Kupfer. Insbesondere für stark korrosions­ gefährdete Bedachungsartikel wie Dachrinnen wird bevorzugt Kupfer verwendet, da es aufgrund seiner Stellung in der elek­ trochemischen Spannungsreihe nahezu zu den Edelmetallen zählt und praktisch korrosionsfest ist. Lediglich die ursprünglich metallisch kupferfarben glänzende Oberfläche bildet durch Witterungseinflüsse im Laufe der Zeit unter Dunkelfärbung dünne Oberflächenschichten aus, die z. B. aus Kupferoxiden und Kupfersalzen besteht. Diese Oberflächenschicht dient jedoch dem darunter liegenden Metall als Schutz vor weiterer Korro­ sion, so daß Kupferdachrinnen über viele Jahrzehnte ohne Un­ dichtigkeiten verwendet werden können.The roofing articles and their accessories mentioned exist mainly from corrosion-protected metals such as galvanized Steel, zinc or copper. Especially for severe corrosion Endangered roofing items such as gutters are preferred Copper is used because of its position in the elec trochemical voltage series is almost a precious metal and is practically corrosion-resistant. Only the original one metallic copper-colored glossy surface forms Weather influences over time under darkening thin surface layers from z. B. from copper oxides and Copper salts exist. However, this surface layer serves the metal underneath as protection against further corrosion sion, so that copper gutters for many decades without Un tightness can be used.

Ein Nachteil von Kupfer ist jedoch der vergleichsweise hohe Preis, so daß dadurch seine Verwendung für die beschriebenen Artikel begrenzt wird.A disadvantage of copper, however, is the comparatively high level Price, so that its use for the described Article is limited.

Wenn jedoch beispielsweise die Dachrinnen und Fallrinnen eines Hauses aus metallischem Kupfer und das restliche Dachzubehör z. B. aus verzinktem Stahl besteht, können sich durch die unterschiedlichen Materialen architektonische bzw. ästhetische Defizite ergeben, so daß dann häufig ganz auf den Einsatz von Kupferartikeln verzichtet wird, um ein einheitliches Bild des Daches bzw. Hauses zu erhalten.However, if, for example, the gutters and gutters are one  Metallic copper house and the rest of the roof accessories e.g. B. consists of galvanized steel, can by different materials, architectural or aesthetic Deficits result, so that then often entirely on the use of Copper items is dispensed to create a unified picture of the Obtain roof or house.

Der Erfindung liegt die Aufgabe zugrunde, eine Beschichtung insbesondere für Bedachungsartikel zu schaffen, die auf nicht kupferhaltige Materialien aufgebracht werden kann und sich in gleicher Weise wie metallisches Kupfer im Laufe der Zeit dun­ kel verfärbt.The invention has for its object a coating especially for creating roofing items that are not on copper-containing materials can be applied and in same way as metallic copper dun over time discolored.

Diese Aufgabe wird dadurch gelöst, daß ein nicht UV-Licht beständiges Bindemittel auf Kunstharzbasis verwendet wird.This object is achieved in that a non-UV light Resistant binder based on synthetic resin is used.

Im Gegensatz zu den herkömmlichen Kupferlacken, bei denen großer Wert auf eine Witterungsbeständigkeit gelegt wird und die sich praktisch nicht verfärben, gelingt es durch den Ein­ satz des gegen UV-Licht nicht beständigen Bindemittels, ähnli­ che Alterungsverfärbungen wie bei metallischem Kupfer hervor­ zurufen.In contrast to the conventional copper lacquers, where great importance is attached to weather resistance and those that practically do not discolor, succeed through the on set of the binder not resistant to UV light, similar aging discoloration as with metallic copper shout.

Daher kann ein einheitliches Erscheinungsbild beispielsweise eines Daches bewirkt werden, ohne daß für die Bedachungsarti­ kel metallisches Kupfer als Grundmaterial verwendet werden muß. Durch die Verwendung des nur begrenzt UV-beständigen Bindemittels wird in erster Linie zunächst die Oberflächen­ schicht der Beschichtung angegriffen, so daß die in der Be­ schichtung vorhandenen metallischen Kupferpigmente freigegeben werden und, wie lange Versuchsreihen gezeigt haben, unter nahezu identischen Verfärbungen altern.Therefore, for example, a uniform appearance a roof can be effected without the roofing kel metallic copper can be used as the base material got to. By using the only UV-resistant The binder is primarily the surfaces layer of the coating attacked, so that in the loading layering of existing metallic copper pigments and, as long test series have shown, under almost identical discoloration ages.

Die den Witterungseinflüssen nunmehr unterliegenden Kupferpig­ mente in der Beschichtungsoberfläche verhindern gleichzeitig zunehmend einen weiteren Verlust des Bindemittels, da sie den Zutritt der natürlichen UV-Strahlung in untere Schichten ver­ hindern. Die Beschichtung verbessert daher trotz der nicht beständigen Bindemittel den Korrosionsschutz der beschichteten Metalle.The copper pig now subject to the weather prevent elements in the coating surface at the same time increasingly further loss of the binder as it Access to natural UV radiation in lower layers ver prevent. The coating therefore does not improve despite that  resistant binders provide corrosion protection for the coated Metals.

Als Bindemittel sind dabei praktisch alle Kunstharze verwend­ bar, die keine UV-Licht absorbierenden Verbindungen enthalten. Derartige Verbindungen sind z. B. Derivate des Benzophenons, substituierte Benzotriazole, Phenyl-substituierte Acrylate, Salicylate oder organische Nickelkomplexe, die den üblichen Beschichtungsstoffen als sogenannte UV-Stabilisatoren zuge­ mischt werden. Als geeignete Kunstharze kommen insbesondere alle Polymere bis auf Fluorpolymere oder Siloxane in Frage.Virtually all synthetic resins are used as binders bar that do not contain any compounds that absorb UV light. Such connections are e.g. B. derivatives of benzophenone, substituted benzotriazoles, phenyl-substituted acrylates, Salicylates or organic nickel complexes, the usual Coating materials as so-called UV stabilizers to be mixed. Suitable synthetic resins come in particular all polymers except fluoropolymers or siloxanes in question.
