Description
Herstellung von lufttrocknenden Decklackierungen auf Metallen Gegenstand der Erfindung ist die Verwendung von Lacken mit auf Basis Hexachlorendomethylentetrahydrophthalsäure (im folgenden als Hetsäure bezeichnet) in an sich bekannter Weise erhaltenen Alkydharzen zur Herstellung von lufttrocknenden Decklackierungen auf Metallen.Manufacture of air-drying topcoats on metal object the invention is the use of paints based on hexachloroendomethylenetrahydrophthalic acid (hereinafter referred to as Hetsäure) alkyd resins obtained in a manner known per se for the production of air-drying topcoats on metals.
Die Verwendung magerer Alkydharze, die durch Kondensation von Phthalsäure oder Phthalsäureanhydrid mit mehrwertigen Alkoholen und pflanzlichen oder tierischen'Olen hergestellt sind, zu lufttrocknenden Lacken für die Oberflächenbeschichtung insbesondere von Metallen ist bekannt. Diese Filme haben aber den Nachteil, daß sie lange Trocknungszeiten erfordern, eine geringe Oberflächenhärte erreichen und nur eine geringe Wasser-und Tropenfestigkeit besitzen. The use of lean alkyd resins produced by condensation of phthalic acid or phthalic anhydride with polyhydric alcohols and vegetable or animal oils are made to air-drying paints for surface coating in particular of metals is known. However, these films have the disadvantage that they have long drying times require to achieve a low surface hardness and only a low water and Have tropical stability.
Weiterhin ist aus der USA.-Patentschrift 2 873 210 bekannt, Alkydharze auf Basis Hetsäure mit einem Olgehalt von 20 bis 45°/o herzustellen, die bei einem Mehrschichtenlacksystem für Metallflächenüberzüge bei Grundierlacken als Bindemittel dienen, um eine gute Haftung des Decklackes auf Basis von Methacrylsäurepolymeren zu bewirken. Bei der Herstellung dieser Alkydharze können neben der Hetsäure noch unsubstituierte Dicarbonsäuren, z. B. Furthermore, from US Pat. No. 2,873,210, alkyd resins are known to produce based on Hetsäure with an oil content of 20 to 45%, the one Multi-layer paint system for metal surface coatings in primers as a binder serve to ensure good adhesion of the topcoat based on methacrylic acid polymers to effect. In the production of these alkyd resins, in addition to the Hetsäure unsubstituted dicarboxylic acids, e.g. B.
Phthalsäure, verwendet werden. Diese Alkydharze werden ausschließlich in Einbrenngrundierungen eingesetzt, deren Einbrenntemperaturen bei 150 bis 200°C liegen, wobei als Behandlungszeiten bis zu 60 Minuten benötigt werden.Phthalic acid. These alkyd resins are exclusive used in stoving primers with stoving temperatures of 150 to 200 ° C lying, with treatment times of up to 60 minutes being required.
Es wurde nun gefunden, daß sich Uberzugsmittel mit Alkydharzen dieser Art auch zur Herstellung von lufttrocknenden Decklackierungen auf Metallen eignen. It has now been found that coating agents with alkyd resins are compatible with these Art is also suitable for the production of air-drying topcoats on metals.
Die Alkydharze für die erfindungsgemäß für Uberzugsmittel für Metalle verwendeten Lacke werden durch Umsetzung von Hetsäure, die teilweise durch gesättigte zweibasische Carbonsäuren ersetzt sein kann, mit mehrwertigen Alkoholen und pflanzlichen oder tierischen Ülen in an sich bekannter Weise erhaltenen und in aromatischen oder aliphatischen Lösungsmitteln oder deren Gemischen gelöst. The alkyd resins for the coating agents for metals according to the invention The paints used are made by reacting Hetsäure, partially saturated by Dibasic carboxylic acids can be replaced with polyhydric alcohols and vegetable or animal oils obtained in a manner known per se and in aromatic or dissolved aliphatic solvents or mixtures thereof.
Ihr Ulgehalt beträgt 35 bis 45°/o.Their Ul content is 35 to 45 per cent.
Die Kondensation wird zweckmäßig so lange durchgeführt, bis eine Viskosität von 4500 bis 5500 cP 70°/oig in Xylol erreicht ist. Als geeignete Ule sind z. B. Sojaöl, Ricinenöl, Safloröl, harzsäurefreies Tallöl oder Sonnenblumenöl zu nennen. Als rriehrwertige Alkohole eignen sich z. B. Glycerin, Hexantriol, Pentaerythrit und Trimethylolpropan. Die daraus erhaltenen Decklackschichten trocknen bereits an der Luft und besitzen eine in der Technik bisher unbekannte Härte sowie eine ausgezeichnete Wasser-und Tropenbeständigkeit. Die erfindungsgemäß ermöglichte Herstellung von wasser-und tropenbeständigen Metallüberzügen in einem Arbeitsgang ohne Anwendung höherer Temperaturen unter Verwendung nur einer Harzkomponente stellt daher einen wesentlichen technischen Fortschritt gegenüber den bekannten Lacksystemen dar. The condensation is expediently carried out until one Viscosity of 4500 to 5500 cP 70% in xylene is reached. As a suitable Ule are z. B. soybean oil, ricin oil, safflower oil, resin-acid-free tall oil or sunflower oil to call. Suitable alcohols are, for. B. glycerol, hexanetriol, pentaerythritol and trimethylol propane. The resulting topcoat layers are already drying in the air and have one in technology so far unknown hardness as well as an excellent one Water and tropical resistance. The production of water and tropicalized metal coatings in one operation without application higher temperatures using only one resin component therefore provides one represents significant technical progress compared to the known paint systems.
Beispiel 1 511 Gewichtsteile Hetsäure, 105 Gewichtsteile Pentaerythrit, 154 Gewichtsteile Sojaöl und 277 Gewichtsteile Ricinenöl werden nach Zusatz von 100 Gewichtsteilen Xylol unter Durchleiten eines C02-Stromes und unter Rühren langsam auf 150 bis 190°C erhitzt. Das gebildete Reaktionswasser wird mit dem im Kreislauf geführten Xylol azeotrop überdestilliert und in einem Wasserabscheider abgetrennt. Die Kondensation wird so lange durchgeführt, bis eine Viskosität von 4500 bis 5500 cP, gemessen 70°/oig in Xylol, erreicht ist. Anschließend wird das Alkydharz 70°/oig in Xylol gelöst. Example 1 511 parts by weight of heteric acid, 105 parts by weight of pentaerythritol, 154 parts by weight of soybean oil and 277 parts by weight of ricin oil are added after 100 parts by weight of xylene while passing through a stream of CO 2 and slowly stirring heated to 150 to 190 ° C. The water of reaction formed is circulated with the led xylene distilled over azeotropically and separated in a water separator. The condensation is carried out until a viscosity of 4500 to 5500 cP, measured 70% in xylene, is reached. The alkyd resin is then 70% dissolved in xylene.
Bei Verwendung dieses Alkydharzes in lufttrocknenden Einschicht-und Decklacksystemen wird nach Beschichtung auf Metall eine Staubtrocknung nach etwa 30 Minuten erreicht. Die Pendelhärte (Persoz) beträgt bei einer Schichtdicke von 30 bis 35 Z nach einem Tag etwa 100 Sekunden, nach 4 Tagen etwa 150 Sekunden und steigt nach einer Woche auf über 200 Sekunden an. Außerdem zeichnen sich diese Filme durch vorzügliche Wasser-und Tropenbeständigkeit aus. When using this alkyd resin in air-drying single-layer and After coating on metal, topcoat systems will dust dry after about 30 minutes reached. The pendulum hardness (Persoz) is at a layer thickness of 30 to 35 Z after one day about 100 seconds, after 4 days about 150 seconds and increases to over 200 seconds after a week. Also, these films stand out through excellent water and tropical resistance.
