Description
Rostschutzfarbe-Rostschutzfarben bestehen in der Regel aus einem Bindemittel und einem Farbpigment; letzteres soll gegen -alle das Eisen angreifenden chemischen Beanspruchungen durch die Atmosphäre möglichst widerstandsfähig sein. Man wählt deshalb als Rostschutzpigmente meist Metalloxyde, die mit Sauerstoff gesättigt sind, weil der Sauerstoff der Luft an ihnen keine Angriffsmöglichkeit findet. Zur Verhinderung elektrolytischer Korrosion ist es zweckmäßig, den .verschiedenen Metallen ihre eigenen Oxyde aufzustreichen, um die Bildung der schädlichen Potentialspannungen zwischen Metall und Anstrich zu vermeiden.Rust protection paints rust protection paints usually consist of a binder and a color pigment; the latter is said to be against all chemical attacking iron Be as resistant as possible to stresses caused by the atmosphere. One chooses therefore, as rust protection pigments, mostly metal oxides that are saturated with oxygen, because the oxygen in the air cannot attack them. To prevent electrolytic corrosion it is advisable to give the different metals their own Spread oxides to prevent the formation of harmful potential voltages between Avoid metal and paint.
Es ist schon versucht worden, ` durch Schmelzen von eisenhaltigen, unreinen Ausgangsstoffen, wie natürlichen Eisenerzen, Limoniten und Pyritabbräriden, Gemischen aus Eisenteilen mit Eisenoxyd;:Eisenoxyduloxyden mit überschüssigem Oxydul, oder von Eisensalzen, z. B. Abfallsalzen, ferner von Eisenlegierungen oder durch Kalk verunreinigten Eisenoxyden Rostschutzpigmente herzustellen. Derartige Schmelzen enthalten aber neben den nicht rostschutzfähigen Verunreinigungen stets unbeständiges Eisenoxydul gelöst, .und zwar in solchen Mengen, daß die Rostschutzfähigkeit der daraus hergestellten Pigmente in Frage gestellt ist.Attempts have already been made to `` melt ferrous, impure raw materials, such as natural iron ores, limonites and pyrite abbrarides, Mixtures of iron parts with iron oxide;: iron oxides with excess oxide, or of iron salts, e.g. B. waste salts, also of iron alloys or by To produce iron oxides contaminated with lime, rust protection pigments. Such melts however, in addition to impurities that cannot be protected against rust, they always contain something inconsistent Iron oxide dissolved, and in such quantities that the rust preventive properties of the pigments produced therefrom is in question.
Man hat auch schon Hammerschlag, wie er in den Eisenwerken beispielsweise an den Walzen als Walzenzunder abfällt, =geinählen: den üblichen Bindemitteln als Pigment zugesetzt. Abgesehen davon, däß der Walzsinter stets feine metallische Eisensplitter, die vom mechanischen Arbeitsprozeß herrühren, beigemischt enthält und diese Beimischung in der frisehen Ölfarbe bald verrostet und nach dem Auftrocknen eine vorzeitige =Zerstörung der Farbhaut herbeiführt, findet sich in dem Walzsinter auch immer überschüssiges unbeständiges Oxydul, weil die durch Verbrennen an der Oberfläche- des Eisenwerkstückes beim schnellen Durchgang durch die Walze gebildete Oxydkruste nicht Zeit findet, sich mit Sauerstoff vollkommen zu sättigen.You already have a hammer blow, as it is in the ironworks, for example falls on the rollers as roller scale, counting: the usual binders as Pigment added. Apart from the fact that the roll sintering process is always fine metallic iron splinters, which originate from the mechanical work process, contains admixed and this admixture soon rusted in the fresh oil paint and premature after drying = Causes destruction of the paint skin, there is always excess in the roll sinter unstable oxide, because of burning on the surface of the iron workpiece Oxide crust formed during rapid passage through the roller does not find time, to saturate oneself completely with oxygen.
Wie Versuche zeigten, die zur Erfindung geführt haben, lassen sich diese Übelstände vermeiden und Röstschutzfarben mit vorzüglichen Eigenschaften gewinnen,- wenn man als Pigment einen Körper verwendet, der durch Glühen von Eisenoxyden, insbesondere von Eisenhammerschlag, bei 75o bis zzoo° C in sauerstoffhaltiger Atmosphäre gewonnen wird. Bei dieser Behandlung der Eisenoxyde bildet sich eine graue, gesinterte, feinpulvrige Eisensauerstoffverbindung von der Formel Fe203 von hervorragender chemischer Beständigkeit, die sich dadurch erklären dürfte, daß die amorphen Oxyde durch die oxydische Glühung in den kristallinischen Zustand übergeführt werden.As experiments have shown that led to the invention, can avoid these evils and win anti-roasting colors with excellent properties, if a body is used as a pigment that is produced by glowing iron oxides, in particular from iron hammer blow, extracted at 75o to zoo ° C in an oxygen-containing atmosphere will. During this treatment of the iron oxides, a gray, sintered, finely powdered form is formed Iron-oxygen compound of the formula Fe203 with excellent chemical resistance, which can be explained by the fact that the amorphous oxides are caused by the oxidic annealing be converted into the crystalline state.
Man hat zwar schon Eisenzunder einer ' Weitereh - Behandlung unterworfen, indem man ihn geglüht, dann gesiebt und hierauf magnetisch aufbereitet hat. Bei dieser Behandlung entstand ein reines Oxyduloxyd, das im wesentlichen der Formel Fes 04 ent-. spricht. Das graue ferromagnetische Fee O@ @' der Erfindung ist also bei dieser BehandluF'rg' nicht gewonnen worden. Der Zweck der BeG; arbeitung war auch ein ganz anderer als bei der vorliegenden Erfindung, nämlich das im Oxydgehalt einheitliche Eisenoxyduloxyd als Bestandteil des Termits besser verwendbar zu machen. Die besonderen Vorteile, welche das graue Eisenoxyd der Erfindung bei der Verwendung als Rostschutzmittel besitzt, sind also durch die älteren Arbeiten nicht bekanntgeworden.Iron scale has already been subjected to a further treatment, by doing it is annealed, then sieved and then magnetically processed Has. During this treatment a pure oxide of oxide was produced, which is essentially the Formula Fes 04 developed. speaks. The gray ferromagnetic fairy O @ @ 'of the invention was therefore not won in this treatment. The purpose of the BeG; work was also quite different from the present invention, namely that of the oxide content to make uniform iron oxide more usable as a component of termite. The particular advantages of using the gray iron oxide of the invention as an anti-rust agent, have therefore not become known through the older work.
Das gemäß der Erfindung gewonnene Rostschutzmittel hat die Eigenschaft, sich durch andere hochwertige bunte Rostschutzpigmente leicht färben zu lassen; beispielsweise ergeben geringe Zusätze von Titan-, Blei- oder Zinkweiß, Chromgrün, Berlinerblau, Eisenrot und anderen Rostschutzpigmenten entsprechend gefärbte, lichtechte, bunte Mischpigmente. Diese verbilligten Rostschutzpigmente besitzen, mit den üblichen Bindemitteln zu Rostschutzfarben fertiggestellt, alle rostschützenden Vorzüge ihrer Mischkomponenten. Beispielsweise wird die Seifenbildung der basischen Bleifarbenzusätze mit den Fettsäuren der Bindeöle durch den erfindungsgemäß zu verwendenden Oxydkörper nicht gestört; anscheinend wirkt sich der Ferromagnetismus des-erfindungsgemäß zu verwendenden Oxydkörpers in der fertigen Farbe beim Anstreichen von Eisenkörpern noch derart aus, daß die gröberen Pigmentteilchen der Farbe zunächst am stärksten von der Eisenunterlage angezogen werden; erst dann legen sich die feineren in die Zwischenräume der gröberen hinein, wodurch eine äußerst dichte Schutzhaut entsteht.The rust inhibitor obtained according to the invention has the property to be easily colored by other high-quality colored rust protection pigments; for example, small additions of titanium, lead or zinc white, chrome green, Prussian blue, iron red and other anti-rust pigments appropriately colored, lightfast, colorful mixed pigments. These cheaper anti-rust pigments have the usual ones Binders for anti-rust paints completed, all their anti-rust benefits Mixed components. For example, the soapy of the basic lead paint additives with the fatty acids of the binding oils through the oxide body to be used according to the invention not bothered; apparently the ferromagnetism of the invention affects using oxide body in the finished paint when painting iron bodies still in such a way that the coarser pigment particles of the color are initially strongest be attracted to the iron pad; only then do the finer ones lay down in the Gaps between the coarser ones, creating an extremely dense protective skin.

Die besonderen Vorzüge des grauen erfindungsgemäß zu verwendenden Feq03 werden durch zahlreiche Beobachtungen belegt. Dieses Oxyd besitzt, verglichen mit anderen Eisenoxyden, ein besonderes Haftvermögen auf der Unterlage, eine geeignetere Dichte und eine schnellere Trockenzeit. Seine leichte Färbbarkeit mit anderen bunten hochwertigen Rostschutzfarbstoffen und die Möglichkeit, auf diese Weise neue farbtechnische Wirkungen hervorzubringen, ergibt sich aus dem Vergleich mit dem aus Lösungen chemisch gefällten Eisenoxydschwarz, dessen Färbekraft um 25mal größer ist als diejenige der mit dem grauen Eisenoxyd der Erfindung hergestellten Rostschutzfarbe. Infolgedessen läßt sich beispielsweise auf besonders einfachem und sparsamem Wege eine Mischfarbe mit Chromgrün herstellen. Besonders vorteilhaft ist auch die Duellzahl des erfindungsgemäßen Rostschutzmittels, die erheblich günstiger liegt als diejenige der mit dem ungeglühten Hammerschlag oder dem aus Lösungen gefällten Eisenoxydschwarz hergestellten Rostschutzfarbe.The particular advantages of gray to be used according to the invention Feq03 are proven by numerous observations. This oxide possesses compared with other iron oxides, a special adhesion to the base, a more suitable one Density and a faster drying time. Its easy dyeability with other brightly colored high-quality anti-rust dyes and the possibility of creating new technical colors in this way Producing effects results from a comparison with that from solutions chemically precipitated iron oxide black, the coloring power of which is 25 times greater than that the anti-rust paint made with the gray iron oxide of the invention. Consequently For example, a mixed color can be created in a particularly simple and economical way Make with chrome green. The duel number of the invention is also particularly advantageous Rust preventive, which is considerably cheaper than the one with the unannealed Hammer blow or the rust protection paint made from solutions precipitated iron oxide black.
