Description

Rostschutzmittel. Durch das Patent 313617 ist ein Verfahren zur Herstellung von. phosphorsäurehaltigen. Ölen und Fetten geschützt worden, bei dem Öle und Fette, die eine oder mehrere Hydroxylgruppen enthalten, so beispielsweise Rizinusöl, Traubenkernöl, Wollfett usw., mit Phosphorsäureanhydrid in der Kälte oder bei mäßiger Wärme behandelt werden.Anti-rust agents. By patent 313617 is a method of manufacture from. containing phosphoric acid. Oils and fats have been protected, in which oils and fats, which contain one or more hydroxyl groups, such as castor oil, grapeseed oil, Wool fat, etc., treated with phosphoric anhydride in the cold or in moderate heat will.

Es hat sich nun herausgestellt, daß die so erhaltenen Öle und Fette, die die Phosphorsäure in organisch gebundener Form enthalten, eine außerordentlich starke rostschützende Wirkung auf blankes Eisen ausüben, und zwar halben die vorgenommenen Versuche ergeben, daß die rostschützende Wirkung der Phosphorsäurehaltigen Öle und Fette diejenige der nicht mit Phosphorsäure behandelten Öle und Fette bei weitem übertrifft.It has now been found that the oils and fats thus obtained, which contain the phosphoric acid in organically bound form, an extraordinary one have a strong anti-rust effect on bare iron, half of what has been done Experiments show that the rust-preventing effect of the oils and phosphoric acid Fats by far that of the oils and fats not treated with phosphoric acid surpasses.

Beispielsweise zeigte -ein mit phosphoriertem Rizinusöl :behandeltes blankes Eisen, nachdem es drei Monate dauernd einer feuchten warmen Atmosphäre ausgesetzt war, noch seinen ursprünglichen. Glanz, während andere unter denselben Bedingungen ausgelegte Eisenteile, die mit gewöhnlichem Rizinusöl; Leinölfirnis, Vaseline und verschiedenen Rostschutzmitteln des Handels behandelt worden waren., schon nach wenigen Tagen Rost ansetzten und nach drei Monaten fast vollkommen verrostet _ waren.For example, showed -ein with phosphorus castor oil: treated bare iron after being exposed to a warm, humid atmosphere for three months was still its original. Shine while others under the same conditions laid out iron parts made with common castor oil; Linseed oil varnish, petroleum jelly and various rust inhibitors of the trade had been treated., already after rusted in a few days and after three months they were almost completely rusted.

Die rostschützende Wirkung der phosphorierten Öle und Fette ist so intensiv, @daß eine fast unsichtbare dünne Schicht dieser öle und Fette auf dem Eisen, wie man sie .erhält, wenn man die öle oder Fette mit einem Polierbausch dünn aufreibt, genügt, um einen vollkommenen Rostschutz zu erzielen.The rust-protecting effect of the phosphorous oils and fats is like that intense, @ that an almost invisible thin layer of these oils and fats on that Iron as you can get it if you thin the oils or fats with a polishing pad rubs, is sufficient to achieve complete rust protection.

Die neuen Rostschutzmittel können auch mit flüchtigen Lösungsmitteln, wie z. B. Benzol oder Spiritus; verdünnt angewendet werden. Auch. wird die rostschützende Wirkung anderer 61e und Fette sowie diejenige von -Lacken und Ölfarben, und schließlich diejenige anderer Rostschutzmittel durch Zusatz einiger Prozente der pbosphorierten Öle wesentlich erhöht.The new anti-rust agents can also be used with volatile solvents, such as B. Benzene or alcohol; can be used diluted. Even. becomes the anti-rust Effect of other oils and fats as well as that of lacquers and oil paints, and finally that of other anti-rust agents by adding a few percent of the phosphorous Oils significantly increased.

Es ist bereits vorgeschlagen worden; Gemische von Ölen mit Säuren als Rostschutzmittel zu verwenden. Hierbei muß aber die Säure auf das Metall schädigend einwirken. Bei dem vorstehenden Verfahren handelt es sich nicht um Gemenge von Ölen mit freier Phosphorsäure, sondern um Öle, in denen die Phosphorsäure organisch gebunden ist, so daß sie selbst beim Kochen. mit Salzsäure nicht vollkommen daraus abgespalten werden kann.It has already been suggested; Mixtures of oils with acids to be used as a rust preventive. Here, however, the acid must be damaging to the metal act. The above process is not a mixture of oils with free phosphoric acid, but with oils in which the phosphoric acid is organically bound is so that they can cook by themselves. not completely split off from it with hydrochloric acid can be.

Die starke rostschützende Wirkung der phosphorierten Öle ist anscheinend darauf zurückzuführen, daß die Öle mit dem Eisen eine chemische Verbindung eingehen, die das Eisen in Form einer wasserabstoßenden, für Sauerstoff und Kohlensäure, undurchlässigen Schicht bedeckt. Das mit den neuen Ölen behandelte Eisen wird auch dann noch vor Rost geschützt, wenn man die auf dem Eisen aufliegende sichtbare Ölschicht mehrere Stunden nach dem Auftragen des phosphorierten Öles mit Benzin entfernt.The strong anti-rust effect of the phosphorous oils is apparent due to the fact that the oils form a chemical bond with the iron, which the iron in the form of a water-repellent, impermeable to oxygen and carbonic acid Layer covered. The iron treated with the new oils will still be present Rust protected when you look at the one resting on the iron visible Oil layer several hours after applying the phosphorous oil with gasoline removed.
