Description

Verfahren zur Herstellung von rostschützenden Anstrichmitteln. Schwefelhaltige Rostschutzmittel sind seit langem bekannt und wegen ihrer rostschützenden Eigenschaften vielfach verwendet. So wird z. B. nach Patentschrift 299904 ein fettes Öl mit Harz gemischt, mit Schwefel erhitzt, ferner nach Patentschrift 122688 Chlorschwefel auf Fettgasteer einwirken gelassen. Alle diese Verfahren gehen zunächst davon aus, daß durch Einwirkung von Schwefel bzw. Chlorschwefel, Fette, Öle, teerartige Produkte usw. eine Molekular-Kondensation unter Austritt von Schwefelwasserstoff stattfindet. Bei diesen Verfahren wird der Schwefel teilweise zu Schwefelwasserstoff reduziert, teils bleibt er zu einem geringen Prozentsatz chemisch gebunden.Process for the production of anti-rust paints. Sulfur-containing rust inhibitors have been known for a long time and are widely used because of their rust-preventing properties. So z. B. according to patent specification 299904 a fatty oil mixed with resin, heated with sulfur, also allowed chlorine sulfur to act on Fettgasteer according to patent specification 122688. All of these processes start from the assumption that the action of sulfur or chlorosulfur, fats, oils, tar-like products, etc., results in molecular condensation with the escape of hydrogen sulfide. In this process, the sulfur is partially reduced to hydrogen sulfide, while a small percentage remains chemically bound.

Gegenstand der vorliegenden Erfindung ist nun, Schwefel in chemisch leicht reagierender Form auf das zu schützende Eisen usw. derart einwirken zu lassen, daß sich eine Schicht von Schwefeleisen und organischen Sulfiden bildet, welche gegen chemische Einflüsse weitgehend beständig ist. Als Schwefelübertrager bedient sich das vorliegende Verfahren der Anilinholysulfide oder dessen Homologen, welche Schwefel in leicht abspaltbarer Form enthalten (s. K. A. Hofmann, Bericht der Deutschen Chemischen -Gesellschaft 27, S. 2807) und am einfachsten durch Erhitzen von Anilin mit einer in bezug auf die Thioanilinbildung überschüssigen Schwefelmenge dargestellt werden. Bringt man diese in geeigneter Weise mit künstlichen oder natürlichen Asphalten mit oder ohne Zusatz von Harz, trocknenden Ölen usw. zusammen, so verbindet sich bei gelindem Erwärmen oder längerem Stehen der Lösungen ein Teil des Schwefels mit dem Asphalt, während der Rest des Schwefels, welcher in reaktionsfähiger Form an das Anilin gebunden ist, sich beim Aufstreichen mit dem Eisen zu Schwefeleisen verbindet und dieses von den organischen Sulfiden geschützt wird.The present invention is now, sulfur in chemical easily reacting form to act on the iron to be protected etc. in such a way, that a layer of iron sulphide and organic sulphides is formed, which is largely resistant to chemical influences. Served as a sulfur transmitter the present process of the aniline holysulfide or its homologues, which Contains sulfur in an easily split off form (see K. A. Hofmann, Report of the Germans Chemischen -Gesellschaft 27, p. 2807) and the easiest way by heating aniline with an excess amount of sulfur in relation to thioaniline formation will. If you bring this in a suitable way with artificial or natural asphalt with or without the addition of resin, drying oils, etc. together, so connects when the solutions are gently heated or left to stand for a long time, some of the sulfur is added the asphalt, while the rest of the sulfur, which is in reactive form the aniline is bound, when it is spread it combines with the iron to form sulfuric iron and this is protected from the organic sulfides.

Beispiel: ioo g Petrolpech werden in 150 9 Benzol oder Benzin gelöst und zu der Lösung io g Polytio-Anilin gegeben. -Nach etwa achttägigem Stehen in verschlossenem Gefäß ist die Mischung, die hierbei etwas verdickt, streichfähig.Example: 100 g of petroleum pitch are dissolved in 150 g of benzene or gasoline and added 10 g of polytio-aniline to the solution. -After about eight days of standing in In a closed container, the mixture, which thickens a little, is spreadable.
