 und Lagerdauer, blank zu erhalten. Das Verfahren besteht darin, Kumaronharzlösungen, das sind   Waschverlustrückstände,   bei der   Steinkohlenteer-Leichtöl-Aufbereitung   mit Formaldehyd und mit ganz geringen Mengen von Ammoniak unter   möglichster   Befreiung von jedem Wassergehalt zu versetzen, 
 EMI1.2 
 6 bis 9% Formaldehyd und   0'1   bis   0-2% Ammoniak ergibt.   



   Die Anwendung erfolgt bei Walzgut in der Weise, dass dieses möglichst unmittelbar nach dem Walzvorgang, also noch bei entsprechend hoher Temperatur, den Auftrag der Mischung erfährt. Es   genÜgt   aber auch, das Halbgut oder das Fabrikat mit der Mischung zu bestreichen. 



   Nach dem Auftragen der   Kumaronmischung   wird das   Werkstück   mit einem Überzug von Paraffin od. dgl. versehen. Bekanntlich wurde Paraffin allein schon als Rostschutzmittel verwendet, doch hat es sich aus dem Grunde nicht bewähren können, weil es nicht auf der   Eisen-oder Stahlunterlage haftet,   sondern blasig aufzustehen und zu reissen pflegt. Die Adhäsion zwischen Paraffin od. dgl. und der Kumaronmischung ist dagegen eine so bedeutende, dass hier ein Loslösen völlig hintangehalten wird. 



  Zudem wirkt der Paraffinaufstrich glättend und wasserabweisend. 



   Bleche werden zweckmässig so behandelt, dass man sie nach dem Walzen eine   Vierfachwatzenstrasse   passieren lässt, deren erstes und drittes Walzenpaar die   Kumaronmischung   bzw. Paraffin od. dgl. aufbringen, während die zweiten und vierten Walzenpaare die Glättung des Auftrages bewirken. Derartig präparierte Bleche bedürfen unter Umständen keiner Dekapierung.

  A method for producing a rust preventive and treating iron and steel with this rust preventive.
 EMI1.1
 and storage time to be kept blank. The process consists in adding formaldehyde and very small amounts of ammonia to coumarone resin solutions, i.e. residues from washing losses, with formaldehyde and very small amounts of ammonia with the greatest possible freedom from any water content,
 EMI1.2
 Gives 6 to 9% formaldehyde and 0.1 to 0-2% ammonia.



   In the case of rolling stock, it is used in such a way that the mixture is applied as soon as possible after the rolling process, i.e. still at a correspondingly high temperature. But it is also sufficient to coat the semi-finished product or the product with the mixture.



   After applying the coumarone mixture, the workpiece is covered with paraffin or the like. As is well known, paraffin alone has already been used as a rust preventive, but it has not been able to prove itself for the reason that it does not adhere to the iron or steel base, but tends to stand up in blisters and tear. The adhesion between paraffin or the like and the coumaron mixture, on the other hand, is so important that detachment is completely prevented.



  In addition, the paraffin spread has a smoothing and water-repellent effect.



   Sheets are expediently treated in such a way that, after rolling, they are allowed to pass through a quadruple roller line, the first and third roller pairs of which apply the coumarone mixture or paraffin or the like, while the second and fourth roller pairs smooth the job. Sheets prepared in this way may not require picking.



   PATENT CLAIMS:
1. A method for producing a rust preventive, characterized in that coumarone resin solutions are mixed with formaldehyde and small amounts of ammonia with the greatest possible freedom from any water content, so that there is a possible ratio for the anhydrous end product
