Der Gehalt an festem Schmiermittel in der Behandlungs flüssigkeit beträgt 50 bis 400 g/l, vorzugsweise 100 bis 150 g/l. Ein Gehalt von geringer als 50 g/l ergibt keine ausreichende Bildung einer festen Schmierschicht auf der metallischen Materialoberfläche, und wenn der Gehalt höher als 400 g/l ist, wird aufgrund einer übermäßigen Addition der Schmiereffekt gesättigt, so daß keine wei tere Verbesserung des Schmiereffekts erhalten wird und die Kosten der wäßrigen Schmierflüssigkeit erhöht werden.The content of solid lubricant in the treatment liquid is 50 to 400 g / l, preferably 100 to 150 g / l. A content of less than 50 g / l gives no sufficient formation of a solid smear layer on the metallic material surface, and when the content higher than 400 g / l is due to excessive Addition of the lubricating effect saturated, so that no white tere improvement of the lubricating effect is obtained and the cost of the aqueous lubricating fluid can be increased.
In die wäßrige Schmierbehandlungsflüssigkeit der Erfin dung wird ein oberflächenaktives Mittel zur Dispersion eines festen Schmiermittels in Wasser zugegeben, und es besteht keine spezielle Einschränkung hinsichtlich dessen Typs. Oberflächenaktive Mittel, wie sie im allgemeinen verwendet werden, umfassen oberflächenaktive Mittel vom nicht-ionischen Typ, z. B. Polyoxyethylen-alkylether, Poly oxyethylen-alkylphenylether, Polyoxyethylen-alkylester und Polyoxyethylen-sorbitanalkylester; oberflächenaktive Mittel vom anionischen Typ, z. B. Fettsäuresalze, Alkyl sulfate, Alkylsulfonat-alkylphosphate und Alkyldithio phosphate; oberflächenaktive Mittel vom kationischen Typ, z. B. aliphatische Aminsalze und quaternäre Ammonium salze; und oberflächenaktive Mittel vom amphoteren Typ, z. B.

In the aqueous lubrication treatment liquid of the inventions Formation becomes a surfactant for dispersion added a solid lubricant in water, and it There is no specific limitation on this Type. Surface-active agents, as they are in general used include surfactants of non-ionic type, e.g. For example, polyoxyethylene alkyl ethers, poly oxyethylene-alkylphenyl ether, polyoxyethylene-alkylester and polyoxyethylene sorbitan alkyl esters; surfactants Anionic type agent, e.g. B. fatty acid salts, alkyl sulfates, alkyl sulfonate alkyl phosphates and alkyl dithio phosphates; cationic type surfactants, z. As aliphatic amine salts and quaternary ammonium salts; and amphoteric type surfactants, z. B. Carboxylic acid salts of the amino acid type and the betaine Type, Sulfuric acid ester salts, Sulfonsäureestersalze and Phosphorsäureestersalze.
Der Gehalt an oberflächenaktivem Mittel in der wäßrigen Schmierflüssigkeit der Erfindung beträgt 1 bis 40 g/l, vorzugsweise 5 bis 10 g/l. Der Gehalt an oberflächenakti vem Mittel wird vorzugsweise in Abhängigkeit von Gehalt an festem Schmiermittel erhöht oder erniedrigt. Ist der Gehalt des oberflächenaktiven Mittels geringer als 1 g/l, wird das feste, oberflächenaktive Mittel in der Behand lungsflüssigkeit unzureichend benetzt, und eine größere Menge als 40 g/l erhöht nicht den Effekt des oberflächen aktives Mittels in signifikantem Ausmaß.The content of surface-active agent in the aqueous Lubricating fluid of the invention is 1 to 40 g / l, preferably 5 to 10 g / l. The content of surface acti The agent is preferably dependent on the content increased or decreased in solid lubricant. Is the Content of surfactant less than 1 g / l, is the solid surfactant in the treat insufficiently wetted, and a larger one Quantity than 40 g / L does not increase the effect of the surfaces active agent to a significant extent.

Der Gehalt an kolloidalem Titan in der wäßrigen Schmierflüs sigkeit beträgt 10 ppm oder mehr, ausgedrückt als Titan, vorzugsweise 50 ppm oder mehr. Ist der Gehalt an kol loidaler Titanverbindung geringer als 10 ppm, ist die Schmierfähigkeit durch deren Zugabe wenig verbessert, und ist der Gehalt höher als 10 ppm, wird die Wirkung im Hinblick auf die Schmierfähigkeit der wäßrigen Schmier flüssigkeit mit zunehmendem Gehalt an kolloidaler Titan verbindung erhöht. Demzufolge besitzt der Gehalt an kol loidaler Titanverbindung in der wäßrigen Schmierflüssig keit der Erfindung keine spezifische obere Grenze. Es ist möglich, den Gehalt auf ein Niveau zu erhöhen, das so hoch ist, wie es für die Herstellung der wäßrigen Schmierbehandlungsflüssigkeit erforderlich ist. As for the aqueous lubricating fluid of the invention The colloidal titanium compound used can be cloudy or cloudy solution, obtained by neutralization of a Compound of sulfuric acid with titanium or phosphoric acid with titanium, with z. B. caustic soda or caustic soda or sodium hydroxide or the like., Can be used. The Content of colloidal titanium in the aqueous lubricating liquid is 10 ppm or more in terms of titanium, preferably 50 ppm or more. Is the content of col loidal titanium compound less than 10 ppm, is the Lubricity is little improved by their addition, and if the content is higher than 10ppm, the effect will be in With regard to the lubricity of the aqueous lubricants liquid with increasing content of colloidal titanium increased connection. Consequently, the content of col loidal titanium compound in the aqueous lubricating fluid of the invention no specific upper limit. It is possible to raise the salary to a level that is as high as it is for the production of the aqueous Lubricating fluid is required.
Es ist auch möglich, die wäßrige Schmierbehandlungsflüssig keit der Erfindung unter bzw. nach Zugabe eines Ent schäumungsmittels und/oder von Rostverhinderungsadditiven etc. zu verwenden.It is also possible to use the aqueous lubricating treatment liquid keit of the invention under or after addition of an Ent foaming agent and / or rust inhibiting additives etc. to use.

Es gibt weiterhin keine spezielle Einschränkung hinsicht lich der organischen Bindemittel, vorausgesetzt, daß sie für den Zweck der Erfindung wirksam sind. Bekannte Bin demittel können verwendet werden, vorzugsweise jedoch wird eine wasserlösliche Verbindung mit hohem Molekular gewicht eingesetzt. Diese Verbindungen umfassen natürli che Substanzen mit hohem Molekulargewicht, wie Stärke, Tang bzw. Seetang bzw. Seegras, pflanzliches Mucilago bzw. Pflanzenschleim, tierisches Protein und Fermenta tionsmucilago; halb-synthetische Substanzen mit hohem Molekulargewicht, erhältlich aus Stärke, Cellulose und dergl., und synthetische Polymere, wie PVP, PEG und PVA.There is no special restriction the organic binders, provided that they are are effective for the purpose of the invention. Known bin may be used, but preferably becomes a water soluble high molecular compound weight used. These compounds include naturli high molecular weight substances, such as starch, Seaweed or seaweed, vegetable mucilage or vegetable mucus, animal protein and fermenta tionsmucilago; semi-synthetic substances with high Molecular weight, available from starch, cellulose and and the like, and synthetic polymers such as PVP, PEG and PVA.
Der Gehalt an vorstehend genanntem Bindemittel als Kom ponente in der wäßrigen Schmierbehandlungsflüssigkeit der vorliegenden Erfindung beträgt 5 bis 150 g/l, vor zugsweise 10 bis 50 g/l. Der Gehalt wird gewöhnlich ent sprechend dem Gehalt des festen Schmiermittels festge legt. Beträgt der Gehalt der Bindemittelkomponente weni ger als 5 g/l, ist die Bindung der festen Schmierschicht an die Oberfläche des metallischen Materials unzurei chend, und überschreitet der Gehalt 150 g/l, wird keine zusätzlich verstärkte Bindung zwischen der festen Schmier schicht und der Oberfläche des metallischen Materials erzielt. Im Gegensatz kann im letztgenannten Fall die wäßrige Schmierflüssigkeit eine übermäßig hohe Viskosi tät ergeben, was zu einer übermäßigen Abscheidung der festen Schmierschicht auf der Oberfläche des metalli schen Materials führt und somit ein Verstopfen der Form bzw. der Matrize verursacht.The content of the above-mentioned binder as Kom component in the aqueous lubrication fluid The present invention is 5 to 150 g / L, before preferably 10 to 50 g / l. The content is usually ent according to the content of the solid lubricant sets. If the content of the binder component is less greater than 5 g / l, is the bond of the solid lubricating layer to the surface of the metallic material ing, and the content exceeds 150 g / l, none will additionally reinforced bond between the solid lubricants layer and the surface of the metallic material achieved.
