Definitions
- Brake fluids for motor vehicles are subject to very high requirements in terms of their chemical and physical properties. According to the existing standards and specifications for brake fluids from the US Department of Transportation in the Federal Motor Vehicle Safety Standard FMVSS No. 116 and the standard SAE J 1704 issued by the Society of Automotive Engineers, modern brake fluids should on the one hand have high dry boiling points (reflux boiling points, dry [Equilibrium reflux boiling point, "ERBP”]) and high wet boiling points (reflux boiling points, moist ["wet ERBP”]) have, on the other hand, also have a viscosity that changes only little within a wide temperature range.
- ERBP Equilibrium reflux boiling point
- 1H-1,2,3-triazoles such as 1H-1,2,3-benzotriazole or 1H-1,2,3-tolutriazole as corrosion inhibitors in hydraulic fluids or brake fluids has long been known, for example from EP-A 028 789 (1) and EP-A 454 110 (2).

Die nachfolgenden Beispiele sollen die vorliegende Erfindung erläutern, ohne sie zu beschränken.The following examples are intended to illustrate the present invention without restricting it.
Basierend auf den marktüblichen DOT 4- bzw. DOT 5.1-Bremsflüssigkeiten BF 1 (ERBP: 267°C, wet ERBP: 173°C, kinematische Viskosität bei -40°C: 676 cSt) und BF 2 (ERBP: 263°C, wet ERBP: 181°C, kinematische Viskosität bei -40°C: 850 cSt) mit jeweils 0,05 Gew.-% 1H-1,2,3-Tolutriazol als Buntmetallkorrosionsinhibitor wurden im Vergleich dazu die erfindungsgemäßen Bremsflüssigkeiten BF 1a, BF 1b, BF 1c und BF 2a geprüft.Based on the commercially available DOT 4 or DOT 5.1 brake fluids BF 1 (ERBP: 267 ° C, wet ERBP: 173 ° C, kinematic viscosity at -40 ° C: 676 cSt) and BF 2 (ERBP: 263 ° C, wet ERBP: 181 ° C, kinematic viscosity at -40 ° C: 850 cSt) with 0.05% by weight of 1H-1,2,3-tolutriazole as non-ferrous metal corrosion inhibitor in each case In comparison, the brake fluids BF 1a, BF 1b, BF 1c and BF 2a according to the invention were tested.
Die verwendeten Kraftfahrzeug-Bremsflüssigkeiten hatten folgende Zusammensetzungen:
Die erfindungsgemäßen Bremsflüssigkeiten BF 1a und BF 2a unterschieden sich von BF 1 und BF 2 nur dadurch, daß sie anstelle von 0,05 Gew.-% 1H-1,2,3-Tolutriazol die gleiche Menge an 1H-1,2,4-Triazol enthielten; die erfindungsgemäße Bremsflüssigkeit BF 1b enthielt anstelle von 0,05 Gew.-% 1H-1,2,3-Tolutriazol 0,04 Gew.-% 1H-1,2,4-Triazol und 0,01 Gew.-% Adenin; die erfindungsgemäße Bremsflüssigkeit BF 1c enthielt anstelle von 0,05 Gew.-% 1H-1,2,3-Tolutriazol 0,07 Gew.-% 1H-1,2,4-Triazol (dafür jedoch nur 54,98 Gew.-% Methyltriglykol-borat).The brake fluids BF 1a and BF 2a according to the invention differ from BF 1 and BF 2 only in that they contain the same amount of 1H-1,2,4 instead of 0.05% by weight of 1H-1,2,3-tolutriazole -Triazole contained; the inventive brake fluid BF 1b contained 0.04% by weight 1H-1,2,4-triazole and 0.01% by weight adenine instead of 0.05% by weight 1H-1,2,3-tolutriazole; the inventive brake fluid BF 1c contained 0.07% by weight 1H-1,2,4-triazole instead of 0.05% by weight 1H-1,2,3-tolutriazole (but only 54.98% by weight % Methyl triglycol borate).
Die anwendungstechnischen Untersuchungen wurden gemäß dem Kupferkorrosionstest PSA D 53 5387 in der Version des Jahres 2000 der Firma PSA Peugeot Citroën durchgefuhrt. Hierbei wird zuerst ein zuvor in Aceton gereinigtes Kupferblech mit einer Gesamtfläche von 1000 cm2 (Abmessungen: 71,4 cm x 7 cm x 0,05 cm) in Form eines Rundzylinders schneckenförmig so aufgerollt, daß sich die Metallfläche im Inneren nicht berührt. Das Kupferblech wird in eine Mischung aus 294 ml Bremsflüssigkeit mit 6 ml destilliertem Wasser gestellt und für 100 Stunden auf 100°C erhitzt; durch die Flüssigkeit werden pro Stunde 10 Liter Luft geleitet, die zuvor durch auf 2°C gekühltes destilliertes Wasser geleitet wurde. Nach dem Test wird das Aussehen des wieder aufgerollten Kupferbleches und das Aussehen der Flüssigkeit optisch beurteilt und der Kupfergehalt der Flüssigkeit ermittelt.The application-related investigations were carried out in accordance with the copper corrosion test PSA D 53 5387 in the 2000 version from PSA Peugeot Citroën. Here, a copper sheet previously cleaned in acetone with a total area of 1000 cm2 (dimensions: 71.4 cm x 7 cm x 0.05 cm) is rolled up in a spiral shape in the form of a round cylinder so that the metal surface inside does not touch. The copper sheet is placed in a mixture of 294 ml of brake fluid with 6 ml of distilled water and heated to 100 ° C. for 100 hours; 10 liters of air per hour, which had previously been passed through distilled water cooled to 2 ° C., are passed through the liquid. After the test, the appearance of the re-rolled copper sheet will be and the appearance of the liquid is visually assessed and the copper content of the liquid is determined.
Die Ergebnisse nach dem beschriebenen Test sind der nachfolgenden Tabelle 1 zu entnehmen.
Es wird ersichtlich, daß die erfindungsgemäßen Formulierungen im Gegensatz zu herkömmlichen Bremsflüssigkeiten wie BF 1 und BF 2 nicht nur einen sehr guten Kupferkorrosionsschutz mit geringem Cu-Gehalt in der Testflüssigkeit bieten, sondern zusätzlich auch eine belagfreie Metalloberfläche und keine Sedimentbildung in der Bremsflüssigkeit bewirken.It can be seen that, in contrast to conventional brake fluids such as BF 1 and BF 2, the formulations according to the invention not only offer very good copper corrosion protection with a low Cu content in the test fluid, but also produce a coating-free metal surface and no sedimentation in the brake fluid.
Die nachfolgend aufgeführten Ergebnisse im Korrosionstest gemäß SAE J 1704 (Jan. 97) belegen außerdem, daß erfindungsgemäße Bremsflüssigkeiten wie BF 2a mit einem niedrigen 1H-1,2,4-Triazol-Gehalt im Vergleich zu nicht erfindungsgemäßen Formulierungen wie BF 1d mit einem hohen 1H-1,2,4-Triazol-Gehalt Vorteile bieten, da sie bei Kupfer ein besseres Korrosionsergebnis zeigen (BF 1d entsprach BF 1, enthielt anstelle von 1H-1,2,3-Tolutriazol jedoch 0,20 Gew.-% 1H-1,2,4-Triazol und nur 54,85 Gew.-% Methyltriglykol-borat):The results listed below in the corrosion test according to SAE J 1704 (Jan. 97) also show that brake fluids according to the invention such as BF 2a with a low 1H-1,2,4-triazole content compared to formulations not according to the invention such as BF 1d with a high 1H-1,2,4-triazole content offer advantages, since they show better corrosion results with copper (BF 1d corresponded to BF 1, but instead of 1H-1,2,3-tolutriazole contained 0.20% by weight of 1H -1,2,4-triazole and only 54.85% by weight methyl triglycol borate):
Die Ergebnisse nach dem Korrosionstest gemäß SAE J 1704 (Jan. 97) sind der nachfolgenden Tabelle 2 zu entnehmen.
