Die Erfindung betrifft Bremsflüssigkeiten mit einem Gehalt an Fettsäuren.
5The invention relates to brake fluids containing fatty acids.

Handelsüblichen Bremsflüssigkeiten, die den US-Normen des Federal Motor Vehicle Safety Standard FMVSS 116, DOT 3 bzw. _ des Handbook of the Society of Automotive Engineers SAE J 1703 entsprechen, bestehen im wesentlichen aus: Glkyoläthern als Basiskomponenten, Polyglykolen als -Schmiermittelkomponenten und enthalten Inhibitoren zwecks Korrosionsschutz und Antioxidationsmittel.Commercially available brake fluids that meet the US standards of the Federal Motor Vehicle Safety Standard FMVSS 116, DOT 3 or _ of the Handbook of the Society of Automotive Engineers SAE J 1703 consist essentially of: Glycol ethers as basic components, polyglycols as lubricant components and contain inhibitors for the purpose of corrosion protection and antioxidants.

Diese DOT-3-Bremsflüssigkeiten weisen im allgemeinen guten Korrosionsschutz gegenüber Weißblech, Stahl, Grauguß, Messing, Kupfer und Aluminium auf. Der Korrosionsschutz ist jedoch nur dann gewährleistet, wenn die Metalle vollständig in die Flüssigkeit eingetaucht werden oder sonst von ihr gut benetzt werden.
20These DOT-3 brake fluids generally have good corrosion protection against tinplate, steel, gray cast iron, brass, copper and aluminum. Corrosion protection is only guaranteed if the metals are completely immersed in the liquid or otherwise well wetted by it.

Un Bremsteile, Insbesondere Radbremszylinder aus Grauguß, nach der Herstellung und Funktionsprüfung rostfrei lagern zu können, ist die Imprägnierung mit speziellen Bremspasten üblich.
25In order to be able to store brake parts, in particular wheel brake cylinders made of gray cast iron, in a rust-free manner after production and functional testing, impregnation with special brake pastes is common.

Ein wesentlicher Nachteil dieser Bremspasten besteht darin,A major disadvantage of these brake pastes is that they

Derartige Mischungen erfüllen dann nicht mehr die Anforderungen der FMVSS 116, DOT 3.significantly increase accuracy, the viscosity, so that the viscosity of the filled fluid may substantially exceeds / the maximum viscosity of 1500 cSt at 0 C -'40. Such mixtures then no longer meet the requirements of FMVSS 116, DOT 3.

Es bestand daher die.Aufgabe, Bremsflüssigkeiten vorzuschlagen, die gleichzeitig zur Imprägnierung verwendet werden können und die die Lagerung der Bauteile über längere Perioden ohne Korrosion ermöglichen.The task was therefore to propose brake fluids, which can be used for impregnation at the same time and which store the components for longer periods allow without corrosion.

. ■■ Allein die Erhöhung der Inhibitorkonzentration bzw. die Verwendung anderer Inhibitoren, z.B. von Fettsäuren kann zwar die korrosionsschützende Wirkung auf den benetzten Teil erhöhen. Man erhält aber nicht Flüssigkeiten die den Anforderungen, die an Bremsenschutzflüssigkelten gestellt werden, entsprechen. Außerdem kann man die Konzentration der Fettsäuren oder Fettsäurederivate nur geringfügig steigern, weil diese Komponenten bei tiefer Temperatur zur Ausfällung neigen bzw. erhöhte Gummiquellung der SBR-Manschetten verursachen.. ■■ Just increasing the inhibitor concentration or the The use of other inhibitors, e.g. fatty acids, can reduce the anti-corrosive effect on the wetted Increase part. But you do not get fluids that meet the requirements placed on brake protection fluids will correspond. You can also get the concentration Increase the number of fatty acids or fatty acid derivatives only slightly, because these components cause precipitation at low temperatures tendency or increased rubber swelling of the SBR sleeves cause.

Es wurde nun überraschenderweise gefunden, daß Bremsflüssigkeiten auf der Grundlage von Polyglykoläthern als Baslskomponenten, Polyglykolen als Schmiermittelkomponenten, Inhibitoren und Antioxydationsmittel der genannten Forderung genügen, wenn sie einen Gehalt vonIt has now surprisingly been found that brake fluids based on polyglycol ethers as base components, Polyglycols as lubricant components, inhibitors and antioxidants meet the stated requirement, if they have a salary of

Die hochmolekularen Polyalkylenglykole sind dabei Trägersubstanzen, die geringe Wasserlöslichkeit aufweisen und durch hohe Llpophllität gekennzeichnet sind. Dadurch können sie die Fettsäuren vermehrt lösen, so daß die Konzentration der Fettsäuren bis zu 3 % in der Bremsflüssigkeit betragen kann.The high molecular weight polyalkylene glycols are carrier substances which have low solubility in water and are characterized by high propensity. This allows them to dissolve the fatty acids more, so that the concentration of the fatty acids in the brake fluid can be up to 3%.

Die erfindungsgemäß in den Bremsflüssigkeiten enthaltenen Polyalkylenglykole der Formel I können durch allein aus Polypropylenglykolen bestehen, durch Mischen von vorwiegend Polypropylenglykolen mit Polyäthylenglykolen oder durch Umsetzen von Gemischen von Äthylenoxid und (in Überschuß) ?ropylenoxid hergestellt werden, wobei statistische Gemische von Verbindungen entstehen, die im Mittel mehr Propylenoxid als Äthylenoxidreste enthalten und Molekulargewichte in dem angegebenen Rereich aufweisen.The polyalkylene glycols of the formula I contained in the brake fluids according to the invention can consist solely of polypropylene glycols, by mixing predominantly polypropylene glycols with polyethylene glycols, or by reacting mixtures of ethylene oxide and (in excess) propylene oxide, with random mixtures of compounds being produced in the Average contain more propylene oxide than ethylene oxide residues and have molecular weights in the specified range.

Zur Untersuchung der imprägnierenden Wirkung der erfindungs*- gemäßen Bremsflüssigkeiten werden Radbremszylinder aus Grauguß längsseitig halbiert, mit Isopropanol gereinigt und gut getrocknet. Man taucht dann den halbierten Bremszylinder jeweils 5 Sekunden in die handelsübliche Bremsflüssigkeit bzw. in die Bremsflüssigkeiten mit verbessertem Korrosionsschutz ein, läßt 5 Sekunden abtropfen und lagert sie in einem geschlossenen Gefäß über einer wasserdampfgesättigten Atmosphäre. Hierbei zeigt sich, daß bei Verwendung handelsüblicher Bremsflüssigkeiten bereits nach wenigen Stunden ein starkes Rosten der Graugußteile beobachtet werden kann. Bei den erfindungsgemäßen Flüssigkeiten wird hingegen der Ansatz von Rost, selbst nach einer Lagerung von 30 Tagen über der wasserdampfgesättigten Atmosphäre bei Raumtemperatur vermieden.To investigate the impregnating effect of the invention * - In accordance with brake fluids, wheel brake cylinders made of gray cast iron are halved lengthways, cleaned with isopropanol, and good dried. The halved brake cylinder is then immersed in the commercially available brake fluid for 5 seconds or in the brake fluids with improved corrosion protection, lets them drip off for 5 seconds and stores them in a closed vessel over an atmosphere saturated with water vapor. This shows that when using commercially available With brake fluids, severe rusting of the gray cast iron parts can be observed after just a few hours. In the case of the liquids according to the invention, on the other hand, rust builds up even after storage for 30 days Avoided above the water vapor-saturated atmosphere at room temperature.
