Die Erfindung bezieht sich auf hydraulische Bremsflüssigkeiten. The invention relates to hydraulic brake fluids.
Es sind bereits hydraulische Flüssigkeiten bekannt, die aus Additionsprodukten von Alkylenoxyden und Rizinusöl bestehen und ebenfalls die erfindungsgemäß verwendeten Verdünnungsmittel enthalten. Bei diesen hydraulischen Bremsflüssigkeiten ist jedoch das Verhältnis von Rizinusöl und Alkylenoxyd in den entsprechenden, nicht flüchtigen Additionsprodukten verschieden von dem erfindungsgemäßen Verhältnis. Dieses Verhältnis ist jedoch entscheidend, und die bekannten Produkte bestehen daher ofen Wassertoleranztest von SAE 70 R 1 bzw. den Verdampfungstest von SAE 70 R 1 bzw. den Flammpunkttest von SAE 70 R 1 nicht. Diese Teste werden durch die neuen hydraulischen Bremsflüssigkeiten jedoch erfüllt. Die neuen hydraulischen Bremsflüssigkeiten bestehen größtenteils auch die schärferen Standardbestimmungen von SAE 70 R 3.There are already hydraulic fluids known from the addition products of alkylene oxides and There are castor oil and also contain the diluents used according to the invention. With these hydraulic brake fluids, however, the ratio of castor oil and alkylene oxide in the corresponding non-volatile addition products is different of the ratio according to the invention. However, this ratio is crucial and the known products therefore pass the water tolerance test of SAE 70 R 1 or the evaporation test of SAE 70 R 1 or the flash point test of SAE 70 R 1 not. However, these tests are met by the new hydraulic brake fluids. the The new hydraulic brake fluids also largely comply with the stricter standard provisions from SAE 70 R 3.
Der Versuch gemäß den Standardbestimmungen SAE 70 R 1 ist der folgende:The test according to the standard regulations SAE 70 R 1 is the following:
Es sollen zwei 100 ccm-Proben der Flüssigkeit mit jeweils 3,5 ecm destilliertem Wasser vermischt werden. Eine Probe soll 24 Stunden auf einer Temperatur von 6O0C und die andere 24 Stunden auf — 400C gehalten werden, und beide Proben sollen auf Schichtung und Ausfällung untersucht werden. Nach Ablauf der 24 Stunden soll die auf — 400C gehaltene Flasche aus der senkrechten in die waagerechte Lage gekippt werden, und die Masse soll innerhalb von 5 Sekunden zu fließen beginnen.Two 100 ccm samples of the liquid are to be mixed with 3.5 ecm of distilled water each. A sample to 24 hours at a temperature of 6O 0 C and 24 hours on the other - to be kept 40 0 C, and both samples are to be examined for stratification and precipitation. Bottle held 40 0 C from the vertical to be tilted in the horizontal position, and the mass is to start flowing within 5 seconds - after expiry of the 24 hours, the on to.
Ziel der Erfindung ist die Schaffung einer hydraulischen Bremsflüssigkeit, die den in den Standardbestimmungen SAE 70 R 1 niedergelegten Wassertoleranztest besteht.The aim of the invention is to provide a hydraulic brake fluid that is in the standard provisions SAE 70 R 1 passed water tolerance test.
Die erfindungsgemäße hydraulische Bremsflüssigkeit besteht aus einem Additionsprodukt von Rizinusöl und Alkylenoxyden und einem oder mehreren Alkoholen, Glykolen oder Glykolalkyläthern als flüchtigen Verdünnungsmitteln und ist dadurch gekennzeichnet, daß das flüchtige Verdünnungsmittel nicht mehr als 80 Gewichtsprozent der Gesamtflüssigkeit beträgt und das Additionsprodukt durch Umsetzung von 1 Mol Rizinusöl mit 19 bis 25 Mol Alkylenoxyd erhalten worden ist.The hydraulic brake fluid according to the invention consists of an addition product of castor oil and alkylene oxides and one or more alcohols, glycols or glycol alkyl ethers as volatile Diluents and is characterized in that the volatile diluent does not exceed 80 percent by weight of the total liquid and the addition product by conversion of 1 mol Castor oil with 19 to 25 moles of alkylene oxide has been obtained.
Das flüchtige Verdünnungsmittel besteht z. B. aus einem Mono-, Di-, Tri- oder Tetraalkylenglykol und/oder deren Alkyläthern, wie 2-Methyl-2,4-pentandiol, Diäthylenglykolmonoäthyläther und Triäthylenglykolmonoäthyläther, oder primären und sekundären einwertigen Alkoholen, wie Äthanol, n-Propylalkohol, Isopropylalkohol und Diacetonalkohol.The volatile diluent consists e.g. B. from a mono-, di-, tri- or tetraalkylene glycol and / or their alkyl ethers, such as 2-methyl-2,4-pentanediol, diethylene glycol monoethyl ether and triethylene glycol monoethyl ether, or primary and secondary monohydric alcohols, such as ethanol, n-propyl alcohol, Isopropyl alcohol and diacetone alcohol.

Als Alkylenoxydkompqnente des Additionsproduktes wird vorzugsweise Äthylenoxyd, ein Propylenoxyd und/oder ein Butylenoxyd verwendet.Ethylene oxide, a propylene oxide, is preferably used as the alkylene oxide component of the addition product and / or a butylene oxide is used.
Das Reaktionsprodukt kann hergestellt werden, indem z· B. das Alkylenoxyd in das auf wenigstens 1000C erhitzte Rizinusöl eingeführt wird. Die Zusammensetzung des Reaktionsproduktes wird geregelt, indem die Anteile an Alkylenoxyd und Rizinusöl, die zusammen erhitzt werden, entsprechend geregelt werden.The reaction product can be produced by, for example, is introduced · the alkylene oxide in the heated to at least 100 0 C castor oil. The composition of the reaction product is regulated by regulating the proportions of alkylene oxide and castor oil that are heated together.
Die Reaktion wird zweckmäßigerweise auf bekannte Weise in Gegenwart eines Katalysators durchgeführt.The reaction is conveniently carried out in a known manner in the presence of a catalyst.
Besteht die nichtflüchtige Fraktion der hydraulischen Bremsflüssigkeit aus dem Reaktionsprodukt des Rizinusöls mit einer Mischung niedrigerer Alkylenoxyde, einschließlich Äthylenoxyd,_ so wird das Rizinusöl vorzugsweise zuerst mit Äthylenoxyd und dann mit dem oder den anderen Alkylenoxyden umgesetzt. Die Alkylenoxydgruppen in dem Molekül des Reaktionsproduktes können entweder willkürlich verteilt oder in Blöcken der gleichen Art von Alkylenoxydgruppen angeordnet sein.The non-volatile fraction of the hydraulic brake fluid consists of the reaction product of the Castor oil with a mixture of lower alkylene oxides, including ethylene oxide, is how it becomes Castor oil is preferably reacted first with ethylene oxide and then with the other alkylene oxides. The alkylene oxide groups in the molecule of the reaction product can either be randomly distributed or be arranged in blocks of the same type of alkylene oxide groups.
Ein Autoklav wird mit 1 Molteil Rizinusöl und einem Katalysator beschickt, verschlossen, mit Stick-An autoclave is charged with 1 molar part of castor oil and a catalyst, sealed, with stick
