Dosavadní stav technikyBACKGROUND OF THE INVENTION

Hydraulické kapaliny a zvláště brzdové kapaliny pro motorová vozidla jsou předmětem velmi vysokých požadavků s ohledem na jejich chemické a fyzické vlastnosti. V souladu s existujícími standardy a specifikacemi pro brzdové kapaliny z ministerstva dopravy USA (US Department of Transportation) ve federálním standardu pro bezpečnost motorových vozidel FMVSS č. 116 (Federal Motor Vehicle Safety Standard FMVSS-No. 116) a normě SAE J 1704 publikovaným společností automobilových inženýrů (Society of Automotive Engineers), moderní brzdové kapaliny mají na jedné straně mít vysoké teploty varu ve vysoce bezvodém stavu (rovnovážné teploty varu pod zpětným ghladičem „ERBP) a vysoké teploty varu ve vlhkém stavu („vlhké ERBP), ale na druhé straně mají také mít viskozitu, která se v širokém teplotním rozmezí mění pouze mírně.Hydraulic fluids and especially brake fluids for motor vehicles are subject to very high requirements with regard to their chemical and physical properties. In accordance with existing US Department of Transportation standards and specifications for brake fluids in the Federal Motor Vehicle Safety Standard FMVSS No. 116 and SAE J 1704 published by automotive engineers (Society of Automotive Engineers), modern brake fluids are supposed to have high boiling points in the highly anhydrous state (equilibrium reflux temperature "ERBP") and high boiling points in the wet state ("wet ERBP") on the one hand, but They should also have a viscosity that varies only slightly over a wide temperature range.

Kromě toho existují ze, strany automobilového průmyslu přísnější požadavky na zlepšenou ochranu proti korozi v případě kovů a neželežných kovů. Inhibitory koroze v brzdových kapalinách mají za pracovní úkol zabránit destrukci kovových materiálů způsobené korozí.In addition, there are stricter requirements from the automotive industry for improved corrosion protection for metals and non-ferrous metals. Corrosion inhibitors in brake fluids are designed to prevent corrosion of metallic materials.

Použití 1H-1,2,3-triazolů, jako je 1H-1,2,3-benztriazol nebo 1H-1,2,3-tolutriazol, jako inhibitorů koroze v hydraulických kapalinách nebo brzdových kapalinách je po určitou dobu známé, například z EP-A 028 789 (1) aThe use of 1H-1,2,3-triazoles, such as 1H-1,2,3-benztriazole or 1H-1,2,3-tolutriazole, as corrosion inhibitors in hydraulic or brake fluids has been known for some time, e.g. EP-A-028,789 (1) a

EP-A 454 110 (2).EP-A-454,110 (2).

WO 00/46325 (3) doporučuje hydraulické kapaliny, které obsahují kombinaci 1H-1,2,3-benztriazolu nebo jeho derivátů, jako jsou 1H-1,2,3-tolutriazol a 1H-1,2,4-triazol nebo jejich deriváty v poměru hmotnostním od 1 : 4 do 4 : 1, jako inhibitorový systém proti korozi. Pro účely srovnání, tabulky 1 až 4 v publikaci (3) také ukazují hydraulické kapaliny, které obsahují samotný 1H-1,2,4-triazol v koncentracích o 0,15 % hmotnostního, avšak jeho korozi inhibující působení je přijatelné pouze v případě mědi.WO 00/46325 (3) recommends hydraulic fluids containing a combination of 1H-1,2,3-benztriazole or derivatives thereof such as 1H-1,2,3-tolutriazole and 1H-1,2,4-triazole or their derivatives in a weight ratio of from 1: 4 to 4: 1, as a corrosion inhibitor system. For purposes of comparison, Tables 1 to 4 of publication (3) also show hydraulic fluids which contain 1H-1,2,4-triazole alone in concentrations of 0.15% by weight, but its corrosion inhibiting action is acceptable only in the case of copper .

Hydraulické a brzdové kapaliny pro motorová vozidla, které jsou známé z dosavadního stavu techniky, jsou však stále neuspokojivé s ohledem na jejich vlastnosti a zvláště jejich ochranu proti korozi. Je proto předmětem přítomného vynálezu poskytnout hydraulické kapaliny, které zvláště uspokojují výše uvedené požadavky na zlepšenou ochranu proti korozi v případě kovů a neželezných kovů.However, hydraulic and brake fluids for motor vehicles known from the prior art are still unsatisfactory with regard to their properties and in particular their corrosion protection.

Brzdové kapaliny BF la a BF 2a podle tohoto vynálezu se liší od BF 1 a BF 2 pouze v tom, že 0,05 % hmotnostních 1H-1,2,3-tolutriazolu se nahradí stejným množstvím 1H-1,2,4— -triazolu; brzdová kapalina BF lb obsahuje 0,04 % hmotnostního 1H-1,2,4-triazolu a 0,01 % hmotnostního adeninu místo 0,05 % hmotnostního 1H-1,2,3-tolutriazolu; brzdová kapalina BF lc podle tohoto vynálezu obsahuje 0,07 % hmotnostního 1H-1,2,4-triazolu (ale pouze 54,98 % hmotnostních esteru kyseliny borité s triethylenglykolmonomethyletherem) místo 0,05 % hmotnostního 1H-1,2,3-tolutriazolu.The brake fluids BF 1a and BF 2a of the present invention differ from BF 1 and BF 2 only in that 0.05% by weight of 1H-1,2,3-tolutriazole is replaced by the same amount of 1H-1,2,4- triazole; the brake fluid BF 1b contains 0.04 wt% 1H-1,2,4-triazole and 0.01 wt% adenine instead of 0.05 wt% 1H-1,2,3-tolutriazole; the BF 1c brake fluid of the present invention contains 0.07 wt% 1H-1,2,4-triazole (but only 54.98 wt% boric ester with triethylene glycol monomethyl ether) instead of 0.05 wt% 1H-1,2,3- tolutriazole.

Aplikační studie se provádějí podle zkoušky na korozi mědi PSA Peugeot-Citroěn D 53 5387 ve verzi 2000. Při zkoušce se nejprve měděný plech, který se předtím očistí v acetonu, s celkovou plochou povrchu 1000 cm2 (rozměry: 71,4 cm x 7 cm x 0,05 cm) svine do formy kruhového válce takovým způsobem, že povrch kovu ve vnitřku se navzájem nedotýká. Měděný plech se umístí do směsi 294 ml brzdové kapaliny obsahující 6 ml destilované vody a zahřívá se na 100 °C po 100 hodin, přičemž skrz kapalinu prochází 10 litrů za hodinu vzduchu, který se předtím nechal projít destilovanou vodou ochlazenou na 2 °C. Po zkoušce se vizuálně vyhodnocuje vzhled nesvinutého měděného plechu a vzhled kapaliny a stanoví se obsah mědi v kapalině.Application studies are carried out according to the copper corrosion test PSA Peugeot Citroen D 53 5387 version 2000. In the test, the copper sheet, which has been previously cleaned in acetone, is first coated with a total surface area of 1000 cm 2 (dimensions: 71.4 cm x 7) cm x 0.05 cm) is wound into a circular cylinder in such a way that the metal surface in the interior does not touch each other. The copper plate is placed in a mixture of 294 ml of brake fluid containing 6 ml of distilled water and heated to 100 ° C for 100 hours, passing through the fluid at 10 liters per hour of air previously passed through distilled water cooled to 2 ° C. After the test, the appearance of the unwound copper plate and the appearance of the liquid are visually evaluated and the copper content of the liquid is determined.

Výsledky z popsané zkoušky jsou uvedeny v tabulce 1 dále.The results of the described assay are shown in Table 1 below.

Můžeme pozorovat, že formulace podle tohoto vynálezu, v protikladu k běžným brzdovým kapalinám, jako jsou BF 1 a BF • · · · · ·It can be observed that the formulations of the invention, as opposed to conventional brake fluids such as BF 1 and BF

2, nenabízejí pouze velihi dobrou ochranu proti korozi mědi s nízkým obsahem mědi ve zkušební kapalině, ale navíc také vytvářejí povrch kovu bez povlaku a v brzdové kapalině se nevytvářejí žádné sedliny.2, they not only offer a very good corrosion protection of low copper copper in the test fluid, but also provide a metal surface without coating and no sediment is formed in the brake fluid.

Výsledky uvedené dále pro zkoušku koroze podle SAE J 1704 (leden 1997) také potvrzují, že brzdové kapaliny podle tohoto vynálezu, jako je BF 2a, která má nízký obsah 1H-1,2,4-triazolu, nabízejí výhody proti formulacím, které nejsou podle tohoto vynálezu, jako je BF ld, která má vysoký obsah 1H-1,2,4-triazolu, jelikož vykazují lepší výsledky v oblasti koroze v případě mědi (BF ld odpovídá BF 1, ale obsahuje 0,20 % hmotnostního 1H-1,2,4-triazolu místo 1H-1,2,3-tolutriazolu a obsahuje pouze 54,85 % hmotnostních esteru kyseliny borité s triethylenglykolmonomethyletherem).The results presented below for the corrosion test of SAE J 1704 (January 1997) also confirm that the brake fluids of the present invention, such as BF 2a, which has a low 1H-1,2,4-triazole content, offer advantages over formulations that are not according to the invention, such as BF 1d, which has a high content of 1H-1,2,4-triazole, since they show better corrosion results in the case of copper (BF 1d corresponds to BF 1 but contains 0.20 wt% 1H-1 2,4-triazole instead of 1H-1,2,3-tolutriazole and contains only 54.85% by weight of boric ester with triethylene glycol monomethyl ether).

Výsledky ze zkoušky koroze podle SAE J 1704 (leden 1997) jsou uvedeny v tabulce 2 dále.The results from the corrosion test according to SAE J 1704 (January 1997) are shown in Table 2 below.
