Description
DK 152846B
Opfindelsen angår en blanding til anvendelse som hydraulisk væske, nemlig en hydraulisk væske på mineraloliebasis. 1 hydrauliske systemer, i forbindelse med hvilke mineralolie eller visse andre væsker er specificeret som den operative væske, opstår der problemer på grund af tilstedeværelsen af vand. Dette vand kan være til stede som resultat af kondensation eller utilstrækkelig tørring før fyldningen af systemet eller på et senere tidspunkt ved diffusion gennem slidte pakninger eller flexible slanger. I hvert tilfælde kan væskens damplåstemperatur reduceres til kogepunktet af vand, selv ved tilstedeværelse af meget små mængder vandf f.eks. af størrelsesordenen 0,5 pct. Dette udgør en alvorlig ulempe med særligt farlige konsekvenser i de systemer,
DK 152846 B
2 der omfatter bremsesystemer.
Det er opfindelsens formål at angive en blanding til anvendelse som hydraulisk væske, i forbindelse med hvilken tilstedeværelsen af små mængder vand, som på utilsigtet måde er indført i systemet, ikke vil reducere blandingens damplåstemperatur til en temperatur, der er så lav som vands kogepunkt.
Blandingen ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 angivne. Det har overraskende vist sig, at tilstedeværelsen af små mængder vand, som på utilsigtet måde er indført i blandingen ifølge opfindelsen, ikke vil reducere blandingens damplåstemperatur til en temperatur, der er så lav som vands kogepunkt .
Det kræves, at den boratester, som anvendes i blandingen ifølge opfindelsen, skal være olieopløselig, og i tilfælde af trialkyl-borater kan olieopløseligheden tilvejebringes ved at udvælge en ester fremstillet ud fra ligekædede alkoholer, der indeholder under 12 carbonatomer eller fremstillet ud fra forgrenede· alkoholer, der indeholder op til 24 carbonatomer. I tilfælde af boratestere af den type, der er afledt af di- og polyoxyalkylenglycolethere, er de, der er afledt af di- og polyoxyethylenglycolethere, sædvanligvis uopløselige, medmindre i det mindste en af de terminale ethergrupper er tilstrækkelig til at solubilisere esteren. Som et alternativ kan man opnå olieopløselighed i forbindelse med denne sidste type af ester ved at inkorporere polyoxypropylen- eller højere polyoxyalkylen-radikaler i molekylet.
Eksempler på særligt anvendelse boratestere omfatter: tris-(dipropylenglycolmonomethylether)-borat tri s-(ethylenglyc oImonobutylether)-b orat tris-(triethylenglycolmonobutylether)-borat tris-(tripropylenglycolmonomethylether)-borat tri-n-decyl-borat tri-(isotridecyl)-borat tri-(2-ethylhexyl)-borat 3
DK 152846B
Den amin, der anvendes i forbindelse med den foreliggende opfindelse, bør have et rimeligt lavt damptryk, der er forligeligt med, at der tilvejebringes en damplåstemperatur over 120° 0. Den anvendte amin vil også afhænge af den anvendte boratester. En simpel prøve til bestemmelse af, om en særlig amin er anvendelig til forhindring af udfældning af olie-uopløselige hydrolyseprodukter af en særlig boratester, omfatter, at man opløser aminen og boratet i den udvalgte smørende olie (i de mængder, der er tilstræbt i den sluttelige hydrauliske væske), at man forsegler den resulterende væske sammen med 0,5 vægtprocent vand i en klar glasampul, og at man opvarmer til 100° 0 i 24 timer og afkøler. Hvis den resulterende opløsning er klar og lys i forbindelse med den såkaldte "ampul"-prøve, er kombinationen tilfredsstillende.
Det har vist sig, at mange aminer er velegnede, herunder primære, sekundære og tertiære aminer, især de, der totalt indeholder mindst 5 carbonatomer. Aminer, der har vist sig at være særligt anvendelige i forbindelse med et bredt sortiment af borater, omfatter "Primene 81 R" og "Primene JMT”, der er kommercielt rekvirerbar.e primære aminer med to methylgrupper på alfa-carbonatomer.
Andre aminer, der kan være anvendelige, er Mannich-baser, fremstillet vedikondensation af en amin og formaldehyd med en phenol, der tidligere er alkyleret med di- eller polyisobutylen, poly-isobutenyl-succinimider afledt af di- eller polyaminer, eller amider, afledt af di- eller polyalkyl-polyaminer og polyisobutenyl-substituerede monocarboxylsyrer.
Mængderne af bestanddelene (b), (c) og (d) kan variere inden for vide grænser. Det foretrækkes imidlertid at anvende mellem 1 og 50 pct, især mellem 1 og 20 pct., i særdeleshed mellem 5 og 10 pct. på vægtbasis af boratesteren, mellem 1 og 50 pct., især mellem 5 og 30 pct., i særdeleshed mellem 10 og 20 pct. på vægtbasis af ortoesteren, og mellem 0,5 og 20 pct, især mellem 1 og 10 pct. på vægtbasis af amin, hvorved procentdelene er baseret på den totale vægt af blandingen.
4 DK 152846B
Forholdet mellem ortoester og borat kan for eksempel variere mellem 10:1 og 1:10 på vægtbasis, men i almindelighed vil man anvende mere ortoester end borat, hvorved det foretrukne forhold varierer mellem 5:1 og 2:1 på vægtbasis.
Den smørende olie, der anvendes som basisvæske i blandingerne ifølge opfindelsen, er fortrinsvis en mineralolie, men den kan også være en syntetisk carbonhydridolie, en syntetisk carboxyl-syreester eller blandinger deraf, en siloxan eller en phosphat-ester eller en anden kendt, syntetisk smøreolie.

Yderligere blandinger blev sammensat på basis af et sortiment af forskellige orthoestere og boratestere. I hvert tilfælde anvendte man "Primene JMT" som aminbestanddelen, og basisvæsken var en naphthenisk mineralolie med følgende egenskaber:
Yiskositet : 130 cS ved -40°C, 3,5 cS ved 38°C og
1,31 cS ved 99° C
Hældepunkt : < -57° C
Kogepunkt : 248° C

Flammepunkt (lukket): 208° C
Anilinpunkt : 76° C
Prøver af disse blandinger blev underkastet Gilpin (3 ml) damplåsprøven (i) efter reaktion med 0,5 pct. vand ved 100° C i 24 timer og (ii) efter at være udsat for en fugtighedsprøve ved en relativ fugtighed (RH) på 80 pct. og en temperatur på 22° C, i det væsentlige som beskrevet i FMVSS 113-specifikationen, men udstrakt til en 5 dages periode og uden en referencevæske. Man bestemte også gummikvældningsegenskaberne af forsøgsvæskerne hvad angår nitrilgummi ved at måle volumenforøgelsen af et 2,54 cm kvadratisk, 2 mm tykt nitrilgummiprøvestykke i 50 ml væske ved 120° C i 3 dage.
