Hydraulic fluids comprising nitrogen-containing boric acid esters |
摘要 |
Hydraulic fluids the primary properties of which comply with the official specifications and, moreover, which have a good lubricating effect, a high oxidation stability and a high acid stability consist of about 10 to 60% by weight of a nitrogen-containing boric acid ester, about 5 to 30% by weight of an alkyl-polyethylene glycol tert. butyl ether and about 35 to 75% by weight of a glycol monoalkyl ether. The nitrogen-containing boric acid ester is a reaction product of an alkoxylated monoalkyl amine, orthoboric acid and optionally a glycol.
