Abstract
The invention relates to hydraulic fluids, in particular brake fluids for motor vehicles, with improved anti-corrosion properties, containing (a) between 0.005 and 0.125 wt. % 1H-1,2,4-triazole and (b) between 0 and 10 wt. % of one or more corrosion inhibitors, whereby with the co-use of 1H-1,2,3- benzotriazole and/or 1H-1,2,3-tolyltriazole and/or their derivatives, the weight ratio of 1H-1,2,4-triazole to the aforementioned 1H-1,2,3-triazoles must be greater than 4:1.
Claims (5)
1. A brake fluid for motor vehicles having improved corrosion protection, comprising (a) from 0.005 to 0.125% by weight of 1H-1,2,4-triazole, and (b) from 0 to 10% by weight of one or more further corrosion inhibitors, where, on concomitant use of 1H-1,2,3-benzotriazole and/or 1H-1,2,3-tolutriazole and/or derivatives thereof, the weight ratio between 1H-1,2,4-triazole and said 1H-1,2,3-triazoles must be greater than 4:1, and furthermore from 0.1 to 97% by weight of one or more polyglycol ethers and/or boric acid esters thereof.
2. A brake fluid for motor vehicles as claimed in claim 1, comprising from 0.005 to 0.08% by weight of component (a).
3. A brake fluid for motor vehicles as claimed in claim 1 or 2, comprising component (a) as the only triazole-based corrosion inhibitor.
4. A brake fluid for motor vehicles as claimed in claim 1 or 2, comprising, as component (b), from 0.001 to 0.5% by weight of one or more compounds from the group consisting of benzimidazole, hydrogenated 1H-1,2,3-tolutriazole, purine, adenine, 6-chloropurine, 2,6-dichloropurine, 6-methoxypurine, 1H-1,2,3-triazolo(4,5-b)pyridine, 6-histaminopurine and 6-furfurylaminopurine, and, if desired, further corrosion inhibitors other than (a).
5. A brake fluid for motor vehicles as claimed in any of claims 1 to 4, furthermore comprising, besides components (a) and, if desired, (b), from 0.1 to 50% by weight of one or more polyglycols.
