Only use a small amount of 1H-1 in hydraulic fluid of the present invention or the motor vehicle brake liquid, 2, the 4-triazole, this economical and ecological aspect be quite favourable.
Following examples are used for setting forth without limitation the present invention.
Application Example
Based on (ERBP:267 ℃ of commercially available DOT 4 or DOT 5.1 braking fluid BF 1, wet ERBP:173 ℃, 676 cSt) and (ERBP:263 ℃ of BF 2-40 ℃ kinetic viscosity:, wet ERBP:181 ℃,-40 ℃ kinetic viscosity: 850cSt) have 0.05 weight %1H-1 respectively, 2, the 3-tolytriazole detects BF 1a of the present invention, BF 1b, BF 1c and BF 2a and compares as the non-ferrous metal inhibiter.
The motor vehicle brake liquid that uses is composed as follows: BF1:
55.00 the triglycol methyl ether boric acid ester of weight %,
43.44 the mixture of the triglycol monomethyl ether of weight %, Tetraglycol 99 monomethyl ether, triglycol monobutyl ether and diethylene glycol monomethyl ether,
1.51 1 of weight %, the mixture of 1 '-imino-diacetic propan-2-ol, thiodiphenylamine and phosphoric acid ester, the 1H-1 of 0.05 weight %, 2,3-tolytriazole BF2:

3.11 1 of weight %, the mixture of 1 '-imino-diacetic propan-2-ol, thiodiphenylamine and phosphonate derivative, the 1H-1 of 0.05 weight %, 2,3-tolytriazole.
The difference part of braking fluid BF 1a of the present invention and BF 2a and BF 1 and BF 2 only is 0.05 weight %1H-1,2, and the 3-tolytriazole is by the 1H-1 of same amount, and 2, the 4-triazole replaces; Braking fluid BF 1b contains 0.04 weight %1H-1, and 2,4-triazole and 0.01 weight % VITAMIN B4, rather than 0.05 weight %1H-1,2,3-tolytriazole; Braking fluid BF 1c of the present invention contains 0.07 weight %1H-1, and 2,4-triazole (but 54.98 weight % triglycol monomethyl ether boric acid esters are only arranged), rather than 0.05 weight %1H-1,2,3-tolytriazole.
Applied research is carried out according to 2000 editions PSA Peugeot-Citro ё n D 53 5387 copper corrosions experiments.In this experiment, at first will in acetone, clean in advance, total surface area is 1000cm 2(copper sheet of size: 71.4cm * 7cm * 0.05cm) is rolled into cylindric, and like this, inner metallic surface just can not contact with himself.Then copper sheet is placed the mixture that contains 294ml braking fluid and 6ml distilled water, and be heated to 100 ℃ 100 hours; The air that passes through from be cooled to 2 ℃ distilled water is in advance passed through fluid with 10 liters/hour speed.After the experiment, visually rank unfolded copper sheet outward appearance and fluid outward appearance, and the copper content in the mensuration fluid.
It is 1 described that experimental result sees the following form.
Table 1:
Cu content [mg/kg] Cu sheet outward appearance The fluid outward appearance pH
BF 1 (contrast): ????24 Thick coating Muddiness, precipitation ??7.4
????BF?1a： ????29 Light, no coating Amber, clarification ??7.6

????BF?1c： ????18 Light, no coating Amber, clarification ??7.5
BF 2 (contrast): ????10 Thick coating Muddiness, precipitation ??7.6
????BF?2a： ????30 Light, no coating Amber, clarification ??7.7
From with the contrast of conventional brake liquid as can be seen, prescription of the present invention is such as BF 1 and BF 2, not only to provide extraordinary copper antiseptic property than low content of Cu in the Experimental Flowing Object, but also obtained not containing the metallic surface of coating, and in braking fluid, form precipitation.
Following result according to SAE J 1704 (in January, 97) corrosion experiment also proves, 1H-1,2, the braking fluid of the present invention that 4-triazole content is lower, such as BF 2a, be better than non-1H-1 of the present invention, 2, the prescription that 4-triazole content is higher, such as BF 1d, (BF 1d is corresponding to BF 1, but contains 0.20 weight %1H-1 because braking fluid of the present invention demonstrates better Corrosion results under the situation of copper, 2,4-triazole, rather than 1H-1,2, the 3-tolytriazole, and only contain 54.85 weight % triglycol monomethyl ether boric acid esters):
Following table 2 has shown the corrosion experiment result who carries out according to SAE J 1704 (in January, 97).
