0752 antirust of SH/T tests (corrosion resistance) condition are as follows: at 35 DEG C, surface plate, lower close plating are set on no mouth beaker
Piece, after placing 672h, grades according to strip situation and test piece weightlessness, is greater than 7kg/dm for density of material3Metal
Test piece mass loss should be no more than 10mg；7kg/dm is less than for density of material3Metal testing plate mass loss should be no more than
5mg；For zinc metal sheet, the mass loss of each metal testing plate should be no more than 20mg；For aluminium flake, the quality of each metal testing plate is damaged
Mistake should be no more than 10mg.
It is tested compared to 0752 antirust of SH/T, the antirust experiment condition of MIL 22072 (C) is more harsh, also closer to practical
Oil product is temperature (oil temperature is 40 DEG C~55 DEG C in general fuel tank) in hydraulic oil container when use, and experimental temperature is 66 DEG C, experiment slice
It is placed in sealing experiment bottle, vapor is avoided to leak, in addition to part under liquid level, the part on liquid level does not allow to be stained with experiment slice
Test(ing) liquid.Standard whether determining to pass through are as follows: experiment slice surface is located on liquid level after experiment, whether there is or not visible rust for part under liquid level
Point, whether there is or not metachromatism, no rust spot and then testing without metachromatism passes through.
0752 antirust of SH/T of each embodiment water-ethylene glycol nonflame hydraulic fluid test and GB/T 21449-2008 in its
His physical and chemical standards test result is as shown in table 1；The MIL 22072 of the water-ethylene glycol nonflame hydraulic fluid of each embodiment and comparative example
(C) volatile rust prevention experimental result is as shown in table 2.
1 water-ethylene glycol nonflame hydraulic fluid GB/T 21449-2008 of table
2 volatile rust prevention experimental result of table
By Tables 1 and 2 as it can be seen that the obtained water-glycol fire-retardand hydraulic fluid of each embodiment can by red metal, brass,
The volatile rust prevention experiment of steel disc, aluminium flake, other physical and chemical indexes are all satisfied national standard GB/T21449-2008.The hydraulic fluid of comparative example 1
There is precipitating to generate, clarification hydraulic fluid cannot be obtained, although the hydraulic fluid of comparative example 2 can keep clarification under high temperature and cryogenic conditions
It is transparent, also can by the test of SH/T 0752, but its occur under MIL 22072 (C) volatile rust prevention experiment condition discoloration,
Rust staining is generated, requirement cannot be reached.
Water-glycol fire-retardand hydraulic fluid of the invention has excellent rustless property, or even to aluminium, brass, red metal, steel
Etc. materials all have good liquid phase, volatile rust prevention performance.It is not only able to satisfy rustless property requirement in GB/T 21449, can also be expired
Foot requires volatile rust prevention performance the volatile rust prevention performance requirement of extremely harsh MIL 22072 (C).
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
Various corresponding changes and modifications, but these corresponding changes and modifications can be made according to the present invention by knowing those skilled in the art
It all should belong to the protection scope of the claims in the present invention.
