Description
Technical Field
The invention relates to a hydraulic fluid composition, in particular to a gas-phase corrosion-resistant water-glycol flame-retardant hydraulic fluid composition and a preparation method thereof.
Background
Hydraulic fluids are the vehicle for power transmission in hydraulic transmission systems and must be flame retardant under special conditions of use (e.g., near high temperatures or open flames) in order to prevent accidents that can occur if the hydraulic fluid leaks from valves, pumps, lines, etc. during use. The water-glycol type fire-retardant hydraulic fluid (HFC type fire-retardant hydraulic fluid) is one of fire-retardant hydraulic fluids, and the water-containing type fire-retardant hydraulic fluid has better lubricating property than high water-based fluid (HFA type fire-retardant hydraulic fluid), better stability than emulsion (HFB type fire-retardant hydraulic fluid), lower price than anhydrous synthetic fluid (HFD type fire-retardant hydraulic fluid) such as phosphate ester and the like, and better fire resistance than mineral oil type hydraulic fluid. However, the rust-proof performance is far inferior to that of non-water-based hydraulic oil, and in the use process, the corrosion of the inside of an oil tank and the upper part of the liquid level of the oil tank, the corrosion of a valve and the corrosion of a hydraulic pump shell are easy to occur, and the normal use of a hydraulic system, the wear resistance and the anti-foaming performance of hydraulic liquid are seriously affected by particles generated after the corrosion.

The preparation method comprises the following steps: (1) heating octanoic acid and diethanol amine in a reaction kettle at 50-80 ℃ according to the weight ratio, uniformly stirring and reacting for 50 minutes; (2) under the conditions of continuous stirring and constant temperature, sequentially adding softened water, glycol, isooctanol, polyether, morpholine, dye and defoaming agent in a certain proportion; (3) and finally, fine filtering by a filter device to obtain a product. The product has the characteristics of flame resistance, wear resistance, good defoaming property and the like.
Patent CN101802154A discloses a water-glycol hydraulic fluid composition, i.e. a substantially morpholine-free water-hydraulic fluid composition, comprising water, a glycol, a polyglycol, an aliphatic carboxylic acid comprising 6 to 14 carbon atoms, and a combination of an amine and an alkanolamine.
Patent CN104073333A discloses a water-glycol fire-resistant hydraulic fluid and a preparation method thereof. The raw materials comprise: 35-50% of deionized water, 5-20% of polyether, 0.2-3% of extreme pressure antiwear agent, 0.1-1% of metal passivator, 0.5-3% of antirust additive, 0.5-3% of anticorrosive bactericide, 0.001-0.1% of anti-foaming additive, 0.5-4% of pH stabilizer and the balance of ethylene glycol and/or diethylene glycol. The percentage is the mass percentage of the raw materials, wherein the polyether is a copolymer of ethylene oxide and propylene oxide. The water-glycol fire-resistant hydraulic fluid prepared by the invention can be suitable for various fields such as mines, metallurgy, steel, military industry, ships and the like, inhibits the propagation and growth of bacteria and fungi, and has good biological stability and long service life. Meanwhile, the flame retardant has good flame resistance, lubricity, defoaming property, low temperature property, antirust property and the like.
Patent CN102086422A relates to a water-glycol fire-resistant hydraulic fluid, which comprises the following components by weight percent: 37-42% of water, the balance of ethylene glycol or diethylene glycol, 12-15% of water-soluble polyether tackifier, 0.1-0.2% of sulfur-containing extreme pressure antiwear agent, 1.0-3.0% of antiwear agent formed by compounding capric acid or capric acid and caprylic acid, 1.5-3.0% of at least one amine type antirust agent, 0.1-0.3% of metal passivator, 0.01-0.02% of disodium ethylene diamine tetraacetate, 0.005-0.02% of benzoic acid and 0.002-0.005% of defoaming agent; the invention is characterized in that: the product has strong high-pressure wear resistance and good lubricating property under the high-pressure working condition, and the Vickers 104C vane pump bench test (ASTM D7043) with the test pressure of 14MPa verifies that the vane pump wear is less than 100 mg.
With the development of modern hydraulic equipment towards high speed, high temperature and large capacity, the demand of water-glycol flame-retardant hydraulic fluid is more and more, but the use of the water-glycol flame-retardant hydraulic fluid is limited to a certain extent by the antirust performance, especially the gas-phase antirust performance.

The liquid phase and gas phase antirust performance of the water-glycol flame-retardant hydraulic liquid product on different metals is improved.

The SH/T0752 rust prevention experiment (corrosion resistance) conditions are as follows: at the temperature of 35 ℃, a surface dish is arranged on a beaker without a mouth, a metal sheet is hung below the beaker, and after the beaker is placed for 672h, the surface condition and the weight loss of the test piece are gradedAt a material density of more than 7kg/dm3The mass loss of the metal test piece is not more than 10 mg; the density of the material is less than 7kg/dm3The mass loss of the metal test piece is not more than 5 mg; for zinc flakes, the mass loss per metal coupon should not exceed 20 mg; for aluminum flakes, the mass loss per metal coupon should not exceed 10 mg.
Compared with an SH/T0752 antirust experiment, the MIL22072(C) antirust experiment condition is more severe, the temperature of oil products in a hydraulic oil tank is closer to the actual use temperature (the oil temperature in a general oil tank is 40-55 ℃), the experiment temperature is 66 ℃, an experiment piece is placed in a sealed experiment bottle, water vapor leakage is avoided, and the part of the experiment piece on the liquid surface is not allowed to be stained with the experiment liquid except the part under the liquid surface. The passing or failing criteria are: after the experiment, if the surface of the experimental piece is positioned on the liquid surface and the lower part of the liquid surface has visible rusty spots or discoloration, and if the surface of the experimental piece has no rusty spots or discoloration, the experiment is passed.
The SH/T0752 rust prevention experiment and other physicochemical standard test results in GB/T21449-; the results of the gas phase rust prevention test of MIL22072(C) of the water-ethylene glycol fire-resistant hydraulic fluids of the respective examples and comparative examples are shown in table 2.
TABLE 1 Water-ethylene glycol fire-resistant Hydraulic fluids GB/T21449-
TABLE 2 results of gas phase rust prevention experiments
As can be seen from tables 1 and 2, the water-ethylene glycol flame-retardant hydraulic fluid obtained in each example can pass gas phase rust prevention experiments of red copper, brass, steel sheets and aluminum sheets, and other physical and chemical indexes meet the national standard GB/T21449-2008. The hydraulic fluid of comparative example 1 has sediment and can not obtain clear hydraulic fluid, while the hydraulic fluid of comparative example 2 can keep clear and transparent under the conditions of high temperature and low temperature and can also pass the test of SH/T0752, but the hydraulic fluid has discoloration and rusty spot generation under the gas phase rust prevention test condition of MIL22072(C) and can not meet the use requirement.
The water-glycol fire-retardant hydraulic fluid has excellent antirust performance, and even has good liquid-phase and gas-phase antirust performance on materials such as aluminum, brass, red copper, steel and the like. Not only can meet the requirement of rust prevention performance in GB/T21449, but also can meet the requirement of gas phase rust prevention performance of MIL22072(C) which has extremely strict requirement on the gas phase rust prevention performance.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
