Description
Technical Field
The invention relates to the technical field of hydraulic transmission media, in particular to a concentrated solution and a preparation method and application thereof.
Background
The hydraulic support is a structure for controlling the mine pressure of the coal face, has the main functions of supporting a stope top plate, maintaining a safe operation space, pushing working face mining and transporting equipment and the like, and has great influence on economic and technical indexes such as productivity, safety and the like of the fully mechanized coal face in terms of working performance. The hydraulic support fluid is used as a working medium of the hydraulic support, plays a role in power transmission, and plays roles in lubrication, cooling, corrosion prevention and rust prevention, and is called as 'blood' of the hydraulic support. At present, domestic coal mine hydraulic support liquid is generally prepared by blending base oil and a plurality of functional additives, and the lubricating property, the stability, the rust resistance, the corrosion resistance, the compatibility with sealing materials and the like of the domestic coal mine hydraulic support liquid need to be met, so that the domestic coal mine hydraulic support liquid can be used in underground coal mines.
The existing concentrated solution for the hydraulic support has two main technical problems, namely 1, poor stability. Due to the action of hard water and pressure, soluble potassium and sodium soaps are often changed into sticky substances which are not easy to dissolve in liquid or separated out soaps, so that valves and filter screens are blocked. 2. Conflict with environmental protection requirements. Phosphate ester or petroleum lubricants are not environment-friendly, raw materials such as rosin and petroleum acid can emit peculiar smell in the saponification process, and waste liquid can cause water pollution in underground treatment.
Therefore, it is necessary to develop a new concentrate.

The concentrated solution according to the embodiment of the first aspect of the invention comprises the following components in percentage by mass:
the metal lubricating corrosion inhibitor comprises organic dibasic acid; the organic dibasic acid is organic dibasic acid with a carbon chain length of more than or equal to 18.
The traditional transmission fluid for the hydraulic support is an emulsified type, consists of mineral oil, an emulsifier, an oil-soluble antirust additive (such as alkyl sulfonate and the like), a preservative, fatty amine, inorganic base, a complexing agent and the like, has poor hard water resistance, is hard in water quality and easy to break emulsion and separate layers particularly in a mine hydraulic support system, and precipitated soap, the emulsifier, oil and the like are adhered to a pipe wall and a filter screen to influence normal operation. Or the concentrated solution is prepared by chelating organic dibasic acid or inorganic acid such as sebacic acid, boric acid and the like with alcohol amine to form an antirust agent, and adopting phosphate lubricant and other functional additives, although the concentrated solution has better antirust property and lubricity, the concentrated solution has poor hard water resistance and large smell, and influences the environment of an operation space, and meanwhile, because the lubricating property of the organic dibasic acid is poor, the lubricating property of the concentrated solution needs to be improved by adding a lubricating agent at the same time, and the phosphorus-containing lubricating agent is not environment-friendly.
The concentrated solution provided by the embodiment of the invention has at least the following beneficial effects:
the long-carbon-chain multi-polarity strong-adsorption type dibasic acid with the carbon chain length of more than eighteen carbons is adopted, so that the long-carbon-chain dibasic acid has excellent antirust property, has good lubricating property due to the long carbon chain, and omits a phosphate or petroleum lubricant. Is more friendly to the operating space of workers and the environment.
The concentrated solution has the characteristics of good lubricity, stability, filterability, rust prevention, corrosion prevention, sealing material compatibility and the like, does not separate oil and soap, and does not use mineral oil and phosphorus-containing lubricant in the formula. Compared with the traditional emulsified oil, the emulsified oil has better stability.
According to some embodiments of the invention, the metal lubrication corrosion inhibitor further comprises at least one of an organic triacid, triethanolamine, benzotriazole, or methylbenzotriazole.
The long carbon chain dibasic acid is compounded with other antirust additives such as organic tribasic acid, the synergistic principle of various additives is fully utilized, the best composite antirust lubricating corrosion inhibition effect is obtained with a lower dosage, the quality is stable, the environment is friendly, and the lubricating corrosion inhibition effect is better.
According to some embodiments of the invention, the organic diacid is at least one selected from 21 carbon organic diacids.
According to some embodiments of the invention, the 21-carbon organic diacid is cyclopropyloleic acid.
According to some embodiments of the invention, the organic triacid comprises 2,4,6-tris (aminocaproyl) -1,3,5-triazine.
The function of the organic tribasic acid in the application is to increase the instant rust prevention capability in the concentrated solution.
According to some embodiments of the invention, the surfactant is at least one of a fatty acid ether, a fatty alcohol polyoxyethylene ether. Therefore, the concentrated solution has better penetration, emulsification and dissolution assisting effects.
According to some embodiments of the invention, the organic alcohol amine comprises at least one of monoethanolamine, triethanolamine, monoisopropanolamine, or diisopropanolamine. Therefore, the added organic alcohol amine enables the concentrated solution to have better pH value stabilizing effect.
According to some embodiments of the invention, the water quality stabilizer is at least one of sodium gluconate or sodium citrate. Thus, the water quality stabilizer functions to complex heavy metal ions such as calcium ions and magnesium ions in water.
