[0002] As is known, the synthetic hydraulic support hydraulic fluid is the transmission medium of the coal mine hydraulic support, and plays the role of blood in the hydraulic system. The anti-corrosion performance and anti-rust performance are the key indicators of the synthetic hydraulic support hydraulic fluid, and they can improve various controls of the hydraulic support. The service life of valves and pipelines has a decisive impact. In view of the fact that the water quality used to prepare the hydraulic fluid of the hydraulic support is often salty mine water, the stability of the hydraulic fluid of the support should be good during use, and there must be no oil and soap precipitation, otherwise it will be precipitated. The combination of oil soap and coal dust forms a viscous substance that is difficult to clean, which not only causes a lot of troubles for on-site use, but also blocks the filter components of the electro-hydraulic control system; this requires that the corrosion inhibitor should be resistant to salt water and hard water , should also have good water solubility, and can form a thermodynamically stable system with other additives; at present, there are no reports on this kind of corrosion inhibitor, and it is a technical skill in the art to develop a kind of corrosion inhibitor to meet the actual needs Basic requirements of personnel

Embodiment 1

[0037] Example 1: Add 8% boric acid, 2.3% sebacic acid and 61% triethanolamine into the reaction kettle while stirring and heating for 0.5 hours. The heating temperature is 80°C, and then kept at 70°C until there is no white solid. It turns into brown viscous liquid borate; add 0.6% sodium molybdate and 0.28% benzotriazole to 27.82% distilled water to fully dissolve; after dissolving, add it to the reaction kettle and stir continuously to configure a synthetic hydraulic pressure Corrosion inhibitor for bracket hydraulic fluid.

Embodiment 2

[0038] Example 2: Add 8.5% boric acid, 2.1% sebacic acid and 62% triethanolamine into the reaction kettle while stirring and heating for 1 hour, the heating temperature is 90°C, and then keep it warm at 80°C for a period of time until no white solid until it turns into a brown viscous liquid borate; add 0.7% sodium molybdate and 0.26% benzotriazole to 26.44% distilled water to fully dissolve; after dissolving, add it to the reaction kettle and continue stirring evenly to configure Synthetic hydraulic support hydraulic fluid corrosion inhibitor.

Embodiment 3

[0039] Example 3: Add 9% boric acid, 1.9% sebacic acid and 63% triethanolamine into the reaction kettle while stirring and heating for 0.8 hours, the heating temperature is 85°C, and then keep it at 75°C for a period of time until no white solid until it turns into a brown viscous liquid borate; add 0.8% sodium molybdate and 0.24% benzotriazole to 25.06% distilled water to fully dissolve; after dissolving, add it to the reaction kettle and continue to stir evenly to configure Synthetic hydraulic support hydraulic fluid corrosion inhibitor.

Abstract

The invention relates to a configuration method of a corrosion inhibitor for a hydraulic fluid of a synthetic hydraulic support and relates to the field of water-based corrosion inhibitors. The configuration method comprises the steps of preparing raw materials, preparing boric acid ester, dissolving and obtaining the corrosion inhibitor for the hydraulic fluid of the synthetic hydraulic support. The corrosion inhibitor configured by the configuration method provided by the invention has the advantages of hard water resistance, salt water resistance and good water solubility, a thermodynamically stable system can be formed by adding other additives, and the rust resistance and the corrosion resistance can meet the underground using requirements of a coal mine.
