Description
Technical Field
The invention belongs to the field of transmission media for hydraulic supports of coal mines, and particularly relates to a hard water resistant and low COD concentrated solution for a hydraulic support and a preparation method thereof.
Background
The concentrated solution for the hydraulic support is a substance which can be dissolved in water to form solution type diluent, and generally consists of water, water-soluble antirust agent, anticorrosive agent, lubricant and other additives. The hydraulic support is matched with mine water with the mass ratio of more than 95% to form high-water-content hydraulic fluid as a transmission medium of the hydraulic support to realize the actions of lifting, lowering, pushing, sliding, moving and the like of the hydraulic support. At present, concentrated solution for hydraulic supports usually contains organic carboxylic acid soap (such as oleic acid soap), and the additive is easy to react with calcium and magnesium ions in mine water to generate hard soap which is insoluble in water and separate out, so that a hydraulic system is blocked, and the hydraulic supports cannot normally operate.
In order to prevent precipitation of organic carboxylic acid soap and mine water-insoluble calcium magnesium soap, a certain amount of complexing agent such as EDTA (ethylene diamine tetraacetic acid) is usually compounded in the concentrated solution according to the hardness of mine water so as to avoid precipitation of calcium magnesium soap of organic carboxylic acid. However, the mine water hardness often has larger fluctuation, when the mine water hardness is increased and exceeds the complexing capacity of the high-water-content hydraulic fluid of the hydraulic support, the high-water-content hydraulic fluid is caused to be soapy, floccules and sediments are generated, a hydraulic system is blocked, the hydraulic support cannot normally operate, and the hydraulic support is blocked by the high-water-content hydraulic fluid at present.
Chemical Oxygen Demand (COD) is an important environmental protection index for monitoring mine sewage discharge, and is a comprehensive index for measuring the concentration of reducing pollutants in sewage. The lower the COD value, the lower the content of pollutants in the water. The COD value of the concentrated solution of the hydraulic support is usually very high and above 16000mg/L, so that the reduction of the COD value of the concentrated solution of the hydraulic support is an important requirement for meeting the environmental protection requirement and protecting the underground water quality of a mining area.

As can be seen from Table 1, the respective test results of the sample stock solutions obtained in examples 1 to 3 and comparative examples 1 to 3 all meet the standard requirements.

The evaluation results of the high water hydraulic fluids of the samples of examples 1 to 3 and comparative examples 1 to 3 are shown in tables 2, 3, 4 and 5, respectively, according to the hardness level of artificial hard water.

Table 3 evaluation results of examples and comparative examples of high aqueous hydraulic fluid samples (Artificial hard Water hardness grade 20)
As can be seen from Table 3, each of the test results of the high water content hydraulic fluid samples of examples 1 to 3, comparative example 2 and comparative example 3 satisfies the standard requirement by using the artificial hard water formulation with hardness grade of 20, but the high water content hydraulic fluid sample of comparative example 1 exhibits soap precipitation phenomenon, and the rust resistance and corrosion resistance do not satisfy the requirements.

As is clear from Table 4, each test result of the high water content hydraulic fluid samples of examples 1 to 3 and comparative example 3 satisfies the standard requirement by using the artificial hard water formulation with hardness grade of 30, but the high water content hydraulic fluid samples of comparative example 1 and comparative example 2 exhibit soap precipitation phenomenon, and the rust resistance and corrosion resistance do not satisfy the requirements.

As can be seen from Table 5, with the artificial hard water formulation of hardness grade 40, each test result of the high water content hydraulic fluid samples of examples 1 to 3 satisfies the standard requirements, but the high water content hydraulic fluid samples of comparative examples 1 to 3 all exhibit soap precipitation, and the rust resistance and corrosion resistance do not satisfy the requirements.
As is clear from the above tables 2 to 5, the concentrated liquid samples obtained in examples 1 to 3 of the present invention all have good hard water resistance, do not cause soap separation phenomenon with the increase of the hardness level of the liquid formulation water, and have excellent rust resistance and corrosion resistance. While the complexing agent is adopted to shield calcium and magnesium ions in hard water in the sample of the comparative example, soap is separated out in the sample of the comparative example when the hardness level of the liquid preparation water exceeds the complexing capability of the complexing agent; meanwhile, the rust prevention and corrosion prevention capabilities and the lubricating capability of the comparative sample are obviously reduced due to precipitation of soap.
The samples of examples 1 to 3 and comparative examples 1 to 3 of the present invention were respectively prepared with high water content hydraulic fluid at a mass concentration of 5% using artificial hard water having a hardness of 10, and COD of the high water content hydraulic fluid was detected according to HJ 828-2017 "Potassium dichromate method for determination of Water quality chemical oxygen demand", the detection results of which are shown in Table 6. As can be seen from Table 6, the COD values of the high water content hydraulic fluid samples of examples 1 to 3 of the present invention were significantly lower than those of the high water content hydraulic fluid samples of comparative examples 1 to 3. The main reason is that the multifunctional surfactant is introduced into the raw materials of the concentrated solution for the hydraulic support in the embodiments 1-3, so that the content of other additives (such as rust-proof preservative, bacteriostat and defoamer) can be reduced, and the COD value of the concentrated solution sample in the embodiments 1-3 is also reduced; the raw material cost is also reduced, so that the production cost is reduced, the preparation process of the concentrated solution is simpler, the used equipment is simple, the reaction condition is mild, the energy consumption is lower, and the industrialized mass production is easy to realize.
