Problems solved by technology

However, because the product waste liquid is directly discharged underground, EDTA is not easy to degrade underground in coal mines, so it will pollute the environment
Moreover, the amount of EDTA additive in the formula is limited, and the concentration is only allowed to be 4-5%. Based on the nature and amount limit of EDTA reagent, the application of transmission medium in extreme conditions such as extremely high hard water is limited.

Abstract

The invention provides a green and efficient concentrated solution for a hydraulic support system and a preparation method of the green and efficient concentrated solution. The concentrated solution is prepared from components in percentage by mass as follows: 5%-8% of soybean oil, 3%-5% of coconut oil, 4%-6% of potassium hydroxide, 2%-3% of trans-polyether, 7%-10% of polyglutamic acid, 10%-12% ofsebacic acid, 1%-2% of fatty alcohol polyoxyethylene ether, 6%-10% of triethanolamine, 2%-4% of monoethanolamine, 10% of glycol, 0.1%-0.3% of methylbenzotriazole, 1%-2% of trimethyl hexahydrotriazine, 0.1%-0.3% aqueous polyether, 0.01%-0.02% of Congo red and the balance of reagent process water. The concentrated solution is obtained through multiple steps as follows: carboxylic acid amide is prepared from the soybean oil, the coconut oil, triethanolamine and monoethanolamine through a saponification reaction, and methylbenzotriazole, the sebacic acid and carboxylic acid amide are compounded with a metal sustained release agent.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a green high-efficiency concentrated liquid used in hydraulic support systems and a preparation method of the green high-efficiency concentrated liquid used in hydraulic support systems. Background technique [0002] The transmission medium is the "blood" of the hydraulic support system. Actions such as support, lifting, movement, pushing and overload protection of the hydraulic support require the use of transmission medium to realize energy transmission and conversion. The transmission medium of the hydraulic support is divided into emulsified emulsified oil, microemulsion and fully synthetic concentrate. With the rapid development of mining science and technology and the continuous improvement of hydraulic systems, higher requirements are put forward for the performance of transmission media used in hydraulic supports. [0003] In the formulation of the transmission medium ...
