Embodiment 1

[0058] The content of each raw material component of the biodegradable fully mechanized support electro-hydraulic control concentrate is as follows:

[0059]

[0060] And the remaining water, based on the total mass of each raw material component of the concentrate.

[0061] The preparation method of described concentrated solution is: (1) in the first reactor, add 50kg castor oil, 15Kg potassium hydroxide and 85Kg deionized water, mix and be warming up to 80 ℃, carry out saponification reaction. Stirring reaction 8 hours, obtain potassium ricinoleate soap; (2) add 50kg oleic acid, 25kg triethanolamine and 85kg deionized water in the second reactor, mix and be warming up to 140 ℃, carry out saponification reaction. The reaction was stirred for 6 hours to obtain the triethanolamine oleic acid soap; (3) at a temperature of 50°C, the potassium ricinoleic acid soap obtained in (1) was mixed with the triethanolamine oleic acid soap obtained in (2), and press Add the ether carbo...

Abstract

The invention relates to the technical field of hydraulic fluid, in particular to a biodegradable fully mechanized mining support electrohydraulic control concentrated solution. The concentrated solution is prepared from, by weight, 6-12% of vegetable oil, 1-3% of alkali, 3-15% of oleic acid, 2-7% of triethanolamine, 0.5-1% of a hard water resisting agent, 0.05-0.5% of a corrosion inhibitor, 0.01-0.05% of a defoaming agent and the balance of water based on the total mass of all the raw material components of the concentrated solution. The concentrated solution disclosed by the invention has excellent biodegradability. The invention further provides hydraulic fluid containing the concentrated solution, and the hydraulic fluid is lower in cost and environmentally friendly.

Description

technical field [0001] The disclosure relates to the technical field of hydraulic fluid, in particular to a biodegradable fully mechanized support electro-hydraulic control concentrate and hydraulic fluid containing it. Background technique [0002] With the rapid development of my country's economy, the demand for coal is also increasing, coal enterprises have been developed and expanded, and the degree of mechanization of coal mining industry has also been continuously improved. At the same time, with the occurrence of mine safety production accidents more and more frequently, safety production has become an important issue in today's coal mine production. The popularization of fully mechanized coal mining has improved the safety of coal mine underground production, and it can ensure the safety of the underground working space and function space. [0003] The high-water-containing hydraulic fluid prepared with the concentrated solution for the hydraulic support of fully m...
