Abstract

The invention provides a concentrated solution for a hydraulic support for mines and a preparation method, and belongs to the field of oil for the hydraulic support. The concentrated solution comprises the raw materials in parts by weight as follows: 12-18 parts of an antirust agent, 22-27 parts of a composite lubricating agent, 6-10 parts of EDTA (ethylene diamine tetraacetic acid) disodium, 6-8 parts of urea, 5-7 parts of POEA-15, 0.5-1 part of a silicone emulsion and 40-50 parts of water. The preparation method comprises the steps that:1), 6-9 parts of tribasic acid, 1-1.2 parts of hydroxy acid, 1.8-2 parts of boric acid, 11-12 parts of triethanolamine, 1 part of water and 0.3-0.5 part of benzotriazole are utilized to prepare the antirust agent; 2), 5-9 parts of boric acid, 3-6 parts of water, 3-8 parts of monoethanolamine and 12-15 parts of castor oil soda soap are used to prepare the composite lubricating agent; and 3), the raw materials are mixed to prepare the concentrated solution. According to the concentrated solution for the hydraulic support for mines and the preparation method, the condensation point of the concentrated solution is low and is about subzero 30 DEG C, and the concentrated solution is used in the hydraulic system and has the characteristics of sensitive starting at a low temperature, stable operation at a high temperature, small volatility, excellent stability, anti-rust property, cleanliness and lubricity, good protection effect on the hydraulic support sealing system, energy conservation and environmental protection. Therefore, the concentrated solution and the preparation method are particularly suitable for being used in mines.

Description

technical field [0001] The invention relates to an oil liquid for hydraulic supports, in particular to a concentrated liquid for mine hydraulic supports used in coal mines and mines and a preparation method thereof. Background technique [0002] At present, the oil used for hydraulic supports in coal mines and mines has incomplete formulas, is not environmentally friendly, seriously pollutes groundwater, and has mixed usage, which poses hidden dangers to mines, machinery and people. All kinds of underground mining in our country need an advanced and excellent formula, and there is a big improvement in the overall level. Contents of the invention [0003] The technical task of the present invention is to provide a safe, high-efficiency, green and environment-friendly concentrate for mine hydraulic supports and a preparation method for the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [...
