Problems solved by technology

Many of the existing emulsified oils require high-temperature saponification in production, which is not only costly, but also needs to be further optimized in terms of stability, rust resistance and corrosion resistance. Moreover, oil and soap often precipitate during use, causing blockage of filter valves, Problems with easily polluted parts such as bracket valve core, filter and emulsification pump box

Embodiment 1

[0048] According to the mass ratio of ancient oil: oleic acid triethanolamine soap: water=6:1:3, the three are compounded to obtain the emulsifier of the present invention, and the more commonly used naphthenic acid soap is selected as a comparison, and the two are added respectively 9 times the mass of water is made into 10% aqueous solution, and the stability of each aqueous solution is measured. The results are shown in the table below:

[0049] Table 1

[0050] name Aqueous solution stability Sodium naphthenate soap solution Oil analysis 0.3%; soap analysis 0.2% The aqueous solution of the compounded emulsifier of the present invention Oil separation

[0051] As can be seen from the above table, the emulsifier obtained by compounding the three of the present invention is much more stable than the aqueous solution of naphthenic acid soap.

Embodiment 2

[0053] (1) prepare emulsified oil compound, the emulsified oil compound of the present embodiment is made by following raw material by weight:

[0054]

[0055]

[0056] The emulsifier is made of the following three raw materials in a mass ratio of ancient oil: oleic acid triethanolamine soap: water = 6:1:3.

[0057] The preparation method of the emulsified oil compound agent of the present embodiment is through the following steps:

[0058] 1) prepare an emulsifier in the ratio of Swire oil: oleic acid triethanolamine soap: water=6:1:3 by mass ratio;

[0059] 2) Mix and stir the prepared emulsifier, OP-10 and sodium alkylbenzene sulfonate for 20 minutes at room temperature until the solution is clear;

[0060] 3) Add lubricating oil (this embodiment is mechanical oil) and triethanolamine, stir evenly, and stir at room temperature for 20 minutes until the solution is clear;

[0061] 4) Add EDTA, NaOH, and Tween and stir evenly, then add triethanolamine oleic acid soap ...

Embodiment 3

[0074] (1) prepare emulsified oil compound, the emulsified oil compound of the present embodiment is made by following raw material by weight:

[0075]

[0076] The emulsifier is composed of the following three raw materials: Swire oil: oleic acid triethanolamine soap: water=6:1:3 by mass ratio.

[0077] The preparation method of the emulsified oil compound agent of this embodiment is the same as that of Embodiment 2.

[0078] (2) Prepare emulsified oil: add the emulsified oil compound prepared in this example and mechanical oil into the container according to the mass ratio of 1:2, and then stir at room temperature for about 30 minutes until uniform to obtain the oil base Emulsified oil products.

Abstract

The invention provides an emulsified oil compound agent, a preparation method, emulsified oil prepared therefrom and its application. The emulsified oil compound is made of the following raw materials in parts by weight: 10-20 parts of emulsifier, 15-20 parts of lubricating oil, 15-20 parts of sodium alkylbenzene sulfonate, 2-5 parts of polyethylene glycol surfactant 2-5 parts of oleic acid triethanolamine soap, 3-7 parts of triethanolamine, 2-7 parts of EDTA, 1-3 parts of NaOH, 2-6 parts of Tween, 2-6 parts of Span, 4-6 parts of ethylene glycol 10 parts, 2-4 parts of urea, 1-3 parts of sodium nitrite, 0.05-0.2 parts of special copper corrosion inhibitor, 0.05-0.2 parts of defoamer, 7-13 parts of solvent water. Mix the compounding agent with water or oil to obtain emulsified oil. The stability, lubricity, rust resistance and corrosion resistance of the emulsified oil prepared by the compound agent of the invention are all higher than those of the prior art, and the freezing point is also lower, which is very suitable for electro-hydraulic control systems.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to an emulsified oil compounding agent and a preparation method thereof, and emulsified oil prepared therefrom and its application. Background technique [0002] Now the coal group company gradually improves the mining equipment for coal mining according to the coal seam occurrence conditions of each mine, and puts forward higher requirements for the transmission medium of the hydraulic support. The need for coal mine construction is gradually increasing, and energy conservation and cost reduction have also become market needs. Among them, the transmission medium for coal mine hydraulic support is mostly emulsion liquid for hydraulic support, which is generally prepared by adding emulsified oil and water on site. Many of the existing emulsified oils require high-temperature saponification in production, which is not only costly, but also needs to be further optimize...
