Problems solved by technology

At present, many coal mining areas use traditional antifreeze for hydraulic supports. This kind of antifreeze is mostly prepared and produced with nitrite as an antirust agent, and this type of antirust agent contains carcinogens. Direct contact with the human body is likely to cause skin cancer, and Some anti-rust agents are easy to remain on the surface of parts to form white spots, and the anti-rust effect is poor
[0003] By searching, no published patent documents related to the present invention have been found

Embodiment 1

[0020] An environment-friendly hydraulic support antifreeze, its composition and weight percentage are respectively (taking 1000g hydraulic support antifreeze as an example):

[0021]

[0022] A preparation method of environment-friendly hydraulic support antifreeze, the steps are as follows:

[0023] ⑴Add appropriate amount of water to reactor A, heat up to 35-50°C, add the reaction amount of dibasic acid to mix, then add the reaction amount of triethanolamine and monoethanolamine and stir, keep the reaction temperature at 40-42°C for 3.5-5 Hour, finally add the benzotriazole of reaction amount and fully stir, form mixed solution a;

[0024] (2) Add the remaining water in step (1) to the reaction kettle B, start stirring at room temperature, then add ethylene glycol, and stir for 10 minutes until the ethylene glycol and water are completely miscible;

[0025] (3) Add polyamide-type emulsifying antirust agent, nonylphenol polyoxyethylene ether, and mixed solution a to reac...

Embodiment 2

[0028] An environment-friendly hydraulic support antifreeze, its composition and weight percentage are respectively (taking 1000g hydraulic support antifreeze as an example):

[0029]

[0030] The steps of its preparation method are the same as in Example 1.

[0031] Mechanism of action of the present invention:

[0032] First, organic acid reacts with triethanolamine and monoethanolamine to form a water-based rust inhibitor. The added boric acid amine rust inhibitor provides a stable pH value and plays a synergistic role in rust prevention with the rust inhibitor body. Boric acid amine The anti-rust agent and sodium benzoate make the hydraulic support antifreeze not corrupt during storage and use and inhibit the growth of bacteria. Adding polyamide emulsified anti-rust agent to the hydraulic support antifreeze can not only prevent rust, but also provide lubrication for the antifreeze. Through the above mechanism of action, the anti-rust and lubricating effects can be opt...

Abstract

The invention relates to an environment-friendly hydraulic support antifreeze fluid and a preparation method thereof. The fluid is composed of the following components in percentage by weight: 0.1 to 0.3% of diacid, 0.5 to 1% of triethanolamine, 0.05 to 0.2% of ethanolamine, 0.1 to 0.3% of benzotriazol, 50 to 54% of glycol, 0.2 to 0.5% of polyamide type emulsion antirust agent, 0.1 to 0.4% of polyoxyethylene nonyl phenyl ether, 0.8 to 1.5% of ammonium borate type antirust agent, 0.8 to 1.5% of sodium benzoate, and the balance being water. The action mechanism of the antifreeze fluid is simple and scientific. Through the synergetic effect between each component, optimum antirust, lubricating and antifreeze effects are abtained. The ammonium borate type antirust agent and the sodium benzoate both have an antiseptic function, and thus can effectively prevent the hydraulic support from corrosion during the storage or work process. The ratio of glycol to water can be adjusted so as to obtain various antifreeze liquids applied in different low temperatures.

Description

technical field [0001] The invention belongs to the field of coal mines, and relates to an antifreeze liquid for a hydraulic support, in particular to an environment-friendly antifreeze liquid for a hydraulic support and a preparation method thereof. Background technique [0002] In winter, in order to ensure that vulnerable parts such as hydraulic support pipelines and gate valves placed in the open air are not damaged by freezing, the hydraulic support emulsion commonly used in the hydraulic support system must be replaced with hydraulic support antifreeze. At present, many coal mining areas use traditional antifreeze for hydraulic supports. This kind of antifreeze is mostly prepared and produced with nitrite as an antirust agent, and this type of antirust agent contains carcinogens. Direct contact with the human body is likely to cause skin cancer, and Some anti-rust agents tend to remain on the surface of parts to form white spots, and the anti-rust effect is poor. [0...
