The invention discloses antifreezing fluid for a hydraulic support and a preparation method of the antifreezing fluid for the hydraulic support. The antifreezing fluid for the hydraulic support is characterized by comprising the following components in percentage by weight: 5.0% to 10.0% of triethanolamine oleate, 4.0% to 8.0% of petroleum sodium sulfonate, 3.0% to 5.0% of Turkey red oil, 1.0 to 2.0% of sodium benzoate, 5.0% to 8.0% of triethanolamine, 0.1% to 0.3% of benzotriazole, 30.0% to 50.0% of ethylene glycol, 2.0% to 3.5% of OP-15 and the balance of water. The sum of the weight percentages of the components is 100%. The antifreezing fluid for the hydraulic support, disclosed by the invention, has the beneficial effects that triethanolamine oleate, petroleum sodium sulfonate and OP-15 are used in a compounded state to greatly enhance the rubber compatibility of the antifreezing fluid for the hydraulic support; besides being used as a lubricant of the antifreezing fluid for the hydraulic support, the Turkey red oil further has strong resistance to hard water; sodium benzoate has a very strong bactericidal capability by being taken as a preservative; benzotriazole has an excellent corrosion inhibiting ability for copper and alloy of the copper.

Antifreezing fluid for hydraulic support and preparation method thereof

The invention discloses a production method of an anti-freezing solution for a hydraulic support, and relates to the technical fields of anti-freezing solution production. The preparation method comprises the following steps: S1, preparing deionized water and ethylene glycol, adding the deionized water, the ethylene glycol and hyposilicate into a container according to a ratio of (30%-50%): (40%-60%): (5%-10%), uniformly stirring and shaking, and standing for 20 minutes at normal temperature to form a primary stock solution; S2, taking out 10 ml of the prepared primary stock solution for detecting the PH and ion concentration of the solution, then taking out a certain amount of the primary stock solution, and adding a preservative, a corrosion inhibitor, an anti-scaling agent, an anti-coagulation agent, an odor-resistant agent and an anti-thickening agent into the taken-out primary stock solution. The ethylene glycol and the deionized water are proportioned according to a proper proportion, so that the proportion of other reagents added into the anti-freezing agent is relatively low, the manufacturing cost of the product can be reduced, the efficient preparation of the product is facilitated, the freezing point can be reduced, and the market competitiveness of the product is improved.

Production method of anti-freezing solution for hydraulic supports

The invention provides a high-performance environmentally-friendly antifreeze solution for hydraulic supports. A preparation method of the antifreeze solution comprises the following steps: stirring and reacting glycerol, castor oil polyoxyethylene ether, boric acid, potassium hydroxide and water at 60 DEG C to generate an extreme pressure lubricant; and mixing ethylene glycol used as a main anticoagulant, sodium nitrite used as an antirust agent, the extreme pressure lubricant, sodium nitrite and water according to a certain ratio, and performing stirring and blending at 35-40 DEG C until thesystem is uniform and transparent in order to obtain the stable-performance antifreeze solution for hydraulic supports. The antifreeze solution has the advantages of low antifreeze point, stable usestate, good lubrication, rust prevention, extreme pressure and compatibility properties, and simplicity in production; the preparation method has the advantages of shortening of the production periodby half, avoiding of long-time high-temperature saponification reaction process in the production process, reduction of the material cost, safety and environmental protection; and insoluble substancesare not mixed into the product, so that the product quality is high.
