Abstract

The invention discloses green and environment-friendly mine hydraulic support liquid which is prepared from mineral base oil and an additive, wherein the additive is prepared from the following ingredients of fatty acid, alkyl amine, diethylene glycol monobutyl ether, an emulsifier, benzotriazole, EDTA tetrasodium, alcohol amine, a water-based antirust agent, sodium hydroxide, a sterilizing agentand a defoaming agent. Preferably, a recommended use concentration is 4 to 5%V/V. The green and environment-friendly mine hydraulic support liquid disclosed by the invention has the advantages of transparent appearance, no odor, no volatile substance, no harmful substance of sodium nitrite, heavy metal and the like, ability in preventing the body of a worker from being damaged, greenness and environmental friendliness; by means of the concentration adjustment, the green and environment-friendly mine hydraulic support liquid can be suitable for different work qualities; furthermore, freeze thawing resistance is excellent, a mine long wall mining requirement can be met, use cost is lower, petroleum resources are saved, and environmental pollution is reduced; the green and environment-friendly mine hydraulic support liquid is a very good emulsified oil replacing product, can be widely applied to coalmine production and has obvious economical benefits and social benefits.

Description

【Technical field】 [0001] The invention relates to the technical field of hydraulic support fluid, in particular to a green and environment-friendly mine hydraulic support fluid. 【Background technique】 [0002] Mine hydraulic support fluid is a fire-resistant hydraulic fluid developed for advanced mine hydraulic supports and other industrial hydraulic systems. At present, most of the mine hydraulic support fluids use sodium nitrite as an anti-rust additive. As an anti-rust additive, sodium nitrite has the characteristics of good anti-rust effect and low cost. However, sodium nitrite has stimulating and carcinogenic effects on the human body, endangering personal health and safety. polluted environment. And the current mine hydraulic support fluid also has the disadvantages of poor resistance to hard water and poor freeze-thaw resistance. Therefore, it is necessary to propose a hydraulic support fluid that is environmentally friendly, has good hard water resistance and stabi...
