Problems solved by technology

[0003] However, the existing emulsified oil has poor freeze-thaw properties, anti-wear and extreme pressure resistance, and anti-rust and anti-corrosion properties, which cannot meet the conditions of the hydraulic support in the harsh environment of the underground. Dirty phenomena, such as the precipitation of oil, soap and other dirt, not only make it difficult to keep the equipment system clean and clean, but also increase the number of disassembly and assembly of filters and valves in the system, which affects the normal operation of the system; during use It will cause slow movement of the hydraulic support, which affects the efficiency and safety of the operation

Abstract

The invention provides an emulsified oil for a mining hydraulic support. The emulsified oil is composed of the following substances in percentage by weight: 15.0%-20.0% of mineral base oil, 8.0%-10.0% of boric acid, 10.0%-12.0% of triethanolamine, 10.0%-11.0% of petroleum sodium sulfonate, 0.5%-0.8% of benzotriazole, 20.5%-22.5% of ethylene glycol, 13.5%-15.5% of urea, 6.0%-8.0% of EDTA (Ethylene Diamine Tetraacetic Acid)-tetra sodium, 1.0%-1.5% of sodium hydroxide and the balance of water. The emulsified oil has excellent freeze-thaw property, wear resistance, extreme pressure resistance, and rust and corrosion resistance, and thus is capable of satisfying the use of the hydraulic support under the conditions of an underground severe environment.

Description

technical field [0001] The invention relates to an emulsified oil, in particular to an emulsified oil for mine hydraulic supports, and belongs to the technical field of lubricating compositions. Background technique [0002] The hydraulic support is a mechanical equipment installed in the coal mining face. It is one of the key equipment in the fully mechanized mining face. It consists of columns, oil cylinders, top beams, bases, various control valves and pipelines. Its support, Lifting, moving, pushing and overload protection all rely on the emulsion to flow in a system composed of pipelines and control elements of a certain structure to achieve energy transmission and conversion, so the emulsion prepared with emulsified oil is called hydraulic support The "blood" of the system, there is no doubt that the quality of the emulsified oil is the key to the normal operation of the equipment. [0003] However, the existing emulsified oil has poor freeze-thaw properties, anti-wea...
