Abstract

The invention provides an emulsified oil for mine hydraulic support, which is composed of the following substances according to the mass percentage: 15.0%-20.0% of mineral base oil, 8.0%-10.0% of boric acid, 10.0%-12.0% of triethanolamine, and 10.0% of sodium petroleum sulfonate %~11.0%, benzotriazole 0.5%~0.8%, ethylene glycol 20.5%~22.5%, urea 13.5%~15.5%, EDTA-tetrasodium 6.0%~8.0%, sodium hydroxide 1.0%~1.5% , The balance is water. The emulsified oil has good freeze-thaw properties, anti-wear, anti-extreme pressure, anti-rust and anti-corrosion properties, and can meet the conditions of the hydraulic support in the harsh environment of the underground.

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...
