Abstract

The invention relates to a concentrated liquid lubricant and a preparation method thereof, which belong to the technical field of hydraulic transmission media. The concentrated liquid lubricant of the invention is prepared from the following raw materials in percentage by weight: 50.0 to 70.0 percent of deionized water, 1.4 to 3.7 percent of KOH, 1.0 to 10.0 percent of triethanolamine, 24.0 to 15.0 percent of NaNO, 3.0 to 10.0 percent of OS-15, 0.2 to 0.8 percent of benzene benzotriazole, 2.0 to 6.0 percent of ethylenediaminetetraacetic acid, 2.0 to 10.0 percent of sodium benzoate, 0.1 to 0.5 percent of emulsified silicone oil, 5.0 to 15.0 percent of triethanolamine oleate, 1.0 to 5.0 percent of polyalkylene glycol, 1.0 to 8.0 percent of polycarboxylic antirust, and 2.0 to 8.0 percent of glycol. The concentrated liquid lubricant of the invention has the advantages of good lubrication, cooling, corrosion resistance and cleaning performance and longer service life.

Description

technical field [0001] The invention relates to a concentrated liquid lubricant and a preparation method thereof, in particular to a lubricant for a coal mine hydraulic support and a preparation method thereof, belonging to the technical field of hydraulic transmission media. Background technique [0002] Hydraulic support is one of the main equipment of mechanized coal mining production. Its support, lifting, moving, pushing and overload protection all need to use the flow of pressure liquid in the hydraulic system to realize energy transmission and conversion. This pressure liquid Commonly known as the transmission medium. [0003] The hydraulic transmission medium is an important part of the hydraulic system. The hydraulic system initially used water as the transmission medium, but water lacks lubricity, low viscosity, and is easy to cause metal corrosion, so it is gradually replaced by petroleum-based mineral oil hydraulic transmission medium. Although petroleum-based ...
