Problems solved by technology

Friction and wear of the seals under dynamic stress can easily lead to mechanical damage to the seals. At the same time, poor hydraulic media can cause swelling and shrinkage of the seal material, which directly leads to leakage of hydraulic media, increased power consumption, and other adverse consequences.
[0003] Fire-resistant hydraulic fluid generally uses water-ethylene glycol as the base oil, and is composed of additives such as water-soluble extreme-pressure anti-wear agent and anti-rust agent, while water-soluble extreme-

Abstract

The invention provides a fire-resistant hydraulic fluid composition, which is characterized by being prepared from a raw material comprising 5 to 8 percent by mass of phosphate rare earth compound. The prepared fire-resistant hydraulic fluid composition can obviously improve frictional wear resistance and rust protection of hydraulic fluid; meanwhile, both swelling and shrinkage of the prepared fire-resistant hydraulic fluid composition for sealing materials, such as chemigum, accord with related standard requirements.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a fire-resistant hydraulic fluid composition, a preparation method thereof, and a hydraulic fluid prepared from the composition. Background technique [0002] The hydraulic system is the most common power conversion, transmission, and control motion system, and water-glycol, mineral oil, synthetic oil, etc. are generally used as hydraulic media. Under dynamic stress, the seals produce friction and wear, which can easily lead to mechanical damage to the seals. At the same time, poor hydraulic media can cause swelling and shrinkage of the seal material, which directly leads to leakage of hydraulic media, increased power consumption, and other adverse consequences. [0003] Fire-resistant hydraulic fluid generally uses water-ethylene glycol as the base oil, and is composed of additives such as water-soluble extreme-pressure anti-wear agent and anti-rust agent, while ...
