Abstract

The invention discloses ultralow temperature ash-free antiwear incombustible ester type hydraulic oil, a production technology and application thereof. The ultralow temperature ash-free antiwear incombustible ester type hydraulic oil is prepared from a viscosity index improver, a pour point reducer, an emulsion breaker, a defoaming agent, an antiwear reagent at extreme pressure, an ash-free detergent dispersant, an antirust agent, an antioxidant, a fire retardant and base oil. The ultralow temperature ash-free antiwear incombustible ester type hydraulic oil has the advantages that firstly, theoil has the extremely stable molecular structure, and the good oxidation stability; secondly, the oil has the extremely good lubricating performance and antiwear performance, and can effectively prolong the life of an engine; thirdly, the oil has the low temperature fluidity so that the engine can be easily started; fourthly, the oil has the good high temperature high shearing performance, the volatile loss at a high temperature is less, and the oil film tenacity and strength of an oil product at the high temperature are ensured; fifthly, the viscocity and the lubrication of the oil can be maintained after a ultralong driving process; sixthly, the oil has the good detergent dispersing performance, and the dust deposition amount is less after the oil is used for a long time; seventhly, theoil has the good biodegradability; and eighthly, the oil has low condensation point and can be widely applied to bad working environments such as low temperature and cold.

Description

technical field [0001] The invention relates to an ultra-low temperature ashless anti-wear and flame retardant ester type hydraulic oil, a production process and application thereof. Background technique [0002] Hydraulic transmission operates working parts by the transmission of liquid pressure energy in a closed container. Because of its small size, light weight, sensitive response, stable transmission, convenient installation and easy operation, it is widely used in steering gear of automobiles and ships, Windlass, navigation system and valve switch remote control system, etc. Hydraulic medium, that is, hydraulic oil, is the medium for transmitting energy in hydraulic transmission, and plays an important role in transmitting energy, lubricating equipment, anti-corrosion, anti-rust and cooling in hydraulic equipment. If the oil pump is the heart of the entire hydraulic system, then the hydraulic medium is the blood of the hydraulic system, which plays a vital role in the...
