Abstract

The invention discloses a fire-resistant hydraulic oil which comprises the following raw materials in parts by mass: 2-5 parts of sulfosodium aliphatate, 3-6 parts of triethanolamine, 0.1-0.6 part of benzotriazole, 1-4 parts of fatty alcohol polyethenoxy ether, 2-4 parts of monoethoxy alcohol ester sulfosuccinate, 2-3 parts of glycerin monostearate, 1-3 parts of sodium tripolyphosphate, 1-2 parts of silicon dioxide and 6-9 parts of deionized water. The fire-resistant hydraulic oil disclosed by the invention has the advantages of favorable lubricating property, high viscosity index, high use safety, long service life, favorable anticoagulation property, favorable low-temperature fluidity and favorable gas-phase and liquid-phase rust resistance, and can be widely used in hydraulic systems of various fire-prone apparatuses near heat sources for iron making, steel making, compression casting, continuous casting, hot rolling, coal mine, glass product processing and excavation.

Description

technical field [0001] The invention belongs to the field of hydraulic fluid, in particular to a fire-resistant hydraulic oil. Background technique [0002] Hydraulic transmission is based on the transmission of liquid pressure energy in a closed container to operate the working parts. Because of its small size, light weight, sensitive response, stable transmission, convenient installation and easy operation, it is widely used in steering gear and windlass of ships. , navigation system and valve switch remote control system, etc. The hydraulic medium is the medium for transferring energy in hydraulic transmission, and plays an important role in transferring 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 reliability and life of the hydraulic system. A large number of facts sh...
