Abstract

The invention discloses a long-life type water-glycol fire-resistant hydraulic fluid. The long-life type water-glycol fire-resistant hydraulic fluid is characterized by comprising the following main materials by mass: 30-40 parts of water, 35-45 parts of glycol, 10-20 parts of tackifier, 3-10 parts of lubricant, 0.6-1.8 parts of composite corrosion inhibitor, 0.05-0.2 part of chelating agent, 0.002-0.005 part of anti-foaming agent, and 0.001-0.002 part of coloring agent; the lubricant is fatty acid amine salt, and the composite corrosion inhibitor is a mixture of mercaptobenzothiazole, sodiummolybdate and methylbenzotriazole. The long-life type water-glycol fire-resistant hydraulic fluid is excellent in stability, has a good lubricating property and a long service life, comprehensively balances the various performances of the fire-resistant hydraulic fluid, meets the actual use requirement of hydraulic equipment, and is particularly suitable for the use requirement of the hydraulic equipment under the high temperature and open fire accessible working environment.

Description

technical field [0001] The invention relates to a long-life water-ethylene glycol fire-resistant hydraulic fluid, which is mainly used in the transmission of pressure in hydraulic systems in industries such as metallurgy, mining, power plants, and machining, which are close to high-temperature open flames. Background technique [0002] Hydraulic oil is the medium for transmitting power in the hydraulic system, and at the same time has the functions of lubrication and cooling. With the development of modern hydraulic equipment in the direction of high speed, high temperature and large capacity, the hydraulic medium may leak from pipelines, pumps and valves during use. also increased. Therefore, the hydraulic oil used in hydraulic equipment close to high temperature and open flame should be flame retardant, so as to avoid fire accidents, causing personal injury and property loss. Water-glycol fire-resistant hydraulic fluid (HFC) is cheaper than phosphate ester anhydrous synth...
