Abstract

The invention provides an anhydrous total-synthesis fire-retardant hydraulic fluid. The anhydrous total-synthesis fire-retardant hydraulic fluid comprises 5-8 parts of paraffin, 20-30 parts of liquid-state rosin, 3-6 parts of anhydrous lanolin, 8-15 parts of coconut diethanolamide, 10-16 parts of triethanolamine, 5-10 parts of benzotriazole, 5-15 parts of dibutyl succinate, 40-60 parts of acetone,10-15 parts of emulsifier, 4-9 parts of cooling agent, 5-10 parts of corrosion inhibitor, 6-12 parts of anti-foaming agent and 3-8 parts of surfactant. The anhydrous total-synthesis fire-retardant hydraulic fluid has the advantages that the hydraulic fluid does not contain water and has high corrosion resistance; manifold combustion test results show that the hydraulic fluid is incombustible, construction safety is increased greatly, and the problem that a traditional hydraulic fluid is poor in lubricating performance and easily abrades and corrodes metal can be solved effectively.

Description

technical field [0001] The invention relates to the field of hydraulic fluid for lubricating transmission media, in particular to an anhydrous fully synthetic flame retardant hydraulic fluid and a synthesis method thereof. Background technique [0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. For hydraulic oil, first of all, it should meet the requirements of the hydraulic device for the viscosity of the liquid at the working temperature and the starting temperature. Since the viscosity change of lubricating oil is directly related to hydraulic action, transmission efficiency and transmission accuracy, it is also required that the viscosity-temperature performance and shear stability of the oil should meet the various requirements of different uses. [0003] In some hydraulic s...
