Abstract
The present invention discloses zinc-free high pressure anti-wear hydraulic oil. The oil comprises the following components, by mass, 98-99% of base oil, 0.1-1.0% of an antioxidant, 0.2-1.0% of an extreme pressure anti-wear agent, 0.01-0.1% of a rust inhibitor, 0.01-0.1% of a metal passivating agent, 0.01-0.1% of a lustration dispersant and 0.0001-0.001% of an antifoaming agent. The present invention further discloses a preparation method for the zinc-free high pressure anti-wear hydraulic oil. The quality of the hydraulic oil of the present invention meets specification requirements of the anti-wear hydraulic oil superior product in the national standard GB1118.1-94, and can meet specification requirements of the anti-wear hydraulic oil with the highest level Dension HF-0 on the world.
Description
technical field [0001] The invention relates to a hydraulic oil and a preparation method thereof, in particular to a zinc-free high-pressure anti-wear hydraulic oil and a preparation method thereof. Background technique [0002] At present, there are two commonly used high-pressure anti-wear hydraulic oils, that is, the zinc-type formula with stable zinc dialkyldithiophosphate (ZDDP) as the main agent and the ashless formula with sulfur, phosphorus, and nitrogen agents as the main agent. , the performance of these two oils is balanced, showing excellent stability in high-performance vane pump and plunger pump systems, in line with Denison HF-0 and Vickers M-2950-S specifications, DIN51524 (II) specifications and Cincinnati Milascron specifications . [0003] Additives are usually added for high-pressure anti-wear hydraulic oil to have better anti-wear, anti-oxidation, anti-emulsification and anti-rust properties. Since the 1970s, the additive companies in the world have gr...
