Abstract

A provided biodegradable hydraulic oil composition is composed of the following compositions in percent by weight: 0.1-5% of a phenol type or amine anti-oxidant type anti-oxidant , 0.1-5% of a P type or S-P type nonmetal extreme-pressure anti-wear reagent, 0.01-1% of an ashless clean dispersant, 0.01-1% of an ester or calcium sulfonate antirust agent, 0.01-1% of an organic metal passivator, and the balance ester base oil. The beneficial effects comprise that compared with common hydraulic oil, the product possesses protrude biodegradable characteristic (with biodegradation rate greater than 80%, OECD301B) and excellent oxidation stability (with the time longer than 6500 h when the acid value is 2.0 mg KOH / g, ASTMD943(dry)).

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a hydraulic oil composition with outstanding biodegradability and excellent oxidation stability. Background technique [0002] At present, among the lubricants used all over the world, except for a part that is normally consumed by mechanical operation or partially recycled and reused, 4% to 10% of the lubricant still flows into the environment during assembly, disassembly, filling, and mechanical operation. Each year there are about 6×10 5 t lubricants are lost to the environment for various reasons. Traditional lubricant products based on mineral oil have poor biodegradability and long residence time in the natural environment. Once they penetrate into the soil and aquifer, they will cause serious damage to the environment. With the continuous enhancement of human environmental protection awareness, lubricants, especially hydraulic oil, which occupies an important proportion o...
