Abstract

The invention discloses an environmental-friendly hydraulic oil composition and a production method thereof. The environmental-friendly hydraulic oil composition comprises the following raw material components per kilogram: 982 to 986.6 grams of base oil, 11 to 12 grams of antioxidant, 1.0 to 3.0 grams of extrcme pressure antiwear additive, 0.4 to 0.5 gram of metal deactivator and 1.2 to 2.0 gg of antirusting agent. The production method of the environmental-friendly hydraulic oil composition comprises the following steps of: after mixing component oils in the base oil according to a certain ratio, heating to a temperature of 75 to 85 DEG C and stirring for 4 hours; then adding other various additives together; and stirring for 4 hours at a temperature of 50 to 60 DEG C to obtain the the environmental-friendly hydraulic oil composition disclosed by the invention. The environmental-friendly hydraulic oil composition disclosed by the invention has low cost and has performances of excellent abrasion resistance, oxidation resistance, hydrolytic stability, anti-rusting property, biodegradability and the like.

Description

technical field [0001] The invention relates to a hydraulic oil composition, in particular to an environment-friendly hydraulic oil composition and a preparation method thereof, belonging to the technical field of lubricating oil products. Background technique [0002] With the widespread use of lubricating oil, lubricating oil can enter the environment through various channels during use, thereby causing environmental pollution. At present, among the lubricating oils used all over the world, except for a part that is normally consumed by mechanical operation or partially recycled and recycled, 4% to 10% of the lubricating oil still flows into the environment during assembly, disassembly, filling, and mechanical operation. According to statistics, only the European Community has 600,000 tons of lubricating oil lost in the environment every year due to various reasons. [0003] At present, in Europe, especially in Northern Europe, Germany, Switzerland and Austria, environmen...
