Abstract

The invention relates to an antirust oil composition, and a preparation method and application thereof, and mainly solves the problem of incapability of simultaneously implementing rust prevention and high cleanliness in the prior art. The composition comprises the following components in parts by weight: a) 75-90 parts of base oil, b) 5-15 parts of oil-soluble barium sulfonate rust inhibitor, c) 1-3 parts of synthetic ester, d) 0.5-1 part of extreme-pressure antiwear additive and e) 0.1-1 part of other additives. The technical scheme well solves the problem, and can be used in industrial production of the high-cleanliness antirust oil composition.

Description

technical field [0001] The invention relates to an antirust oil composition, a preparation method and an application thereof. Background technique [0002] Bearings are precision basic parts, which need to go through cleaning, drying and anti-rust packaging before leaving the factory. The cleanliness of its products has a greater impact on its performance and life. Cleanliness is an important quality index for low-noise, high-reliability, and long-life precision bearings. Rust on the bearing will affect its accuracy level, reduce its service life or even be scrapped, and even cause accidents during use. Therefore, anti-rust and vibration reduction of bearings are an important issue that both the production and use units of bearings should pay great attention to. In addition, the good cleanliness of bearing lubrication and antirust oil products can reduce vibration and noise for oiled bearings, and oils with high cleanliness will not block the automatic oiling circulation s...
