Abstract

The invention discloses oxidation-resisting lubricating oil for civil use, which is prepared from the following components in parts by weight: 10 to 30 parts of vegetable oil, 10 to 12 parts of triethanolamine oleate, 5 to 10 parts of alpha-olefin polymer, 10 to 15 parts of polypropylene glycol adipate, 5 to 10 parts of dipropylene glycol dibenzoate, 3 to 6 parts of chlorinated paraffin, 2 to 10 parts of organosiloxane, 3 to 8 parts of boric acid, 3 to 6 parts of anticreaming agent, 5 to 10 parts of triethanolamine, 1.5 to 7.5 parts of organic molybdenum, 3 to 6 parts of alkyl diphenylamine, and 0.3 to 2.5 parts of additive. The invention provides the oxidation-resisting lubricating oil for the civil use and a preparation method thereof, wherein the lubricating oil is excellent in anti-rust property, antioxidant resistance and abrasion resistance, has good foam inhibition and defoaming properties and good chemical inertness, and cannot have chemical reaction with defoamed medium under different pH values and different temperatures.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to an anti-oxidation civil lubricating oil and a preparation method thereof. Background technique [0002] Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in a large amount (about 95%), but in some applications, products formulated with synthetic base oils and bio-oil base oils must be used, thus making these two base oils develop rapidly. [0003] Vegetable oil-based lubricating oil is an environmentally friendly lubricating oil, such as soybean oil, corn oil, rapeseed oil, cottonseed oil, etc., among which the earliest to enter the market is the lubricating oil synthesized from rapeseed oil (oil content 35-40) in Germany . However, rapeseed oil has a high freezing point and is easy to solidify at low temperatures, and its low-temperature performance...
