Lubricating oil

Abstract

The invention relates to lubricating oil. The lubricating oil is prepared from the following components in parts by weight: 320-400 parts of lubricating oil base oil, 6-9 parts of octylphenol, 3-5 parts of calcium alkyl salicylate, 2-3 parts of a fluorinated surfactant, 2-4 parts of cinnamyl alcohol, 8-10 parts of N, N-dimethylformamide, 8-12 parts of Gemini quaternary ammonium salt and 6-9 parts of diisocyanate. According to the lubricating oil disclosed by the invention, by virtue of compounding action of adding a lubricating oil additive in the lubricating oil and various promoters, the performance of the additive can be optimized, good effect of strengthening the performance of the lubricating oil can be achieved by using a small amount of the additive, the antifreezing performance, the viscosity, the rust prevention performance and abrasion resistance of the lubricating oil can be improved, and the quality of the lubricating oil is greatly improved.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a lubricating oil. Background technique [0002] Lubricating oil is generally the product of fractionated petroleum, and it is also extracted from animal and vegetable oils, including "lubricating grease". Generally, it is a non-volatile oily lubricant. It is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. In order to improve the quality of lubricating oil, it is often necessary to add additives to the lubricating oil base oil to improve various properties of the lubricating oil. The additives sold in the market are generally the composite products of the above single additives. The difference is the single additive. The ingredients are different and the ratio of several single additives in the compo...
