Problems solved by technology

However, the preparation process of alkyl salicylate is complex and the product cost is high
Calcium sulfonate and alkyl salicylate are compounded to prepare lubricating oil composition. Although the advantages of both are combined, the additives are prone to turbidity or precipitation during the storage and use of the oil, which affects its further use.

Abstract

The invention discloses environment-friendly lubricating oil for an automobile. The environment-friendly lubricating oil for the automobile is prepared from the following raw materials by weight percentage: 0.8-1.3% of high-base-number synthesized calcium sulfonate, 0.2-2.0% of alkylated diphenylamine, 1.0-3% of tricresyl phosphate, 0.5-2.0% of a mixture of ethylene propylene polymer and polymethacrylate, 0.015-1.5% of antirust agent, 1-3% of vinyl acetate, 1-3% of methylsilicone oil, 1-3% of anitimony diisopropyl dithio phosphate, 1-3% of glycol ester monooleate and the balance of base oil. Compared with the prior art, the environment-friendly lubricating oil for the automobile has the benefits that the high-temperature cleanliness, the anti-oxidation stability, the antifriction and abrasive resistance, and the base value retainability are excellent, the average oil consumption is low, the engine noise and the engine vibration are reduced, the automobile runs more stably, and the driving control performance is remarkably improved.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to an automobile environment-friendly lubricating oil. Background technique [0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. [0003] 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. [0004] Mineral base oils are refined from crude oil. The main production processes of lubricating oil base oil are: atmospheric an...
