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 antioxidant lubricating oil for an automobile. The antioxidant lubricating oil for the automobile comprises the following raw materials by weight percentage: 1-5% of dialkenyl succinimide, 0.2-2.0% of alkylated diphenylamine, 1-3% of lead naphthenate, 0.5-2.0% of polymethacrylate, 3-15% of petroleum barium borate, 1-3% of poly alpha olefin, 1-3% of methylsilicone oil, 1-3% of anitimony diisopropyl dithio phosphate, 1-3% of glyceryl monooleate and the balance of base oil. Compared with the prior art, the antioxidant lubricating oil for the automobile has the advantages 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 engine vibration are reduced, the automobile runs more stably, and the driving control performance is remarkably improved.

Description

Technical field [0001] The invention involves a lubricant, especially for a car antioxidant lubricant. Background technique [0002] Lubricating oil is generally composed of two parts: basic oil and additive.Basic oil is the main ingredient of lubricating oil. It determines the basic nature of lubricating oil. The additives can make up for and improve the lack of basic oil performance. It is an important part of lubricating oil. [0003] Lubricating oil basic oil is mainly divided into three categories: mineral basic oil, synthetic basic oil, and biological basic oil.Mineral base oil is widely used, and the amount is very large (about 95%), but some applications must use products with synthetic basic oil and biological oil basic oil, so these two basic oils develop rapidly. [0004] Mineral base oil is refined from crude oil.The main production process of lubricating oil basic oils include: constant pressure distillation, solvent dehydration, solvent refinement, solvents dehydrat...
