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 an automobile anti-wear lubricating oil, comprising the following raw materials in percentage by weight: 2%-3% of alkyl salicylic acid, 0.2%-2.0% of zinc dialkyl dithiophosphate, 0.6%-5% of borate, 1.0%-2.5% of polyvinyl-N-butylether, 0.05%-0.40% of benzotriazole, 0.1%-1.0% of alkyl naphthalene, 1%-3% of methyl silicone oil, 1%-3% of anitimony diisopropyl dithio phosphate, 1%-3% of butyl stearate and the balance of base oil. Compared with the prior art, the automobile anti-wear lubricating oil has the beneficial effects of excellent high temperature detergency, antioxidation stability, anti-friction and anti-wear properties and base number retentivity, and low average fuel consumption; the noise of an engine is lowered; the vibration of the engine is reduced; the operation is relatively stable; and the driving control performance is obviously improved.

Description

Technical field [0001] The invention involves a kind of lubricant, especially for a car anti -wear lubricating oil. 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, solv...
