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 anti-wear lubricating oil for automobiles, which is composed of the following raw materials in percentage by weight: 2%-3% of alkyl salicylic acid; 0.2%-2.0% of zinc dialkyl dithiophosphate, and 0.6% of borate %‑5%; polyvinyl n-butyl ether 1.0%‑2.5%; benzotriazole 0.05%‑0.40%; alkylnaphthalene 0.1%‑1.0%; methyl silicone oil 1%‑3%; 1%-3% antimony dithiophosphate; 1%-3% butyl stearate; the balance of base oil. Compared with the prior art, the beneficial effects of the present invention are: excellent high-temperature detergency, anti-oxidation stability, anti-friction and anti-wear properties and base number retention, low average fuel consumption, reduced engine noise, reduced engine vibration, The operation is more stable, and the driving and handling performance has been significantly improved.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to an anti-wear lubricating oil for automobiles. 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 and vacu...
