Lubricant oil and preparation method of same

Abstract

The invention discloses lubricant oil which is composed of, by weight, 100-150 parts of basic oil, 10-20 parts of an anti-wear agent, 5-10 parts of an anti-wear enhancer, and 3-10 parts of an anti-rust agent. Compared with the prior art, the lubricant oil has the following advantages: 1) a mixture composed of ferrocene, 3-(2-thiophene)propionic acid and ethyl 2-chloro-6-fluorophenylacetate, in special ratio, is employed as the anti-wear enhancer, so that the performance of anti-wear agents in the prior art is greatly improved, and the lubricant oil is excellent in anti-abrasion performance; 2)by means of the basic oil in specific weight ratio, namely, a mixture comprising mineral oil of which the ISO-VG viscosity grade is 100, castor oil and poly-alpha-olefin PAO15 according to mass ratioof 10:2:1, the lubricant oil is high in fuel oil saving rate; and 3) the anti-rust agent is a mixture of petroleum sodium sulfonate, triethanolamine borate and amide according to the mass ratio of 5:3:1, so that the lubricant oil has excellent anti-rust performance.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to an anti-wear lubricating oil. Background technique [0002] Lubricating oil is a liquid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil accounts for 85% of all lubricating materials, and there are many types and grades. Now the world's annual consumption is about 38 million tons. 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 categori...

Problems solved by technology

[0005] At present, the commercially available lubricants mainly have the functions of lubrication, rust prevention, cooling, etc. Although the different functions of the lubricating oil have been further improved, due to the unreasonable selection of additives, the performance of the lubricating oil such as anti-wear and friction reduction is still poor, and wear The amount is large, which is the deficiency of the existing technology
