Embodiment 1
[0047] A kind of lubricating oil, is made up of following component by weight:
[0048] 120 parts of base oil
[0049] Anti-wear agent 15 parts
[0050] Anti-wear enhancer 8 parts
[0051] Antirust agent 7 parts.
[0052] Described base oil is the mixture of the mineral oil of ISO VG viscosity grade 100, castor oil and polyalphaolefin PAO15, and its mass proportion is 10: 2: 1;
[0053]The preparation method of described antiwear agent comprises the following steps:
[0054] S1, adding 2 parts by volume of sodium hypochlorite with a mass percentage concentration of 3% to 45 parts by volume of diesel oil to obtain sulfur-free fuel oil;
[0055] S2, remove all water and the sundries formed by sodium hypochlorite;
[0056] S3, blending 30 parts by volume of lead naphthenate with a mass percentage concentration of 24%, 15 parts by volume of sulfur-free fuel oil and 15 parts by volume of light mineral oil to form a blend;
[0057] S4. Slowly and uniformly heat the blend to 15...

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...
