Abstract

The invention discloses an improved lubricating oil. The lubricating oil is prepared from the following raw materials in parts by weight: 7-14 parts of hydroxy benzyl aldehyde, 5-10 parts of dodecyl benzene sodium sulfonate, 5-10 parts of methyl ciTCMLIBate, 9-12 parts of dichloromethane, 4-10 parts of citric acid mono-methyl ester, 5-8 parts of potassium dihydrogen phosphate, 6-9 parts of tetrahydropalmatine, 3-5 parts of hydrochloric acid, 16-24 parts of sulfur phosphorus primary-secondary alkyl zinc salt, 9-17 parts of sodium citrate, 10-15 parts of sulfureted isobutene, 8-17 parts of sulfureted alkyl phenol calcium, 10-20 parts of methyl acrylate and 30-50 parts of lubricating base oil. The improved lubricating oil disclosed by the invention has the advantages of a better frictional property, a better abrasion-proof property, a better antirust property and stable nature, and the lubrication quality of the lubricating oil is effectively improved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an improved lubricating oil. Background technique [0002] Lubricating oil additives are one or several compounds added to lubricants to obtain new properties or improve some existing properties of lubricants. Additives are classified by function into antioxidants, antiwear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-rust agents, flow point improvers, viscosity index enhancers types of agents. The additives sold in the market are generally compound products of the above single additives, which are unstable in nature and easily reduce the use effect of lubricating oil. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an improved lubricating oil with good frictio...
