Problems solved by technology

However, the existing lubricating oils are generally effective in reducing friction and wear of lubricating oils, reducing mechanical vibration noise and lowering oil temperature, and have poor oxidation resistance, thereby reducing the service life of lubricating oils; secondly, high-quality lubricating oils on the market The price of lubricating oil is relatively expensive, and most of them have a single effect, and the use effect is not ideal. The oil change cycle cannot meet the basic requirements of mechanical parts such as engines. It is easy to lose the lubrication effect, which will cause wear on the working surface, the machine parts cannot work normally, and accidents may occur in severe cases

Abstract

The invention discloses multifunctional lubricating oil. The multifunctional lubricating oil is prepared from components in parts by mass as follows: 10-20 parts of adamantane phosphate salt, 5-7 parts of a phosphate-methyl methacrylate copolymer, 60-70 parts of base oil, 1-3 parts of a dispersant and 1-3 parts of a clearing agent. A preparation method of the adamantane phosphate salt comprises the steps of preparation of adamantane quaternary ammonium salt and ionic exchange; a preparation method of the phosphate-methyl methacrylate copolymer comprises the steps as follows: methyl methacrylate, triallyl phosphate and polyoxypropylene polyethylene glyceryl ether are mixed, and the mixture is placed in a radiation field in a nitrogen atmosphere to be radiated with a cobalt 60-gamma radiation method for 40-50 min. The multifunctional lubricating oil has excellent extrusion performance and lubricating performance, wide use ranges and multiple functions.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a multifunctional lubricating oil containing adamantyl phosphate ionic liquid. Background technique [0002] Mechanical parts will produce friction and wear during operation, which will cause a large loss of materials and energy, and at the same time cause environmental pollution. Lubricating oil is widely used because it can effectively slow down the friction and wear of mechanical parts and reduce energy loss. The performance of lubricating oil directly affects the working state and service life of mechanical parts. [0003] Lubricating oil is a liquid or semi-solid lubricating oil 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, cooling, rust prevention, cleaning, sealing and buffering. It is the blood of modern industry and defense industry. However,...
