Abstract
The invention discloses a friction-reducing and anti-wear additive for lubricating oil and its application. A friction-reducing and anti-wear additive for lubricating oil according to the present invention is composed of the compound 2-aminobenzoxazole compound shown in the following formula: wherein, the R group is selected from the group consisting of alkyl, nitro and halogen atoms Any one or more of two; R 2 The groups are all selected from alkyl groups. A lubricating oil comprising the above-mentioned anti-friction and anti-wear additive for lubricating oil. The invention provides a 2-aminobenzoxazole compound as a lubricating oil additive, and a series of synthesized 2-aminobenzoxazole compounds are used as effective friction-reducing and anti-wear additives for lubricating oil in lubricating base oils , 2-aminobenzoxazole compounds are polar heterocyclic substances, and have active element N in the molecular structure that is conducive to friction reduction, which can effectively control and reduce the friction coefficient of the friction pair with this type of lubricating oil as the lubricating medium And the degree of wear, improve the effectiveness and reliability of lubricating oil.
Description
technical field [0001] The invention relates to the technical field of lubricating oil additives, in particular to a friction-reducing and anti-wear additive for lubricating oil and its application. Background technique [0002] Lubricating oil additives are mainly used to ensure the physical and chemical properties of lubricating oil. Through the selection and use of special additives, the lubricating oil can have better anti-friction and anti-wear properties. The development of industry and the progress of society have higher and higher requirements for lubricating oil additives. Excellent performance and environmental protection are the development trend of lubricating oil additives today. Modern life and industrial production are inseparable from automation and mechanization. In mechanical equipment, as long as there are parts that are in contact with each other and produce relative motion, friction will occur on its surface. However, long-term friction will wear out th...
