Problems solved by technology

Because most of the original properties of lubricating oil are easy to change, causing lubricating oil to deteriorate. Therefore, in order to improve the properties of lubricating oil, additives are needed to improve the properties of lubricating oil. Lubricating oil additives are used to improve some existing characteristics of lubricants. In the market The general performance of the additives is relatively simple, and it is necessary to add a variety of additives to improve the performance of the lubricating oil
Therefore, the existing lubricating oil additives need to be further improved

Abstract

A lubricant additive is prepared from the following raw materials in parts by weight: 6-13 parts of N,N'-bis(1-methylpropyl)-1,4-phenylenediamine, 4-9 parts of sodium dodecyl benzene sulfonate, 7-8 parts of dibutyl phosphite, 4-6 parts of sulfurized isobutylene, 3-6 parts of sodium dodecyl benzene sulfonate, 7-9 parts of petroleum sulfonate, 4.2-5.6 parts of dibenzyl disulphide, 1.5-3.2 parts of dodecylbenzene, 4-6 parts of isooctyl phosphate ester, 1.3-3.6 parts of methyl silicone oil, 3-6.4 parts of sulfurized calcium alkyl phenolate, 1.4-3.5 parts of calcium petroleum sulfonate, 7-9 parts of amphi-di-iso-octyldiphenylamine and 6-12 parts of polyvinyl alcohol. The lubricant additive has the benefits that the viscosity index is greatly improved, the lubrication effect of the lubricant can be improved, and good abrasion resistance and oxidative resistance are achieved.

Description

technical field [0001] The invention relates to a lubricating oil additive. Background technique [0002] Lubricating oil is a liquid lubricant used on various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the role of reducing friction, cooling, sealing, buffering, rust prevention, cleaning and neutralization. Because most of the original properties of lubricating oil are easy to change, causing lubricating oil to deteriorate. Therefore, in order to improve the properties of lubricating oil, additives are needed to improve the properties of lubricating oil. Lubricating oil additives are used to improve some existing characteristics of lubricants. In the market The general performance of the additives of lubricating oil is relatively single, and it is necessary to add a variety of additives to improve the performance of lubricating oil. Therefore, the existing lubricating oil additives need to be further improved. Contents...
