Abstract

The invention provides lubricating oil with graphene. The lubricating oil contains the following components in parts by weight: 190-250 parts of lubricating-oil base oil, 13-16 parts of glyceryl tristearate, 10-15 parts of polymethacrylate, 5-10 parts of polyisobutene, 10-13 parts of octyl phenol, 4-5 parts of fluorine surfacant, 14-18 parts of silane coupling agent, 7-10 parts of diisocyanate and 5-15 parts of oxidized graphene powder. The lubricating oil provided by the invention has the advantages that an additive and the base oil are better in compatibility; by the combined effect of polymethacrylate and polyisobutene, the viscosity index of the lubricating oil is obviously increased; simultaneously due to addition of the graphene, the stability of the lubricating oil is improved; and the anti-freezing and anti-rusting properties and the wearing-resistant and lubricating properties are better.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a graphene lubricating oil. Background technique [0002] As an important petroleum product with high technical content, lubricating oil has a wide range of applications and is used in almost all mechanical fields. The quantity and types of lubricating oil products in our country are constantly increasing, but there is still a big gap in product quality and grade compared with developed countries. Therefore, improving product quality and product grade is an urgent need for my country's lubricating oil industry. [0003] Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and endow some new properties. An important component of oil. [0004] Viscosity index and stability are important indicators of lubricat...
