Abstract

The invention relates to the technical field of lubricating oil. The invention particularly relates to a graphene lubricating oil which is prepared from the following components in parts by weight: 95to 110 parts of a base oil, 1.0 to 3.0 parts of a molybdate compound, 0.8 to 2.0 parts of modified graphene, 0.9 to 3.0 parts of a dispersing agent, 1.5 to 3.0 parts of a composite antioxidant, 0.2 to 0.5 part of a corrosion inhibitor, 0.12 to 0.2 part of a preservative and 0.05 to 0.2 part of an anti-foaming agent. The prepared lubricating oil has excellent extreme pressure wear resistance, highand low temperature lubricating property, oxidation resistance, colloid stability, water resistance, corrosion resistance and the like, can meet the lubricating requirements of industrial robots usedunder different working conditions, and is high in practicability and economic benefit. The lubricating oil is simple in material composition, low in preparation cost, simple in preparation process and stable in product performance, adopts sulfur-free and phosphorus-free anti-wear agents, has the characteristics of no toxicity, no corrosion, environmental friendliness and the like, and has a relatively great application prospect.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a graphene lubricating oil and a preparation method and application thereof. [0002] technical background [0003] At present, industrial robots are being used more and more in many manufacturing industries. The use of robots can reduce labor intensity, ensure the personal safety of employees, improve production efficiency and production quality, and reduce production costs. Due to the wide range of applications of industrial robots, the complex and changeable working environment, and the need to operate under harsh conditions such as high and low temperature, high speed, and heavy loads, and for a long time in continuous operation, higher requirements are placed on the lubricating oil materials used in robot-related components. , the lubricating oil used is required to have good high and low temperature lubricating properties, oxidation stability, no obvious oxidation af...
