Abstract

The invention relates to the technical field of lubricating oil, and concretely relates to a graphene lubricating oil for a robot. The graphene lubricating oil includes 90 to 100 parts of base oil, 2-3 parts of nanometer zinc oxide, 1.0 to 1.5 parts of nanometer silicon dioxide, 0.05 to 0.1 part of graphene, 1.5 to 2.0 parts of stearic acid, 1 to 2 parts of oleic acid, 0.5 to 1.0 part of polyvinylpyrrolidone, 1.2 to 3.0 parts of a composite dispersing agent, 1.5 to 3.0 parts of a composite antioxidant, 0.3 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 product is used in the robot and can achieve the functions of saving oil, resisting abrasion, reducing noise and the like, the efficiency of a speed reducer is improved, and practicability and economic benefits are high. Meanwhile, the prepared lubricating oil material does not contain sulfur, phosphorus and other elements harmful to the environment, is non-toxic, non-corrosive, environment-friendly, simple in preparation process and stable in product performance, and has a great application prospect.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a graphene lubricating oil for robots 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 o...
