Problems solved by technology

However, this invention uses a small amount of sulfurized castor oil as an additive, and the anti-oxidation stability is limited. The base oil is the skeleton of the lubricating oil and plays a decisive role in the performance of the lubricating oil. Therefore, this invention can only limit the improvement of the anti-oxidation performance of the lubricating oil. High temperature wear resistance

Abstract

The invention relates to environment-friendly lubricating oil and a preparation method thereof. The environment-friendly lubricating oil is prepared from the following components in parts by weight: 74.2 to 90.2 parts of slightly vulcanized vegetable oil, 1.3 to 5.6 parts of an antioxidant, 0.5 to 2.8 parts of a friction improver, 2.1 to 4.3 parts of an antioxidant preservative, 2.4 to 5.3 parts of an extreme-pressure anti-wear agent, 0.3 to 1.8 parts of a defoaming agent, 2.0 to 3.8 parts of a metal deactivator and 1.2 to 2.2 parts of an antirust agent. Compared with the prior art, the lubricating oil has the advantages of excellent thermal stability and oxidation stability, good wear resistance, obvious antifriction performance, passivation resistance, good rust resistance, corrosion resistance, environmental friendliness and easiness in biodegradation.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an environment-friendly lubricating oil and a preparation method thereof. Background technique [0002] With the development of precision machinery and automation, people's requirements for mechanical tools are getting higher and higher. Lubricating oil is a liquid or semi-solid used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Lubricants mainly play the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. With the improvement of people's awareness of environmental protection, the requirements for the environmental friendliness of mechanical tools are higher, and practical and environmentally friendly lubricants can help protect the environment. At present, lubricating oils are complicated, some are not resistant to thermal stability and oxidation stability, so...
