Problems solved by technology

[0003] Vegetable oil-based lubricating oil has good sustainable productivity, good lubricating performance, biodegradability, low volatility, and high flash point, and has attracted widespread attention. However, the vegetable oil-based lubricating oil in the prior art has poor oxidation stability. It is easy to form sludge and sediment at high temperature, and it is easy to solidify at low temperature, and the low temperature performance is not ideal. These defects limit the further development of vegetable oil-based lubricants

Abstract

The invention discloses biodegradable environmentally-friendly lubricating oil. The lubricating oil is characterized by comprising the following raw materials in parts by weight: 50-60 parts of modified vegetable oil, 1-3 parts of an antioxidant, 1-3 parts of a viscosity modifier, and 1-3 parts of a rust inhibitor; the modified vegetable oil is prepared by performing hydrosilylation on methyl hydrogen silicone oil and vegetable oil and performing interesterification on the methyl hydrogen silicone oil modified vegetable oil and a phosphate ester compound; and the rust inhibitor is obtained byperforming an esterification reaction on polylactic acid and dodecenylsuccinic acid. The biodegradable environmentally-friendly lubricating oil disclosed by the invention has better viscosity-temperature performance, a more remarkable lubricating effect and more excellent oxidation stability than those of lubricating oil disclosed in the prior art, is biodegradable, and causes less pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a biodegradable environment-friendly lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. A large amount of lubricating oil in the process of production, use and discharge due to infiltration, leakage, spillage and improper handling has caused serious environmental problems that pollute soil and water resources, destroying the ecological environment and ecological balance. Increasing awareness and more and more attention. The development of biodegradable environment-friendly lubricating oil is an effective way to solve this problem and is the future development direction o...
