Description

technical field [0001] The invention belongs to the field of petrochemical industry, and in particular relates to a biodegradable lubricating oil. Background technique [0002] Lubricants are widely used in aviation, automobile, machining, transportation, metallurgy, coal, construction, light industry and other industries. The vast majority of traditional lubricating oils are based on mineral oil, which has played a huge role in reducing friction and wear, saving energy, prolonging mechanical life and meeting the lubrication needs of harsh working conditions. At the same time, it will inevitably enter the environment through various channels such as transportation, leakage, splashing, overflow or improper discharge, seriously polluting soil and water resources, and destroying the ecological environment and ecological balance. [0003] Chinese patent publication number is that CN103773555A discloses a kind of biodegradable lubricating oil, and this method is by base oil; Ant...
