Abstract

The invention relates to a method of preparing biodegradable lubricating oil. The method of preparing biodegradable lubricating oil belongs to the technical field of lubricating oil and comprises the steps: uniformly mixing polyhydric alcohols, vegetable oil, catalysts and organic solvent, heating to perform reaction and obtaining polyol ester; decompressing and distilling the obtained polyol ester, evaporate the organic solvent, adding formic acid, heating and dripping 20-40 parts of hydrogen peroxide; after the dripping is finished, keeping warm, standing and delaminating, removing a water layer, distilling an oil layer, collecting fractions to obtain modified polyol ester; and uniformly mixing the modified polyol ester with base oil, glyceryl triacetate, an xanthan gum, an antirust agent, an anti-wear reagent at extreme pressure and a surfactant to obtain the biodegradable lubricating oil. The lubricating oil provided by the invention keeps better biodegradability and has good anti-wearing property.

[0002] The invention relates to a preparation method of biodegradable lubricating oil, which belongs to the technical field of lubricating oil.

[0003] Background technique

[0004] Bio-lubricating oil is an ultra-clean lubricating oil that protects the environment from air pollution and also has the ability to reduce CO 2 Emissions reduce the characteristics of the greenhouse effect; the development of bio-lubricating oil is conducive to increasing production and improving the diesel / gasoline ratio of my country's oil structure. Hydraulic transmission technology is a transmission technology that is widely used in industry, but most of the current hydraulic systems The use of mineral hydraulic oil as the working medium not only consumes a large amount of oil resources, but also causes environmental pollution. Under this background, countries all over the world are researching environmental protection and energy-saving hydraulic transmission techno...
