Biodegradable lubricating oil

Abstract

The invention relates to a biodegradable lubricating oil. The biodegradable lubricating oil is composed of base oil, an antioxidant, a corrosion inhibitor, an antifoaming agent, a metal deactivator, a demulsifier, an anti-wear agent and copper oxide powder, wherein the base oil is composed of synthetic base oil poly(alpha-olefin), synthetic base oil synthetic fat and synthetic base oil polyether; the antioxidant is anyone or a mixture of diarylamine and sterically hindered phenol, wherein the weight ratio of diarylamine to sterically hindered phenol in the mixture is 1:1; the corrosion inhibitor is a salt formed through using fatty acid and amine; the antifoaming agent is polydimethylsiloxane; the metal deactivator is a toluyltriazole derivative; the demulsifier is polyalkoxyphenol; the anti-wear agent is sulfurated triphenyl phosphate; and the copper oxide powder is nanometer powder, and the particle granularity of the powder is 25-35nm. The biodegradable lubricating oil has the advantages of simple preparation method, scientific and environmentally-friendly preparation scheme, degradability, high work temperature range, good lubricating characteristic, long service life, good protection to parts, high comprehensive performances, reasonable cost, realization of above 90% biodegradation of waste oil, extremely low gas discharge, and obvious energy saving effect.

Description

Technical field [0001] The invention relates to a biodegradable lubricating oil, in particular to a preparation scheme and a preparation method of the biodegradable lubricating oil. Background technique [0002] With the continuous development of human civilization, the continuous development of science and technology, and the environmental requirements of human beings for living space, countries all over the world are working hard to maintain environmental quality and air quality. All of them are working hard in the direction of energy saving and emission reduction. Because the main base oil of the original lubricating oil is made of mineral oil as the raw material, all kinds of substances and gases emitted during the preparation and use process are seriously harmful human health. The used waste oil cannot be degraded. As time goes by, the waste oil will increase, which seriously endangers the living space of human beings. The original lubricating oil cannot meet the design req...

AI Technical Summary

Problems solved by technology

The waste oil after use cannot be degraded. As time goes by, there will be more waste oil, which seriously endangers the living space of human beings. The original lubricating oil cannot meet the design requirements of the equipment due to the continuous improvement and update of the equipment. The oil change interval is short, the carbon emission is high, and the price is high, and the use effect is not ideal
