Problems solved by technology

[0002] At present, automotive lubricating oils generally use mineral-based oils or mineral-based synthetic oils as base oils. Once these lubricating oils are discarded, they cannot be degraded after entering the soil for a long time, which will cause serious pollution to the environment for a long time.
Now, technicians in this field are also starting to develop lubricating oils based on plant-based oils, but the attempt to directly add vegetable oil or a

Abstract

The present invention discloses one kind of caster oil-base engine lubricating oil and its preparation process. The caster oil-base engine lubricating oil consists of dibasic acid ester 30-50 weight portions, synthetic ester 15-30 weight portions, safflower oil 2-5 weight portions, perilla seed oil 2-5 weight portions and fatty acid ester 2-5 weight portions, as well as viscosity index improver and functional compounding agent. The preparation process includes mixing the components through stirring at 30-300 deg.c and normal pressure, filtering and packing. The caster oil-base engine lubricating oil has high lubricating efficiency, saving in energy, no pollution, low cost and wide application.

Description

technical field [0001] The invention relates to an engine oil and a preparation method thereof, in particular to a castor oil-based engine lubricating oil and a preparation method thereof. Background technique [0002] At present, automotive lubricating oils generally use mineral-based oils or mineral-based synthetic oils as base oils. Once these lubricating oils are discarded, they cannot be degraded in the soil for a long time, and will cause serious pollution to the environment for a long time. Now, technicians in this field are also starting to develop lubricating oils based on plant-based oils, but the attempt to directly add vegetable oil or animal oil to the formula makes the oil performance not outstanding, and the quality level of the oil itself cannot reach high Model; at the same time, the oil product is easy to age under high temperature conditions, and the service life is short; the oil product is difficult to lubricate and start the engine at low temperature, s...
