Abstract

The invention discloses an energy-saving and environment-friendly lubricating oil. The lubricating oil comprises, by weight, 100 to 300 parts of castor oil, 50 to 150 parts of eleostearic acid, 100 to200 parts of sorbitol, 50 to 100 parts of graphite powder, 20 to 40 parts of sodium citrate, 10 to 40 parts of coconut diethanolamide, 30 to 60 parts of a viscosity index improver, 10 to 20 parts ofan antioxidant, 20 to 40 parts of a friction improver, 10 to 30 parts of an anticorrosive agent and 35 to 55 parts of a demulsifying agent. The antioxidant is one of tea polyphenol, tocopherol and flavonoids. The invention also discloses a preparation process of the energy-saving and environment-friendly lubricating oil. The prepared environment-friendly lubricating oil has good lubricating performance, can reduce environmental pollution by saving energy consumption, has small influence, can be biodegraded, and can be absorbed by the environment so as to achieve the purpose of no harm, and thepreparation method is simple, wide in raw material source and low in cost, and has certain environment-friendly and energy-saving significance.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an energy-saving and environment-friendly lubricating oil and a preparation process thereof. Background technique [0002] The naturally renewable and biodegradable properties of vegetable oils allow them to offer significant environmental and economic sustainability benefits over conventional lubricants. In addition to these benefits, vegetable oils also have advantages over traditional mineral base oils, including low volatility, high flash point, high viscosity index, and excellent lubricity. Therefore, bio-based lubricating oils derived from vegetable oils have become the main force of environmentally friendly lubricating oils. However, how to overcome the poor oxidation stability and low-temperature performance of vegetable oils has become a major obstacle. [0003] Environmentally friendly lubricating oil is also called environmentally acceptable lubricating oil. ...
