Biodegradable lubricating oil, and preparation method thereof

Abstract

The invention discloses a biodegradable lubricating oil, and a preparation method thereof. The preparation method comprises following steps: 1, raw materials are prepared, wherein the raw materials comprise cotton seed oil, bis(2-ethylhexyl) sebacate, a dispersant, an extreme pressure antiwear agent, an antioxidant, potassium sorbate, dodecenyl succinic acid, a viscosity index improver, an a defoaming agent; 2, an obtained cotton seed oil mixture is introduced into a blending vessel for stirring, and is discharged through a 2-10<mu>m filter so as to obtain a finished product. The biodegradablelubricating oil is scientific and reasonable in formula, is friendly to the environment, is nontoxic, is prepared taking cotton seed oil as a base oil, is cheap, and is biodegradable; cotton seed oilis subjected to functional treatment, so that the lubricating performance and anti-wearing performance of the lubricating oil are improved greatly; the preparation method is simple and convenient, and is convenient for industrialized production. The biodegradable lubricating oil is excellent in wear resistance, lubricating performance, low temperature performance, high temperature performance, and heat oxidation stability, and the bio-degradability and the economical performance are better than those of fully synthetic oil.

Description

technical field

[0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a biodegradable lubricating oil and a preparation method thereof. Background technique

[0002] Lubricating oil plays an indispensable and key role in the operation of equipment, such as anti-wear, anti-friction, cooling and improving efficiency, but usually has poor compatibility with the environment. The biodegradability of traditional mineral lubricating oil is poor, and if leakage occurs during production, storage, transportation and use, it will pollute the environment. Due to the poor biodegradability of mineral lubricating oils, coupled with the enhancement of people's awareness of environmental protection and strict national environmental protection regulations, the research and development of biodegradable lubricating oils has attracted more and more attention. The most popular lubricating oil products in the Chinese market are mostly petroleum-based...
