Abstract

The invention discloses environmentally-allowable type bio-based lubricating oil. The environmentally-allowable type bio-based lubricating oil comprises the following materials in parts by weight: 100 parts of bio-based composite base oil, 10-20 parts of wear-resistant synthetic ester, 1-3 parts of a pour point depressant, 3-6 parts of an extreme-pressure antiwear additive, 0.1-0.5 part of heptadecenoic imidazolidine, 5-8 parts of chlorinated paraffin, 2-5 parts of bornyl acetate, 0.1-0.3 part of alkanolamide, 0.1-0.3 part of dialkyl diphenylamine, 1-3 parts of gas-phase titanium dioxide and 1-4 parts of single polyisobutylene butanediphthalimide; and the bio-based lubricating oil is refined soybean oil, pentaerythritol ester and hydrogenated castor oil with the mass ratio of (5-7):(2-4):1. The environmentally-allowable type bio-based lubricating oil disclosed by the invention has the advantages that the addition of mineral-based base oil is avoided, the influence of the lubricating oil on the environment is avoided to a greatest extent, the obtained lubricating oil is good in comprehensive lubricating performance, has higher economic value and social value, and simultaneously is suitable for industrial production and use.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an environmentally acceptable bio-based lubricating oil and a preparation method thereof. Background technique [0002] As people's awareness of environmental crisis is increasing, it is generally recognized that the environmental pollution caused by a large amount of lubricating oil in the process of production, use and discharge due to penetration, leakage, spillage and improper handling is becoming more and more serious. From the perspective of social development According to the trend, environmentally acceptable lubricating oil and its additives will gradually replace the existing lubricating oil. [0003] Environmentally acceptable lubricating oil refers to lubricating oil that can be decomposed into water and carbon dioxide by active microorganisms in a short period of time. It has the following characteristics: it has good lubricating performance and can reduce env...
