Abstract

The invention discloses biodegradable plant-based anti-wear lubricating oil and a preparation method thereof. The biodegradable plant-based anti-wear lubricating oil comprises vegetable oil, a synthetic ester and a vulcanizing aid. According to the biodegradable plant-based anti-wear lubricating oil, the synthetic ester and the vulcanizing aid are added into the raw materials of the lubricating oil, and polar functional groups are added into the molecular structure of the lubricating oil by utilizing the synthetic ester, so that on one hand, the strength of an anti-wear oil film in a metal contact area is improved, and the anti-wear efficiency is improved; the vulcanizing aid and vegetable oil are used for compounding treatment, sulfur bonds of low-sulfur-content vulcanized ester are mainly episulfide bonds, firstly, the episulfide bonds of the vulcanized ester adsorbed on the friction surface are broken in the friction process to generate hydrocarbon free radicals and sulfur free radicals, the sulfur ion free radicals further react with iron to generate iron sulfide, the amount of the iron sulfide converted into ferric sulfate is increased along with the increase of retention timein air and oil temperature, and substances containing the iron sulfide form a reaction film with low shear strength on the metal surface, so that the wear resistance of the lubricating oil is effectively improved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a biodegradable plant-based anti-wear lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Traditional lubrication The vast majority of oil is mineral-based lubricating oil, which has played a great role in the past industrial fields, but mineral oil is difficult to biodegrade, and almost remains in the environment for a long time. The lubricating oil remaining in the environment will inevitably cause serious pollution to the environment. Judging from the development trend, the biodegradable environment-friendly lubricating oil will replace the existing lubricating...
