Abstract

The invention relates to a lubricating oil technology, in particular to environment-friendly lubricating oil and a preparation method thereof. The invention provides environment-friendly lubricating oil. The environment-friendly lubricating oil is prepared by adding the following substances in percentage by weight relative to neopentyl polyol ester into the neopentyl polyol ester: 0.24-0.96% of nitrogen-containing boric acid ester, 0.24-0.42% of dialkyl pentasulfide, 0.10-0.30% of phosphorus star, 0.1-0.3% of sulfurized isobutylene and 0.09-0.63% of benzotriazole fatty amine salt. The lubricating oil has high bearing capacity and good lubricating and anti-attrition performance.

Description

[0001] This application is a divisional application with an application date of June 24, 2016, an application number of 201610471729.6, and an invention title of "Environmentally Friendly Lubricating Oil Added with Nitrogen-Containing Borate Ester and Other Additives to Neopentyl Polyol Ester". technical field [0002] The invention relates to lubricating oil technology, in particular to an environment-friendly lubricating oil and a preparation method thereof. Background technique [0003] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is generally composed of base oil and functional additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow ...
