Abstract

The invention relates to a lubricating oil technology, in particular to environment-friendly heavy-load lubricating oil and a preparation method thereof. The formula of the environment-friendly heavy-load lubricating oil is as follows: the following substances in percentage by weight based on neopentyl polyol ester are added into the neopentyl polyol ester: 0.72% of octadecyloxy sulfo nano calcium borate, 0.24% of dialkyl pentasulfide, 0.30% of phosphorus star, 0.30% of sulfurized isobutylene and 0.63% of benzotriazole fatty amine salt. The environment-friendly heavy-load lubricating oil disclosed by the invention has relatively high bearing capacity and relatively good lubricating and anti-attrition performance.

Description

[0001] This application is a divisional case with an application date of June 24, 2016, an application number of 201610467113.1, and an invention title of "Environmentally friendly heavy-duty lubricating oil with octadecyloxythio nano calcium borate added to neopentyl polyol ester" Application. technical field [0002] The invention relates to lubricating oil technology, in particular to an environment-friendly heavy-duty lubricating oil and a preparation method thereof. Background technique [0003] Octadecyloxythio nano calcium borate (T365) is composed of organic nano calcium borate extreme pressure antiwear agent, dialkyldithiocarbamate (ZDTC) antioxidant and anticorrosion agent, high temperature antioxidant, etc. Formulated with scientific formula. The octadecyloxythio nano calcium borate solves the problems of poor dispersion stability and hydrolysis stability of inorganic borates. . [0004] Neopentyl Polyol Ester (Neopentyl Polyol Ester) NPE-3, Neopentyl Polyol Es...
