Abstract

The invention discloses an environment-friendly heavy-duty gear lubricant prepared from NPE (neopentyl polyol ester) with addition of hexadecyl calcium borate. A formula of the environment-friendly heavy-duty gear lubricant is characterized in that 0-0.96% of hexadecyl calcium borate T362, 0-0.48% of dialkyl pentasulfide Rc2540, 0-0.40% of phosphorus star, 0-0.40% of sulphurized isobutylene T321, 0-0.72% of benzotriazole aliphatic amine T406E are added to NPE-3, and the lubricant is prepared from the materials through heating and uniform mixing. A formula of the environment-friendly heavy-duty gear lubricant comprises components as follows: 0-0.96% of hexadecyl calcium borate T362, 0-0.48% of dialkyl pentasulfide Rc2540, 0-0.40% of phosphorus star P120, 0-0.40% of sulphurized isobutylene T321, 0-0.72% of benzotriazole aliphatic amine T406E. The environment-friendly heavy-duty gear lubricant has higher bearing capacity, better environmental protection property and better lubrication and friction reduction performance.

Description

technical field [0001] The invention relates to lubricating oil technology, in particular to an environment-friendly heavy-duty gear lubricating oil. Background technique [0002] Add hexadecyl calcium borate (T362), dihydrocarbyl pentasulfide (RC2540), phosphorus star (P120), isobutylene sulfide (T321), and benzene to synthetic oil neopentyl polyol ester (NPE-3). Triazole fatty amine salt (T-406E) was tested in 5 kinds of additives, and the artificial neural network method was used to optimize the calculation, and the verification was carried out. Because it contains sulfur and phosphorus elements, the load can be as high as 1970N. The disadvantage is that it contains more sulfur and has a certain degree of corrosion. [0003] Calcium Hexadecylborate (T362) Light amber transparent oily liquid. Under the catalysis of sulfide, it is formed by esterification of borate, and the molecular structure does not contain metal atoms. It is a phosphorus-free, ash-free, low-sulfur...
