Embodiment 1

[0021] Add neopentyl polyol ester (NPE-3) oil to account for neopentyl polyol ester: lubricating oil additive formula selection: sulfur nitrogen borate: 0.96%, dihydrocarbyl pentasulfide: Rc2540: 0.36%, phosphorus Star 0.10%, sulfurized isobutylene (T321) 0.20%, benzotriazole fatty amine salt T406E: 0.45%, stir well and heat at 80°C for 40 minutes to obtain the product.

Embodiment 2

[0023] Adding neopentyl polyol ester (NPE-3) base oil to the weight percentage of neopentyl polyol ester: sulfur nitrogen borate: 0.6%, dihydrocarbyl pentasulfide: Rc2540: 0.42%, phosphorus star 0.15% , sulfurized isobutylene (T321) 0.10%, benzotriazole fatty amine salt T406E: 0.09%, mix well and heat at 80°C for 40 minutes to get it.

Embodiment 3

[0025] Adding neopentyl polyol ester (NPE-3) base oil to the weight percentage of neopentyl polyol ester: sulfur-containing nitrogen borate 0.72%, dihydrocarbyl pentasulfide: Rc2540: 0.24%, phosphorus star 0.30% , sulfurized isobutylene (T321) 0.30%, benzotriazole fatty amine salt T406E: 0.63%, mix well and heat at 80°C for 40 minutes to get it.

Abstract

The invention provides environment-friendly lubricating oil prepared from neopentyl polyol ester with addition of multiple additives comprising borate containing sulfur and nitrogen. 0-0.96% of borate containing sulfur and nitrogen BSN, 0-0.48% of dialkyl pentasulfide Rc2540, 0-0.40% of star-level phosphorus, 0-0.40% of sulphurized isobutylene (T321) and 0-0.72% of benzotriazole T406E are added to neopentyl polyol ester (NPE-3) and are heated and mixed uniformly, and the environment-friendly lubricating oil is prepared. A formula of the environment-friendly lubricating oil comprises the components of 0-0.96% of borate containing sulfur and nitrogen BSN, 0-0.48% of dialkyl pentasulfide Rc2540, 0-0.40% of star-level phosphorus P120, 0-0.40% of sulphurized isobutylene (T321) and 0-0.72% of benzotriazole T406E. The environment-friendly lubricating oil has higher bearing capacity, better lubricating and anti-wear performance and environmental protection characteristics.

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 boron-based additives sulfur nitrogen borate BSN, dihydrocarbyl pentasulfide (RC2540), phosphorus star (P120), sulfurized isobutylene (T321), and benzene trisulfide to synthetic oil neopentyl polyol ester (NPE-3) The experiment was carried out in 5 kinds of additives of azole fatty amine salt (T-406E), 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 1774N. The disadvantage is that it contains more sulfur and has a certain degree of corrosion. [0003] Boron series additives are non-toxic and tasteless and have good extreme pressure, anti-wear, anti-friction, thermo-oxidative stability, anti-corrosion, sealing adaptation and other properties.
