Preparation method of lubricating oil with good nitrification resistance for natural gas engine |
| abstract |
The invention relates to a preparation method of lubricating oil for a natural gas engine with good nitrification resistance, and belongs to the technical field of lubricating oil. Aiming at the problem that lubricating oil used by a natural gas engine is easy to be nitrated, the viscosity index improver modified by the epoxy castor oil is adopted, and the lubricating oil can be utilized to improve the anti-nitration performance in the natural gas engine by hydroxylating the structure of the viscosity index improver. |
