Abstract

The invention relates to a tung oil-based aviation fuel anti-wear agent and a preparation method and application thereof, the tung oil-based aviation fuel anti-wear agent is a C36 unsaturated fatty acid dimer containing a monocyclic structure, and the content of the C36 unsaturated fatty acid dimer containing the monocyclic structure is greater than or equal to 85%, preferably greater than or equal to 95% by mass. The invention also provides a preparation method of the tung oil-based aviation fuel anti-wear agent. The tung oil-based aviation fuel anti-wear agent provided by the invention has good wear resistance and corrosion resistance, and meanwhile, the problem that the water separation index does not reach the standard is avoided.

Description

technical field [0001] The invention belongs to the field of aviation fuel antiwear agents, in particular to a tung oil-based aviation fuel antiwear agent and its preparation method and application. Background technique [0002] As the requirements of environmental protection regulations on engine emissions continue to be strict, the production process of aviation fuel mainly adopts acid-base refining, hydrofining or hydrocracking, so that the natural anti-wear components such as sulfur and aromatics in the distillate are removed, resulting in aviation Reduced fuel wear resistance may cause excessive wear of the fuel pump plunger spherical surface, resulting in insufficient fuel supply, and in severe cases, it may cause accidents such as parking in the air. In a jet engine, the lubrication of the fuel pump is guaranteed by the lubricating performance of the jet fuel itself, and the working life of the fuel system components, especially the rotating and oscillating parts, lar...
