Abstract

The invention provides a nano wear reducing additive preparation formula, which is especially used for the wear reducing additive for automobile engine lubricating oil. The nano wear reducing additive is prepared by uniformly stirring 23-43% of nano carbon particles, 12-26% of nano molybdenum disulfide, 28-39% of polytetrafluoroethylene, 5-9% of isopropanol and a proper amount of anti-grinding agent. The nano wear reducing additive is capable of effectively reducing pressure and reducing resistance, the employed nano carbon particles and nano molybdenum disulfide have absolutely effective friction effect, lubricating oil state is stable, optimum lubrication effect can be reached, and oil-way obstruction is difficultly generated.

Description

technical field [0001] The invention provides a preparation formula of a nano anti-friction additive, in particular for the preparation of an automobile engine lubricating oil anti-friction additive. Background technique [0002] With the continuous development and popularity of nano-materials, nano-materials have become the main materials that cannot be ignored, and are widely used in lubricant additives. The current additives have their shortcomings and cannot meet various needs. At present, scientists have passed Repeated experiments have proved that flake nano-graphite is easier to spread and form a film on the friction surface, and the additive made of nano-graphite is far superior to traditional additives, with better lubricating performance. It can run normally for more than 15 hours, and the effect of reducing wear is excellent. Contents of the invention [0003] The object of the present invention is to provide a preparation formula of nano anti-friction additive...
