Lubricating oil having cleaning function

Abstract

The invention discloses lubricating oil having a cleaning function, which relates to the technical field of lubricating oil, and is used for solving the problem that the existing lubricating oil is poor in cleaning function. The lubricating oil comprises ordinary lubricating oil and a copper-based composite powder material which is uniformly dispersed in the ordinary lubricating oil, wherein the mass ratio of the copper-based composite powder material to the traditional lubricating oil is (0.01 to 3): 100, and the particle size of the copper-based composite powder material is less than or equal to 10 micrometers. The lubricating oil having the cleaning function not only can polish a friction surface and eliminate harmful substances clung to the friction surface such as accumulated carbon and oil, but also can absorb and remove harmful substances such as the accumulated carbon and oil separated from the friction surface by virtue of a great amount of spherical or spherical-like copper-based composite powder material, and the harmful substances can flow together with the lubricating oil, so that an oil path can be dredged, the health and stable operation of an engine can be facilitated, the noise and vibration can be reduced, the output power of the engine can be increased, the replacement period of engine oil can be prolonged, and the maintenance cost can be reduced.

Description

[0001] This application claims the priority of Chinese Patent Application Nos. 201410690532.2 and 201410688095.0 filed on November 25, 2014. technical field [0002] The invention belongs to the technical field of lubricating oil, and specifically relates to a lubricating oil mainly used in engines and having a cleaning function. Background technique [0003] In order to reduce the wear caused by contact friction between the friction pairs in relative motion, it is generally necessary to add lubricating oil to give good lubrication to the friction parts. When the lubricating oil flows to the friction parts, an oil film will be formed on the friction surface , thereby reducing the friction between the friction parts. For mechanical equipment, adding lubricating oil can improve work efficiency and reduce power loss, but for engines, it is not enough to solve lubrication problems, because: [0004] 1. The dust inhaled from the air when the engine is working, and the metal debr...
