Abstract

The invention discloses a nanometer maintenance agent for an engine, and a preparation method and application thereof, belonging to the field of preparation of lubricants. The nanometer maintenance agent for the engine comprises, by mass, 0.001 to 10% of an inorganic nano-material, 0.001 to 20% of nanometer organic molybdenum, 0.005 to 10% of a clearing agent and 0.005 to 10% of a dispersant, with the balance being a disperse medium. The nanometer maintenance agent for the engine prepared in the invention can be stably and uniformly stored for 36 months or above, has a sedimentation value of less than 3 and can be prepared, stored and transported at room temperature; and the preparation method is simple in process and free of production of waste water, waste gas and industrial residues, and meets requirements of environmental protection.

Description

technical field [0001] The invention discloses a nano engine maintenance agent and its preparation method and application, in particular to an engine nano maintenance agent used for lubricating mechanical equipment such as engines, gears, bearings, and its preparation method and application. Background technique [0002] For anti-friction and anti-wear effect, some solid particles can be added to lubricating oil. Such as graphite, molybdenum disulfide, Teflon, etc., their particle size is micron or submicron. Due to their unstable state in oil, their precipitates are likely to cause blockage of oil passages and accelerate the formation of sludge, so they are rarely recommended for use at present. [0003] With the heating up of nanotechnology, the work of adding nanomaterials to lubricating oil has done some exploration in recent years. For example, adding nano-metal particles (Cu, Fe, Ni, Co, etc.), nano-SiO 2 、Ti 3 (BO 3 ) 2 , nano-diamond, nano-organic copper, nano-...
