Problems solved by technology

However, the existing technology does not have obvious self-repair function because the additive contains a very small amount of molybdenum and tungsten atoms, so it still needs to be improved in terms of improving the power and economy of the engine.

Abstract

The invention provides a lubricating oil additive and a preparation method thereof. The lubricating oil additive comprises the following components: basic lubricating oil, a dispersing agent, an antioxidation anti-corrosion agent and an anti-foaming agent, and is characterized in that the lubricating oil additive also comprises metal or alloy micro-powder with a particle size of 20-200 nm. The preparation method of the lubricating oil additive comprises the following steps: mixing the above components according to a certain proportion, and carrying out ball-milling homogenization treatment toobtain a finished product. The lubricating oil additive disclosed by the invention is added into engine oil and can perform self-repairing on a worn part, so that the output power of an engine is improved, the cylinder pressure is increased, toxic compounds in exhausted tail gas are greatly reduced, the friction is reduced, the surface wear resistance is enhanced, the noise is reduced, the starting performance is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a lubricating oil additive with self-repairing, friction-reducing and wear-resistant functions and a preparation method thereof. Background technique [0002] During the operation of vehicles or machinery, wear and tear will reduce their working performance, increase fuel consumption or increase power consumption, and the wear and tear of engines in vehicles will also increase the content of toxic compounds in exhaust gases and pollute the atmosphere. This not only affects the service efficiency of machinery, but also requires regular maintenance, resulting in energy waste. [0003] Chinese patent application "lubricating oil containing organic molybdenum and tungsten additives", the application number is 92100282.3, the publication number is CN1074474A, and the publication date is July 21, 1993. In this patent application, 0.03 to 10 (weight)% of dialkyl dithiophosphoric acid sulfurized molybdenum oxide and dialkyl dithiophos...
