Problems solved by technology

Since the added copper and nickel are high-energy metals without any protection on the surface (otherwise it does not need to be operated in a vacuum), they are often used as catalysts in the petrochemical industry. Therefore, during use, the lubricating oil body will deteriorate and the acidity will increase. cause corrosion
Unprotected agglomerated particles will form large hard agglomerates that cannot be dispersed in the oil, which not only cannot ensure suspension but also aggravate friction and wear

Abstract

The present invention discloses a repairing type lubricating oil additive and its preparation method. Its composition includes 1-10% of aluminium, titanium, zinc and tin granules whose grain size is 10-200 nm, their weight ratio of 5.5-6.5:1.5-2.5:0.5-1.5:0.5-1.5, 88-98% of basis oil for finished product lubricating oil and 1-2% of dispersing additive. Its preparation method incldues the following steps: placing the above-mentioned all the materials into same container, mechanically-stirring and mixing for 20-40 min., placing the mixture and said container into an ultrasonic oscillator to make ultrasonic oscillation for 20-40 min. so as to obtain the invented lubricating oil additive with good repairing effects.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to a repairing lubricating oil additive based on nanometer metal particles and a preparation method thereof. Background technique [0002] In mechanical equipment, where there is relative movement, such as various friction pairs, friction will occur, and the accumulation of friction will cause wear on the surface of the friction pairs. The existence of friction consumes extra energy and reduces mechanical efficiency. The occurrence of wear and tear will gradually cause the parts to lose their dimensional accuracy and fail, resulting in the scrapping of equipment. For internal combustion engines, the occurrence of wear and tear will also lead to a decrease in the sealing of the cylinder, resulting in insufficient fuel combustion, which will pollute the environment when it is discharged into the air. Therefore, in the operation of mechanical equipment, va...
