Problems solved by technology

It has good dispersibility, extreme pressure performance and anti-wear performance, but its disadvantage is that the lubricating oil additive contains 0.1-50% dispersant and 0.1-30% synergist, based on the same reason as above , the existence of the dispersant and synergist of the additive has seriously affected its use function and industrial application; in addition, the usage amount of the lubricating oil additive is also very large, being 1-10% of the total amount of lubricating oil, resulting in increase in user costs

Embodiment Construction

[0044] The mechanism of action of the nano lubricating oil additive of the present invention:

[0045] Firstly, the oil-soluble nano-copper (or nano-copper alloy) and reactive nano-silicon The action mechanism of the nano lubricating oil additive composed of silicon of the present invention is analyzed.

[0046] (1) Repair and anti-wear performance and mechanism analysis of oil-soluble nano-copper (sports car experiment):

[0047] Add 30ml of oil-soluble nano-copper to 3L of SP series gasoline engine lubricating oil produced by Beijing Sunshine Lubricating Oil Co., Ltd., a Sino-US joint venture, and mix evenly. After the gasoline engine has been working normally for about half a month, take out the connecting rod bush for analysis , and compared with the connecting rod bearing of the SP series lubricating oil without oil-soluble nano-copper. The worn surface morphology was measured by a JSM5600LV scanning electron microscope, and the corresponding copper element surface dist...

Abstract

The present invention discloses one kind of nanometer lubricating oil additive, which consists of liposoluble nanometer copper or copper alloy and liposoluble nanometer silica. The nanometer lubricating oil additive of the present invention can realize the self repair of the worn part, and possesses the functions of saving oil, resisting abrasion, reducing noise, decreasing carbon deposit, raising power performance, etc. It has high dispersivity in lubricating oil, high oxidation stability and long term stability, and is favorable to solving different friction and wear problems in different work conditions.

Description

technical field [0001] The invention relates to a nano lubricating oil additive, in particular to a novel lubricating oil additive containing oil-soluble nano copper or nano copper alloy and reactive nano silicon dioxide. Background technique [0002] Lubricants are an integral part of machinery operation and maintenance. With the increasing load, speed, temperature and other working parameters of modern mechanical equipment, the original friction reducer and antiwear agent in lubricating oil can no longer fully meet the requirements of its antifriction and antiwear performance. Since the 1990s, with the in-depth research on nanomaterials and technologies, it has been found that nanoparticles have shown many excellent tribological properties in the field of lubrication. The friction and anti-wear performance has been greatly improved, and a new solution has been opened up for the long-term unsolved problems in the field of lubricating oil. [0003] There are many researche...
