Problems solved by technology

The disadvantage is poor repair ability
[0004] The advantages of adding nano-copper and zinc are wear resistance and wear reduction, and outstanding repair ability. The disadvantage is that the repair ability is too strong, and the parts that should not be repaired are also repaired. At the same time, the addition of metal substances makes the oil sensor malfunction.

Abstract

The invention discloses a diamond nanometer copper compounded lubricating oil additive in nanometer technical domain and mechanical fluid oil technical domain, which is characterized by the following: the nanometer diamond and nanometer copper are prepared to lube oil additive with diverse functional requirement; the high lubricating and high-intensity low restoring type fits for precision equipment, new device, high-grade car and gearbox and can diminish adding quantity of nanometer copper; the high lubricating and high-intensity high restoring type fits for wearing machinery and equipment and car and can enlarge the adding quantity of nanometer copper power. This invention possesses good dispersibility and does not need stirring and so on disposing craft.

Description

technical field [0001] The technology of the invention relates to the technical field of nanotechnology and mechanical lubricating oil, more specifically, the technical field of preparing nano microemulsions stably dispersed in lubricating oil with nano-diamond and nano-copper. Background technique [0002] Every leap in lubricating oil quality is essentially the result of the development of additives. The quality of most lubricating oils is improved by adding a variety of organic or inorganic, liquid or solid additives, and through physical or chemical adsorption and Chemical reaction to achieve good lubrication effect. Due to their high specific surface area and unique chemical and physical properties, nanoparticles have been widely valued in the field of new materials. At present, there are mainly two types of nano-scale lubricating oil additives: one is to use nano-diamond as a medium, such as the published patent technology 200410097197, 200410067742. The other is to ...
