Problems solved by technology

[0005]However, the extremely fine grains of nanoparticles cause the particles to have huge surface energy, coupled with the attractive force between particles, the tendency of automatic aggregation between particles is very large. Larger block aggregates can be formed after a certain period of time, so there is a problem of poor dispersion stability in oil products
In addition, the lubricant containing MoS2 may chemically react with the contact surface, thereby generating frictional heat, causing oxidation, and negatively affecting the oxidation stability of the oil; when the lubricant contains organic PTFE, the lubrication The thermal conductivity and oxidation resistance of the oil will deteriorate
[0006]And as a lubricating oil additive, nanoparticles have a single function, and the nanoparticles are agglomerated and dispersed unevenly in the base oil, resulting in poor anti-wear and anti-friction effects. Can not play a good lubrication effect

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a vegetable oil-based nano lubricating oil additive and a preparation method thereof. Background technique [0002] Friction is an unavoidable natural phenomenon. The fuel used to reduce friction and wear of mechanical parts accounts for 1 / 3 of the total fuel consumption. In addition, friction can also cause useless loss of mechanical energy, shorten machine life, and reduce mechanical efficiency. . In order to solve the above problems, it is particularly important to find substances that can reduce friction and wear, so lubricating oil is often added, and in order to improve the tribological properties of lubricating oil, appropriate additives are often added to lubricating oil. [0003] Lubricating oil additives refer to a single agent or a mixture of several single agents that are mixed according to a certain proportion and blending technology and can meet...
