Abstract

The invention discloses a composite nano-lubricating oil additive with self-repairing function and a preparation method thereof, belonging to the technical field of lubricating oil. The components of the lubricating oil additive of the present invention are as follows in parts by mass: 20-30 parts of modified composite nanoparticles, 10-20 parts of ultrafine mineral powder, 5-10 parts of sodium alkylbenzene sulfonate, and 3-6 parts of antiwear agent And 3‑5 parts of preservatives. The present invention aims at the problems of easy aggregation and poor dispersion of nanoparticle additives in the prior art. Copper particles, nano-titanium dioxide, graphite and boron nitride with flake structure are selected as nanoparticle additives, and oleic acid coating, ultrasonic dispersion and It is modified by high-speed ball milling, supplemented by ultra-fine mineral powder, which can quickly and effectively fill surface scratches to repair mechanical damage. The two cooperate with each other to increase the lubricating effect of lubricating oil and prolong the service life of lubricating oil. Significant anti-friction effect.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a composite nano lubricating oil additive with self-repairing function and a preparation method thereof. Background technique [0002] Friction and wear are one of the most important forms of damage and failure of materials and equipment. How to effectively control friction, reduce wear, and improve lubrication performance has become an important measure to save energy and materials and shorten maintenance time. Lubricant is currently the most effective measure to reduce friction and wear, and the use of additives is the most important and effective way to improve oil performance. However, the usual anti-wear additives contain S, Cl and other elements that not only corrode the machine but also pollute the environment. Therefore, research and development of energy-saving, pollution-free, high-efficiency additives to replace the original additives has always be...
