Abstract

The invention is applicable to the field of nanometer lubricating additives, and provides an antifriction agent containing modified nanometer hexagonal boron nitride, a preparation method of the antifriction agent, and lubricating oil. The antifriction agent comprises the following components: the modified nanometer hexagonal boron nitride, a cleaning agent, a stabilizing agent and nitrogen-containing borate, wherein the modified nanometer hexagonal boron nitride is nanometer hexagonal boron nitride modified by polydopamine and long-chain alkylamine. The multifunctional non-toxic nitrogen-containing borate is selected as a basic friction reducer, has excellent extreme-pressure anti-wear and anti-friction properties, very good oxidation stability and excellent sealing adaptability, is non-toxic and odorless, is beneficial for environmental protection, and has better performance than phosphorus-based and sulfur-based additives; and in addition, the modified nanometer hexagonal boron nitride having been subjected to mussel bionic surface modification is selected as a nanometer lubricating additive, and the antifriction performance of nitrogen-containing borate is improved by utilizingthe ball effect and the self-repairing effect of nanometer particles.

Description

technical field [0001] The invention belongs to the field of nano lubricating additives, in particular to a friction reducer containing modified nano hexagonal boron nitride, a preparation method thereof and a lubricating oil. Background technique [0002] Engineering materials are damaged from the free surface of the material due to friction, wear and corrosion. Statistics show that one-third or even half of the world's energy is consumed to overcome friction. Reducing friction and reducing wear is of great significance to the development of the national economy. As a nano-lubricating additive, nanoparticles can greatly improve the performance of lubricating oil. This is because it can realize the "ball" effect, film-forming effect and self-repairing effect on the friction contact surface, thereby reducing friction, reducing wear, and improving oil quality. Energy utilization efficiency and service life of parts. Nanoparticles have broad prospects as a new type of lubrican...
