Abstract

The invention discloses Miller amino carbon nitrogen compound nanoparticles and a diesel engine oil composition containing the same, belonging to the field of production of lubricating oil. The Miller amino carbon nitrogen compound nanoparticles are synthesized from ammonium chloride and cyanamides under the action of vertical static pressure of 40-250 MPa. The Miller amino carbon nitrogen compound nanoparticles have the characteristics of favorable suspension property, high oil film strength, favorable sealability, high dispersity, high abrasion resistance and the like, and can enhance the engine power. The diesel engine oil composition is blended from lube base oil, carbon nitrogen compound nanoparticles and the like, can reduce the abrasion of the main bearing, connecting rod bearing, valve system, piston and the like, and has high popularization value.

Description

technical field [0001] The invention relates to the field of lubricating oil production, in particular to a milleramide-based carbonitride nanoparticle and a diesel engine oil composition containing the carbonitride nanoparticle. Background technique [0002] With the development of modern mechanical equipment and internal combustion engines in the direction of high performance such as high speed and high load, the lubricating oil used in production and life requires multiple functions such as good load, anti-wear performance and high-temperature oxidation resistance, and the quality of lubricating oil mainly depends on Composition, nature and category of additives. At present and in the future, lubricating oil additives are developing towards the trend of low ash content, low pollution and multi-function. [0003] Researchers have found that many nitrogen-containing heterocyclic compounds and their derivatives have one or more excellent properties in anti-oxidation, anti-c...
