Abstract

The invention discloses a fatty acid diesel anti-wear agent. The fatty acid diesel anti-wear agent is characterized in that a composition formula is prepared from the following component formulas: (1)the fatty acid diesel anti-wear agent, and (2) 20 parts by weight of organic nitrogen-molybdenum fullerene lubricant. The fatty acid diesel anti-wear agent is prepared from the following compositions: (1) tall oil acid, (2) long-chain fatty acid ester molecules 1, and (3) long-chain fatty acid ester molecules 2. According to the fatty acid diesel anti-wear agent, through four-ball machine testing, the wear scar diameter is significantly decreased, the anti-friction performance of lubricants used by a gasoline engine and a diesel engine is effectively improved, and the mist spray performance of the diesel can further be effectively improved.

Description

technical field [0001] The invention relates to a composition and a preparation method of a fatty acid diesel antiwear agent. The invention belongs to the field of lubricating materials, in particular to a composition and a preparation method of an efficient and environment-friendly fatty acid diesel antiwear agent. Background technique [0002] The quality of diesel oil has been continuously improved, and the sulfur content of national VI diesel oil is less than or equal to 10PPM. The sulfur and viscosity in diesel oil have dropped significantly, and the lubricity of diesel oil has also decreased. Therefore, it is necessary to improve the lubricating properties of low sulfur diesel oil. [0003] Diesel lubricity improvers consist of polar compounds that adsorb on metal surfaces. A protective film is formed on the metal surface, which can reduce the friction between metal parts during movement. The degree of lubrication is thus significantly increased. There are mainly th...
