Environment-friendly high-performance antiwear agent

Abstract

The invention discloses an environment-friendly high-performance antiwear agent. The environment-friendly high-performance antiwear agent is prepared from the following preparation raw materials in parts by weight: 100 parts of sulfonated graphene, 8 to 12 parts of terpinyl acetate, 4 to 6 parts of nano molybdenum disulphide, 14 to 16 parts of anionic surfactant and 55 to 75 parts of solvent soil.

Description

technical field [0001] The invention belongs to the field of oil product technology development, in particular to an environment-friendly high-performance anti-wear agent. Background technique [0002] The most important function of a lubricant is to reduce friction and wear, and in some cases relative motion of two bearing surfaces is only possible when the lubricant is present. Lubricants mainly play the role of reducing friction and slowing wear in machinery, so as to ensure the effective and long-term operation of machinery, that is, lubricate. Secondly, it plays a cooling role. The lubricant can take away the heat generated during mechanical friction, maintain a certain thermal balance state, control the machine to work within a certain temperature range, and prevent the temperature from rising and damage the parts. [0003] In the classical lubrication theory, lubrication is divided into fluid lubrication and boundary lubrication. In boundary lubrication, when the me...

Problems solved by technology

For example, chlorine-based antiwear agents have been banned by some countries such as the United States and Western Europe because of their toxicity problems; lead naphthenate has gradually been phased out due to ecological and toxic problems; sulfur-based, phosphorus-based anti-wear agents and ZnDDP are P and S will poison the catalyst in the exhaust gas converter, affect the measurement accuracy of the oxygen sensor and the toxicity to the ecological environment, which have been limited by international regulations, and boron antiwear agents also have dispersion stability and water sensitivity problems, etc. Wait

[0006] Zinc dialkyl dithiophosphate (ZnDDP) is currently the most widely used antiwear agent, but the phosphorus-containing conversion products of ZnDDP will be used in catalytic converters to reduce harmful gas emissions such as nitrogen oxides (NOx) in automobile exhaust Catalyst poisoning and affect the oxygen sensor; ZnDDP will produce ash to block the filter system, which will have a negative impact on the particulate filter of the diesel engine; the element Zn will cause electrochemical corrosion of certain alloy bearings (mainly silver and lead-containing parts); Under the working conditions above 160°C, it will lose anti-oxidation and extreme pressure anti-wear properties due to rapid decomposition

However, boron compounds are prone to hydrolysis
