Abstract

A purpose of the present invention is to provide a novel environmental protection non-sulfur-phosphorus metal magnetic lubricating oil additive with characteristics of simple production method, low cost, good oil solubility and high yield, and a preparation method thereof. The novel metal magnetic lubricating oil additive is characterized in that the additive is prepared from mixed amide, molybdenum oxide, tungsten oxide, hydroxyethyl ethylene diamine and ammonia water according to a weight ratio of 100:8.5-10:8.5-10:10-15:10-15, wherein the mixed amide is prepared through carrying out a reaction of tall oil, diethanolamine and methyl oleate. The additive is an oil-soluble metal magnetic tungsten-molybdenum-nitrogen complex, is a friction modifier, an anti-wear agent and an antioxidant for internal combustion engine motor lubricating oil, has a significant oil saving effect, and does not contain sulfur and phosphorus so as to further provide advantages of energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to the synthesis of oil-soluble metal magnetic tungsten and molybdenum lubricating oil additive compounds. Background technique [0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to the lubricating oil. The traditional lubricating oil additives are sulfur, phosphorus or chlorine type anti-wear agents, which are corrosive to friction pair materials. selective. In particular, lubricating oil additives containing elements such as sulfur, phosphorus or chlorine will discharge a large amount of waste water, waste gas and pollutants during production and use, thereby causing pollution to the environment. [0003] In recent years, with the rapid development of the automobile industry, especially the growing demand for energy saving, emission reduction, low-carbon and environmen...
