Problems solved by technology

U.S. Patent No. 4,844,825 discloses an extreme pressure additive based on chlorinated petroleum wax, which can effectively improve the lubrication and anti-friction performance of internal combustion engines. However, in order to neutralize the metal corrosion caused by chlorides, a large amount of alkaline sulfonic acid must be added Salt, so that the sulfur content cannot be lower than 1%
US Patent US7,423,000 discloses an extreme pressure additive that does not contain phosphorus and metal compounds, but the use of sulfur-containing additives is unavoidable
U.S. Patent No. 6,588,393 discloses a metal phosphate compound extreme pressure additive with low sulfur content (5-250ppm). Although the sulfur content is extremely low, the phosphorus content cannot meet the GF-4 and GF-5 standards

Abstract

The invention discloses a ceramic alloy composite functional coupling agent and a preparation method of the ceramic alloy composite functional coupling agent. The coupling agent is prepared from mixed sulphur amine phosphate ester, molybdenum oxide, carbonic acid rare earth, boric acid and calcium sulfonate of 100 to 4.5-5 to 4.5-5 to 12-17 to 12-17; the mixed sulphur amine phosphate ester is prepared by reacting coconut fatty acid and triethanolamine with phosphorus pentasulfide and capryl alcohol. The addictive is an oil-soluble ceramic alloy composite functional coupling agent and can be used as a friction improver, an anti-wear agent and a clearing agent for lubricating oil specially for internal combustion engines, so that the oil-saving effect is obvious; moreover, the addictive also has the advantages of energy conservation and environmental protection because of rare earth elements and low-sulphur low-phosphorous chloride-free contents.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to an oil-soluble ionic ceramic alloy composite functional coupling agent and a preparation method thereof. Background technique [0002] Where there is movement, there is friction, and where there is friction, there is lubrication. The main body of this kind of lubrication is lubricating oil and grease. At present, lubricating oil and grease products are almost used in various fields of the national economy, and they are the blood of industrial operations. It involves everything from transportation, metal processing, power machinery and equipment to construction and various electrical appliances. Over the past half a century, with the continuous renewal of mechanical equipment, its application range has been continuously expanded. The lubricating oil and grease products processed by petroleum refining alone are far from meeting the objective requirements in terms of pe...
