High-performance cleanser special for military aircraft engines and preparation method

Abstract

The invention discloses a high-performance cleanser special for military aircraft engines and a preparation method, and belongs to the technical field of engine cleaning. The cleanser comprises 4-6 parts of higher fatty acid sodium, 3-5 parts of sodium sulfate, 1-3 parts of phosphate salt, 2-5 parts of sodium citrate, 1-4 parts of alkanolamide, 3-5 parts of fatty acyl-peptide condensate, 1-3 partsof benzotriazole, 3-4 parts of triethanolamine, 2-5 parts of nano-metal oxide and 3-6 parts of organic solvent; the cleanser further comprises 1-2 parts of dichloromethane and 1-2 parts of dichlorofluoroethane. Compared with the prior art, the cleanser has the advantages that the cleanser can effectively clean the inside of an engine and prevent a lubricating oil passage from being blocked; the engine cleanser contains special decontamination components and can effectively dissolve and remove colloids, greasy filth and carbon deposits in an oil circulation system in the engine, the contaminants are discharged along with used oil, the oil fluidity is enhanced, the oil consumption and engine wear are reduced, and the service life of the engine is prolonged; generation of acidoids in the engine is inhibited, and the inside of the engine is protected.

[0002] At present, military engines are very different from civilian engines. Military engines are more inclined to high thrust and reliability under harsh working conditions. As the saying goes, they are strong, strong and durable; although most of the technologies of the two overlap, but The difference in design indicators has caused military engines to simply apply civilian engine technology. For example, the bypass ratio of military engines is lower than that of civilian aircraft and general transport aircraft; the flight envelope of fighter jets is much larger than that of transport aircraft, so the engine must be maintained at the worst It works stably under the working conditions. In order to meet the requirements of air combat, it is necessary to make a high-speed response to the control within a certain time. The afterburning thrust device-afterburning is adopted; the anti-surge ability of the military aircraft engine is far stronger. It is used for civilian engines, but on the whole, military engines have high utilization rate, high wear, high fuel consumption, and short service life. It is especially important to clean military aircraft engines, which can prolong the service life of the engines.

[0003] The patent with the application number 201310654270.X discloses an engine carbon deposit cleaner and its preparation method. The invention utilizes triethanolamine alkylbenzenesulfonate, triethanolamine oleate, organic solvent, nonylphenol polyoxyethylene ether, Prepared with dodecylamine polyoxyethylene ether and nano-CeO, the cleaning agent of this invention can clean carbon deposits without heating and stirring, has super penetrating power, and can clean small and complex Dirt removal inside parts, but this invention can not play a lasting effect on the cleaning of aircraft, especially military aircraft engines. For military engines, due to the frequent use of military engines, they need to be kept unblocked for a long time. It is particularly important, especially the carbon deposits will block the engine oil filter and cause damage to the engine. Therefore, an engine cleaning agent is needed to remove internal sludge, carbon deposits, colloids and other harmful substances, keep the interior of the engine clean, and enhance oil fluidity , reduce wear and prolong engine life
