Aviation component cleaning agent and preparing method

Abstract

The invention provides an aviation component cleaning agent and a preparing method. The cleaning agent is composed of an n-alkanes base solvent, a butyl cellosolve active agent and an N,N'-diethylene propylene diamine active agent. A nitrogen tank is inflated with nitrogen generated in a nitrogen machine, and the nitrogen in the nitrogen tank is blown into a tempering kettle; the n-alkanes base solvent is pumped into the tempering kettle from the interior of a solvent tank, and the butyl cellosolve active agent and a passivator which is the N,N'-diethylene propylene diamine active agent are pumped into the tempering kettle through an additive tank; and water bath heating is conducted, so that the temperature in a reaction kettle ranges from 50 DEG C to 55 DEG C, and stirring at constant speed is conducted for 3 h. Due to the fact that the n-alkanes is adopted as the base solvent, and the butyl cellosolve active agent and the passivator are adopted as the N,N'-diethylene propylene diamine active agent additive, the cleaning agent is obtained through cooling, filtering and filling. The cleaning agent is suitable for serving as aviation component cleaning agent, and the preparing method is applied.

Description

technical field [0001] The invention proposes a cleaning agent in the field of organic chemistry, which is mainly used for cleaning aviation parts. Specifically, it relates to a cleaning agent for aviation parts and a preparation method thereof. Background technique [0002] At present, 180# aviation washing gasoline is usually used for cleaning aviation parts. 180# aviation washing gasoline has a low flash point, which is easy to cause combustion and explosion, and has low safety; 180# gasoline is obtained from petroleum refining fractionation, which is limited by crude oil refining process and distillation process, and contains a small amount of sulfides, aromatics, etc. , unstable and toxic to humans. Therefore, developing a kind of cleaning agent that can replace 180# aviation washing gasoline, has safe and non-toxic characteristics is the problem urgently in need of solving at present. Contents of the invention [0003] In order to make the cleaning agent for aviat...
