Environment-friendly efficient water-based dry cleaning agent for airplane maintenance and preparation method thereof

Abstract

The invention relates to an environment-friendly efficient water-based dry cleaning agent for airplane maintenance. The environment-friendly efficient water-based dry cleaning agent is composed of thefollowing components in parts by weight: 5-20 parts of compound surfactant, 0.1-3 parts of complexing agent, 2-12 parts of composite metal corrosion inhibitor, 0.05-0.6 part of film-forming agent, 0.5-12 parts of cosolvent and the balance of deionized water (complementing to 100 parts). The dry cleaning agent contains no hazardous substances, such as heavy metal, strong base, nitrite, phosphorus,amine and amide, contains no high-toxicity and high-volatility organic solvents, such as hydrochloric ether, phenol and ketone, is physiologically harmless, is easy to biodegrade and is mild, free from flashing point, multifunctional, high-efficient, safe, environment-friendly and energy-saving; the dry cleaning agent has excellent effects of cleaning and protecting paint, is capable of quickly and thoroughly cleaning various light and heavy oil stains and complex dirt on airplane surface, has an excellent dry cleaning effect, can keep clean for a long time and is capable of effectively reducing frictional resistance in flight; after dry cleaning, a protective layer is formed, so that the generation rate of dirt on the airplane surface is reduced.

Description

technical field [0001] The invention belongs to the technical field of cleaning and maintenance, and relates to an aircraft dry cleaning agent, in particular to an environment-friendly and efficient water-based dry cleaning agent for aircraft maintenance and a preparation method thereof. Background technique [0002] As the most commonly used means of transportation, aircraft will be exposed to various pollutants during daily flight and parking, such as air, wind and sand, fuel exhaust, waste oil, salt spray, acid spray, etc. It is inevitable that some smoke, oil, carbon deposits, dust, oxides and other pollutants will be attached. Deposited pollutants not only affect the appearance of the aircraft, but also reduce the surface finish of the fuselage, increase frictional resistance, increase flight fuel consumption, increase fuel consumption rate, and may increase static electricity accumulation, which is not conducive to safe flight. What's more serious is that these pollut...

Problems solved by technology

[0006] Chinese patent CN101580772A discloses a kind of aircraft exterior cleaning agent, wherein used mineral oil, alcohol ether etc., used terpineol, limonene etc. in CN1919992A, used solvent gasoline, propylene glycol etc. in CN104947131A, used more alcohol in CN102994271A Ether, edible alcohol, the use of these organic solvent raw materials has high cost, and the use process is harmful to human health, difficult to degrade, and harmful to the environment.

The aircraft fuselage surface cleaning agent disclosed in CN1621505A uses phosphorus-containing additives, and CN1635181 uses nonylphenol-containing substances. These substances all have the problems of endangering health and polluting the atmospheric environment, and most of them have been restricted or banned from use.

[0007] In addition, some other water-based aircraft cleaning agents can only effectively protect one or part of the metal materials or surface treatment layers used in aviation, and cannot effectively protect various metal materials, and cannot effectively achieve Various coatings are protected, and the anti-pollution ability of the coating is poor after washing; the water consumption is large during cleaning, and water pipes need to be connected. Due to site restrictions, there is a possibility that water may enter sensitive components such as aircraft probes, and the safety factor is low.
