Problems solved by technology

[0002] At present, since domestic aircraft are mainly Boeing and Airbus, the water-based aircraft surface cleaners used are mainly foreign designated suppliers and domestic products that have passed the inspection of the Civil Aviation Administration of China and obtained airworthiness certificates. Foreign products are subject to tariffs, etc. The reason is that the price is very high. Domestic products generally use non-environmental protection components, which is not conducive to environmental protection and the requirements of sustainable development.
[0003] The active agent components used in existing products are mostly nonylphenols, which are not easy to degrade and have adverse effects on organisms. The production and use have been banned by many countries

Abstract

The invention relates to a water-based airplane surface cleaning agent, which is prepared by uniformly mixing the following components in percentage by weight: 21 to 30 percent of degradable surfactant, 5 to 7 percent of metal corrosion inhibitor, 0.3 to 2 percent of pH regulating agent, 1.7 to 5 percent of stabilizer, and the balance of deionized water. A preparation method comprises the following steps: (1) weighing the pH regulating agent, the degradable surfactant, the metal corrosion inhibitor, the stabilizer and the deionized water according to the ratio of weight percent; (2) adding the pH regulating agent, the metal corrosion inhibitor, the degradable surfactant and the stabilizer into the deionized water at the room temperature of between 23 and 25 DEG C; and (3) stirring the liquid at constant speed of 60 to 80r / min for 20 to 40 minutes to ensure that no bubble is generated in the liquid to prepare the cleaning agent after uniform mixing. The invention has scientific and reasonable formula and simple process without special equipment, and the cleaning agent has the advantages of strong cleaning capability, short cleaning time, low cost, high efficiency and is safe and reliable for use.
