Abstract

The invention discloses a special water displacement type anti-corrosion agent applied to airplanes. The anti-corrosion agent is prepared from the following components in percentage by weight: 40-50% of a solvent, 30-50% of a film forming agent, 5-10% of a drier, 1-5% of a flexibilizer, 0.1-2% of a water displacement agent, 0.1-2% of a corrosion inhibitor, 0.1-2% of a flatting agent and 0.1-0.3% of a dye. All the components are uniformly mixed according to a ratio to form uniform transparent yellow to brown liquid. The durability of the anti-corrosion agent in the salt spray test can reach 1500 hours, is excellent in water displacement property, can achieve surface solidification in three hours, and is easy to remove; the operation time is reduced.

Description

technical field [0001] The invention relates to the field of metal preservatives, in particular to a water-displacing preservative used in the maintenance process of civil aviation aircraft and a preparation method thereof. Background technique [0002] Corrosion is a major problem encountered in the maintenance process of civil aviation aircraft. Corrosion-related aircraft repairs have always accounted for the vast majority of airline maintenance costs, and airlines around the world pay billions of dollars for corrosion repairs every year. According to the 1983 statistical report of the International Aviation Association, the corrosion repair expenditure corresponding to every flight hour of the aircraft has reached 10 to 24 US dollars. This cost does not include the large inventory of aviation materials prepared by the airline to ensure the normal operation of the aircraft and the repair loss caused by unplanned parking due to corrosion. [0003] Corrosion can cause stru...
