Problems solved by technology

The main reason is that the coastal areas have high humidity, sea fog, high salt content in the atmosphere, and industrial pollution aggravates corrosion.
For example, when the aircraft is parked, the fuselage and the lower wall of the wing are close to the ground, and the water vapor on the ground evaporates and condenses on the lower wall, so that the fuselage-wing is in a humid environment for a long time, and water, condensation and water vapor enter the non-sealed riveting gap place, resulting in severe corrosion
At present, the aircraft surface coating system fails prematurely and lacks effective

Abstract

The invention relates to a long-acting water replacement type hard membrane corrosion inhibitor for aircrafts, and a preparation method thereof. The long-acting water replacement type hard membrane corrosion inhibitor is characterized by comprising the following raw materials by weight: 20-30 parts of a film forming agent, 30-40 parts of base oil, 1-10 parts of a corrosion inhibition additive, 5-10 parts of a dewatering additive, 1-5 parts of an antioxidant, 1-5 parts of a plasticizing agent, 1-5 parts of an emulsifier, 0.1-0.5 part of a color adjusting agent, and 5-10 parts of an auxiliary solvent. The prepared long-acting water replacement type hard membrane corrosion inhibitor has the following advantages that: the corrosion inhibitor has functions of strong rust resistance, long durability, good salt spray resistance, good dampness heat resistance and the like of the general corrosion inhibitor, further has characteristics of high flash point and low weight gain, meets aircraft flying requirements, has the strong permeability so as to easily penetrate and immerse into the overlapping and riveted structure of the aircraft, has the strong water replacement performance so as to replace the fine liquid droplet in the structural micropore, and concurrently provides corrosion protection functions for a variety of metals.

Description

technical field [0001] The invention relates to the technical field of manufacturing methods of corrosion inhibitors for aircraft, in particular to a method for preparing long-acting water-displacing hard film corrosion inhibitors for aircraft. Background technique [0002] At present, the corrosion problem of aircraft, especially aircraft that often fly in coastal areas, is relatively prominent. The main reason is that the coastal areas have high humidity, sea fog, high salt content in the atmosphere, and industrial pollution aggravates corrosion. For example, when the aircraft is parked, the fuselage and the lower wall of the wing are close to the ground, and the water vapor on the ground evaporates and condenses on the lower wall, so that the fuselage-wing is in a humid environment for a long time, and water, condensation and water vapor enter the non-sealed riveting gap , resulting in severe corrosion. At present, the aircraft surface coating system fails prematurely a...
