Abstract

The invention discloses a preparation method of an aircraft stealth coating. The stealth coating comprises the following raw materials: chlorinated PVC resin, cobalt oxide, graphene oxide, diethyleneglycol, nickel chloride hexahydrate, zinc iron chromite brown spinel, sodium alginate, hydroxyethyl cellulose, aluminum paste, azobisisobutyronitrile, stearic acid, zinc oxide, iron oxide yellow, diphenyldichlorosilane, nano cuprous sulfide, manganese naphthenate and ultramarine blue; and the preparation method comprises the steps of grinding dispersion and spray coating. The stealth coating provided by the invention has the following technical effects: the stealth coating has a microwave frequency range of 8-18 GHz and three atmospheric windows including infrared wavelengths of 0.75-3 [mu]m,3-5 [mu]m and 8-14 [mu]m, thereby having multi-band wave absorbing effects; after 40-60 d artificial weathering aging is performed, the coating film has no discoloration, no gloss loss, no foaming andno falling, the elongation at break is 260-280%, the coating film has no foaming and no falling when being immersed into distilled water with temperature of 25 DEG C for 40-60 days, the melting pointis 350-450 DEG C, the impact strength is 60-100 kg / cm, and the coating film has no foaming and no falling when being immersed into sodium hydroxide for 12-14 days.

Description

Technical field [0001] The invention relates to stealth coatings, in particular to a method for preparing stealth coatings for aircraft. Background technique [0002] Stealth paint is a stealth material that is fixedly coated on the structure of the weapon system. According to its function, it can be divided into radar stealth paint, infrared stealth paint, visible light stealth paint, laser stealth paint, sonar stealth paint and multifunctional stealth paint. The stealth coating requires: chemical stability at a wider temperature; better frequency band characteristics; low surface density and light weight; high bonding strength, resistance to certain temperature and different environmental changes. [0003] Since radar reconnaissance is one of the most used and most effective reconnaissance methods in the world, radar stealth technology has naturally become one of the most important stealth technologies, and relevant departments at home and abroad have conducted a lot of research....
