Abstract

The invention discloses paint for aircraft stealth and a preparation method thereof. The paint is prepared from the following raw materials: hydroxylated acrylic resin, polyurethane, water-based acrylic resin, nickel powder, isophorone diisocyanate, zinc powder, triethanolamine, zinc chromate, triethylamine, ammonia water, zinc oxide, zirconium oxide, iron oxide red and a thickening agent; the paint can be used for resisting ultrahigh-frequency and high-strength radar detection and has good electromagnetic parameters; the density of a coating is 0.1g / cm<3>-0.5g / m<3>; the electric conductivity is 0.01W / m.k-0.016W / m.k, and the heat insulation performance is good; the surface is dried at 25 DEG C after 10min-50min, and the paint is completely dried after 4h-8h; a coated film is flat and smooth and has the effects of resisting humidity, atmosphere, acid rain, seawater and salt-fog corrosion; the rigidity is 6H-10H; and the paint has high adhesion force, impact resistance and good abrasion, can be widely produced and can continuously replace an existing material.

Description

technical field [0001] The invention relates to the technical field of aircraft coatings, in particular to an aircraft stealth coating and a preparation method thereof. Background technique [0002] Infrared stealth paint refers to the special functional paint used to weaken the infrared characteristic signal of the weapon system and has reached the requirements of stealth technology. It is mainly aimed at the detection of infrared thermal imaging cameras. Shapes in the thermal imager, making them less likely to be seen and identified. The most effective way to achieve infrared stealth is to control the surface temperature of the target and minimize the deviation between the target and the background. Materials used for thermal infrared stealth should have satisfactory thermal infrared emissivity or strong temperature control ability; have a reasonable surface structure; have low solar energy absorption rate; and be compatible with stealth coatings in other frequency bands....
