Abstract

The invention provides a preparation method for radar detection coating of an air vehicle. The radar detection coating is prepared from the following raw materials: epoxy resin, graphite, glycerol, ultrafine talcum powder, ammonium sulfate, chrome antimony titanium buff rutile, casein, propyl methyl cellulose, sodium hexametaphosphate, vinyl acetate, acetylene carbon black, zirconium oxide, iron oxide red, methyltrichlorosilane, quasi-spherical glass powder, boric acid and potassium silicate; the raw materials are ground and dispersed; after the radar detection coating is tested through an infrared spectrum tester and a reflectivity arch tester, the absorption rate can reach 85 to 95 percent, the heat reflectivity is greater than or equal to 85 percent and the wind sand abrasion resistanceis strong; the radar detection coating can resist the high temperature of 400 to 500 DEG C, the impact strength is 8 to 10N.m and the flexibility is 1 to 2mm; the wave absorption effect is good in amicrowave frequency range of 8 to 18GHz; sagging and after-tacking of the radar detection coating are not caused after 3 to 5d at 250 to 350 DEG C; and the rigidity is 0.7 to 0.9, the glossiness at 60DEG C is 95 to 97 percent and the adhesive force is 30 to 40MPa.

Description

technical field [0001] The invention relates to an anti-radar material, in particular to a preparation method of an aircraft anti-radar detection coating. Background technique [0002] With the development of science and technology, the application of stealth technology is becoming more and more extensive. Stealth technology is a special technology used in the design to reduce the radar, infrared, photoelectric, visual and other observation characteristics of the aircraft. The use of stealth technology is to prevent the aircraft from being detected by enemy detectors when it penetrates the defense, thereby enhancing the suddenness of the attack. To improve the survivability and combat effectiveness of the aircraft. Currently, the most challenging stealth technology is the development and application of stealth coatings. As the most convenient, economical and highly adaptable stealth technology, stealth paint has been widely used in aerospace and military equipment. In rec...
