Abstract

The invention discloses a high temperature resistant coating for a missile shell and a preparation method of the high temperature resistant coating. The high temperature resistant coating is preparedfrom the following raw materials: epoxy resin, silicon dioxide, lead sulfide, carbon black, biuret polyisocyanate, phosphoric acid, phenylphosphonic acid, ethyl acrylate , nitrate, silicon carbide, xylene, selenium sulfide, zinc antimony white, micro silicon powder, kaolin and titanium oxide; the product adhesion level is 1; in a damp heat test for 20 to 30 d, the product is not sticky and has nofoam, and the salt spray corrosion resistance is not changed within 30 to 70 d; the hemispherical thermal emissivity En is equal to 0.5, and the fineness is 20 to 40 [mu]m; the product is rain-resistant and high in wear resistance, cannot fall off at a high temperature of 1,000 to 1,400 DEG C, cannot crack, swell and fall off after being soaked in trichloroethane, hydrochloric acid, sodium hydroxide and sodium chloride for 4 to 8 months, and has no changes after being boiled with water for 30 to 50 min.

Description

technical field [0001] The invention relates to the technical field of aviation coatings, in particular to a high-temperature-resistant coating for missile shells and a preparation method thereof. Background technique [0002] In the process of aviation manufacturing development, the replacement of materials presents a high-speed change, and materials and aircraft have been constantly developing under the mutual promotion. "One generation of materials, one generation of aircraft" is a true portrayal of the history of world aviation development. [0003] Aerospace coatings are coatings used on aircraft or missiles. According to the parts used, it can be divided into: missile skin coatings, aircraft cabin coatings, aircraft engine coatings, missile parts coatings, special special coatings, including heat insulation coatings, fireproof coatings and temperature display coatings. [0004] Taking missile surface and fuselage coatings as an example, the topcoat is generally epoxy...
