Abstract

The invention provides a powdery material special for weaponry. After aluminum powder is treated by a surface modifier of the powdery material special for the weaponry, a layer of protective film is formed on the surface of the treated aluminum powder, so that oxidation resistance of the aluminum powder is improved, and an oxidation process of the aluminum powder in use can be delayed. The powdery material for the weaponry has the advantages that an infrared stealthy coating prepared from the powdery material is low in infrared emissivity and excellent in aging resistance, an aging process of the infrared stealthy coating slows down, service life of the coating is prolonged, and infrared emissivity increase is slow during thermal aging testing.

Description

technical field [0001] The invention relates to a powder material, in particular to a special special powder material for weapon equipment. Background technique [0002] With the development of infrared detection and image processing technology, the threat of infrared reconnaissance and infrared guided attack system to the attacked target is becoming more and more serious. In order to improve the survivability of the target and ensure the combat effectiveness, the status of infrared stealth technology in the modern defense system is also increasingly prominent. [0003] Infrared stealth materials mainly refer to functional materials used to weaken the infrared characteristic signal of the target weapon system so as to meet the requirements of infrared stealth technology. The development of infrared stealth materials is the key to the development of infrared stealth technology. Coating-type infrared stealth materials are easy to construct, simple in process, low in cost, dur...
