Abstract

The invention belongs to the field of absorbing material research, and particularly relates to a method for preparing stealthy fabric with double functions of radar stealth and infrared stealth. According to the method, the binding strength of a radar stealth layer and textile is improved by using electrostatic interaction between plasma grafting-introduced carboxyl and polyaniline absorbing materials and the surface etching effect of low-temperature plasma; the binding strength of the radar and the infrared stealth layers and the textile is improved by using the reactivity between a binary aldehyde crosslinking agent and amino on a polyaniline polymer and a microcapsule wall material and a polyurethane adhesive; the obtained stealth coating is not only good in binding strength with the textile, but also light in quality and good in durability, and has multi-band stealth effects of radar, infrared light and visible light.

Description

technical field [0001] The invention belongs to the research field of wave-absorbing materials, and in particular relates to a preparation method of a stealth fabric with dual functions of infrared stealth and radar stealth. Background technique [0002] In recent years, with the advent of various advanced detection technologies and precision-guided weapons, the threats to military targets, weapons and combat soldiers on the battlefield have become increasingly serious. Stealth technology, as an important means to improve the survivability of weapons and equipment in war, has been paid more and more attention by countries all over the world. [0003] According to different detection technologies, stealth technology can be divided into: radar stealth, infrared stealth, laser stealth, acoustic stealth and visible light stealth, etc. At present, in military detection, radar detection accounts for about 60%, infrared detection accounts for 30%, and other 10%. Therefore, the cu...
