Problems solved by technology

[0004] Patent CN104073085A discloses "anti-visible light and near-infrared detection fluorocarbon optical camouflage coating and its preparation method", but the coating only has visible light and near-infrared camouflage performance, and cannot satisfy the camouflage of mid-to-far infrared and radar waves
Patent CN106047119A discloses "a new type of heat-insulating hollow ceramic microsphere infrared camouflage coating material". This coating material has a good infrared stealth effect, but it cannot resist the detection of radar waves.
[0005] At present, domestically developed camouflage coatings are still in the exploratory stage in terms of compatibility against visible light, infrared and radar wave detection, and there are no reports on coating materials that can effectively solve the problem of anti-corrosion and effectively resist multiple detection methods

Abstract

The invention discloses a multi-spectral broadband anticorrosion stealth coating material. The coating sequentially comprises a camouflage painting coating layer, a graphene anticorrosion coating layer and a radar wave absorbing coating layer from the outside to the inside. The camouflage painting coating layer is a matt polyaspartate polyurea system containing a high-performance pigment, and hasvisible and near-infrared camouflage functions; the graphene anticorrosion coating layer is an epoxy zinc-rich / aluminum-rich system containing graphene, and has anticorrosion and infrared stealth functions; and the radar wave absorbing coating layer is an epoxy resin system containing a wave absorbing material, and has a broadband wave absorbing function. Materials of the camouflage painting coating layer, the graphene anticorrosion coating layer and the radar wave absorbing coating layer are respectively prepared by adding corresponding resins, assistants and pigment fillers at certain proportions according to a certain sequence proportion, and performing high-speed dispersion and grinding. The compatibility among the coating layers is good, and the multi-spectral broadband anticorrosionstealth coating material can be applied to camouflage stealth and corrosion protection in the fields of military vehicles, military devices, power stations, emitting devices and the like.

Description

technical field [0001] The invention relates to a multi-spectrum wide-band anti-corrosion stealth coating material, which belongs to the technical field of camouflage and stealth. Background technique [0002] Under the background of changing world situation and frequent conflicts in local areas, all countries attach great importance to the development and research of camouflage and stealth technology. On the modern battlefield, it is particularly important to improve the camouflage ability of one's own military facilities and reduce the probability of being detected and destroyed by the enemy. Camouflage coatings are widely used in tanks, ships, aircraft, military equipment and other important combat weapons and equipment because they are not limited by the shape of the base material, easy to construct, and moderate in cost. According to the function, camouflage coatings can be divided into: visible light-near infrared camouflage coatings, infrared camouflage coatings, rad...
