Abstract

The invention discloses a graphene containing infrared radar compatible stealth coating and a preparation method thereof. The graphene containing infrared radar compatible stealth coating comprises aresin system formed by mixing of resin, a solvent and an assistant, aluminum powder with conductivity and a radar wave reflection absorbent are dispersed in the resin system, and the radar wave reflection absorbent is composed of graphene with high dielectric constant and a magnetic absorbent. The dielectric properties of graphene are combined with electromagnetic properties of the magnetic absorbent to improve the reflection and absorption properties of the coating from two aspects of dielectric loss and electromagnetic loss, so as to achieve the effect of radar stealth' in addition, the graphene for radar absorption is dispersed among aluminum slurry particles in the resin system, the aluminum slurry particles are connected by the lamellar structure of the resin system to improve the conductivity of the coating, and low infrared emissivity is achieved; the coating can be used in high temperature radiation and radar bright spots of ships and warships, and can also be extended to ground equipment with high temperature position and radar stealth demand.

Description

technical field

[0001] The invention relates to a special functional stealth paint, in particular to a graphene-containing infrared radar compatible stealth paint and a preparation method thereof. Background technique

[0002] The United States is the first country to carry out research on infrared stealth coatings, and its research and development of infrared stealth coatings has achieved great success. The formula design of stealth paint has put forward some important conclusions, and the research on thermal stealth paint has been carried out in the United States since the early 1970s. In the mid-1970s, as the performance of infrared detectors continued to improve, the U.S. Army accelerated the development of thermal stealth coatings. In the early 1980s, the United States developed a low-emissivity coating that is resistant to thermal surveillance, and used a conductive coating to combine the stealth effects of thermal infrared and radar. The United States proposed to de...
