Problems solved by technology

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides the preparation and method of novel stealth coating material, the technical problem to be solved by the present invention is: in the field of military stealth, low emissivity materials especially low emissivity Coatings are the focus of research. This type of coating mainly uses low-emissivity materials such as aluminum powder and brass powder as infrared absorbers. Due to the poor tolerance of the coating to pollution, dust and moisture can significantly increase the emissivity, and In the process of spraying, it is difficult to form a strong bond between the body and the particles, which makes it difficult to control the thickness and adhesion effect of the coating, which affects its actual stealth and use effect.

Abstract

The invention discloses preparation and method of a novel stealth coating layer material, and particularly relates to the technical field of stealth materials. According to the invention, by using the mixed spraying effect of a transmission hot-pressing method and thermal spraying, a glass or ceramic-based wave-absorbing coating layer with high bonding strength and good thermal stress resistance can be prepared on a metal surface through the traditional hot-pressing method, however, the traditional hot-pressing method can only be applied to flat metal, and the thermal spraying can utilize a heat source to heat ceramic particles to a molten or semi-molten state while flame or high-speed gas is utilized to spray the ceramic particles to the surface of the metal to form a coating layer in a deposition mode; and the ceramic particles have high kinetic energy and heat energy in the spraying process so as to achieve the controllable thickness of a relatively strong bonding layer between the coating layer and the matrix or particles, and the spraying is slightly limited by the shape of a component, and is suitable for preparing the high-temperature wave-absorbing coating layer, so that the coating layer processing and spraying effects of the preparation method are guaranteed, and the actual use effect of the coating layer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of stealth materials, more specifically, the invention relates to the preparation and method of a new stealth coating material. Background technique [0002] The propagation of infrared radiation in the atmosphere follows the laws of refraction, reflection, absorption, and scattering of visible light. It has the general physical characteristics of light. Its transmission ability in the atmosphere is related to the content of water and carbon dioxide in the atmosphere. Objects emit infrared radiation At the same time, the water and carbon dioxide in the atmosphere have to absorb the radiation of a certain band, and attenuate the infrared radiation signal of this band, especially the moving targets, such as aircraft, tanks, warships and missile loading vehicles, etc., all have high-power power sources, Intense thermal infrared radiation will be produced during movement. For some high-speed moving targets, such...
