Abstract

The invention belongs to the technical field of coatings, and particularly relates to a light salt-spray-resistant wave-absorbing coating and a preparation method thereof. The radar wave-absorbing layer, the reflection conversion layer and the radar wave-absorbing layer are arranged from inside to outside; the radar wave-absorbing layer comprises a wave-absorbing filler, an auxiliary agent and resin; and the reflection conversion layer comprises a microporous filler, an auxiliary agent and resin. The wave-absorbing coating is few in operation steps and high in feasibility, conforms to the development direction of "thinness, lightness, width and strength" of the wave-absorbing coating, can be used for radar stealth of various ground equipment, and can also be popularized and applied to various aircrafts.

Description

Technical field: [0001] The invention belongs to the technical field of coatings, and in particular relates to a light-weight salt spray resistant wave-absorbing coating and a preparation method thereof. Background technique: [0002] Stealth technology mainly involves two aspects of material stealth and structural stealth. The former is to use wave-absorbing materials or coatings to achieve stealth; the latter is to rationally design equipment structure, shape and other factors to improve concealment, but at present, part of the performance of weapons and equipment must be sacrificed. Compared with it, the stealth coating shows greater advantages due to its convenient use, low cost, convenient operation, and not being limited by the geometric shape of the parts, and has become the fastest-growing stealth technology research field in recent years. This technology uses a layer of special material coated on the surface of the weapon equipment, which can absorb the electromagn...
