Wave-absorbing paint and preparation method thereof

The invention relates to a wave-absorbing paint. According to the invention, two absorbents in a coating can be uniformly distributed in equal proportion in the paint and the final coating through an absorbent formed by connection of carbonyl iron powder coated with acrylic resin and wave-absorbing alloy powder coated with isocyanate group resin; and furthermore, on one hand, the absorbent is uniformly and stably distributed in the coating, and the wave-absorbing bandwidth and the wave-absorbing strength of the coating are relatively high. Compared with the prior art, the paint has better impact performance and flexibility, is not prone to local fracture, is not prone to corrosion, and has better coating surface flatness. Therefore, the paint can achieve a broadband high-strength wave-absorbing effect, and the wave-absorbing effect of each area is the same and stable; and the paint has good mechanical properties and corrosion resistance. 本发明涉及一种吸波涂料，通过包覆有丙烯酸树脂的羰基铁粉和包覆有异氰酸酯基团树脂的吸波合金粉相连接的吸收剂，在涂层中能够达到两种吸收剂在涂料和最终
