Problems solved by technology

[0004] Even so, the wave-absorbing coatings in the prior art still cannot meet the needs of the rapid development of the aerospace industry, and continuous research and improvement of the wave-absorbing coatings are required to enable the wave-absorbing coatings to be used on the surfaces of aerospace vehicles and carriers. Only when the effect is greatly improved can the microwave characteristics of the aircraft surface be improved, and the accuracy and safety factor can be improved.

Abstract

The invention relates to the technical field of paint, especially to a wave-absorbing paint and a preparation method thereof. Specifically, two-component component A and component B are employed, subpackaging treatment is carried out on the component A and component B, then in the use process, the component A and component B are mixed evenly and applied to coating treatment, and by combining selection of the raw materials in the component A and raw material ratio design, organic silicon resin is effectively improved, and complicated microscopic biochemical action occurs between the organic silicon resin and acrylic resin, an electro-absorption agent, a magnetic absorption agent and assistants, thereby enhancing all the performance of the wave-absorbing paint. electrical performance index detection of the wave-absorbing paint shows that the isolation degree is 76-97dB, and the directional diagram is 189-221 degrees.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wave-absorbing coating and a preparation method thereof. Background technique [0002] With the continuous development of aerospace technology, the comprehensive performance of aerospace in terms of range and flight speed, hit accuracy, and defense penetration capabilities are all improving, which requires designers or operators to take into account the control of the characteristic signals of the transceiver antenna to Further improve the accuracy of the system; and aerospace carriers are generally made of light alloy castings, resulting in the production of wave-absorbing coatings on the outer surface of the alloy cabin that the designer or operator is waiting for can effectively solve the above technical problems. This allows designers or operators to take into account the reception of characteristic signals. [0003] With the continuous and rapid development of the aerosp...
