Explosion-proof broadband wave absorption composite material and preparation method thereof

The invention provides an explosion-proof broadband wave absorption composite material and a preparation method thereof, and belongs to the technical field of multifunctional materials. The preparation method of the explosion-proof broadband wave absorption composite material comprises the following steps: preparing explosion-proof skin by utilizing quartz fiber and unsaturated resin, preparing anelectrical loss wave absorption piece, preparing a magnetic loss wave absorption piece, preparing a broadband interlayer wave absorption material, and sequentially adhering the broadband interlayer wave absorption material and the explosion-proof skin to a reflecting base plate. The explosion-proof broadband wave absorption composite material prepared by the invention is of a laminated structure,and comprises the reflecting base plate, the broadband interlayer wave absorption material and the explosion-proof skin which are in contact in sequence. According to the preparation method providedby the invention, the technical obstacle that a wave absorption material and an explosion-proof material are difficult in combination is overcome, and the preparation method is simple and is easy in industrial implementation; the prepared explosion-proof broadband wave absorption composite material simultaneously has an explosion-proof function and a broadband wave absorption function and has thecharacteristics of good low-frequency performance, broad absorption band, low surface density and excellent environment performance, the explosion-proof function of a product is solved, and the broadband wave absorption function is also integrated.
