▎ 摘  要

NOVELTY - Wave-absorbing material comprises a first skin (1), wave-absorbing honeycomb core layer (4), second skin (5) and reflecting layer, where the surface of the wave-absorbing honeycomb core layer is provided with a coating. The raw material of the coating comprises resin, flame retardant, absorbent and solvent. USE - Wave-absorbing material. ADVANTAGE - The wave-absorbing material has broadband strong absorption effect, flame retardant and low smoke toxicity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a wave-absorbing material, involving: a. uniformly dispersing the resin and absorbent, flame retardant and solvent to prepare coating; b. using the coating to form a coating on the surface of the wave-absorbing honeycomb core layer and curing to obtain the functionalized wave-absorbing honeycomb core layer; and c. subjecting functional absorbing honeycomb core layer and coating prepreg sequence for paving in the mold according to the coating prepreg, hot pressing curing and forming, using adhesive bonding the lower surface of the second skin for reflecting layer to obtain product. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a wave-absorbing material. First skin (1) Surface layer absorbing honeycomb core (2) Bonding layer (3) Wave-absorbing honeycomb core layer (4) Second skin (5) Reflecting layer (6)
