NOVELTY - High-thermal-conductivity silica gel wave-absorbing sheet comprises resin, magnetic powder, heat conduction filler and additive. USE - As high-thermal-conductivity silica gel wave-absorbing sheet. ADVANTAGE - The wave-absorbing sheet solves the technical problems of complex structure and insufficient heat dissipation performance of existing wave absorbing material, improves the heat dissipation performance, effectively absorbs electromagnetic waves, and is prepared by simple process and easy to process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the wave-absorbing sheet, involving (a) taking above-mentioned raw materials, uniformly mixing at 2-5 degrees C under vacuum conditions, adding catalyst and solvent, and uniformly mixing to obtain slurry, and (b) coating obtained slurry with slurry, where the thickness of coating is 0.15-3 mm, and drying to obtain wave-absorbing sheet.
