▎ 摘 要
NOVELTY - Absorbing material comprises 70-85 wt.% silica gel, 3-10 wt.% graphite, 1-5 wt.% graphene, 0.1-6 wt.% carbon fiber, 0.1-5 wt.% nanocarbon, 1-3 wt.% ferrite, 0.1-3 wt.% metal oxide and 0.1-2 wt.% solvent. USE - As absorbing material. ADVANTAGE - The absorbing material has wide protection frequency band, strong electromagnetic wave absorption effect, and prevents radiation while not blocking and affecting normal communication signals of electronic equipment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the absorbing material, involving (i) mixing the above-mentioned raw materials at room temperature, (ii) baking and filtering the mixed material, pulverizing and stirring, and (iii) dissolving the mixed material in the extruder at a high temperature, carrying out extrusion injection molding to form a sheet shape, cooling and demolding.
