COMPOSITION FOR RADIO WAVE ABSORBER, RADIO WAVE ABSORBER, AND MANUFACTURING METHOD OF RADIO WAVE ABSORBER |
摘要 |
PROBLEM TO BE SOLVED: To provide a composition for absorbing radio wave absorber suitable for absorbing radio waves in the vicinity of 1 GHz and in the higher GHz bands which can reduce the weight and thickness, to provide the radio wave absorber produced by molding that composition, and to provide a manufacturing method of the radio wave absorber. SOLUTION: The composition for radio wave absorber contains 100-500 mass parts of aluminum powder having an oxide film on the surface, and 50-200 mass parts of carbon black for 100 mass parts of ethylene propylene rubber wherein the mean particle diameter D<SB>50</SB>of the aluminum powder is 10-35μm, and a radio wave absorber is obtained by molding the composition for radio wave absorber into sheet shape.
