▎ 摘　　要

NOVELTY - Wave-absorbing material comprises a surface layer and a bottom layer. The surface layer is an impedance matching layer and the bottom layer is a light absorbing layer. USE - The material is useful in building including residential building, commercial building, office building and an industrial building. ADVANTAGE - The wave-absorbing material has low volume weight, adjustable density and double-layer structure, high wave absorbing effect, effective absorption band width, low cost, heat-proof and non-combustible. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1 a preparation method of cement-based foam absorbing material; and 2 a wave absorbing plate.
