▎ 摘　　要

NOVELTY - Wave-absorbing film comprises a wave-absorbing adhesive film comprising a reinforcing layer (2) or an adhesive film layer (3), a wave-absorbing layer (1) and a backing (4), where the wave-absorbing layer and the backing are respectively arranged on the outermost side of the wave-absorbing film. The wave-absorbing layer is a film formed by mixing a wave-absorbing material with a resin matrix. USE - Wave-absorbing film. ADVANTAGE - The film has enhanced adhesive properties and improved work efficiency, avoids cracking of cast wave absorbing film during laying, saves time for compounding two before construction, reduces difficulty of operation and number of processes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the wave-absorbing adhesive film. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the absorbing film. Wave-absorbing layer (1) Reinforcing layer (2) Adhesive film layer (3) Backing (4)
