NOVELTY - Flexible wave-absorbing material comprises 61-83 wt.% polyurethane sponge, 10-32 wt.% oxidized graphene, and 6-26 wt.% absorbing agent. USE - Flexible wave-absorbing material for a suction tip cone (claimed). ADVANTAGE - The flexible wave-absorbing material has excellent mechanical strength and flexibility, thus ensuring the flexibility and strength of the absorbing sponge material, and improving the environment-adaptive capacity of the sponge material. The very thin layer of oxidation can graphene firm bonding ensures the low density of the absorber material finished product. The polyurethane sponge material is easy to remove powder. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for preparing wave-absorbing material, which involves: a. mixing the material comprising an oxidized graphene adhesive with water to obtain an oxidized graphene adhesive dispersion, b. mixing the material containing the wave absorbing agent dispersion liquid with the adhesive dispersion liquid to obtain the dipping liquid, the polyurethane sponge into the dipping liquid dry to obtain the flexible wave-absorbing material; 2. a wave absorbing pointed cone, which comprises
