description Belonging to the technical field of polymer processing, the invention discloses a polymer composite filling block, which is prepared from the following raw materials by weight: 50-60 parts of TPU, 25-30 parts of methyl vinyl silicone rubber, 4-5 parts of modified carbon nanotubes, 1 part of a coupling agent, 3-4 parts of hydrogen-containing silicone oil, and 0.001 part of a platinum catalyst. The invention further discloses a preparation method of the filling block. Through dynamic vulcanization, TPU, silicone rubber and other auxiliaries are mixed, so that the crosslinking density of a rubber polymer can be improved, the tensile strength of a rubber material can be improved, the tensile permanent deformation can be reduced, and the long-term use effect of an elastomer material is good; the self-made modified carbon nanotubes are doped into the rubber material, and after the carbon nanotubes are modified, the carbon nanotubes can be uniformly dispersed in a polymer matrix, the interface bonding force between
