The invention relates to a damping material, in particular to a silicone-rubber damping composite material for an automobile and belongs to the technical field of automobile damping materials. The silicone-rubber damping composite material for the automobile is prepared from, by weight, 100 parts of methyl vinyl phenyl polysiloxane rubber, 1-10 parts of gamma-aminopropyl triethoxysilane, 2-4 partsof tetrapropyl orthosilicate, 1-6 parts of ceramicpowder, 2-4 parts of white carbon black, 1-6 parts of graphene, 5-10 parts of kaolin, 1-2 parts of dibutyltin dilaurate, 1-4 parts of hydroxyl silicone oil, 2-7 parts of ultrafine polytetrafluoroethylene powder and 3-8 parts of amino modified carbon nano tube material. The prepared material can effectively absorb energy and has the effects of shock proofing, impact buffering, thermal insulation, sound insulation and the like.
