The invention discloses a thermoplastic rubber modified material which is characterized by consisting of the following components in part by weight: 30 to 40 parts of styrene thermoplastic elastomer SBS (Styrene Butadiene Styrene), 5 to 10 parts of Vistamaxx propylene based elastomer, 4 to 50 parts of heavy calcium carbonate, 2 to 5 parts of nano graphite powder, 3 to 5 parts of black master batch, 7 to 10 parts of polypropylene chromatophore, 5 to 10 parts of white oil, 1.5 to 2.0 parts of titanate coupling agent, 0.1 to 1 part of nano cerium oxide and 1 to 3 parts of Chemlok adhesive. The thermoplastic rubber modified material provided by the invention changes performance of a thermoplastic rubber material which uses SBS as the main body, improves folding resistance, tensile strength of the material, abrasive resistance and aging resistance and also improves compounding intensity of compounding the rubber material and other materials and glossiness of a product.
