The invention discloses a decorative material comprising the following components in parts by weight: 10-80 parts of polypropylene, 0-25 parts of partially-crosslinked vulcanized rubber, 0-25 parts ofTPO, 0-70 parts of polyethylene and 0.1-4 parts of compound with polyfunctional groups. The components of the decorative material are simple, the crosslinking degree among the components is good, andafter the decorative material is subjected to secondary high-temperature molding, embosses on the surface of the decorative material can be clearly seen, and the retention degree is good; and meanwhile, the decorative material has relatively high tensile strength, tearing strength, wear resistance as well as acid and alkaline resistance and good physical and chemical properties. The invention further discloses a preparation method of the decorative material, and the preparation method requires few steps and simple process, the operation is safe and the cost is low.
