The invention discloses a preparation method of a wear-resistant SBS (styrene butadiene styrene) sole material. The preparation method comprises the following steps: step 1, calcium carbonate, maleic anhydride, ethylene glycol and water are mixed, and modified calcium carbonate is obtained; step 2, modified calcium carbonate, neodymium oxide, strontium carbonate, alumina, magnesium oxide and absolute ethyl alcohol are mixed uniformly and sintered, and a first mixture is obtained; step 3, polyethylene glycol is added to the first mixture, the materials are sintered, and a second mixture is obtained; step 4, ethylene glycol, water, linoleic acid, sodium dodecylbenzenesulphonate, styrene and potassium sulfate are added to the second mixture for a reaction, and a third mixture is obtained; step 5, SBS, the third mixture, polystyrene, UHMWPE (ultrahigh molecular weight polyethylene), carbon black, terpene resin, lanthanum oxide, cerium oxide, zirconia, PEEK (polyether-ether-ketone) resin, oxidized polyethylene wax, macadimia nut shell powder, snail shell powder and bamboo fibers are uniformly mixed and subjected to milling, and the wear-resistant SBS sole material is obtained. The SBS sole material has the advantages of high strength and good wear resistance.
