The invention provides automotive abrasion-resistant damping rubber and preparation method thereof. The preparation method comprises the following steps that 1, natural rubber and polybutadience rubber are added to a mixer for mixing; 2, the rubber material obtained in the step 1, high-abrasion-resistance carbon black N330, zinc oxide, stearic acid, N-isopropyl-N'-phenyl para-phenylenediamine, styrenated phenol, dibenzothiazyl disulfide, tetramethyl thiuram disulfide, polyether urethane modified epoxy resin, polyacrylate toughened and modified epoxy resin, nano silicon carbide, calcium sulfate whiskers and magnesium borate whiskers are added to the mixer for mixing; (3) sulfur is added to the rubber material in the step 2 for mixing again; 4, the rubber material obtained in the step 3 is vulcanized in a vacuumizing and vulcanizing machine. The automotive abrasion-resistant damping rubber has good elasticity, mechanical properties and abrasion-resistant properties.
