The invention discloses high-temperature-resistant abrasion-resistant macromolecule shock-absorption rubber for vehicles, a preparation method of the high-temperature-resistant abrasion-resistant macromolecule shock-absorption rubber, and a preparation method of an automobile exhaust pipe lug. The preparation method of the high-temperature-resistant abrasion-resistant macromolecule shock-absorption rubber comprises the following steps of conveying the following components in parts by mass of 60-70 parts of ethylene propylene diene monomer and 30-40 parts of silica gel into a banbury mixer, andperforming stirring and mixing; then adding 5-20 parts of zinc oxide, 1-3 parts of stearic acid, 0.1-0.5 part of essence, 3-8 parts of an abrasion-resistant agent, 1-4 parts of microcrystalline wax,0.2-1 part of an antioxidant, 2-4 parts of a common flow dispersing agent and 1-5 parts of Coumarone-indene resin, and then performing plastication for 50-70s; and then adding 30-50 parts of carbon black N550, 20-60 parts of carbon black N330 and 2-5 parts of paraffin oil, performing banbury warming, rubber discharging, roll mixing and cooling, then pouring milled glue into a banbury mixer, performing mixed warming, then adding 1-3 parts of insoluble sulfur, 1-5 parts of a vulcanizing agent and 1-3 parts of an accelerant, performing warming milling, and then performing rubber discharging and roll mixing once again. The obtained shock-absorption rubber and a metallic framework are subjected to vulcanization and shaping in a mold, so that the automobile exhaust pipe lug is prepared.
