Zusammenfassung:The invention relates to a wear-resistant and ozone-resistant railway damping rubber base plate as well as a preparation method and application thereof. The rubber base plate is prepared from the following raw materials in parts by weight: 70 to 80 parts of butadiene styrene rubber, 20 to 30 parts of butadiene rubber, 3 to 5 parts of zinc oxide, 2 to 4 parts of stearic acid, 1 to 2 parts of sulfur, 0.5 to 1 part of dispersing agent, 0.5 to 1.5 parts of coupling agent, 4 to 5 parts of vulcanization promoting component, 4 to 6 parts of anti-aging component and 70 to 85 parts of wear-resistant reinforcing component. The sum of the styrene-butadiene rubber and butadiene rubber is 100 parts; the anti-aging component is prepared from the following raw materials: protective wax, a p-phenylenediamine anti-aging agent and a ketoamine anti-aging agent in a weight ratio of (1-2): (1-3): (2-3); the wear-resistant reinforcing component is prepared from the following raw materials in parts by weight: 15-20 parts of carbon-
