The invention discloses a rubber bridge support material. The rubber bridge support material is prepared from CPE rubber, natural rubber, terpene phenolic resin, TM-80, light magnesium oxide, carbon black, HFR-3000, DOP, barium stearate, zinc oxide, stearic acid, paraffin, hindered phenol, DCP, a silane coupling agent KH-570 and sulphur. The preparation method of the rubber bridge support material includes the steps that all the components are weighed; HFR-3000 is modified; CPE rubber is plastified, modified HFR-3000, light magnesium oxide, barium stearate and paraffin are added, even mixing is carried out, and CPE mixing masterbatch is obtained; natural rubber is plasticated, terpene phenolic resin, zinc oxide, stearic acid and TM-80 are added, even mixing is carried out, CPE mixing masterbatch is added for joint mixing, hindered phenol, carbon black and DOP are added, mixing is carried out at a high temperature, and a rubber material is obtained; DCP and sulphur are added into the rubber material, mixing is carried out, and the rubber bridge support material is obtained. According to the rubber bridge support material, on the premise of guaranteeing good physical and mechanical properties of the prepared material, the good characteristics of low cost, high wear resistance, ozone resistance, weather aging resistance, high damping and the like are achieved; the preparation method of the rubber bridge support material is simple, good in operability and suitable for industrial production, application and popularization.
