The invention discloses a trans-butadiene-isoprene rubber material with a high crystallization melting temperature and a preparation method of the trans-butadiene-isoprene rubber material. The trans-butadiene-isoprene rubber material is prepared from the following components in parts by weight: 100 parts of butadiene-isoprene copolymer, 0-50 parts of filler, 0.1-4 parts of anti-aging agent, 0.1-4 parts of chelating agent and 0.1-6 parts of other auxiliaries. Wherein the butadiene-isoprene copolymer contains a long trans-1, 4-polybutadiene long chain segment, the content of a trans-1, 4-structure of the butadiene-isoprene copolymer is greater than 85%, the crystallization melting temperature is 120-145 DEG C, and the crystallization melting enthalpy is 1-30 J/g. According to the trans-butadiene-isoprene rubber material, a high-temperature-resistant and easy-to-crystallize copolymer is obtained by adopting a constant-ratio copolymerization method of butadiene and isoprene, and then a chelating agent, an anti-aging agent, a filler and other auxiliaries are added, so that the trans-butadiene-isoprene rubber material is obtained. The material is applied to tread rubber and sidewall rubber of tires and rubber vibration reduction products, and the heat resistance and the dynamic fatigue life of the products are remarkably improved; and the material can also be used as a phase change energy storage material to be applied to building insulation layers, equipment insulation layers and sealing insulation fields.
