The invention relates to the technical field of amorphous refractory materials, and provides an environment-friendly tundish dry material and a preparation method thereof. The environment-friendly tundish dry material is prepared from the following components in parts by mass: 45 to 55 parts of fused magnesite, 40 to 50 parts of sintered magnesite, 3 to 4 parts of a sintering agent, 3 to 6 parts of an organic binding agent and 1 to 3 parts of 4, 4 '-bis (2, 3-epoxy propoxy) biphenyl, the preparation method of the environment-friendly tundish dry material comprises the step of uniformly mixing the components in parts by mass to obtain the environment-friendly tundish dry material. Through the technical scheme, the problem of low strength of the organic environment-friendly binding agent in the prior art is solved. 本发明涉及不定型用耐火材料技术领域，提出了一种环保型中间包干式料及其制备方法。所述一种环保型中间包干式料，包括以下质量份的组分：电熔镁砂45~55份、烧结镁砂40~50份、烧结剂3~4份、有机结合剂3~6份、4,4'-双(2,3-环氧基丙氧基)联苯1~3份；所述一种环保型中间包干式料的制备方法，将所述质量份的组分混合均匀，得到环保型中间包干式料。通过上述技术方案，解决了现有技术中的有机环保结合剂
