The present invention relates to a stress-buffering refractory material that is used for dry quenching coke equipment, and belongs to the refractory material. The stress-buffering refractory material is prepared by mixing stress-buffering raw materials, waste kiln, sintered or electrically molten mullite, micro Al2O3 powder, clay and dextrin water; wherein, the stress-buffering raw materials is molded through extrusion after andalusite, fused silica, the micro Al2O3 powder and the clay are mixed well, and is prepared after high-temperature sintering at temperature between 1400 DEG C and 1650 DEG C; the refractory material can buffer the stress produced by sudden cooling and sudden heating when in use; the thermal shock stability, high-temperature rupture strength, wear resistance and service life are greatly improved. Compared with the existing refractory material that is used for the dry quenching coke equipment, the thermal shock resistance is improved by 20 to 40 percent; the mechanical properties are improved by 10 to 20 percent; the erosion resistance is improved by 30 to 50 percent; the wear resistance is improved by 15 to 35 percent and the service life is improved by more than 50 percent.
