The invention relates to a magnesia-alumina spinel-graphene refractory material product and a preparation technology thereof. The preparation technology comprises the following steps: carrying out ball milling on expanded graphite, magnesia-alumina spinel fine powder, silicon powder and boric acid for 2-3 hours, then heating to 700 DEG C for heat treatment to obtain mixed fine powder pretreated by boron doped antioxidant graphene, silicon powder and magnesia-alumina spinel, sequentially adding magnesia-alumina spinel granules, alumina sol, pretreated fine powder and lithium fluoride into a mixing and grinding machine, strongly mixing and grinding to be uniform, molding, drying, and sintering, so that the magnesia-alumina spinel-graphene refractory material product is obtained. The refractory material product provided by the invention has high thermal shock resistance and high corrosion resistance, and the thermal shock resistance is more than 30 times of water quenching cycles at the temperature of 1100 DEG C.
