The invention discloses a sealing ring material and a preparation method thereof, and belongs to the technical field of sealing ring production, the sealing ring material comprises the following components: 50-80 parts of ethylene propylene diene monomer; 5 to 10 parts of polyurethane rubber; 5-10 parts of fluororubber; 10-20 parts of hydrogenated nitrile rubber; 5-8 parts of silicone rubber; 0.5-3 parts of a reinforcing material; 1-3 parts of a nano filler; 0.5 to 1 part of an antioxidant; and 0.5-1 part of microcrystalline cellulose. According to the sealing ring material and the preparation method thereof, through the arrangement of the reinforcing fibers, the reinforcing and toughening effects can be achieved after a sealing ring is produced, the tensile strength, the bending strength, the impact toughness and other mechanical properties of the sealing ring can be improved, and therefore the service life of the sealing ring is prolonged, and the reliability of the sealing ring is improved; the hardness an
