Refractory material and preparation method thereof

The invention relates to the technical field of refractory materials, and discloses a refractory material and a preparation method thereof.The refractory material comprises the following raw materials: a refractory filler, an expansion filler, a composite flame-retardant filler, a modifier, vinyl phenyl silicone oil, hydroxyl silicone oil, a functional adhesive and a reinforcing filler. The composite flame-retardant filler and the functional adhesive are prepared to participate in the preparation process of the refractory material, so that the prepared refractory material has dual flame-retardant capability, high fire resistance and fire prevention capability and high cohesion, and can effectively avoid fire spreading and protect life and property safety in actual use; and moreover, the phenomena of pulverization, cracking and falling are not easy to occur, the sealing performance is good, contents are not easy to leak, an excellent protection effect on equipment is achieved, the maintenance cost of the equip
