Refractory material and preparation method therefor
The invention relates to a refractory material and a preparation method therefor. The refractory material consists of the following raw materials in parts by mass: 100-120 parts of aluminium oxide particles, 25-35 parts of alpha-aluminium oxide powder, 15-20 parts of nano aluminium oxide, 20-35 parts of zirconium oxide, 10-20 parts of graphene, 5-10 parts of an additive, 7-12 parts of a binding agent and 5-12 parts of nano magnesium oxide. The refractory material disclosed by the invention is internally compact; volume density of the refractory material is improved, and apparent porosity of the refractory material is reduced to prevent expansion, so that various physical performances such as strength, thermal shock resistance, and thermal impact resistance of the refractory material are further improved. The preparation method is simple and suitable for industrial production; and raw materials are rich.
