Magnesium-calcium-carbon refractory material and preparation method thereof
The invention relates to a magnesium-calcium-carbon refractory material and a preparation method thereof. The refractory material comprises 100-120 parts of magnesia-calcia clinker particles, 40-50 parts of magnesia-calcia clinker fine powder, 15-35 parts of nano-magnesia, 20-30 parts of nano-calcia, 20-35 parts of zirconia, 10-20 parts of graphene, 5-10 parts of an additive, 7-12 parts of a binder and 5-12 parts of nano-carbon fibers. The inside of the refractory material prepared in the invention is compact, so the bulk density is improved, and the apparent porosity of the refractory material is reduced to prevent expansion, thereby all physical performances, such as the strength, the thermal shock resistance and the thermal impact resistance of the refractory material are further improved; and the preparation method has the advantages of simplicity, abundant raw materials, and suitableness for factory production.
