Anti-oxidation refractory material and preparation method thereof
The invention relates to an anti-oxidation refractory material and a preparation method thereof. The anti-oxidation refractory material is prepared through adding an auxiliary additive, graphene, a binder and nano-alumina to a main raw material magnesium aluminate spinel with different particle sizes. The above product has a uniform microstructure, so the strength and the thermal shock resistance of the product are improved; nanometer zinc oxide has fine granularity and can be used to fill fine pores, so the porosity of the product is reduced, and the bulk density is improved; and the anti-oxidation refractory material also has the advantages of high refractoriness, good anti-oxidation performance, excellent erosion resistance, good thermal shock resistance and wide sintering temperature range.
