Magnesia carbon brick and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a magnesia carbon brick and a preparation method thereof. The refractory material comprises 55-110 parts of fusedmagnesite, 12-16 parts of graphite, 1-3 parts of a binding agent and 1-6 parts of an additive, wherein the binding agent is modified phenolic resin; through the design of the magnesia-carbon brick, the technical problem that the performance of the magnesia-carbon brick is reduced due to the fact that phenolic resin is used as a binding agent, the high temperature resistance is poor and the magnesia-carbon brick is easy to oxidize in the prior art is solved.
本发明涉及耐火材料技术领域，尤其是涉及一种镁碳砖及其制备方法；包括电熔镁砂55‑110份、石墨12‑16份、结合剂1‑3份和添加剂1‑6份；其中，结合剂为改性酚醛树脂；通过镁碳砖的设计以解决现有技术中存在的镁碳砖的使用酚醛树脂作为结合剂，耐高温性差及易氧化，导致镁碳砖性能下降的技术问题。
