Unfired alumina-magnesia carbon brick and preparation method thereof
The invention provides an unfired alumina-magnesia carbon brick and a preparation method thereof. The unfired alumina-magnesia carbon brick is prepared from the following components in parts by weight: 40-70 parts of brown fused alumina, 5-12 parts of fused magnesia, 4-7 parts of graphene oxide, 1-3 parts of metal aluminum powder, 0.5-2 parts of nanoscale vanadium pentoxide, 0.5-1 part of active lime and 2-4 parts of phenolic resin. The unfired alumina-magnesia carbon brick provided by the invention is low in porosity, high in volume density, high in normal-temperature compressive strength and high in thermal shock resistance.
本发明提供了一种不烧铝镁碳砖及其制备方法，由以下重量份的组分制成：40‑70份棕刚玉，5‑12份电熔镁砂，4‑7份氧化石墨烯，1‑3份金属铝粉，0.5‑2份纳米级五氧化二钒，0.5‑1份活性石灰，以及2‑4份酚醛树脂。本发明提供的不烧铝镁碳砖气孔率低，体积密度高，常温耐压强度高、热震稳定性高。
