Novel low-heat-conductivity GN30 insulating brick and preparation method thereof
The invention relates to the technical field of refractory bricks, and discloses a novel low-heat-conductivity GN30 heat-insulating brick and a preparation method thereof.The heat-insulating brick is prepared from, by weight, 10-25% of aluminum oxide hollow balls, 10-25% of emery powder, 5-10% of aluminum oxide micro powder, 5-10% of silicon oxide micro powder, 5-15% of sillimanite, 10-25% of clay powder, 1-5% of silicon-aluminum gel powder and 5-15% of additives. The silicon-aluminum gel powder and the additive are used as a brick body coagulant to improve the bonding property of the brick body, the aluminum oxide hollow spheres are used as brick body lightweight aggregate, the emery powder is used as brick body inert filler to achieve the effects of ensuring high temperature resistance, reducing density and achieving high strength, and meanwhile the sillimanite is used as a brick body expanding agent to improve the strength of the brick body. And then the aluminum oxide micro powder, the silicon oxide micro powder and the clay powder are used as brick body binding agents, so that the effects of reducing the sintering temperature, forming a mullite binding phase and improving the high-temperature resistance and the thermal shock resistance of the refractory material are achieved.
本发明涉及耐火砖技术领域，公开了一种新型低导热GN30隔热砖及其制备方法，所述隔热砖由如下原料制备，其按照重量比分包括：氧化铝空心球10‑25wt%、刚玉粉10‑25wt%、氧化铝微粉5‑10t%、氧化硅微粉5‑10wt%、硅线石5‑15t%、黏土粉10‑25wt%、硅铝凝胶粉1‑5wt%以及添加剂5‑15wt%。本发明通过利用硅铝凝胶粉、添加剂作为砖体凝结剂，提高砖体结合性，通过利用氧化铝空心球作为砖体轻骨料，刚玉粉作为砖体惰性填料，起到保证耐高温性能、降低密度、高强度的作用，同时通过利用硅线石作为砖体膨胀剂，起到减小烧成收缩和提高抗热震性的作用，继而利用氧化铝微粉、氧化硅微粉和黏土粉作为砖体结合剂，起到降低烧结温度、形成莫来石结合相、提高耐火材料耐高温和抗热震性能的作用。
