High-strength environment-friendly refractory brick and preparation method thereof
The invention relates to a high-strength environment-friendly refractory brick, which is mainly prepared from the following components in parts by mass: 20 to 25 parts of flint clay, 20 to 25 parts of alumina, 10 to 15 parts of andalusite, 5 to 10 parts of clay, 10 to 15 parts of silicon sulfide, 2 to 5 parts of monatomic silicon, 2 to 5 parts of active alpha-Al2O3 micro powder, 1 to 3 parts of an adhesive and 1 to 3 parts of a pore-forming agent. The adhesive is one of an aluminum dihydrogen phosphate solution and polyvinyl alcohol, and the pore-forming agent is sawdust impregnated with sol. According to the high-strength environment-friendly refractory brick and the preparation method thereof, the formula setting is reasonable, the refractory brick has excellent fire resistance, meanwhile, the alkali gas phase erosion resistance and the overall strength of the refractory brick are improved, the preparation process is simple, large-scale production is easy, energy is saved, environment friendliness is achieved, and the application prospect is wide.
一种高强度的环保型耐火砖及其制备方法，所述耐火砖，按质量份数计，主要由以下组分构成：焦宝石20‑25份、矾土20‑25份、红柱石10‑15份、粘土5‑10份、硫化硅10‑15份、单质硅2‑5份、活性α‑Al2O3微粉2‑5份、粘合剂1‑3份、造孔剂1‑3份；所述粘合剂为磷酸二氢铝溶液、聚乙烯醇中的一种，所述造孔剂为被溶胶浸渍后的锯末。本发明所述的高强度的环保型耐火砖及其制备方法，配方设置合理，在具有优异的耐火性的同时，提高耐火砖的抗碱气相侵蚀能力以及整体强度，制备工艺简单，易于大规模生产，节能环保，应用前景广泛。
