Heat-insulating refractory brick and preparation method thereof
The invention relates to the technical field of refractory brick preparation, in particular to a heat-insulating refractory brick and a preparation method thereof.The heat-insulating refractory brick is prepared from, by weight, 8-15 parts of high-quality clay, 15-25 parts of high-precision microbeads, 5-12 parts of siliceous micro powder, 15-20 parts of perforated perlite and 10-20 parts of aluminum-silicon-calcium powder; the heat-insulating refractory brick with high energy-saving performance, ultrahigh-strength heat-insulating performance and high refractoriness can be obtained through the four steps of burdening, mixing and stirring, compression molding and sintering of the components, and the strength of the heat-insulating refractory brick can reach 10-13 MPa and is 3 times higher than that of the national standard NG130-1. 0; the heat conductivity coefficient is only about 0.2 and is one time lower than that of the national standard 0.4, the energy-saving effect is remarkable when the heat-insulating brick is used in various kiln heat-insulating layers, energy is saved by about 30% compared with similar products in the market, the cost is reduced by 30-50%, and the heat-insulating brick has good economic benefits.
本发明涉及耐火砖制备技术领域,具体地,涉及一种隔热耐火砖及其制备方法,由以下重量百分比的各组分组成:优质黏土8‑15份,高精微珠15‑25份,硅质微粉5‑12份,开孔珍珠岩15‑20份,铝硅钙粉10‑20份;钒土熟粉12‑18份,将上述组分经配料、混合搅拌、压制成型和烧成四个步骤进行制备,即可得到具有高节能和超高强隔热性能,且耐火度高的隔热耐火砖,本发明制成的隔热耐火砖强度可达到10‑13MPa,比国标NG130‑1.0强度高出3倍;导热系数只有0.2左右,比国标0.4低1倍,在多种窑炉保温层使用,节能效果显著,比市场同类产品多节能30%左右,成本低30‑50%,有较好的经济效益。
