Low-thermal-conductivity multi-layer composite magnesium hercynite brick and preparation method thereof
The invention relates to the technical field of preparation of spar bricks, and discloses a low-thermal-conductivity multilayer composite magnesium-hercynite brick which comprises a plurality of layers of materials, each layer is composed of a low-thermal-conductivity magnesium-hercynite material and a protective layer attached to the low-thermal-conductivity magnesium-hercynite material, and the protective layer is composed of a ceramic material. The magnesium-iron-aluminum spinel material with the low thermal conductivity is composed of magnesium-iron-aluminum oxide, the thermal conductivity coefficient of the magnesium-iron-aluminum oxide is smaller than 0.5 W/mK, and the magnesium-iron-aluminum oxide is composed of MgO, Fe2O3 and Al2O3. By using the magnesium hercynite material with low thermal conductivity and the attached protective layer, the composite material realizes a lower thermal conductivity coefficient, so that the material has wide application potential in the fields of thermal isolation and energy conservation, heat conduction and energy loss can be effectively reduced, and the service life of the material is prolonged. Meanwhile, the problem that the environment is polluted after harmful substances contained in the raw materials are used is solved, the environment is protected, and the pollution to the environment is reduced.
本发明涉及晶石砖制备技术领域，公开了一种低导热多层复合镁铁铝尖晶石砖，包括多个层次的材料，每个层次由一层低导热性的镁铁铝尖晶石材料和一层附着在其上的保护层构成，且所述保护层由陶瓷材料构成，所述低导热性的镁铁铝尖晶石材料由镁铁铝氧化物组成，其导热系数小于0.5W/mK，所述镁铁铝氧化物具有以下化学组成：MgO:Fe2O3:Al2O3。通过使用低导热性的镁铁铝尖晶石材料和附着的保护层，复合材料实现了较低的导热系数，这使得该材料在热隔离和节能领域具有广泛应用的潜力，能够有效减少热传导和能量损失，同时解决了原料中含有有害物质使用后会对环境造成污染的问题，对环境进行保护降低了对环境的污染性。
