Preparation method of lightweight heat-insulating magnesium oxide brick
The invention relates to a preparation method of a lightweight heat-insulating magnesium oxide brick, and belongs to the technical field of heat-insulating bricks. According to the preparation methodof the lightweight heat-insulating magnesium oxide brick, magnesia is used as a main material, and the lightweight heat-insulating magnesium oxide brick is prepared by combining a gel casting method with a foaming process. The product prepared by the invention not only has excellent refractoriness and erosion resistance, but also has relatively high porosity, relatively low heat conductivity coefficient and excellent heat-insulating performance.
本发明涉及一种氧化镁轻质隔热保温砖的制备方法，属于保温砖技术领域。本发明所述的氧化镁轻质隔热保温砖的制备方法，以镁砂为主料，利用凝胶注模方法结合发泡工艺制得氧化镁轻质隔热保温砖。本发明制备的产品不仅具有优异的耐火度、抗侵蚀性，还具有较高的气孔率、较低的导热系数，具有优良的保温隔热性能。
