Preparation method of high-strength low-thermal-conductivity zirconium oxide complex-phase refractory insulating brick
The invention relates to a preparation method of a high-strength low-thermal-conductivity zirconium oxide complex-phase refractory insulating brick, and belongs to the technical field of refractory insulating bricks. The preparation method of the high-strength low-thermal-conductivity zirconium oxide complex-phase refractory insulating brick comprises the following steps that: with zirconium oxidehollow spheres, calcium-stabilized zirconium oxide fine powder, calcium-stabilized zirconium oxide micro powder and floating beads taken as raw materials, an adhesive and poly-light spheres are added; andmixing, ageing, compression molding, drying and sintering are performed to obtain the high-strength low-thermal-conductivity zirconium oxide complex-phase refractory insulating brick. The productprepared by the invention not only has higher strength, but also has low thermal conductivity and low production cost, and has remarkable economic benefits.
本发明涉及一种高强度低导热氧化锆复相耐火保温砖的制备方法，属于耐火保温砖技术领域。本发明所述的高强度低导热氧化锆复相耐火保温砖的制备方法，以氧化锆空心球、钙稳定氧化锆细粉、钙稳定氧化锆微粉和漂珠为原料，添加粘合剂和聚轻球，经过混料、困料、压制成型、干燥和烧成制成。本发明制备的产品不仅具有较高的强度，还具有低导热率，生产成本低，具有显著的经济效益。
