Preparation method of high-content waste electroceramic-based non-fired refractory brick
The invention discloses a method for preparing an unfired refractory brick from a high-content waste electrical porcelain base, and relates to the technical field of refractory materials. The preparation method comprises the following steps: by taking waste electroceramics, bauxite clinker and clay as raw materials, sodium silicate as a binding agent and aluminum dihydrogen phosphate and metakaolin (uniformly mixed with the sodium silicate in advance) as additives, uniformly mixing the raw materials and the additives/binding agent according to a certain proportion and sequence, drying at room temperature, performing compression molding by adopting a dry pressing method, drying at room temperature, and performing low-temperature heat treatment, thereby obtaining the product. And the baking-free refractory brick with excellent performance is obtained. The baking-free refractory brick can be used at the temperature ranging from 1100 DEG C to 1300 DEG C, is low in preparation cost and has wide application in the field of high temperature resistance.
本发明公开了一种高含量废电瓷基制备免烧成耐火砖的方法，涉及耐火材料技术领域。本发明以废电瓷、铝矾土熟料和粘土为原料，水玻璃为结合剂，磷酸二氢铝和偏高岭土(预先和水玻璃混匀)为添加剂，按一定比例和顺序将原料、添加剂/结合剂混合均匀，经室温干燥后，采用干压法压制成型并于室温下干燥并进行低温热处理，获得性能优良的免烧成耐火砖。所述的免烧成耐火砖可在1100～1300℃温度范围内温度下使用，制备成本低，在耐高温领域具有广阔的应用。
