Aluminum phosphate wear-resistant brick as well as preparation method and application thereof
The invention provides an aluminum phosphate wear-resistant brick as well as a preparation method and application thereof, and belongs to the technical field of refractory materials. The preparation method comprises the following steps: preparing N-doped carbon nitride, mixing the N-doped carbon nitride with silicon carbide powder, modifying the surface of the N-doped carbon nitride with polydopamine, adding the N-doped carbon nitride into silicon dioxide sol, calcining, adding the N-doped carbon nitride into aluminum phosphate sol, adding a product into high-alumina bauxite, uniformly stirring and mixing, mechanically pressing, and calcining to obtain the aluminum phosphate wear-resistant brick. The prepared aluminum phosphate wear-resistant brick is good in wear resistance, good in mechanical property, good in formability, good in fire resistance and high temperature resistance, wide in raw material source and low in cost, the prepared product effectively avoids the problems of cracking, falling and the like, and the aluminum phosphate wear-resistant brick has wide application prospects.
本发明提出了一种磷酸铝耐磨砖及其制备方法和应用，属于耐火材料技术领域。制备N‑掺杂氮化碳，与碳化硅粉混合，表面经聚多巴胺改性后，加入二氧化硅溶胶中，煅烧，加入磷酸铝溶胶中，产物加入高铝矾土中，搅拌混合均匀，机压成型，煅烧，制得磷酸铝耐磨砖。本发明制得的磷酸铝耐磨砖耐磨性能好，力学性能佳，成型性能好，耐火和耐高温性能好，原料来源广，成本较低，制得的产品有效避免了开裂、脱落等问题，具有广阔的应用前景。
