Lightweight heat-insulating refractory material for tunnel kiln wall and preparation process of lightweight heat-insulating refractory material
The invention relates to the technical field of refractory materials, in particular to a light heat-insulating refractory material for a tunnel kiln wall and a preparation process of the light heat-insulating refractory material. The preparation method comprises the following steps: adding methacrylamide, trimethyl 2-phosphonoacrylate and a silane coupling agent KH570 to carry out graft modification on nano aluminum oxide, so as to prepare modified aluminum oxide powder; preparing calcium hexaluminate powder by taking aluminum hydroxide and light calcium carbonate as raw materials; coating the zirconium oxide powder on the surface of the calcium hexaluminate powder through a rolling balling process to prepare coated powder; finally, the modified aluminum oxide powder, the coating powder, silicon carbide and clay serve as main components, and the refractory brick is prepared after processing treatment. And pressing zirconium oxide powder on the surface of the refractory brick to prepare a finished product. The prepared refractory material has good high-temperature heat insulation performance, erosion resistance and fire resistance and flame retardance, and has a very wide application prospect.
本发明涉及耐火材料技术领域，具体是一种隧道窑窑墙用轻质隔热耐火材料及其制备工艺。本发明通过添加甲基丙烯酰胺、2‑膦酰基丙烯酸三甲酯和硅烷偶联剂KH570对纳米氧化铝进行接枝改性，制备得到改性氧化铝粉体；再以氢氧化铝和轻质碳酸钙为原料，制备得到六铝酸钙粉体；并通过滚动成球工艺将氧化锆粉体包覆在六铝酸钙粉体表面，制备得到包覆粉体；最后以改性氧化铝粉体、包覆粉体、碳化硅和黏土为主要成分，经加工处理后制备得到耐火砖；并在耐火砖表面压制氧化锆粉体，制备得到成品。本发明制备得到的耐火材料具有良好的高温隔热性能、抗侵蚀性能和耐火阻燃性能，具有非常广阔的应用前景。
