Mullite composite refractory brick and processing technology thereof
The invention discloses a mullite composite refractory brick and a processing technology thereof. The mullite composite refractory brick comprises quartz sand, clay, polystyrene, mullite and a supplement. The bending strength and fracture toughness of the mullite composite refractory brick can be effectively enhanced, and the anti-seismic property of the mullite composite refractory brick can be effectively enhanced, so that the mullite composite refractory brick is not easy to damage during use, and the service life is prolonged; carrying out surface modification treatment on the silicon carbide nanowire under the action of a silane coupling agent; phenol, a formaldehyde aqueous solution and oxalic acid react to generate a layer of smooth phenolic resin through in-situ polymerization on the surface of the silicon carbide nanowire, the silicon carbide nanowire coated with a carbon layer is formed after carbonization treatment, the silicon carbide nanowire is added into the refractory brick to be compounded with aluminum oxide, the bending strength and fracture toughness of the refractory brick can be effectively improved, and then the anti-seismic property of the refractory brick is enhanced. Boron carbide and silica sol are compounded and added into the refractory brick, growth of a mullite phase is facilitated, volume expansion is generated, and the thermal shock resistance of the refractory brick can be effectively improved.
本发明公开了一种莫来石复合耐火砖及其加工工艺，包括石英砂、黏土、聚苯乙烯、莫来石和补充剂。本发明可有效加强其弯曲强度和断裂韧性，可有效加强莫来石复合耐火砖的抗震性能，使得莫来石耐火砖在使用时不易受损，延长使用寿命；碳化硅纳米线在硅烷偶联剂作用下进行表面改性处理；苯酚、甲醛水溶液和草酸反应在碳化硅纳米线表面原位聚合生成一层平滑的酚醛树脂，碳化处理后，形成包覆碳层的碳化硅纳米线，加入到耐火砖中与氧化铝进行复合，可有效提高耐火砖的弯曲强度和断裂韧性，进而加强耐火砖的抗震性能；碳化硼和硅溶胶进行复合加入到耐火砖中，有利于莫来石相的生长，产生体积膨胀，可有效提高耐火砖的抗热震性能。
