Preparation method of low-thermal-conductivity aluminum-silicon porous structure refractory brick
The invention relates to a preparation method of a low-thermal-conductivity alumina-silica porous structure refractory brick, which mainly uses alpha-Al2O3 powder, mullite micro powder, silica micro powder, a silicic acid aqueous solution, short-cut mullite high-temperature-resistant fiber and a water glass solution as raw materials, and comprises the following specific steps: 1, preparation of thermal insulation aggregate: preparing the thermal insulation aggregate; 2, as the working layer is coated with the lightweight aggregate, the lightweight aggregate in a certain area exists in the internal structure of the sample, heat encounters the porous lightweight aggregate after entering the material through a working surface, the heat transfer path is increased, the heat transfer speed to the outside is reduced, the heat loss is reduced, and meanwhile, the material contains compact aggregate, so that the heat loss is reduced; compared with a common product, the capacity of the whole structure for bearing external mechanical stress is remarkably enhanced.
一种低导热铝硅质多孔结构耐火砖的制备方法，主要使用原料有α‑Al2O3粉、莫来石微粉、硅微粉、硅酸水溶液、短切莫来石耐高温纤维、水玻璃溶液，其具体步骤分为1.保温骨料的制备，保温骨料；2.工作层包覆，由于采用轻质骨料，试样内部结构中存在一定区域的轻质骨料，热量在通过工作面进入材料内部后，遇到多孔轻质骨料，热量传递路径增加，减少了热量的向外界递速度，在保证热量散失量下降的同时，由于材料中含有致密骨量，相比于普通制品，本发明的整体结构承受外界机械应力的能力显著增强。
