Semi-silicon high-temperature foaming heat-insulating refractory material and preparation method thereof
The invention relates to a semi-silicon high-temperature foaming heat-insulating refractory material and a preparation method thereof, and relates to the technical field of heat-insulating refractory materials. The preparation method mainly comprises the following steps: mixing 26-54 wt% of low-aluminum aluminum-silicon natural raw materials, 40-65.5 wt% of silica, 0.5-4 wt% of kyanite, 0.2-0.5 wt% of a high-temperature foaming agent and 4 wt% of a soft clay binding agent according to the mass percentage to obtain a mixed raw material; grinding the mixed raw materials into 325 meshes by a wet method, dehydrating and granulating in a drying tower, and forming under the pressure of 100-120MPa to obtain a green body; and finally, putting the green body into a high-temperature furnace, preserving heat at 1500-1580 DEG C for 1-2 hours, calcining, cooling and discharging to obtain the semi-silicon high-temperature foaming heat-insulating refractory material. The semi-silicon high-temperature foaming heat-insulating refractory material disclosed by the invention takes silicon dioxide as a main chemical composition, through high-temperature calcination and in-situ foaming pore forming, a low-melting-point fluxing agent is not introduced, and the prepared product is low in heat conductivity coefficient, good in mechanical property and high in use temperature.
本发明涉及一种半硅质高温发泡隔热耐火材料及其制备方法，涉及隔热耐火材料技术领域。本发明主要包括以下步骤，按照质量百分比将26~54wt%的低铝铝硅质天然原料、40~65.5wt%的硅石、0.5~4wt%的蓝晶石、0.2~0.5wt%的高温发泡剂以及4wt%的软质黏土结合剂混合获得混合原料；随后将混合原料湿法共磨成325目、进入干燥塔脱水、造粒、经100~120MPa压力下成型得到坯体；最后将坯体置于高温炉中1500~1580℃保温1~2h煅烧，冷却出炉后即得到半硅质高温发泡隔热耐火材料。本发明所述的半硅质高温发泡隔热耐火材料以二氧化硅为主要化学组成，通过高温煅烧原位发泡成孔，未引入低熔点的助熔剂，所制备的制品不仅导热系数低、力学性能好且使用温度高。
