Carbon-ceramic composite thermal insulation material and preparation method thereof
The invention discloses a carbon-ceramic composite thermal insulation material which comprises the following raw materials: aluminum oxide, Y2O3 and carbon nanotubes, the ratio of the aluminum oxide to the carbon nanotubes is 1: 0.05-1: 0.2, and the addition amount of the Y2O3 is 0.05% of the mass of the aluminum oxide. The preparation method comprises the following steps: mixing aluminum oxide, Y2O3 and carbon nanotubes, and carrying out ball milling to obtain ceramic slurry; drying and granulating the ceramic slurry; carrying out compression molding on the granulated powder, and then drying and sintering; the sintering temperature is increased from the room temperature, the heating rate is 20 DEG C/min, when the temperature reaches 200 DEG C, the heating rate is 5 DEG C/min until the temperature reaches 1500 DEG C, heat preservation is conducted for 2-5 h, and furnace cooling is conducted. The problem that existing porous ceramic is low in heat insulation performance is solved, the porous ceramic is used as a high-temperature heat insulation material, heat loss can be effectively resisted, a good heat preservation effect is achieved, and the purpose of saving energy is achieved.
本发明公开了一种碳陶复合隔热材料，原料包括：氧化铝、Y2O3和碳纳米管，且，氧化铝：碳纳米管＝1：0.05～1：0.2，Y2O3的添加量为氧化铝质量的0.05％。制备过程包括：将氧化铝、Y2O3和碳纳米管混合，球磨，获得陶瓷料浆；将陶瓷料浆烘干、造粒；将造粒好的粉体模压成型，然后烘干、烧结；烧结温度从室温开始升温，升温速率为20℃/min，当温度达到200℃时，升温速率为5℃/min，直到1500℃，保温2～5h，随炉冷却。本发明解决了现有多孔陶瓷隔热性低的问题，用于作为高温隔热材料，能够有效地抵制热量的散失，起到良好的保温效果，达到节约能源的目的。
