Preparation method of high-conductivity refractory material
The invention discloses a high-conductivity refractory material preparation method, which comprises: 1, uniformly mixing a refractory aggregate and polyvinyl alcohol, and loading into a mold for pre-molding; step 2, performing cold isostatic pressing treatment on the preformed mixed powder to obtain coarse slurry; 3, after the coarse slurry is subjected to spray drying, compacted powder is prepared and sieved, leaked materials are taken, and the water content is controlled to be 1%-4%; step 4, mixing the compacted powder with the conductive powder according to a mixing ratio of 1: 0.3; and 5, uniformly mixing the mixed powder, and carrying out microwave firing. The powder is dried and subjected to water control after being subjected to cold isostatic pressing, the bonding strength with the conductive powder is improved, the conductivity is further enhanced, and static electricity can be better conducted.
本发明公开了一种高电导率耐火材料的制备方法，包括以下步骤：步骤一，将耐火骨料与聚乙烯醇混合均匀，然后装入模具预成型；步骤二，预成型后的混合粉料进行冷等静压处理制得粗浆料；步骤三，将粗浆料喷雾干燥后，制得压实粉料并过筛取漏料，控制含水率份为1～4％；步骤四，将压实粉料混入导电粉料，混合比例为1:0.3；步骤五，将混合粉料混合均匀后进行微波烧制。将粉料进行冷等静压后干燥控水，增加与导电粉料粘结强度，进一步增强导电性能，可以更好地传导静电。
