Modified glass fiber reinforced corundum-mullite castable and preparation method thereof
The invention discloses a modified glass fiber reinforced corundum-mullite castable and a preparation method thereof, and belongs to the technical field of unshaped refractory materials. The castable comprises 38 to 48% of compact corundum particles, 20 to 30% of mullite particles, 16 to 20% of compact corundum powder, 2 to 5% of silica powder, 5 to 10% of activated alumina powder, 1 to 3% of a composite additive, 0.05 to 0.15% of a water reducer, 0.2 to 0.6% of modified glass fiber and 7.5 to 8.5% of additional silica sol. Wherein the modified glass fiber is prepared by firing glass fiber at a high temperature of 350-400 DEG C, then adding the glass fiber into a solution containing a silane coupling agent, soaking while stirring, and then carrying out ultrasonic treatment. The obtained castable has high low-temperature strength, the high-temperature performance of the castable is improved, and large-scale industrial application of the silica sol combined corundum-mullite castable is facilitated.
本发明公开了一种改性玻璃纤维增强的刚玉‑莫来石浇注料及其制备方法，属于不定形耐火材料技术领域。该浇注料包括：致密刚玉颗粒38～48％，莫来石颗粒20～30％，致密刚玉粉16～20％，硅微粉2～5％，活性氧化铝粉5～10％，复合添加剂1～3％，减水剂0.05～0.15％，改性玻璃纤维0.2～0.6％，外加硅溶胶7.5～8.5％；其中：改性玻璃纤维通过将玻璃纤维在350‑400℃温度下进行高温灼烧后，再加入含硅烷偶联剂的溶液中搅拌下浸泡，然后超声处理制备得到。所得浇注料具有较高的低温强度，同时改善了其高温性能，有利于硅溶胶结合刚玉‑莫来石浇注料的大规模工业应用。
