High-strength refractory mortar and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to high-strength refractory mortar and a preparation method thereof. The high-strength refractory mortar comprises the following components in percentage by weight: 50%-70% of white corundum powder, 10%-20% of high aluminum powder, 3%-6% of superfine alumina powder, 5%-8% of kyanite powder, 4%-6% of white mud, 1%-1.5% of modified starch, 1%-2% of bentonite, 1%-2% of lepidolite powder, 0.2%-0.5% of sodium carboxymethyl cellulose and 0.2%-0.5% of sodium tripolyphosphate. The low-temperature performance of traditional mortar is improved, and after construction is completed and natural drying is conducted, the bonding force is high; the use temperature is 25-1300 DEG C, the strength is high after normal-temperature drying, the defect that traditional daub does not have normal-temperature strength is overcome, and the refractoriness reaches 1810 DEG C after high-temperature sintering.
本发明属于耐火材料技术领域，具体涉及一种高强度耐火胶泥及其制作方法。涉及的一种高强度耐火胶泥的组分即重量百分比为：白刚玉粉50%‑70%、高铝粉10%‑20%、超细氧化铝粉3%‑6%、蓝晶石粉5%‑8%、白泥4%‑6%、改性淀粉1%‑1.5%、膨润土1%‑2%、锂云母粉1%‑2%、羧甲基纤维素钠0.2%‑0.5%、三聚磷酸钠0.2%‑0.5%。本发明改善了传统胶泥的低温性能，在施工完成自然干燥后，粘接力强；使用温度为25‑1300℃，常温干燥后强度大，解决了传统胶泥没有常温强度的缺陷，高温烧结后耐火度达1810℃。
