High-temperature refractory mortar with controllable expansibility and preparation method thereof
The invention belongs to the field of refractory materials, and particularly discloses expansibility-controllable high-temperature refractory mortar which comprises the following components: 30-70 wt% of runner brick reclaimed materials subjected to vacuum impregnation treatment, 10-60 wt% of mullite sand raw materials, 1-6 wt% of Guangxi mud and 3-9 wt% of aluminum waste, and the total amount of the raw materials is 100 wt%. According to the invention, the recovered runner brick subjected to vacuum impregnation treatment, the aluminum waste material and the mullite sand are used as the raw materials, so that the environmental pollution caused by stacking of a large amount of solid waste is solved; and moreover, due to the volume expansion effect accompanied by phase change of the mullite sand under the high-temperature condition, fireclay gaps can be filled more tightly, and the problem of steel seepage caused by fireclay shrinkage or untight filling under the high-temperature condition is effectively solved.
本发明属于耐火材料领域，具体公开了一种膨胀性可控的高温耐火泥，包括以下组分：真空浸渍处理后的汤道砖再生料：30‑70wt·%，莫来砂生料：10‑60wt·%，广西泥1‑6wt·%，铝废料3‑9wt·%，上述原材料总量为100wt·%，同时外加上述原材料总量0.1‑1wt·%的分散剂、0.1‑0.8wt·%的增稠剂和2‑6wt·%的结合剂，本发明以回收的真空浸渍处理后的汤道砖、铝废料和莫来砂为原料不仅解决了固态废弃物大量的堆存造成的环境污染，而且莫来砂在高温条件下发生相变伴随的体积膨胀效应可使火泥缝隙填充的更加紧密，有效解决高温条件下火泥收缩或填充不紧密等导致的渗钢问题。
