The invention relates to the technical field of bricking mud, and provides carbon-free corundum brick bricking mud for a steel ladle and a preparation method of the carbon-free corundum brick bricking mud. Comprising the following raw materials in parts by weight: 30-50 parts of magnesia powder, 5-15 parts of bauxite, 20-40 parts of corundum powder, 4-6 parts of aluminum oxide, 1-2 parts of high-temperature asphalt, 0.3-0.6 part of a thickening agent, 15-30 parts of a binding agent, 0.5-1 part of a dispersing agent, 1-2 parts of benzotriazole and 0.5-1 part of bis (2-ethoxyl) methyl tetradecyl chlorinated quaternary ammonium salt. By means of the technical scheme, the problems that in the prior art, building mud is low in fracture-resistant bonding strength and large in heating permanent linear variation are solved.
本发明涉及砌泥技术领域，提出了一种钢包无碳刚玉砖砌泥及其制备方法，包括以下重量份组分的原料：30‑50份镁砂粉、5‑15份铝矾土、20‑40份刚玉粉、4‑6份氧化铝、1‑2份高温沥青、0.3‑0.6份增稠剂、15‑30份结合剂、0.5‑1份分散剂、1‑2份苯并三唑、0.5‑1份二(2‑羟乙基)甲基十四烷基氯代季铵盐。通过上述技术方案，解决了现有技术中砌泥的抗折粘结强度低、加热永久线变化量大的问题。
