Antioxidant coating for ladle magnesia carbon brick
The invention relates to the technical field of coatings, and provides an anti-oxidation coating for ladle magnesia carbon bricks, the anti-oxidation coating comprises the following raw materials by weight: 30-50 parts of magnesia, 20-30 parts of alumina, 10-20 parts of tungsten carbide, 5-10 parts of a binder, 5-15 parts of clay, and 5-15 parts of boron glass; the binder is formed by mixing silica sol, styrene-acrylic emulsion and zirconium acetate according to the mass ratio of (3-8): 1: 1. By means of the technical scheme, the problem that in the prior art, when a magnesia carbon brick is applied to a steel ladle, the oxidation resistance is poor is solved.
本发明涉及涂料技术领域，提出了一种钢包镁碳砖用抗氧化涂料，原料包括以下重量份的组分：镁砂30‑50份、氧化铝20‑30份、碳化钨10‑20份、粘结剂5‑10份、黏土5‑15份、硼玻璃5‑15份；粘结剂由质量比为3‑8:1:1的硅溶胶、苯丙乳液和醋酸锆混合而成。通过上述技术方案，解决了现有技术中的镁碳砖在钢包中应用时抗氧化性能较差的问题。
