Anti-hydration magnesium-calcium tundish coating and preparation method thereof
The invention belongs to the field of refractory materials. The invention provides a hydration-resistant magnesium-calcium tundish coating. The hydration-resistant magnesium-calcium tundish coating comprises the following components in parts by weight: 5-73 parts of dead burned magnesia particles, 20-88 parts of a calcium raw material, 1.1 to 1.3 parts of fibers, 3-5 parts of a nano binding agent,0.05 to 1 part of an organic plasticizer, 0.1 to 0.3 part of an explosion-proof agent and 1-2 parts of a water reducing agent. The invention further provides a preparation method of the hydration-resistant magnesium-calcium tundish coating. The organic plasticizer disclosed by the invention is beneficial to improving the plasticity and viscosity of the material and ensuring the construction performance of the coating, and does not fall off in the construction process, by compounding the fibers and the explosion-proof agent, capillary exhaust holes can be formed in the coating, so that the magnesium-calcium coating does not bulge when gas released by decomposition of water vapor and calcium raw materials is exhausted in the curing process, and does not collapse, peel off and the like in the quick baking process.
本发明属于耐火材料领域。本发明提供了一种抗水化镁钙质中间包涂料，包含如下重量份的组分：重烧镁砂颗粒5～73份；钙原料20～88份；纤维1.1～1.3份；纳米结合剂3～5份；有机增塑剂0.05～1份；防爆剂0.1～0.3份；减水剂1～2份。本发明还提供了一种抗水化镁钙质中间包涂料的制备方法。本发明的有机增塑剂有利于提高材料的塑性、粘性，保证涂料的施工性能，且施工过程不脱落；纤维及防爆剂的复配使用，可以在涂料内部形成毛细排气孔，保证镁钙质涂料在养护过程中水汽及钙原料分解放出的气体排出时不鼓包，快速烘烤时不崩塌、剥落等。
