Magnesia-calcium refractory material with high erosion resistance and preparation method thereof
The magnesium-calcium refractory material is prepared from the following raw materials in parts by weight: 60-80 parts of magnesium-calcium sand with the particle size of more than 3 and less than or equal to 7mm, 45-60 parts of magnesium-calcium sand with the particle size of more than 1 and less than or equal to 3mm, 30-50 parts of magnesium-calcium sand with the particle size of more than 0 and less than or equal to 1mm, 20-35 parts of magnesium-calcium sand with the particle size of more than 0 and less than or equal to 1mm, 10-15 parts of magnesium-calcium sand with the particle size of less than or equal to 0.088 mm, 25-45 parts of 200-mesh fused magnesite, 5-10 parts of expanded graphite and 1-5 parts of nano titanium dioxide. 1-5 parts of nano zirconium dioxide and 2-4 parts of a binding agent. The hydration resistance of the magnesia-calcium brick can be effectively improved by adding the nano titanium dioxide, cracks can be effectively prevented by adding the nano zirconium dioxide, external moisture is prevented from entering the magnesia-calcium brick, the hydration resistance of the magnesia-calcium brick is further improved, and then the magnesia-calcium brick with high erosion resistance is obtained.
本发明涉及一种抗侵蚀性能强的镁钙质耐火材料及其制备方法，是由下列重量份数的原料制备而成：3＜粒度≤7mm镁钙砂60～80份，1＜粒度≤3mm镁钙砂45～60份，0＜粒度≤1mm镁钙砂30～50份，0＜粒度≤1mm镁钙砂20～35份，粒度≤0.088mm镁钙砂10～15份，200目电熔镁砂25～45份，膨胀石墨5～10份，纳米二氧化钛1～5份，纳米二氧化锆1～5份，结合剂2～4份。本发明加入纳米二氧化钛可以有效提高镁钙砖抗水化性，加入纳米二氧化锆可以有效的阻止裂纹的产生，避免外界水分进入，进一步提高镁钙砖抗水化性，进而获得抗侵蚀性能强的镁钙砖。
