Magnesium-calcium baking-free brick and preparation method thereof
The invention relates to the technical field of magnesium-calcium baking-free bricks, and discloses a magnesium-calcium baking-free brick, which is prepared from the following raw materials in parts by weight: 60 to 100 parts of magnesium-calcium sand, 20 to 40 parts of fused magnesia, 5 to 10 parts of crystalline flake graphite, 3 to 8 parts of zirconium oxide micro powder, 3 to 8 parts of silicon carbide micro powder, 2 to 5 parts of modified asphalt, 1 to 3 parts of binding agent and 6 to 18 parts of additive, the additive is one of TiO2 or Fe2O3, and the binding agent is paraffin. According to the magnesium-calcium baking-free brick, by adding the binding agent and the additive, the sintering of the magnesium-calcium brick can be promoted, the compactness of the product is improved, the hydration resistance of the magnesium-calcium brick is enhanced, the use performance of the magnesium-calcium brick is further improved, and the problems that the magnesium-calcium brick is hydrated, the structure of the magnesium-calcium brick is loose and the service life of the magnesium-calcium brick is prolonged due to the fact that free CaO is inevitably in contact with outside water are solved. And the problem of direct scrapping caused by reduction or even loss of various use performances is solved, so that the service life of the magnesia carbon brick is prolonged.
本发明涉及镁钙免烧砖技术领域，且公开了一种镁钙免烧砖，包括以下重量份数配比的原料：镁钙砂60～100份、电熔镁砂20～40份、鳞片石墨5～10份、氧化锆微粉3～8份、碳化硅微粉3～8份、和改性沥青2～5份、结合剂1～3份和添加剂6～18份，所述添加剂为TiO2或Fe2O3的一种，所述结合剂为石蜡。该镁钙免烧砖，通过加入结合剂和添加剂，能够促进镁钙砖的烧结，提高制品的致密度，增强了镁碳砖的抗水化性能，进而提高镁钙砖的使用性能，解决了游离CaO不可避免的会接触到外界水分，从而导致镁钙砖发生水化，造成镁钙砖结构疏松，各项使用性能下降甚至丧失性能导致直接报废的问题，进而增强镁碳砖的使用寿命。
