Description
技术领域
本发明涉及建材用高温材料领域，具体涉及一种5000T水泥窑窑口专用浇注料。
背景技术
目前我国新型干法水泥生产线发展迅速，水泥产能已严重过剩。因此，水泥生产企业提高单位生产效率，降低生产成本，是实现利润最大化的必由之路。而提高水泥生产线的运转率是提高水泥窑生产效率的重要条件。然而水泥窑窑口的寿命对整条生产线的运转周期有着重要的影响。水泥窑的窑口使用条件恶劣，除承受高达1400℃高温外，还承受水泥窑熟料连续出料压力，篦冷机来的二次风造成的热应力，回转窑回转机械应力，氯碱侵蚀对其带来的影响，因而对水泥窑窑口使用的浇注料的综合性能提出了更高的要求。当前常见的水泥窑窑口的使用寿命3到8个月不等，这样的寿命仍不能满足客户的需求。影响其使用寿命的主要原因是当前的耐火浇注料材料的力学性能，热性能差，各项性能不稳定，同时水泥窑窑口也不抗水泥窑内气氛的化学侵蚀，制约了水泥窑生产线运转率的提高，影响了水泥厂家的经济效益。
此外，当前的水泥窑窑口浇注料存在施工性能差的缺陷，容易导致浇注料偏析，气孔多，气孔分布不均匀等缺点，从而也降低了水泥窑窑口的使用寿命。

上述实施例中所用的各组分是本领域技术人员公知的产品，在市场上均可购买到，其中合成碳硅石、钛酸锶、棕刚玉、钢纤维的添加，有利于浇注料的耐磨性，热震性；红柱石具有微膨胀性；碳酸锆的引入使得浇注料在使用过程中获得良好的性能，碳酸锆分解形成具有良好性能的高活性氧化锆，以及分解过程中形成的微孔，都有利于提高材料的抗热震性，提高抗侵蚀性，避免浇注料发生开裂、掉落等现象；同时硅酸锌、氧化铝微粉，氧化铽，在使用中会逐步发生反应，生成性能较好的原位铝锌尖晶石，提高浇注料的组织均匀性，提高浇注料的抗酸碱性能，抗化学侵蚀性能。加入的Tc2O7，磺化苯乙烯-马来酸酐共聚物，聚醚性聚羧酸可以改善浇注料的可工作时间，改善浇注料施工时的气孔的分布，流动性能，根据温度不同，可以适当调节加入量；加入的C5H10N6O2产生连通的微气孔，使得烘烤时产生的蒸汽容易排出。采用上述的方案后，可获得一种性能良好的浇注料，使得浇注料制备的窑口的使用寿命延长至2倍以上。
上述实施例1-3的水泥窑窑口专用浇注料 按以下方法制备：将各组分混合搅拌均匀，再加入适量的水混合强力搅拌均匀，再然后成型经常规养护和烘烤后使用。
上述实施例1-3 的物理指标比较见下表：
