抗腐蚀浇注料及其制备方法
技术领域
本发明属于耐火材料的技术领域，具体涉及一种抗腐蚀浇注料及其制备方法。
背景技术
垃圾焚烧炉多个部位由于温度较高且物料冲刷严重，物料碱性成份重，化学侵蚀作用强，传统耐火材料在该部位使用，导致损坏频繁，寿命均不长。目前市场上现有的耐磨浇注料普遍存在耐磨性能不高、耐高温性能较差和抗热震性能不强等缺陷，使用寿命一般很短，甚至两到三个月已基本损坏，已很难满足市场的需求。
发明内容
本发明的目的在于针对现有技术的不足，提供一种抗腐蚀浇注料，耐磨性能高、耐高温性能较好和抗热震性能强。为实现上述目的，本发明所采用的技术方案是：
抗腐蚀浇注料，由以下原料按照质量份数组成，废高压电瓷粉55-60份，莫来石25-30份，铝酸盐水泥10-14份，石英砂5-10份，苛性苦土2-4份，硅微粉2-5份，助剂1-3份。
废高压电瓷粉要求Al2O3≥50％，Fe2O3≤2.5％。
其中，所述的铝酸盐水泥的Al2O3含量为58％～72％的铝酸钙水泥。
所述的助剂为柠檬酸钠、三聚磷酸钠、六偏磷酸钠、硼酸中的一种或几种混合。
该抗腐蚀浇注料的制备方法，包括以下步骤：将废高压电瓷粉、莫来石、石英砂、苛性苦土研磨，平均粒径≤180目，得到研磨混合物，研磨混合物与铝酸盐水泥、硅微粉、助剂充分混合均匀，加入4～7份的水，进一步充分均匀混合，即得抗腐蚀浇注料。
本发明提供的抗腐蚀浇注料及其制备方法，得到的浇注料具有较好的耐高温、耐碱、抗热震性能，使用寿命长，并且浇注料具有良好施工性能。
