Description
技术领域
本发明涉及回转窑隔热砖技术领域，特别涉及一种复合耐火材料轻质回转窑隔热砖。
背景技术
回转窑是指旋转煅烧窑，回转窑按处理物料不同可分为水泥窑、冶金化工窑和石灰窑，水泥窑主要用于煅烧水泥熟料，分干法生产水泥窑和湿法生产水泥窑两大类，冶金化工窑则主要用于冶金行业钢铁厂贫铁矿磁化焙烧，铬、镍铁矿氧化焙烧，耐火材料厂焙烧高铝钒土矿和铝厂焙烧熟料、氢氧化铝，化工厂焙烧铬矿砂和铬矿粉等类矿物，石灰窑用于焙烧钢铁厂、铁合金厂用的活性石灰和轻烧白云石，国内大中型水泥回转窑所采用的的砖块为普通材质的砖块，在煅烧的过程中，容易造成砖块发生断裂，容易造成回转窑的内部结构发生变化，从而导致使用寿命减小，砖块中采用二氧化硅的比例较高，使得回转窑的砖块更加容易导热，回转窑内部的热量散发更加的快，从而造成需要更多的燃料，导致需要更多的燃料，企业的成本增加。

需要说明的是，本发明为一种复合耐火材料轻质回转窑隔热砖，其中：将轻质部分、重质部分、保温部分、耐火部分和隔热部分的烧成温度为1500～1550℃，且烧制时间为10～15小时，烧制完成后保温2～3小时，进而制成砖块长宽高的尺寸为240毫米、115毫米和53毫米，且该砖块的密度为1800～1900kg/m3的砖块，轻质部分包括以下重量份数的原料，刚玉20～35份、电熔莫来石20～40份、炼焦15～25份、木钙10～25份、石膏10～20份、中温石粉6～12份、纤维颗粒料5～13份、滑石泥3～9份、氟化钠溶液3～8份、聚氯乙烯颗粒1～4份、二氧化硅1～5份、二氧化钛1～3份、氧化钙0.5～2.5份、氧化镁0.5～3份、硅粉0.5～3份，轻质部分采用刚玉和电熔莫来石作为主要原料，以炼焦、木钙石膏、中温石粉为辅料，在通过添加少许二氧化硅、二氧化钛、氧化钙、氧化镁的氧化物，从而达到轻化砖块的整体结构，减轻砖块的整体重量，方便砖块的搬运和堆砌，方便工人拿去砖块，重质部分包括以下重量份数的原料，电熔白刚玉30～50份、电熔莫来石25～40份、红柱石20～35份、陶土10～18份、氧化铝5～12份、木钙8～15份、黄糊精1～3份、二氧化硅1～5份，重质部分采用刚玉和电熔莫来石作为主要原料，且占有的质量分数的比例高于其它原料占有的比例，且通过陶土增加各个材质间的粘度，避免砖块容易发生断裂，减小砖块的不必要的损坏，保温部分包括以下重量份数的原料，刚玉10～25份、电熔莫来石10～30份、滑石粉8～12份、英石8～15份、粉状白灰5～10份、聚苯颗粒5～16份、膨化珍珠岩颗粒5～18份、聚丙烯酰胺3～9份、硅酸铝纤维2～6份、硫酸铝1～6份、渗透剂1～3份、无机粘结剂2～8份，膨胀珍珠岩的以其良好的保温效能，在1500～1550℃的高温的情况下，膨化珍珠岩颗粒会迅速膨胀，可以填充砖块内部和砖块之间的细缝，并且在自身具有保温性能的情况下，会进一步减小回转窑砖块的温度流失，具有很好的保温效果，耐火部分包括以下重量份数的原料，氧化铝10～12份、硅酸钠10～15份、氮化硅5～10份、陶粒5～8份、聚醋酸乙烯树脂4～12份、环氧树脂4～10份、纳米氧化钛2～4份和纳米氧化硅1～2份，纳米氧化钛对有害气体也具有吸收功能，将纳米氧化钛涂在含磷酸钙的砖块上可持续长期地吸收不同酸碱性气体，和回转窑中挥发的碱性气体放生反应，减小碱性气体对人体的危害，隔热部分包括以下重量份数的原料，刚玉10～30份、电熔莫来石15～25份、纳米氧化锆粉末8～12份、氧化钙3～5份、氧化钇3～5份、二氧化钛1～3份、氧化镁1～3份、页岩粉末0.5～2份、二氧化硅0.5～2份、聚氯乙烯颗粒0.5～1份、有机烧失物0.5～1份，刚玉和电熔莫来石作为砖体的主要组成，可以提高强度和硬度的有效方法，减小二氧化硅的含量，由于二氧化硅可以加快砖块的导热性能，此时通过减少二氧化硅的比例，增加氧化锆的比例，使得氧化锆在回转窑煅烧时产生的高温的情况下可以将氧化锆、二氧化钛、氧化镁相互结合、使得砖块隔热部分可以减小砖块的热量散发，其中加入聚氯乙烯颗粒，由于聚氯乙烯具有阻燃性，在回转窑在使用时，聚氯乙烯颗粒在240℃-340℃会燃烧分解出氯化氢气体和含有双键的二烯烃，然后在400-470℃发生碳的燃烧，燃烧过程会夺去一部分氢生成氯化氢，而氯化氢极易与生成的水组合形成盐酸气起到一定的阻燃效果。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
