Description
技术领域
本发明涉及耐火材料技术领域，特别涉及一种高强耐火保温浇注料及其制备方法。
背景技术
高炉、热风炉管道等中，为了保证高温气体在输送过程中的温度，在管道内要砌筑耐火材料。在高温窑炉使用中，为保证窑炉的保温效果，同时提高窑炉内衬使用寿命，常采用由重质砖和轻质耐火材料组合砌筑，导致窑炉内衬热容量大，热效率降低。由于传统轻质节能材料具有气孔率大，吸水率高，强度相对较低，保温节能效果差的缺陷，不能直接用于工作层，必须用多层耐火材料砌筑，也使得管径增大，这使得设备重量和体积增加，材料消耗和成本增加。
发明内容
针对上述问题，本发明提供一种质量轻、强度高、导热系数低、整体性好的窑炉用耐火节能浇注料及其制备方法。
为达到上述目的，本发明采用的具体技术方案如下：
一种高强耐火保温浇注料，包括以下组分原料及重量份：包括以下组分原料及重量份：1-8mm轻质镁白云石50-55份，珍珠岩生矿5-10份，1-0mm轻质博耐特10-25份，200目轻质叶蜡石粉5-10份，325目轻质莫来石细粉5-10份，硅微粉5-10份，粒径2~3μm的Al2O3 微粉5-10份，铝酸盐水泥3-8份，0.25-1.5mm玻化微珠5-10份，六偏磷酸钠0.31份，防爆纤维0.3份。
优选的，所述轻质镁白云石由粒径1-3mm和3-8mm的两种颗粒级配而成，粒径3-8mm的颗粒占轻质镁白云石总重量的40%。
优选的，所述珍珠岩生矿的粒度为0-1mm。
优选的，所述氯化铝溶液的比重为1.25克每立方厘米。
优选的，所述防爆纤维为直径3μm，长度8mm的聚丙烯纤维。
一种高强耐火保温浇注料的制备方法，包括如下步骤：将方案中的各种原料加入搅拌机中搅拌混合，加入占其重量10-12%的氯化铝溶液搅拌均匀，搅拌好的物料注入模具，震动成型，养护24后进行烘烧，温度达到100℃时保温4h，温度达到450℃时保温8h，即可投入使用。
本发明的有益效果如下：本发明采用轻质镁白云石、轻质博耐特、玻化微珠作为基体，材料导热系数小，化学性质稳定，对酸、碱都有良好的抵抗性，隔热效果好、耐侵蚀。
本发明采用轻质叶蜡石粉，轻质莫来石细粉，硅微粉，粒径2~3μm的Al2O3 微粉，作为细粉填充骨料间的间隙，骨料表面凹凸不平，增大与细粉之间的接触比表面积，使得两者结合更紧密；采用氯化铝溶液、高铝水泥、珍珠岩生矿，硅微粉和Al2O3 微粉作为基质结合物质，通过氯化铝溶液化学结合作用将细粉和骨料粘结在一起高温下，同时在高温下可以生成反应产物磷酸铝，磷酸钙等物质，把骨料和细粉牢固的结合在一起，促进多相融合，从而提高浇注料的整体结合强度；其中的珍珠岩生矿是一种轻质料，随温度升高体积会膨胀，可以改变轻质材料随温度升高收缩线变化大的缺陷，不会导致轻质材料收缩变形，其高温下的膨胀正好可以逐步抵消材料的收缩，提高材料的稳定性。其比膨胀珍珠岩具有优异的性能，一是成本降低无需煅烧，而是膨胀珍珠岩经过煅烧后，不会继续膨胀，随温度升高只会导致轻质材料收缩。
本发明通过添加防爆纤维提高轻质材料中低温下的透气性，防爆纤维在烘烧过程软化、收缩、熔化，最后形成气孔并碳化，在材料内部形成网络气孔，打开通道，不仅可减轻材料内部应力，同时内部产生的微孔又能降低导热率，提高节能效果。因此，通过整个技术方案就可以实现材料内部结合牢固，同时可以实现低导热，体积不收缩不膨胀保持体积稳定的性能。
具体实施方式
