Description
技术领域
本发明涉及耐火环保材料技术领域,具体涉及一种低导热硅莫砖及其制备方法。
背景技术
新型干法水泥窑的上、下过渡带与烧成带相邻,常常经受着比烧成带更苛刻的使用环境,是整个水泥窑***选材中最难解决的部位,现在该部普遍使用硅莫砖为衬砖。
目前市场销售的硅莫砖大多使用一级或特级铝矾土,个别企业还添加有电熔刚玉以提高产品高温性能及抗侵蚀能力,但这同时增大了硅莫砖的导热系数,导热系数的增高使得水泥窑内热量损失较快,吨水泥燃料消耗增高,筒体温度升高,易使筒体发生变形,造成筒体使用寿命变短,变形的筒体使得窑内耐火材料砖衬受力不均,易发断裂和破损,造成砖衬使用寿命降低。
发明内容
本发明为了解决现有技术的不足之处,提供了一种低导热硅莫砖及其制备方法,具有耐火、隔热双重功能,导热系数低等优点。
为解决上述技术问题,本发明采用如下技术方案:
一种低导热硅莫砖,包括工作层和保温层,工作层与保温层通过压制连接在一起,工作层包括骨料、粉料、抗氧化剂和结合剂,以质量份配比计,其制备原料如下:骨料:粒度0-1mm的微孔莫来石10-15份,粒度1-3mm的微孔莫来石15-30份,粒度3-5mm的微孔莫来石15-20份;粉料:粒度<0.074mm的微孔莫来石20-25份,粒度<0.074mm的碳化硅细粉10-15份;抗氧化剂3-5份;结合剂:聚乙烯醇溶液3-5份;
保温层包括骨料、粉料、复合有机造孔剂和结合剂,以质量份配比计,其制备原料如下:骨料:粒度0-5mm的废旧硅莫砖颗粒50-60份,粒度0-3mm的微孔莫来石10-20份;粉料:粒度<0.074mm的微孔莫来石细粉5-10份,粒度<0.074mm的废旧硅莫砖细粉20-30份;复合有机造孔剂5-10份;结合剂:聚乙烯醇溶液3-5份。
抗氧化剂为金属硅粉与金属铝粉按 (1-2):1质量比混合,金属硅粉与金属铝粉混合后的混合物的平均粒度<70mm。
复合有机造孔剂为稻壳灰与无烟煤粉按(1-3):(1-2)质量比混合,稻壳灰与无烟煤粉混合后的混合物的平均粒度<0.05mm。
聚乙烯醇的分子量为25-30万,聚乙烯醇溶液的密度为1.01-1.02 g/cm3。
低导热硅莫砖的制备方法,包括以下步骤:
(1)配料:
A、工作层:将工作层所需的骨料倒入混碾机内,接着加入结合剂,先混碾5min,然后加入工作层所需的粉料和抗氧化剂,再混碾10min,形成工作层泥料,备用;
B、保温层:将保温层所需的骨料倒入混碾机内,接着加入结合剂,先混碾5min,然后加入保温层所需的粉料和复合有机造孔剂,再混碾10min,形成保温层泥料,备用;
(2)用隔板将预设在630T摩擦压力机上的模具内的腔内分隔为工作层隔室和保温层隔室,工作层隔室和保温层隔室的长度尺寸比为(1-3):(1-2),接着将步骤(1)中的工作层泥料和保温层泥料分别加入工作层隔室内和保温层隔室内,然后抽出隔板,操作630T摩擦压力机对模具进行冲压成型作业,制成砖坯;
(3)将步骤(2)制成的砖坯自然干燥24h,然后在110℃温度下烘干,烘干时间≥12h;
(4)将烘干后的砖坯装入窑内,砖坯在窑内保温5~15h,保温的温度为1300℃~1450℃,自然冷却后,即得产品。
本发明与现有技术相比,本发明具有以下有益效果:本发明以莫来石为主要原料,莫来石具有耐高温、强度高的优点。本发明产品加入复合有机造孔剂,降低保温层的体积密度,增大气孔率,导热系数降低,从而工作层和保温层的整体导热系数降低,经测试使用在水泥窑前后过渡带及窑尾时能降低筒体表面温度,相对于市场上同类产品低10~30℃。本发明保温层中的骨料采用了废旧硅莫砖,降低了成本,实现了废旧资源的重复利用,减少了固体废弃物的排放。
