Description

一种钛酸盐片晶增强的耐火砖及其制备方法
技术领域
本发明涉及一种钛酸盐片晶增强的耐火砖及其制备方法，属于耐火材料领域。
背景技术
耐火砖是用耐火黏土或其他耐火原料烧制成的具有一定形状和尺寸的耐火材料，能耐1580℃-1770℃的高温。按制备工艺方法来划分可分为烧成砖、不烧砖、电熔砖(熔铸砖)、耐火隔热砖；按形状和尺寸可分为标准型砖、普通砖、特异型砖等。耐火砖可用作建筑窑炉和各种热工设备的高温建筑材料和结构材料，并在高温下能经受各种物理化学变化和机械作用。
近年来，国内耐火砖生产工艺发展迅速，市场上出现了种类繁多、性能各异的耐火砖。中国专利号为：200710062457.5的发明专利公开了一种硅质隔热耐火砖，本发明耐火砖由硅石细粉81-85％，珍珠岩15-19％，外加占上述主原料总重的下列辅料：铁鳞粉0.45-0.55％，水泥0.9-1.1％，石灰乳6.5-7.5％，纸浆1.95-2.2％组成，制备工艺为：将硅石细粉、珍珠岩按比例加入湿碾内，然后加入铁鳞粉、水泥干碾1-2分钟后，加入占主原料总重的1.8-2.2％的水，然后加入石灰乳，碾压10-15分钟，最后加入纸浆，碾压10-15分钟，出碾，成型制坯。采用上述原料和工艺制得的耐火砖虽然解决了现有粘土质隔热耐火砖存在荷重变形温度低、高温下易收缩、导热率较大、保温效果不好等缺陷，但是其耐火性和机械强度与国外耐火砖相比较，仍存在较大的差距，无法满足出口市场的需求。
发明内容
本发明所要解决的技术问题是提供一种钛酸盐片晶增强的耐火砖及其制备方法，以解决现有耐火砖机械强度低和耐火度低的问题。
为了解决上述问题，本发明采用如下技术方案：

一种钛酸盐片晶增强的耐火砖的制备方法，由下列步骤组成：
(1)将蛇纹石尾矿、粉煤灰提铝渣、硅钙渣、冶炼烟尘混合均匀，粉碎，过70-90目筛，800-850℃煅烧1.5-2.5h，冷却至室温，500-600r/min干法球磨20-30min，然后按照固液比1：4-7将球磨后的粉末加入到质量分数为25％的硫酸溶液中，水浴加热至65-75℃，保温浸泡1-2h，静置冷却后过滤，滤渣用水洗涤至中性，按照固液比1：3-6将洗涤后的滤渣加入到质量分数为20％的氢氧化钠溶液中，加热至60-70℃，保温浸泡2-3h，静置冷却后过滤，滤液通入二氧化碳气体至pH为8-9时，关闭二氧化碳，静置陈化3-4h，过滤，滤渣洗涤干净，烘干，640-680℃温煅烧2-3h，冷却至室温，待用；
(2)按照质量比1:5-8将步骤(1)制得的原料与固含量为20％的铝溶胶混合，充分搅拌均匀，再加入相当于浆料质量14-18％的聚乙烯醇和7-13％的六偏磷酸钠，800-900r/min干法球磨4-7min，然后在真空度为1-2Pa、温度为-80～-90℃的条件下冷冻干燥15-25h，再在空气气氛下以10-15℃/min的速率升温至1460-1490℃，保温2-3h，再以3-5℃/min的速率降温至760-820℃，保温4-5h，再以2-4℃/min的速率降温至380-440℃，保温6-7h，冷却至室温，得到耐火料；
(3)将山砂、钛酸盐片晶、膨胀蛭石、废弃粘土砖、煤渣混合均匀，粉碎，过50-70目筛后与步骤(2)制得的耐火料进行干混，混合6-8min，然后加入适量的水，并加入余下原料进行湿混，混合4-7min；
(4)将步骤(3)制得的混合料加入成型模具中压制成型，成型压力为18-24MPa，脱模后进行晒水养护，10-15h养护一次，养护10-15天，然后自然环养护即可。
本发明的有益效果：
(1)本发明通过从蛇纹石尾矿、粉煤灰提铝渣、硅钙渣、冶炼烟尘等原料中提取二氧化硅，然后配合铝溶胶进行冷冻干燥和高温煅烧，可以得到以莫来石为主要成分的耐火料，该耐火料加入到砖中，可以大大提高耐火砖的耐火性，使得耐火砖在高温下仍能保持优异的综合性能，同时实现了蛇纹石尾矿、粉煤灰提铝渣、硅钙渣、冶炼烟尘等固体废渣的再资源化利用，具有重要的经济效益和社会效益；
(2)本发明采用钛酸盐片晶作为增强剂，与山砂、膨胀蛭石、废弃粘土砖、煤渣等原料配合制成的耐火砖不仅具有较高的耐压强度和抗折强度，还具有优良的耐高温性、抗热震稳定性和抗开裂性，使用寿命长，应用范围广。
