Description
技术领域
本发明涉及耐火材料技术领域，尤其是涉及一种抗裂镁碳砖及其制备方法。
背景技术
镁碳砖因具有良好的抗热震性和抗渣侵蚀性，所以被广泛应用于钢铁冶金工业。由于碳易氧化引起制品强度降低，抗侵蚀能力下降，使镁碳砖丧失优势。为提高镁碳砖在高温条件下的抗氧化能力，关键在于控制材料的脱碳速度。目前常用的一种方法是在镁碳砖中添加防止氧化的添加剂，常见的添加剂主要有两类，(1)金属或合金细粉；(2)非金属细粉。
例如，申请公布号CN101747065A，申请公布日2010.06.23的中国专利公开了一种镁碳砖，该镁碳砖的原料由30-80重量份废弃镁碳砖颗粒，3-40重量份镁砂颗粒，6-12重量份石墨，5-15重量份镁砂粉，3-15重量份微粉添加剂，2.2-3.5重量份有机结合剂组成。该镁碳砖中添加微粉添加剂(高温沥青粉、氧化铝微粉、金属铝粉、金属硅粉、金属镁粉、氮化硼粉、碳化硅粉中的任意一种或一种以上)以提高镁碳砖在高温下的抗氧化能力，其存在以下不足：(1)金属微粉(如金属铝粉、金属硅粉等)易发生氧化，已氧化的金属与镁砂和石墨中的杂质易发生不利的反应，氧化时会起熔剂的作用，众所周知，在烧成镁砖中，氧化铝与高钙硅比的硅酸盐矿物能发生反应形成液相，会对耐火度产生明显的影响，在钢水、熔渣和气体的侵蚀作用下，很容易导致制品使用寿命降低；另外该镁碳砖在生产过程中，添加的金属微粉会造成镁碳砖热膨胀过高，从而产生很高的应力，导致镁碳砖极易开裂；而非金属微粉(如氮化硼粉、碳化硅粉等)的加入又会影响镁碳砖的抗渣性；(2)在镁碳砖的制备过程中，易产生层裂、韧性差。
发明内容
本发明是为了解决现有技术的镁碳砖所存在的上述技术问题，提供了一种配方合理科学，能有效避免砖体层裂，提高使用寿命，砖体质量和性能佳的抗裂镁碳砖。
本发明还提供了一种抗裂镁碳砖制备方法，工艺步骤简单，可操作性强，成本低，适合工业化生产。
为了实现上述目的，本发明采用以下技术方案：
本发明的一种抗裂镁碳砖，所述抗裂镁碳砖由以下重量份的组分制成：75～80份镁砂，7～10份玄武岩颗粒，5～10份五水硫酸铜，0.3～0.5份六亚甲基四胺，15～18份石墨，3～5份陶瓷颗粒Al4SiC4，3～5份结合剂。本发明针对现有镁碳砖配方所存在的缺陷，对其进行了重新优化改进，尤其是添加了玄武岩颗粒、五水硫酸铜及陶瓷颗粒Al4SiC4，其中玄武岩颗粒能使砖体上形成的裂纹发生偏移和分岔，抑制长裂纹产生并改变方向，同时阻止砖体内裂纹的扩散，从能有效提高镁碳砖的抗热震性，五水硫酸铜中的结合水在高温条件下失去后，体积减小，使得硫酸铜周围产生微小空间，该空间可有效抵消镁碳砖的热膨胀，降低内应力，从而有效避免镁碳砖开裂，陶瓷颗粒Al4SiC4相对于常规添加剂(如金属铝粉、金属硅粉等)，其能还原被氧化的碳，同时将自身的碳作为游离碳加入到镁碳砖中补充碳源，另外Al4SiC4分解生成的Al2O3、SiC与MgO反应最终生成镁铝尖晶石和镁橄榄石在砖体表面形成保护层以防止进一步氧化，能大大降低碳损失量，提高镁碳砖的抗渣性，能提高其使用寿命。
作为优选，所述镁砂由以下重量份的不同粒径镁砂混合而成：20～25份3～5mm的镁砂，25～30份1～2mm的镁砂，10～15份0.3～0.5mm的镁砂，5～8份0.05～0.08mm的镁砂。镁砂的粒度分布非常关键，小粒径的颗粒的比表面积较大，在加入时会带人更多的空气，使层裂的产生几率增加；而作为骨架材料的大粒径颗粒较少同样也会造成层裂，因此本发明通过严格控制镁砂颗粒的粒度范围和加入量，从而保证压制出密实的产品，有效防止层裂的产生。
作为优选，所述玄武岩颗粒的粒径为20～25mm。玄武岩颗粒的粒径过大，反而会增加砖体的裂纹，粒径过小，则效果不显著，因此本发明中限定玄武岩颗粒的粒径为20～25mm。
作为优选，所述陶瓷颗粒Al4SiC4通过以下方法制得：将铝粉、硅粉、碳粉按摩尔比4:1:4混合后，在氮气保护下加酒精于球磨机中球磨至少24h，在真空热压烧结炉中于1600～1800℃下烧结2～3h，冷却后研磨，即得陶瓷颗粒Al4SiC4。
作为优选，所述陶瓷颗粒Al4SiC4的粒径为5～10μm。
作为优选，所述结合剂为改性酚醛树脂，所述改性酚醛树脂通过以下方法制得：
(a)将萘磺酸盐甲醛缩聚物溶于乙醇中形成质量百分比浓度为0.5～1％的混合溶液。
(b)在混合溶液中加入为混合溶液质量1～1.5％的纳米二氧化硅，超声分散，得分散液，待用。二氧化硅分散后极易团聚，其分散性一直是本领域的技术难点，本发明中的萘磺酸钠甲醛缩合物可吸附在纳米二氧化硅界面上，使纳米二氧化硅界面带电，并产生ζ电位，分散的纳米二氧化硅相互靠近时，由于双电层的静电排斥而分离，从而维持其分散稳定性，使其不易团聚，本发明通过超声和萘磺酸钠甲醛缩合物有效解决了纳米二氧化硅不易分散的问题。
(c)按n(苯酚)：n(甲醛)＝1：1.25～1.32，将苯酚溶于甲醛溶液中，得预混液。
(d)按v(分散液)：v(预混液)＝1:5～6，边搅拌边在预混液中加入分散液，再按n(苯酚)：n(氢氧化钠)＝1：1.25～1.32，边搅拌边滴加入氢氧化钠溶液，得反应液。
(d)将反应液用油浴进行加热，加热搅拌至50℃后，控制升温速率为0.5～0.6℃/min，至温度为90～95℃后，恒温反应2～3h，加酸中和至pH为6.5～7.0，真空脱水后加入产物0.5～1倍体积的乙二醇，得改性酚醛树脂。目前在镁碳砖中仍广泛采用酚醛树脂作为粘合剂，但其热分解温度和抗氧化能力较差，因此已经不能满足新型耐火材料的使用，本发明中以二氧化硅对酚醛树脂进行了改性，使无机纳米二氧化硅与酚醛树脂的表面性能相匹配，提高二者的相容性、湿润性和粘结性，并有效改善了酚醛树脂的热分解温度和抗氧化能力(热分解温度可提高大约190℃，碳氧化温度可提高大约1200℃)，还能提高镁碳砖的强度，拓宽了其应用领域。
一种抗裂镁碳砖制备方法，具体步骤为：按配比将各原料混合后加入混砂机中进行混炼，混炼后加入钢模中压制成型得砖坯，最后对砖坯干燥后即得抗裂镁碳砖。
作为优选，混炼时间为40～50min，成型压力为100～120Mpa，干燥温度为200～250℃，干燥时间为22～24h。
因此，本发明具有如下有益效果：
(1)本发明针对现有镁碳砖配方所存在的缺陷，对其进行了重新优化改进，尤其是添加了玄武岩颗粒、五水硫酸铜及陶瓷颗粒Al4SiC4，并对镁砂的粒度分布进行了调整，能有效避免砖体层裂，大大降低碳损失量，提高镁碳砖的抗渣性和抗氧化性能，提高了使用寿命，砖体质量和性能佳；
(2)提供了一种抗裂镁碳砖制备方法，工艺步骤简单，可操作性强，对设备无特殊要求，制备成本低，适合工业化生产。
