Description

一种环保墙体砖
技术领域
本发明涉及环境保护领域，具体涉及一种环保砖。
背景技术
粘土是传统墙体砖的主要原料，但是大量的使用粘土势必会导致自然环境的破坏，而随着社会经济的不断发展，砖的需求量逐步增大，现有的粘土资源已经不能再满足制砖的需求，加之我国对于环境保护的不断加强。因此，研发一种使用其他原料代替粘土、具有较高性能的环保砖成为了急需解决的问题。
发明内容
本发明通过调整砖体的原料组成，一方面使用了高岭土尾矿粉、煤矸石粉、膨润土粉和红柱石等作为主要原料，同时添加了纳米氧化铝、纳米氧化镁、纳米二氧化钛等成分，既实现了环保，又保证了砖体具有较好的性能特性。
具体涉及一种环保墙体砖，其特征在于按重量份其原料组成如下：高岭土尾矿粉20-35份、煤矸石粉20-40份、膨润土粉15-20粉、红柱石粉10-20份、纳米氧化铝7-9份、纳米氧化镁1-5份、纳米二氧化钛5-8份、硅微粉3-5份、氧化锆粉1-5份、氮化硼粉3-5份、石墨粉5-8份、碳化硅粉5-8份、氧化铈粉6-9份、氧化铬粉3-5份、不锈钢纤维3-5份。
本发明环保砖制备工艺简便：按照规定称量原料，混合后进行球磨处理；球磨后加入适量水，得到料浆；将料浆制坯成型；随后进行干燥和烧制处理。
本发明具有以下优势和效果：
1、采用了高岭土尾矿粉、煤矸石粉、膨润土粉和红柱石等作为主要原料，原料来源广泛，尤其对于使用高岭土尾矿粉和煤矸石粉，实现了对于废弃物的再利用。
2、通过添加纳米氧化铝、纳米氧化镁、纳米二氧化钛和硅微粉等原料，通过合理配备其含量，提高了原料间的反应活性，由此一方面可以提高原料中高岭土尾矿粉、煤矸石粉等底活性原料的用量，同时还可以在较低的烧成温度下使砖体获得较高的强度等特性，本发明砖体制备时烧结温度仅需1000℃以下即可。
3、通过添加氧化锆粉、氮化硼粉、石墨粉、碳化硅粉等原料，通过合理配置其含量，提高了砖体的耐磨性、抗热震性等特性。
4、通过各类原料种类及含量的合适选择配比，本发明的环保砖可以达到如下性能指标：常温强度≥230MPa、热震稳定性(1100℃水冷)≥11次、显气孔率≤12％、莫氏硬度≥8。
