Gasification slag foaming ceramic and preparation method thereof
The invention belongs to the technical field of closed-cell foamed ceramics, and discloses a gasified slag foamed ceramic and a preparation method thereof, and the gasified slag foamed ceramic is prepared from the following raw materials in parts by weight: 30-65 parts of gasified slag, 5-25 parts of coal gangue, 20-30 parts of silica sand, 3-5 parts of a fluxing agent and 0.1-0.3 part of a foaming agent. The high-volume solid waste gasification slag is adopted as a main raw material, the coal gangue and the silica sand with specific contents are adopted to respectively fill up aluminum and silicon elements lacked in the gasification slag, the problem that the strength of a ceramic framework is not enough due to the fact that the content of SiO2 in the gasification slag is lower than 65% is solved, and the gasification slag, the fluxing agent and the foaming agent are sintered together to obtain the foamed ceramic. According to the invention, the closed-cell foamed ceramic is produced by using the high-volume gasified slag as the main raw material for the first time, so that various solid wastes such as the gasified slag and the coal gangue can be reasonably utilized, waste is turned into wealth, the economic utilization efficiency of the various solid wastes such as the gasified slag is improved, the harm can be turned into benefit, and the environment is improved; meanwhile, the foamed ceramic with excellent performance and wide application is prepared.
本发明属于闭孔发泡陶瓷技术领域，公开一种气化渣发泡陶瓷及其制备方法，所述气化渣发泡陶瓷由如下重量份的原料制备：气化渣30～65份、煤矸石5～25份、硅砂20～30份、助熔剂3～5份，发泡剂0.1～0.3份。本发明采用高掺量固体废气物气化渣为主要原料，并采用特定含量的煤矸石、硅砂分别填补了气化渣中缺少的铝、硅元素，克服了气化渣中的SiO2含量低于65％容易导致陶瓷骨架强度不够的问题，并与助熔剂和发泡剂一起烧结得到发泡陶瓷。本发明首次提出采用高掺量气化渣作为主要原料生产闭孔发泡陶瓷，既可以合理地利用气化渣、煤矸石等多种固体废弃物，变废为宝提高气化渣等多种固体废弃物的经济利用效率，又可以变害为利改善环境，同时制备了性能优越、用途广泛的发泡陶瓷。
