Low-density microcellular foaming ceramic based on waste refractory material and manufacturing method thereof
The invention discloses a low-density microcellular foamed ceramic based on waste refractory materials and a manufacturing method thereof, and belongs to the technical field of porous ceramic material preparation, a blank comprises the following components: 0.1-1 part of a carbonaceous waste refractory material, 20-40 parts of a feldspar solid waste material, 0.1-0.2 part of a dispersant and 1-6 parts of a passivated aluminum-silicon waste refractory material. After being passivated, the aluminum-silicon waste refractory material is doped into the foamed ceramic, and the high-temperature-resistant crystal phase composition of the aluminum-silicon waste refractory material can stably exist in a molten green body, so that the stability of pores in the foaming stage is promoted; the low-temperature degradation impurities of the carbon waste refractory material are few, and the carbon waste refractory material can be oxidized and decomposed to generate gas after being concentrated at high-temperature heat preservation, so that uniform closed pores can be formed; the main raw materials used in the invention are industrial solid wastes and waste refractory materials, which not only contributes to green development of foamed ceramics, but also contributes to environmental protection and sustainable development of solid waste enterprises.
本发明公开了一种基于废弃耐火材料的低密度微孔发泡陶瓷及其制作方法，属于多孔陶瓷材料制备技术领域，坯料的成分包括碳质废弃耐火材料0.1份~1份、长石质固废材料20份~40份、分散剂0.1份~0.2份以及经过钝化的铝硅质废弃耐火材料1份~6份。铝硅质废弃耐火材料经过钝化后掺入发泡陶瓷中，其耐高温的晶相组成可稳定存在于熔融的坯体内，促进发泡阶段气孔的稳定；并且碳质废弃耐火材料低温降解杂质少，会集中在高温保温时才氧化分解并产生气体，能够形成均匀闭气孔；本发明使用的主要原材料为工业固废和废弃耐火材料，不仅有助于发泡陶瓷绿色化发展，且有助于环境保护和固废企业的可持续发展。
