Thermal insulation foamed ceramic material based on solid waste material and preparation method and application thereof
The invention belongs to the technical field of thermal insulation materials, and provides a thermal insulation foamed ceramic material based on a solid waste material and a preparation method and application thereof. The thermal insulation foamed ceramic material comprises 60-70 parts of silicon-containing aluminum tailings, 15-20 parts of dolomite tailings, 15-25 parts of coal gangue, 15-25 parts of kaolin, 0.3-1.2 parts of a composite foaming agent, 0.1-1 part of a dispersant and 1-3 parts of sepiolite. The silicon-containing aluminum tailings comprise iron tailings, tungsten tailings and expanded perlite tailings. By reasonably selecting the types of the solid waste raw materials and the foaming agent, controlling the dosage and particle size of the solid waste raw materials and the foaming agent and reasonably controlling the roasting temperature and time, the internal structure of the obtained ceramic is tiny closed pores and is uniformly distributed, and the ceramic insulation board is low in heat conductivity coefficient, low in water absorption rate, high in strength, small in volume density and good in durability; the method can be used for prefabricated parts such as building external wallboards, internal wallboards and interlayer insulation boards.
本发明属于保温材料技术领域，提供了一种基于固废材料的保温发泡陶瓷材料及其制备方法和应用。本发明的保温发泡陶瓷材料包含含硅铝尾矿60～70份、白云石尾矿15～20份、煤矸石15～25份、高岭土15～25份、复合发泡剂0.3～1.2份、分散剂0.1～1份、海泡石1～3份；含硅铝尾矿包含铁尾矿、钨尾矿和膨胀珍珠岩尾矿。本发明通过合理选择固废原料和发泡剂种类，控制各固废原料和发泡剂的用量及粒径，合理控制焙烧温度和时间，得到的陶瓷内部结构为微小的闭气孔且分布均匀，陶瓷保温板的导热系数低、吸水率低、强度高、体积密度小、耐久性好；能够用于建筑外墙板、内墙板、夹层保温板等预制构件。
