Foamed ceramic thermal insulation material and preparation method thereof
The invention belongs to the technical field of building materials, and provides a foamed ceramic thermal insulation material which comprises the following components in parts by mass: 30-90 parts of coal gangue, 4-64 parts of potassium feldspar, 2-6 parts of a fluxing agent and 0.5-3 parts of a foaming agent. The coal gangue is used as a main raw material, and the potassium feldspar and the fluxing agent which have a fluxing effect are added, so that the melting temperature is reduced, and the firing temperature of the foamed ceramic thermal insulation material is reduced; moreover, by controlling the dosage of the fluxing agent and the foaming agent, the viscosity of an enamel liquid phase generated in the firing process is matched with the gas production rate of the foaming agent, the foaming effect of the foaming agent is fully exerted, and the uniformity of pores in the material is ensured, so that the foamed ceramic thermal insulation material with excellent performance is obtained. A result of the embodiment shows that the volume density of the foamed ceramic thermal insulation material provided by the invention is 193.0 kg/m < 3 >, the heat conductivity coefficient is 0.07 w/(m.k), and the firing temperature is 850 DEG C.
本发明属于建筑材料技术领域,提供了一种发泡陶瓷保温材料,按质量份数计,包括如下组分:煤矸石30~90份,钾长石4~64份,助熔剂2~6份,发泡剂0.5~3份。本发明以煤矸石为主要原料,并添加具有助熔作用的钾长石和助熔剂,降低了熔融温度,从而降低了发泡陶瓷保温材料的烧制温度;并且,通过控制助熔剂和发泡剂的用量,使得烧制过程中生成的釉质液相的粘度与发泡剂的产气速率相匹配,充分发挥了发泡剂的发泡效果,保证了材料中气孔的均匀性,从而得到了性能优良的发泡陶瓷保温材料。实施例的结果显示,本发明提供的发泡陶瓷保温材料的体积密度为193.0kg/m3,导热系数为0.07w/(m·k),烧制温度为850℃。
