Foamed ceramic prepared by using granite saw mud as base material and preparation method thereof
The invention relates to a foamed ceramic prepared by using granite saw mud as a base material and a preparation method thereof, the foamed ceramic is formed by stacking and sintering a plurality of sheets, the base materials of the sheets are granite saw mud, a foam stabilizer containing alumina and a lightweight filler, a sheet binder is arranged between the sheets, and the sheet binder comprises crushed crude pearlite. The foamed ceramic is subjected to high-temperature foaming in a multi-sheet stacked firing manner, mutual reaction among the sheets is promoted through the green body binding agent, and the specific gravity of the green body is reduced through the light filler so that the foaming expansion rate of the foamed ceramic is reduced; and the foam stabilizer is utilized to enable the foamed ceramic to uniformly expand and keep a certain shape in the foaming process, so that collapse caused by huge deformation of the foamed ceramic green body in the foaming process is prevented, and high-temperature foaming of the foamed ceramic under the condition of no mold frame is met.
一种利用花岗岩锯泥为基料制备的发泡陶瓷以及制备方法，所述发泡陶瓷由若干薄片叠烧而成，所述薄片的基料为花岗岩锯泥、含有氧化铝的稳泡剂以及轻质填充剂，在各薄片之间设置有薄片结合剂，所述薄片结合剂包括珍珠岩粉。本申请的发泡陶瓷采用多片叠烧方式进行高温发泡，薄片与薄片之间通过坯体结合剂促进薄片间相互反应，并且通过轻质填充剂降低生坯体比重使发泡陶瓷发泡膨胀率减小，并利用稳泡剂使发泡陶瓷在发泡过程中能够均匀膨胀并保持一定的形状，防止发泡陶瓷坯体在发泡过程中产生巨大变形而塌陷，满足发泡陶瓷在无模框条件下高温发泡。
