Foaming ceramic with high fire endurance and preparation method thereof
The invention belongs to the technical field of foamed ceramics, and relates to a foamed ceramic with high fire endurance and a preparation method thereof, and the preparation method comprises the following steps: (1) mixing aluminum trifluoride and barium titanate to obtain mixed pellets; (2) carrying out ball milling on the mixture to obtain mixed powder I; (3) mixing aluminum nitride powder with the mixed powder I to prepare a composite foaming agent; (4) preparing solid waste raw materials; (5) adding a ceramic dispergator into the solid waste raw material, and ball-milling the solid waste raw material into solid waste powder; (6) uniformly mixing the composite foaming agent, the solid waste powder and water to prepare mixed powder II; (7) pressing the mixed powder II into a green body; and (8) sintering the green body to obtain the foamed ceramic. The fire resistance limit of the foamed ceramic prepared by the invention is far higher than the first-grade fire resistance grade requirement of a non-bearing outer wall, and meanwhile, the first-grade fire resistance grade requirement of a firewall is also met. In addition, under the condition that the density is equivalent, the foamed ceramic has higher compressive strength.
本发明属于发泡陶瓷技术领域,涉及一种具有高耐火极限的发泡陶瓷及其制备方法,包括如下步骤:(1)将三氟化铝和钛酸钡混合,得到混合料球;(2)将混合料球磨成混合粉料I;(3)将氮化铝粉与混合粉料I混合,制成复合发泡剂;(4)配制固废原料;(5)向固废原料中加入陶瓷解胶剂后,将固废原料球磨成固废粉料;(6)将复合发泡剂、固废粉料和水混合均匀,制成混合粉料II;(7)将混合粉料II压制成坯体;(8)将坯体进行烧结,得到所述的发泡陶瓷。本发明制备的泡沫陶瓷的耐火极限远高于非承重外墙的一级耐火等级要求,同时也满足防火墙的一级耐火等级要求。此外,在密度相当的情况下,本发明的发泡陶瓷具有更高的抗压强度。
