Exterior wall external thermal insulation foamed ceramic with ultralow heat conductivity coefficient and preparation method of exterior wall external thermal insulation foamed ceramic
The invention relates to an outer wall external thermal insulation foamed ceramic with an ultralow heat conductivity coefficient and a preparation method thereof, and belongs to the technical field of thermal insulation materials. The preparation method of the outer wall external thermal insulation foamed ceramic with the ultralow heat conductivity coefficient comprises the following steps: (1) mixing boron carbide, iron oxide, fluorite, albite and potassium feldspar to obtain a mixture; (2) carrying out ball milling on the mixture to obtain mixed powder I; (3) uniformly stirring the mixed powder I and aluminum nitride powder to prepare a foaming agent; (4) ball-milling the solid waste raw material into solid waste powder; (5) mixing a foaming agent, the solid waste powder and water, and uniformly stirring to prepare mixed powder II; (6) pressing the mixed powder II into a green body; and (7) sintering the green body to obtain the foamed ceramic. The prepared foamed ceramic has the structural characteristic that small holes surround large holes, can take density, strength, heat conductivity coefficient and other indexes into consideration, meets the requirements of the national standard of foamed ceramic for external thermal insulation of exterior walls, and can be used for external thermal insulation of the exterior walls.
本发明涉及一种超低导热系数外墙外保温泡沫陶瓷及其制备方法，属于保温材料技术领域；所述超低导热系数外墙外保温泡沫陶瓷的制备方法，其步骤如下：(1)将碳化硼、氧化铁、萤石、钠长石、钾长石混合，得到混合料；(2)将混合料球磨成混合粉料I；(3)将混合粉料I与氮化铝粉搅拌均匀制成发泡剂；(4)将固废原料球磨成固废粉料；(5)将发泡剂、固废粉料和水混合，搅拌均匀制成混合粉料II；(6)将混合粉料II压制成坯体；(7)将坯体烧结，得到所述的泡沫陶瓷。本发明所制备的泡沫陶瓷具有小孔围绕大孔的结构特点，并且可兼顾密度、强度和导热系数等指标，满足《外墙外保温泡沫陶瓷》国标的要求，可用于外墙外保温。
