Porous ceramic material, preparation method thereof and honeycomb ceramic heat accumulator
The invention relates to a porous ceramic material, a preparation method thereof and a honeycomb ceramic heat accumulator. The porous ceramic material comprises a porous ceramic matrix and a protective layer coating the porous ceramic matrix, and the mass fraction of the protective layer in the porous ceramic material is 25%-40%; the porous ceramic matrix comprises the following raw materials: talc, kaolin, a first additive, a second additive, a binder, a pore-forming agent, a first dispersant, a lubricant and water; the protective layer is prepared from the following raw materials: magnesium aluminum silicate, sol, metal salt, a second dispersing agent and water; the first additive comprises an aluminum source and/or a silicon source; the second additive comprises mullite whiskers and/or silicon carbide fibers; the metal salt comprises magnesium salt and/or aluminum salt; in the protective layer, the molar ratio of magnesium to aluminum to silicon is 1: (0.5-5): (0.5-4). The porous ceramic material provided by the invention has good heat storage performance and excellent thermal shock resistance, the breaking strength loss rate can be effectively reduced, and the service life is greatly prolonged.
本申请涉及一种多孔陶瓷材料及其制备方法和蜂窝陶瓷蓄热体。多孔陶瓷材料包括多孔陶瓷基体以及包覆所述多孔陶瓷基体的保护层，保护层在多孔陶瓷材料中的质量分数为25%~40%；多孔陶瓷基体的原料包括滑石、高岭土、第一添加剂、第二添加剂、粘结剂、造孔剂、第一分散剂、润滑剂和水；保护层的原料包括硅酸镁铝、溶胶、金属盐、第二分散剂和水；第一添加剂包括铝源和/或硅源；第二添加剂包括莫来石晶须和/或碳化硅纤维；金属盐包括镁盐和/或铝盐；保护层中，镁、铝和硅的摩尔比为1:(0.5~5):(0.5~4)。本申请提供的多孔陶瓷材料兼具良好的蓄热性能和优异的抗热震性，可有效地降低抗折强度损失率，并极大地延长使用寿命。
