Porous ceramic and preparation method thereof
The invention relates to the technical field of porous ceramic preparation, in particular to porous ceramic and a preparation method thereof. The porous ceramic is prepared from raw materials including a component a, a foaming agent and water, the component a comprises 40 wt%-80 wt% of ceramic powder; 1 wt%-20 wt% of short fibers; 15 wt% to 35 wt% of ceramic precursor resin; 1 wt%-5 wt% of a catalyst; in the component a, the sum of the contents of the components is 100%, and the foaming agent comprises a surfactant, a binder and a dispersant. The short fiber composite nanowire multi-stage reinforced porous ceramic prepared by the method is uniform in pore size, uniform in pore distribution and high in mechanical strength.
本发明涉及多孔陶瓷制备技术领域，尤其涉及一种多孔陶瓷及其制备方法。所述多孔陶瓷由包括组分a、发泡剂和水的原料制备得到；所述组分a包括：陶瓷粉40wt％～80wt％；短纤维1wt％～20wt％；陶瓷前驱体树脂15wt％～35wt％；催化剂1wt％～5wt％；所述组分a中，上述各组分的含量之和为100％：所述发泡剂包括表面活性剂、粘结剂和分散剂。本发明制备的短纤维复合纳米线多级增强的多孔陶瓷孔径大小均一、气孔分布均匀，且机械强度高。
