Lightweight high-strength heat-insulating ceramic with layered nano-pore structure and preparation method thereof
The invention discloses a preparation method of light-weight high-strength heat-insulating ceramic with a layered nanopore structure, which comprises the following steps: mixing inorganic micro/nano sheets, an inorganic sintering aid and an organic matter solution to obtain dispersion liquid slurry, preparing the slurry into a composite film with a layered structure by a specific solution film casting method, laminating the obtained film, and sintering to obtain the light-weight high-strength heat-insulating ceramic with the layered nanopore structure. A series of light-weight high-strength heat-insulating ceramics with layered nano-pore structures are obtained. According to the method disclosed by the invention, simple preparation of the light-weight high-strength heat-insulating ceramic with the large-size layered nano-pore structure can be efficiently realized. Moreover, the method is universal, economical, simple and easy to implement, and a plurality of inorganic nano/micron sheets can be assembled into the ceramic material with the layered nano-pore structure; the prepared porous ceramic has excellent heat-insulating property and mechanical strength, has the characteristics of in-plane and out-plane heat-conducting property anisotropy, and can realize directional conduction of heat and avoid local heat concentration.
