Abstract:
A porous material and preparation method thereof is provided. The material includes a material body. The body consists of pore cavities classified according to pore size of material and cavity walls surrounding to form the pore cavities. The lower-level pore cavities are arranged on the cavity walls of the upper-level pore cavities framed by surrounding a three-dimensional space. All the pore cavities are interconnected. The preparation method is: mixing raw powders with pore-forming agent for the smallest-level pore cavities of porous material to formulate slurry; uniformly filling the slurry into polymer material support to form green body and get dried and smashed to obtain mixed grains; uniformly mixing the mixed grains with pore-forming agent for upper-level pore cavities greater than the smallest-level pore cavities of porous material to make compact green body; performing vacuum sintering; performing the conventional follow-up treatment according to the raw materials process of porous material.

Claim (Index 14):
A method for preparing a porous material, comprising the following steps:\n mixing raw material powder with a pore-forming agent for preparing smallest-level pore cavities of the porous material and formulating a slurry, wherein the slurry is uniformly filled into a polymer material support to form a green body and is dried and smashed to obtain mixed grains containing the raw material, the pore-forming agent and a material of the polymer material support; uniformly mixing the mixed grains above with a pore-forming agent for preparing, upper-level pore cavities which are larger than the smallest-level pore cavities of the porous material to make a compact green body; performing vacuum sintering to the compact green body, wherein the sintered green body is subjected to a conventional follow-up treatment according to a raw material process of the porous material to obtain the porous material; wherein the porous material comprises a material body, wherein the material body is composed of pore cavities classified according to a. pore size of the material; and cavity walls surrounding to form the pore cavities; wherein the cavity walls of upper-level pore cavities are arranged with lower-level pore cavities, the upper-level pore cavities are formed by surrounding a three-dimensional space are arranged with lower-level pore cavities: the pore cavities of a same level at all levels are connected to each other, and the pore cavities among different levels are connected with each other.
