Composition for porous material as well as preparation method and application of composition

The invention discloses a composition for a porous material as well as a preparation method and application of the composition. The composition for the porous material is prepared from the following components in parts by weight: 20 to 40 parts of thermoplastic polymer and 60 to 80 parts of modified water-soluble inorganic powder, wherein the modified water-soluble inorganic powder is prepared from the following components in parts by weight: 100 parts of water-soluble inorganic powder, 0.5-3 parts of a coupling agent, 2-5 parts of a surfactant and 2-5 parts of a processing aid. Wherein the modified water-soluble inorganic powder has excellent deliquescence resistance, and the situation that the modified water-soluble inorganic powder cannot form an effective microporous structure in the subsequent phase separation process due to deliquescence in the mixing extrusion process is avoided; and meanwhile, good compatibility with a thermoplastic high polymer material is realized. 本发明公开了一种用于多孔材料的组合物及其制备方法和应用。本发明用于多
