A kind of preparation method of mesoporous ceramic

Abstract

The invention discloses a preparation method of mesoporous ceramic. The mesoporous ceramic is prepared by taking a traditional pore-forming agent clad with an organic metal framework compound as a novel ceramic pore-forming agent, wherein the organic metal framework compound is a coordination polymer, has a three-dimension porous structure and is a high-stability mesoporous material taking metal ions as connection points; meanwhile, the surface of the traditional pore-forming agent is subjected to polydopamine membrane cladding treatment to improve the complexation of the metal ions on the surface of the traditional pore-forming agent, thereby realizing the high-efficient cladding of the organic metal framework compound. The novel pore-forming agent has good pore-forming capability equal to that of the traditional pore-forming agent, and also endows traditional ceramic pores with multidimensional mesoporous structures, the micropore performance of ceramic is obviously improved, and a prepared ceramic product is higher in porosity and more uniform; in addition, the metal ions can be converted into metal or metal compounds in a sintering process, so as to further improve the comprehensive performance of a ceramic body.

Description

Technical field [0001] The invention relates to the technical field of ceramics, in particular to a method for preparing mesoporous ceramics. Background technique [0002] With the progress of society, many reasons such as the emission of industrial hazardous substances and gases, decoration, oil fume, etc., make it inevitable to produce hazardous substances and gases in family rooms, causing air pollution and seriously endangering people's health. Consumers' awareness of environmental protection has gradually Therefore, the development of healthy and environmentally friendly building materials is inevitable. Ceramic tile, as a very common building decoration material, has a wide range of products, but the homogeneity is serious, the function is single, and it lacks market competitiveness. [0003] As we all know, porous materials have good adsorption capacity and a certain ability to purify air. From the cheap activated carbon adsorption material to the expensive air purifier, th...

Problems solved by technology

At present, when preparing porous ceramics, more consideration is given to how to increase the porosity, but the influence of the pore-forming agent on the mud and sintering temperature is not considered, resulting in the uneven distribution of pore structures in many products, which restricts the improvement of the comprehensive performance of porous ceramics.
