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.

Embodiment Construction

[0018] A method for preparing mesoporous ceramics includes the following steps:

[0019] (1) Pore-forming agent modification treatment: Put the starch into an aqueous dopamine hydrochloride solution with 15 times its weight, a temperature of 75°C, and a pH of 8, and stir and mix at 400 rpm for 18 hours, and then increase the speed to 650 rpm / min, slowly add an equal volume of zinc nitrate aqueous solution with a temperature of 65°C and a concentration of 15g / L, stir and react for 45 minutes, and then stand for 3.5 hours, then add 2-methylimidazole equimolar to zinc nitrate, and microwave shaking for 12 hours After suction filtration, the product was washed 3 times with deionized water and then freeze-dried to obtain a pore former coated with an organometallic framework;

[0020] (2) Ingredients: According to the production requirements, the aggregate, the pore former coated with the organometallic framework, and the magnesite are mixed uniformly in a weight ratio of 100:5:0.1, and...

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...
