Example Embodiment

[0023] Such as figure 1 As shown, the method for preparing microporous ceramics according to one embodiment can be used to make the atomizing core of an atomizer. The preparation method of the microporous ceramic includes the following steps:

[0024] Step S110: mixing the raw materials to form a mixture.

[0025] Specifically, the step of mixing the raw materials to form a mixture includes: mixing a dispersant, a binder, and a solvent to form a premixed liquid; mixing the raw materials with the premixed liquid to form a slurry; drying the slurry to obtain the mixed material.

[0026] Specifically, the dispersant is selected from at least one of sodium citrate, sodium acrylate and sodium stearate. The mass ratio of dispersant to solvent is 0.5:100 to 3:100.

[0027] Specifically, the binder is selected from at least one of methyl cellulose, polyvinyl alcohol, and polystyrene. The mass ratio of binder to solvent is 0.5:100 to 5:100.

[0028] The solvent is distilled water. It should...

Example Embodiment

[0058] Example 1

[0059] The preparation process of the microporous ceramic of this embodiment is as follows:

[0060] (1) According to Table 1, weigh each component according to mass percentage content (abbreviated as content in the table) to obtain raw materials. Among them, the median particle size of diatomaceous earth is 40 microns; the median particle size of fly ash is 40 microns; the median particle size of the sintering aid is 25 microns; the median particle size of the pore former is 20 microns.

[0061] (2) Mix the dispersant, binder and distilled water for 1.5 hours to form a premixed liquid; ball mill the raw materials and the premixed liquid to form a slurry, and the mass ratio of the raw material to the grinding medium is 1:2 when the ball mill is mixed. The mixing speed is 90 revolutions per minute, and the mixing time is 25 hours; the slurry is dried at 85° C. for 15 hours to obtain a mixture. Among them, the dispersant is sodium citrate; the mass ratio of the dis...

Abstract

The invention relates to micropore ceramic and a preparation method and an atomizing core thereof. The preparation method for the micropore ceramic comprises the following steps: mixing raw materialsto form a mixture, according to a mass percent, wherein the raw materials comprise 50%-70% of kieselguhr, 15%-25% of coal ash, 10%-20% of a sintering agent and 5%-10% of a pore-forming agent, and thesintering agent comprises aluminum oxide; enabling the mixture to be prepared as a blank body; and sintering the blank body, to obtain the micropore ceramic. The micropore ceramic prepared by the above method has the higher apparent porosity and the higher strength.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a microporous ceramic, a preparation method thereof and an atomizing core. Background technique [0002] At present, the electronic cigarette cores on the market are usually made of fibrous cotton liquid guiding rope wrapped around the heating element of the heating wire. The liquid guiding speed is slow. The area is small and the amount of smoke produced is also small. [0003] Microporous ceramics are widely used in electronic vaporizers because of their high porosity, good absorption, and good liquid storage, and the ceramics themselves are resistant to high temperatures and are not prone to burnt burns. However, the current microporous ceramics have the problems of low strength and low apparent porosity, which restrict the development of microporous ceramic atomizing cores. Contents of the invention [0004] Based on this, it is necessary to provide a method for preparing...
