Preparation method of micro-porous ceramic heating part for atomizer

Abstract

The invention discloses a preparation method of a micro-porous ceramic heating part for an atomizer. The preparation method of the micro-porous ceramic heating part for the atomizer comprises the steps of: uniformly mixing raw materials to obtain a micro-porous green body, wherein according to the weight ratio, the raw materials include 50-85% of a skeleton material, 10-40% of a pore forming agent, 0.5-2% of a foaming agent and 10-35% of a binding agent; the granularity of the skeleton material is 20-100 mu m; the skeleton material comprises one of aluminium oxide, silicon carbide and quartz;and the pore forming agent comprises at least one of wood dust, graphite powder, wood flour, starch and plastic powder; performing overlying, wherein a first micro-porous briquette and a second micro-porous briquette are overlying and adhered; and a heating circuit is positioned in the middle and / or the surface of a micro-porous ceramic body; and performing sintering in a protective atmosphere environment, so that a heating part is obtained, wherein the sintering temperature is 1100-1600 DEG C. The heating part is 15-120 mu m in aperture and 35-60% in porosity; and the heating part is steady to head, good in liquid absorption effect and good in atomization effect.

Description

technical field [0001] The invention relates to a heating element of an electronic atomizer, in particular to a preparation method of a microporous ceramic heating element for an atomizer. Background technique [0002] The oil-storage electronic cigarette uses heat to vaporize (atomize) the oil through the heating element, and the smoke produced can be inhaled by the user. Among them, the heating element of the nebulizer needs to have better heating capacity and liquid absorption capacity. [0003] The specific process of the existing atomizer ceramic heating element is: the electric heating wire is pre-embedded in the powdery microporous ceramics, and then formed by hot die casting, and the powder material is pressed and formed. [0004] The powder is on the surface of the Mosuo heating element in the die-casting plate (most of the electric heating elements are metal materials), and the die-casting process must also give a certain high temperature; the surface of the heati...

AI Technical Summary

Problems solved by technology

[0004] The powder is on the surface of the Mosuo heating element in the die-casting plate (most of the electric heating elements are metal materials), and the die-casting process must also give a certain high temperature; the surface of the heating element is heated and eroded, and the surface of the electric heating wire is easily oxidized. The ability of the heating wire to generate heat is unstable

At the same time, the outer layer of the heating wire is obtained by die-casting, the ceramic micropores are blocked, and the micropore effect is not obvious, which also leads to the unstable ability of the heating wire to heat outward

Powder die-casting is compacted, ceramic micropores are blocked, and the micropore effect is not obvious, which affects the liquid absorption of the ceramic layer
