Abstract

The invention discloses a porous ceramic atomizing core and a preparation method thereof. The porous ceramic atomization core is composed of a mixture and a molten material, wherein the mixture comprises: 40%-69% of diatomite, 20%-35% of low-temperature glass powder, 10%-20% of a pore-forming agent and 1%-2% of vermiculite and / or perlite; and the molten material comprises paraffin accounting for 40%-50% of the mass of the mixture and beewax accounting for 5%-10% of the mass of the mixture. The preparation method of the porous ceramic atomization core comprises the steps of material mixing, blank making and sintering. The porous ceramic atomization core material and the oil guide rod are integrally roasted and formed, so that the production efficiency is remarkably improved, the technological process is simple, the cost is low, the prepared porous ceramic atomization core is extremely high in size stability, the atomization core is tightly attached to the oil guide rod, and the oil leakage phenomenon cannot occur.

Description

technical field [0001] The invention belongs to the field of ceramic materials, and in particular relates to a porous ceramic atomizing core and a preparation method thereof. Background technique [0002] Porous ceramics are widely used in the field of vaping cores due to their high porosity, good oil storage, high oil absorption, and high temperature resistance, which are not suitable for burning. The electronic cigarette heating and vaporizing module is the core component of the electronic cigarette, usually including the oil guide rod and the atomizing core. At present, the method of producing the heating and vaporization module is to roast the atomizing core first, then wrap cotton cloth around the atomizing core, and then insert the atomizing core into the oil guide rod. This production process has low efficiency, and the oil guide rod and There will be gaps between the atomizing cores, resulting in oil leakage during use, which seriously affects the taste of electroni...
