Abstract

The invention discloses porous ceramic for an electronic cigarette atomization core with low thermal conductivity and high porosity and a preparation method of the porous ceramic, and particularly relates to the field of ceramic materials. Raw materials used in the invention comprise, by mass, 1%-15% of mullite, 40%-60% of diatomite, 5%-25% of alumina hollow spheres, 1%-5% of foamy carbon powder, 10%-15% of a pore-forming agent, 1%-8% of an inorganic binder and 0.1%-0.5% of a retarder. The diatomite, mullite and dense foam carbon in the raw materials are of a porous structure, the aluminum oxide hollow spheres are of a hollow structure, the pore-forming agent can be used for forming pores in the porous ceramic, meanwhile, mullite can also play a role of aggregate, and through reasonable matching according to the proportion, the prepared porous ceramic atomizing core has relatively low thermal conductivity and relatively high apparent porosity.

Description

technical field [0001] The embodiments of the present invention relate to the field of ceramic materials, and in particular relate to porous ceramics for a low-thermal-conductivity high-porosity electronic cigarette atomizing core and a preparation method thereof. Background technique [0002] Porous ceramics are widely used in electronic vaporizers because of their high porosity, good oil absorption, and good liquid storage properties, and the ceramics themselves are resistant to high temperatures and are not prone to burnt burns. However, the ceramic atomizing cores of electronic cigarettes currently on the market are small in size. During the continuous smoking process, the heating time of the ceramic atomizing cores is long and the time interval is short. There are still ceramic atomizing cores on the market because the thermal conductivity of the atomizing cores is too high. Therefore, it is urgent to develop a porous ceramic material with high porosity and low thermal ...
