Porous aerogel material, preparation method thereof and electronic cigarette atomization core

Abstract

The invention belongs to the field of electronic cigarettes, and particularly relates to a porous aerogel material, a preparation method thereof and an electronic cigarette atomization core. The porous aerogel material provided by the invention is prepared by mixing silicon dioxide aerogel powder and pore-forming agent powder, pressing and heating, wherein the pore-forming agent powder comprises one or more of ammonium bicarbonate, ammonium oxalate and polymethyl methacrylate; the particle size of the pore-forming agent powder is larger than the pore diameter of the silicon dioxide aerogel powder. The porous aerogel material provided by the invention has the advantages of reasonable porosity, large specific surface area, small density and high temperature resistance through combination of nano micropores of the silicon dioxide aerogel and artificial pores. The atomization core of the electronic cigarette prepared from the material is smooth in tobacco tar supply, and can adjust the dryness and humidity of a local area, so that atomized smoke is finer and smoother; and moreover, the material has excellent temperature resistance and heat insulation performance, so that the safe use of equipment can be ensured, and peculiar smell spreading caused by high-temperature carbonization generated by over-fast local heating of the tobacco tar can be prevented.

Description

technical field [0001] The invention belongs to the field of electronic cigarettes, and in particular relates to a porous airgel material, a preparation method thereof, and an electronic cigarette core. Background technique [0002] At present, the global control over traditional tobacco products is increasing year by year, and people pay more attention to their own health, which makes new tobacco products receive more attention. Especially e-cigarettes, because they can reduce the release of harmful components, have gradually become an important development direction and research and development hotspot of new tobacco products. [0003] E-cigarettes are electronic products that mimic cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that is powered by a rechargeable lithium polymer battery to drive the atomizer. By heating the e-liquid in the oil tank, it turns nicotine into vapor for users to smoke. [0004] The electronic cigarette ...
