Problems solved by technology

[0004] However, the porous ceramic products currently on the market have low porosity and uneven distribution, and the e-liquid cannot be fully atomized, resulting in a small amount of smoke and poor taste, and its low thermal conductivity leads to a low heating rate of porous ceramics, thus This slows down the entire atomization speed of e-liquid, further affects the amount of smoke, and cannot meet the smoking frequency and taste of consumers. Therefore, the existing porous ceramic products can no longer meet the application requirements of e-cigarettes.

Abstract

The invention relates to the technical field of electronic cigarettes, in particular to a porous ceramic for an electronic cigarette device and a preparation method thereof. The porous ceramic is composed of 30%-65% of brown corundum, 10%-30% of silicon carbide, and 3% to 8% of sintering agent, 10% to 25% of pore forming agent and 10% to 30% of binder are prepared through the steps of mixing and banburying, granulation by granulator, injection molding, high temperature degreasing and high temperature firing. Compared with the prior art, the porous ceramics of the present invention have high porosity, uniform and stable distribution, and an open porosity of more than 55%, so that the e-liquid can be fully absorbed and atomized, and has a high thermal conductivity, which greatly improves Improve the atomization rate of e-liquid, increase the amount of smoke, and solve the problems of slow atomization speed and poor taste of e-liquid in the current market.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a porous ceramic for electronic cigarette devices and a preparation method thereof. Background technique [0002] With the development of society and the improvement of people's health awareness, consumers have put forward higher requirements for smoking safety. Because smoking is prone to dependence and addiction, it is very difficult to quit smoking in a short period of time. In order to meet the current market demand, electronic cigarettes have become the first choice for smokers to get rid of smoking addiction. [0003] As the heating element of electronic cigarette, the atomizer is one of the important components. When inhaling, it achieves the effect of "swallowing clouds and mist". With the development of technology, the carrier used to adsorb e-liquid in the atomizer mainly adopts inorganic non-metal porous ceramic material, which not only has strong adso...
