Problems solved by technology

Because of the rapid heating rate of the heating wire and low heating delay, there will be no atomization delay during the entire 1-3 second pumping process, but at the same time, the temperature is not easy to control, and it is easy to coke the e-cigarette liquid. It affects the taste, and secondly, long-term use will cause the metal components of the heating wire to migrate, enter the smoke and be sucked, affecting health
As an environmentally friendly heating ceramic material that replaces the heating wire, in the known electronic cigarette technology field, most of the heating ceramics provided have a high temperature coefficient of resistance, so there is a serious heating delay phenomenon, which often leads to 1- During the 3-second puff, especially the first puff, no smoke is produced

Abstract

The invention provides heating ceramic slurry, comprising a composite functional phase, an inorganic additive and an organic support. The composite functional phase includes a main functional phase and a TCR (temperature coefficient of resistance) adjusting phase. The main functional phase includes, but not limited to, one of or mixture of any of tungsten powder, molybdenum powder, manganese powder, silver powder, copper powder, nickel power, cobalt powder, titanium powder, chromium powder, and zinc powder; the TCR adjusting phase includes, but not limited to, one of or mixture of any of platinum powder, ruthenium powder, palladium powder, rhodium powder, osmium powder, iridium powder, germanium powder, and lanthanum powder or their oxides; the TCR adjusting phase accounts for 0.1-10% by weight of the main functional phase so that TCR of the heating ceramic slurry is kept to 1500 ppm / DEG C to 4000 ppm / DEG C. The heating ceramic slurry has low temperature coefficient of resistance and has delayed heating.

Description

technical field [0001] The invention relates to the technical field of novel tobacco products, in particular to a heating ceramic slurry and a preparation method thereof. Background technique [0002] Existing electronic cigarette atomizers atomize electronic cigarette liquid by winding glass fiber cotton with a heating wire, thereby generating smoke for consumers to inhale. Because of the rapid heating rate of the heating wire and low heating delay, there will be no atomization delay during the entire 1-3 second pumping process, but at the same time, the temperature is not easy to control, and it is easy to coke the e-cigarette liquid. It affects the taste, and secondly, long-term use will cause the metal components of the heating wire to migrate, enter the smoke and be inhaled, affecting health. As an environmentally friendly heating ceramic material that replaces the heating wire, in the known electronic cigarette technology field, most of the heating ceramics provided h...
