Method for preparing cigarette filamentary carbon heat source material by ethanol

Abstract

The invention discloses a method for preparing a cigarette filamentary carbon heat source material by ethanol. The method comprises the following steps of mixing sodium alga acid or ammonium alginate or potassium alginate with carbon powder and water, and blending into jelly, wherein the mass ratio of the sodium alga acid or ammonium alginate or potassium alginate to the carbon powder is 1 to (5-45); then extruding the jelly into a filament, enabling the filament to fully contact ethanol of which the mass concentration is greater than or equal to 66% to obtain condensate; rinsing and drying the condensate, so that the moisture content achieves 10-20%, so as to obtain the cigarette filamentary carbon heat source material. By adopting the method, not only can the damage caused by a glass fiber absorbed into a human body be reduced, but also the combustibility of the carbon heat source is also improved; and the method has the characteristics that the method is simple in method, short in production period, low in cost and the like.

Description

technical field [0001] The invention relates to the field of cigarettes, in particular to a method for using ethanol to prepare filamentous carbonaceous heat sources for cigarettes used in low-temperature cigarettes. Background technique [0002] Studies have shown that nicotine and most tobacco flavor components can be transferred to smoke at lower temperatures (300-500°C). If the temperature of the cigarette is lowered to below 600°C (the ignition point of tobacco is about 700°C), various harmful components of the smoke can be greatly reduced, while the aroma components are relatively less affected. Therefore, a cigarette that uses a carbonaceous heat source for dry distillation of tobacco components was invented. Among them, the carbonaceous heat source of R.J. Reynolds Tobacco’s Eclipse cigarette uses glass fiber wrapped carbon rods. However, the carbon rods are formed by extrusion. , the interior is dense, and in order to form hot air flow, the outer layer needs to be ...

Therefore, a cigarette that uses a carbonaceous heat source for dry distillation of tobacco components was invented. Among them, the carbonaceous heat source of R.J. Reynolds Tobacco’s Eclipse cigarette uses glass fiber wrapped carbon rods. However, the carbon rods are formed by extrusion. , the interior is dense, and in order to form hot air flow, the outer layer needs to be wrapped with breathable glass fiber. Some studies believe that even if such particles can be trapped by the filter material, they will inevitably be adsorbed on the filter during packaging and other processes, resulting in inhalation and harm. Healthy, dense carbon rods are also harder to ignite than thinner carbon filaments
