Problems solved by technology

However, the glass fiber will inevitably fall off and be adsorbed to the side of the filter during packaging and transportation, so that the smoker may inhale the glass fiber into the body, which is harmful to health; at the same time, the carbonaceous heat source material coated with glass fiber requires additional processes to complete. This will inevitably reduce production efficiency and increase costs

Embodiment 1

[0029] 1. Mix 75g of carbon powder, 10g of sodium alginate, 8g of calcium carbonate, 1g of iron oxide, 6g of potassium carbonate and 70g of water, and send them into a twin-screw extruder for extrusion. The twin-screw parameters are set as follows: temperature settings for each zone 30, and water is passed to keep the temperature fluctuation between ±5°C, the screw speed is set at 150 rpm, and after drying, a carbonaceous heat source rod 2 containing seven triangular longitudinal flow channels 1 is obtained;

[0030] 2. Mix 10g sodium alginate, 30g calcium carbonate, 5g magnesium hydroxide, 18g ceramic powder, 30g magnesium oxide whiskers, 2g iron oxide, 5g smoke foam, 0.5g corn oil and 30g water and then extrude with a single screw Out, make cylinder 3.

[0031] 3. Introduce the carbon heat source rod 2 into the die of the flame retardant material extruder in step 2, draw the material out from the other end of the die, and obtain a carbon heat source wrapped by the flame reta...

Abstract

The invention discloses a carbonaceous heat source covered by a flame-retardant material. The carbonaceous heat source is composed of a carbonaceous heat source material which includes a plurality of triangular longitudinal runners therein and the flame-retardant material covering the periphery of the carbonaceous heat source material. By virtue of the flame-retardant covering layer, the problem that the carbonaceous heat source, when burnt, is easy to become fallen off is effectively avoided; and meanwhile, heat loss can be reduced to the greatest extent, and harm to human bodies in the case of the invasion of glass fibers when glass fibers and like heat-insulating materials are adopted to cover is avoided.

Description

1. Technical field [0001] The invention relates to a heat source material for cigarettes, in particular to a carbonaceous heat source covered by a flame-retardant material, and belongs to the field of new tobacco products. 2. Background technology [0002] Low-temperature heating cigarettes generally deliver satisfaction and tobacco aroma to consumers through heat-not-burn tobacco, which adapts and satisfies the physiological needs of consumers to a certain extent. It is heated at a low temperature (ideal temperature range 450-550°C), which can effectively and greatly reduce various harmful components in the flue gas. The way to achieve it is generally to physically separate the tobacco from the heat source material, so the heat source material is the core of its design. Among them, carbonaceous heat source materials have become one of the main heat sources for low-temperature cigarettes due to their advantages of safety, stability, speed, efficiency, and low price. In ord...
