Abstract

Embodiments provide a flammable and fire-resistant carbonaceous heat source and a method and a use for the same. In the embodiments, the flammable and fire-resistant carbonaceous heat source of the present disclosure includes flammable carbon, flame-retardant carbon and a binder, wherein, the flame-retardant carbon includes graphite, the binder includes glutinous rice glue, and based on a total weight of the flammable and fire-resistant carbon heat source, a content of the flammable carbon, the flame-retardant carbon and the binder is 40-75 wt %, 10-45 wt % and 3-15 wt %, respectively. The method for preparing the flammable and fire-resistant carbonaceous heat source of the present disclosure includes the following steps: mixing the flammable carbon, the flame-retardant carbon, and the binder in a content ratio; extruding and shaping a resulting mixture; and drying a resulting mixture.
