Flammable and fire-resistant carbonaceous heat source, method for preparing same and use thereof

A flammable and fire-resistant carbonaceous heat source, comprising flammable carbon, flame-retardant carbon and a binder, wherein,

• the flame-retardant carbon comprises graphite and an auxiliary carbon source, the binder comprises glutinous rice glue, and based on a total weight of the flammable and fire-resistant carbon heat source, a content of each of the flammable carbon, the flame-retardant carbon and the binder is 40-75 wt %, 10-45 wt % and 3-15 wt %;
• a maximum weight loss peak temperature of the flammable carbon is 250-549° C. as determined by thermogravimetric analysis, and a complete burnout temperature is lower than 650° C.;
• the flame-retardant carbon is carbonaceous materials with higher ignition points than that of the flammable carbon;
• a maximum weight loss peak temperature of the auxiliary carbon source in the flame-retardant carbon is 551-700° C. as determined by thermogravimetric analysis, and a complete burnout temperature is lower than 800° C.
