Edible oil fire extinguishing agent

The invention provides an edible oil fire extinguishing agent. According to the technical scheme, mineral powder serves as a main component and is matched with a chemical fire extinguishing agent andinert gas components to act on a fire scene in a spraying mode; the mineral powder with specific granularity not only plays a covering role, but also has certain adsorbability to edible oil based on aporous structure of the mineral powder, so that a certain blocking and fire extinguishing effect is achieved microcosmically; in addition, heptafluoropropane with higher safety is adopted, and a better fire extinguishing effect can be achieved by utilizing gasification heat absorption of the heptafluoropropane while direct fire extinguishing is performed; moreover, mineral powder such as mullitepowder and silicon carbide is sprayed out under the entrainment of high-pressure gas such as tetrafluorodibromoethane and monochlorodifluoromethane, certain impact is formed on flames, and thus the fire extinguishing effect is
