The invention relates to a powder fire extinguishing agent with cooling, flame-retardant and heat-insulating functions and a preparation method thereof, and belongs to the field of new energy safety. The powder fire extinguishing agent is mainly composed of a fire extinguishing main agent, a flame retardant auxiliary agent and a heat absorption foaming agent, the fire extinguishing main agent component in the powder plays a role in rapidly extinguishing fire, and the heat absorption foaming agent plays a role in cooling a thermal runaway battery; in a high-temperature fire scene, the flame-retardant auxiliary agent and the fire extinguishing main agent can generate a chemical reaction to generate a phosphate or borate material with a flame-retardant function, and the heat absorption foaming agent can generate a large number of bubbles in a high-temperature water loss process, so that a high-temperature product of the powder fire extinguishing agent forms a porous material, and a heat insulation function is fu
