The invention discloses inhibited mortar emulsion for fire prevention and extinguishment. The inhibited mortar emulsion is characterized by being prepared from high molecular inhibited expansive cement mortar and high molecular fire prevention and extinguishment inhibited emulsion, wherein the high molecular inhibited expansive cement mortar is prepared from 1 to 2 parts of high molecular materials and 3 parts of inorganic powder; the high molecular fire prevention and extinguishment inhibited emulsion is prepared from two or more of acrylic emulsion, vinyl acetate-ethylene copolymer emulsion, styrene-acrylate and a high molecular colloid fire extinguishment agent. The inhibited mortar emulsion for the fire prevention and extinguishment, disclosed by the invention, has the characteristics of easiness in preparation and convenience in use; the inhibited mortar emulsion for the fire prevention and extinguishment can be instantly prepared for instant use under a shaft, a large amount of pipelines needed for traditional grouting and glue injection are saved, the safety of coal mine production is increased, manpower, material resources and financial resources needed for fire extinguishment of the coal mine are reduced, and the workload of traditional grouting and glue injection for the fire prevention and extinguishment is greatly reduced.
