The invention discloses a perfluorohexanone fire extinguishing capsule and a preparation method thereof. The perfluorohexanone fire extinguishing capsule is composed of the following components in percentage by mass: 98.2-98.8% of a capsule core and 1.2-1.8% of a capsule shell, wherein the sum of the mass percentages of the above components is 100%. The capsule core consists of the following components: perfluorohexanone, aerosil, beta-cyclodextrin and water in a mass ratio of 1: (1-1.6): (0.05-0.08): (0.01-0.03). The capsule shell is obtained by drying a capsule wall material solution, and the capsule wall material solution consists of acrylic resin No. IV and ethanol in a mass ratio of 1: (5-28). According to the fire extinguishing capsule, liquid perfluorohexanone is effectively converted into solid for loading; the preparation process of the fire extinguishing capsule is stable; and the loading capacity of perfluorohexanone is large. When the fire extinguishing capsule is to be used, high dispersion of pe
