The invention discloses a flame-retardant and heat-conducting nanometer organic silicon insulating coating applied to a switch cabinet. The coating comprises, by mass, 30-70 parts of 107# room temperature vulcanized silicone rubber, 5-40 parts of flame retardant filler, 0.2-2 parts of modified intercalated hydrotalcite, 5-15 parts of silane coupling agent, 1-10 parts of crosslinking agent and 0.01-0.5 parts of catalyst. The invention also provides a preparation method and application of the coating above. Hydrolyzed alkane hydroxyl or silicon hydroxyl of the silane coupling agent reacts with Mg-OH or Al-OH on a hydrotalcite layer board and silicon hydroxyl on the surface of silica respectively to successfully prepare a hydrotalcite-silica mixed filler system, the improvement of the dispersion of the hydrotalcite in polymers is facilitated, the problem of damage to mechanical properties of polymer materials is solved, the 107# room temperature vulcanized silicone rubber is used in cooperation to improve the in
