The invention provides a nonstick pan coating layer, and a production method and a nonstick pan thereof. The production method comprises the following steps: mixing organosilicone resin, modified silicon carbide, nanometer calcium carbonate, mica powder, amino resin, a dispersant and a solvent, grinding the obtained mixture, dispersing the ground mixture, and filtering the dispersed mixture to obtain a coating; and spraying the coating on the surface of a metal pan matrix, and baking the sprayed metal pan matrix at 200-300DEG C for 10-30min to obtain the nonstick pan coating layer. The organosilicone resin, saturated modified silicon carbide and the nanometer calcium carbonate are simultaneously applied to the nonstick pan coating layer in order to form the coating layer with excellent performances of above three components. The modified silicon carbide has good thermal stability, corrosion resistance and thermal conduction performance, and guarantees the thermal distribution uniformity of the coating layer; the nanometer calcium carbonate makes the microscopic surface of the organosilicone coating layer be tight and have zero porosity, protects the matrix, and enhances the nonstick effect of the coating layer, and the nanometer calcium carbonate and the modified silicon carbide have synergism, and enhance the hardness and the heat resistance of the nonstick pan coating layer.
